Cosmonauts to Perform 27th Russian Space Station Spacewalk

Two Russian cosmonauts will venture outside the International Space Station on Jan. 21 to complete installation of a new high-speed data transmission system, remove an old plasma pulse experiment, install a camera for the new Rassvet docking module and retrieve a materials exposure package.

Expedition 26 Flight Engineers Dmitry Kondratyev and Oleg Skripochka are scheduled to float outside the Pirs airlock at 9:20 a.m. EST to begin the six-hour excursion. Both spacewalkers will wear Russian Orlan-MK spacesuits.

Kondratyev will be designated as Extravehicular 1 (EV1), with a red stripe on his suit, and Skripochka will be EV2, with a blue stripe on his suit. Skripochka also will wear a NASA-provided wireless television camera system and helmet lights to provide live point-of-view video to Mission Control-Moscow, which will provide ground support for the spacewalk. Mission Control-Houston will monitor the spacewalk as well.

Robonaut Flexes for the Camera

In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the dexterous humanoid astronaut helper Robonaut (R2) flexes its mechanical muscles during a media event hosted by NASA. R2 will fly to the International Space Station aboard space shuttle Discovery on the STS-133 mission. Although it will initially only participate in operational tests, upgrades could eventually allow the robot to realize its true purpose -- helping spacewalking astronauts with tasks outside the space station.

Backpack, Communications Network Face Desert Test

Science experiments don't always involve bubbling beakers and people dressed in lab coats and goggles. In the case of NASA's Desert RATS project, an experiment can look like a plastic box bolted to a backpack frame and be carried around the Arizona desert for a month.

Inside the plastic box is a host of off-the-shelf electronics capable of telling the backpacker where he is, letting him talk to distant colleagues and beaming pictures of notable objects to geologists and other scientists.

"The backpack tells you where you are, where you were and it allows you to communicate and share your experience with someone in a different location," said Marc Seibert, a senior research engineer at NASA's Kennedy Space Center. "This backpack has been dreamed about for 10 years."

The backpack is an important part of Kennedy's role in the Desert Research and Technology Studies project, which is set up as a large-scale experiment to find out what equipment and operations scenarios NASA needs to explore the surface of an alien world, such as an asteroid, the moon or Mars.

A team of astronauts, scientists and engineers from several NASA centers head to Arizona's desert each year to simulate the unique environment of space explorers. The effort is meant to test equipment and people to find out the best way to explore another world.

Kennedy's engineers develop the communications, navigation and data transmission networks needed, a task that includes a semitrailer set up as a mission operations center, a command vehicle, a specialized RV, a pair of Humvees plus enough communications gear to set up a wireless network for a small crew of explorers to talk back to "Earth" like they will from other planets.

Equipment from other centers, such as a pair of large rovers, has to work on the same communications network. The rovers, for example, relay the signals from the backpacks to the mission operations center.

Although the area they test in is not a perfect stand-in for the moon or Mars in terms of having breathable air and normal gravity, the site does a pretty good job of isolating the participants, said Mike Miller, communications research engineer at Kennedy.

"We have to take everything to the site, just like we will to other planet surfaces," Miller said.

The research program began 13 years ago, and grows in complexity with each annual run. The 2010 program is focused largely on seeing how effectively astronauts can explore a foreign surface under different communications scenarios and rover modes of operation. It also will put pressure on the scientists to have daily plans ready when the explorers awake each day. That means long nights of studying the day's findings to find out what should be done the next.

"This is probably the highest fidelity lunar simulation that's ever been done," Seibert said.

The backpack carries a pair of cameras, a GPS antenna to pinpoint location and all the electronics needed to store then transmit information. The person wearing the backpack controls its systems using an electronic wrist display, supplied by NASA's Glenn Research Center in Ohio, that is generations ahead of the flip cards Apollo astronauts used during the first trips to the moon. Researchers will also test an iPod Touch from NASA's Johnson Space Center in Houston.

Right now, the backpack and its host of attached gear only has to stand up to the winds and heat of a desert on Earth.

"Environment is a big thing out there," Miller said. "The winds are very high, it gets very hot. We are pretty much out in the middle of nowhere."

Designers don't have to worry just yet about the life support systems that would be required for any astronaut working on another world. The life support functions will be incorporated into the backpacks as they evolve and improve. Other parts of the backpack design will be incorporated into the rover so the astronauts can quickly leave the vehicle for a spacewalk.

Miller said the month-long exercise should show them whether the design works technically and what can be improved.

"Success would be to have all the systems up and working, for the scientists to get the science data and the test team to meet their objectives," Miller said.

Miller and his team were given the backpack assignment only a couple months before the equipment had to be assembled and shipped out.

"We only had two to three months here for everything, the design and building, getting the parts, everything," Miller said as others on his team put the finishing touches on a couple of backpacks.

With the short time frame, Miller said his group worked with Glenn partners and with off-the-shelf equipment to get the job done. The software for the controls was written from scratch to make the gear work with each other and operate to their needs.

"The whole communications infrastructure has been upgraded this year," Miller said.

The biggest challenge, he said, was keeping the weight down since the individual components could not be made from scratch by Miller's team.

Between excursions, the Desert RATS participants catalog what they've learned and look at ways to incorporate changes for the next one, along with passing on changes to other in-depth research programs NASA runs.

The backpack's capabilities are designed with space exploration in mind, but the arrangement may have applications for earthbound explorers, too. Basically, a geologist or other explorer could make a solo trek with the backpack and, on his return, play back the whole trip or selected highlights for those who weren't on the journey.

"Any explorer could use this backpack," Seibert said.

Star Wars Meets UPS as Robonaut Packed for Space

Getting into space isn't necessarily easy for astronauts, and it's not much easier for a robotic astronaut, either.

Cocooned inside an aluminum frame and foam blocks cut out to its shape, Robonaut 2, or R2, is heading to the International Space Station inside the Permanent Multipurpose Module in space shuttle Discovery's payload bay as part of the STS-133 mission.

Once in place inside the station, R2, with its humanlike hands and arms and stereo vision, is expected to perform some of the repetitive or more mundane functions inside the orbiting laboratory to free astronauts for more complicated tasks and experiments. It could one day also go along on spacewalks.

Making sure the first humanoid robot to head into space still works when it gets there has been the focus of workers at NASA's Kennedy and Johnson space centers. Engineers and technicians with decades of experience among them packing for space have spent the last few months devising a plan to secure the 330-pound machine against the fierce vibrations and intense gravity forces during launch.

Robonaut2 is designed as an assistant to astronauts on the International Space Station. But to to get there, it will need some assistance of its own from engineers and technicians on Earth. Photo credit: NASA

"I think back in May we realized we had a huge challenge on our hands," said Michael Haddock, a mechanical engineer designing the procedures and other aspects of preparing R2 for launch, including careful crane operations inside the Space Station Processing Facility's high bay.

Though it was fast-paced, intense work, the payoff of getting to help R2 into space added extra motivation for the engineers involved.

By spaceflight standards, planning for the packing effort moved quite quickly, particularly considering R2 is perhaps the heaviest payload to be taken into space inside a cargo module.

"The mass is what's driving the crane operations, otherwise we'd be handling the robot by hand," Haddock said. "But the robot itself weighs on the order of 333 pounds and when it is installed in the structural launch enclosure, it will weigh over 500 pounds."

As they must when loading anything for spaceflight, the engineers designed the packaging so astronauts could easily remove R2 from its launch box, known by its acronym SLEEPR or Structural Launch Enclosure to Effectively Protect Robonaut.

"We were trying to do something very unique and very fast," said Scott Higginbotham, payload manager for the STS-133 mission. "And we've got the best team in the world for dealing with things like that."

There was talk of simply strapping the robot into the empty seat on the shuttle's middeck, Higginbotham said, but R2 was too heavy for that. So the teams came up with a plan to fasten R2 to a base plate and use struts to support the back and shoulders. Then dense foam will provide more support, followed by an aluminum frame. A clamshell of foam tops off the package.

Assembling the packing precisely is important for R2 because a space shuttle accelerates to more than three times the force of gravity during its eight-minute climb into orbit.

"The team had to educate ourselves, learn the uniqueness of it as well as learn how to install it into the vehicle," said Ken Koby, lead systems engineer for Boeing. "That's what the team has basically been doing every day for the last three months, educating ourselves about Robonaut."

Coincidentally, detailed analysis showed that R2's best position to withstand the launch forces will be the same as the astronauts -- facing toward the nose of the shuttle with the back taking all the weight.

"The orientation is just like the crew flies," Koby said. "The crew will be facing straight up on their backs and Robonaut will be the same direction, obviously 30 feet behind them in the module here."

Although the robot is fundamentally a very complex machine full of state-of-the-art sensors and operated by phenomenally sophisticated software, it is its shape that stirs fascination. Designed by NASA and General Motors as a robotic assistant for astronauts working in space, R2 looks like the upper torso of a sculpted bodybuilder and is topped with a helmeted head that includes two cameras to give it three-dimensional vision plus other sensors.

Its look has been compared to Star Wars bounty hunter Boba Fett, the endoskeleton from the Terminator films and the animated robot that plays football on Fox Sports.

"It's rather intimidating at first sight because of its size, its physique and you can't see its eyes," Haddock said.

"From the moment you walk into the room and see R2, it's everything you'd expect from a robot, from the gold-shield face to the thickness, the broadness of his shoulders," Koby said. "It's truly very science fiction-like, but it's all fact in this case."

It also has a pair of beefy arms and two hands, complete with four fingers and one thumb each, that can shake hands. Its programming is sensitive enough to respond to a handshake with the same amount of force as the person squeezing R2's hands. In other words, it can hold a piece of equipment in space without crushing it.

"It really grabs people's attention," said Higginbotham. "It's so incredibly cool. It can use the same tools and procedures as an astronaut."

This Robonaut was not meant to fly at first. Instead, it was strictly a developmental model to be tested and perfected on the ground. However, it was adapted for flight and has tested well for launch. That is a bit of a theme for the STS-133 mission because the Permanent Multipurpose Module that Discovery is taking to the station also was retrofitted to add more capabilities. The PMM was formerly a Multipurpose Logistics Module known as Leonardo and was built to stay in space for only short periods at a time. But its mission has changed and engineers built up its armor and added some interior features so it can be permanently attached to the station and used as more of a storage closet than the moving van first envisioned.

"Someone said this mission is anything but ordinary," said Higginbotham, "and that is a fact."

Robot Goes to Work While Crew Prepares for Spacewalks

Robotics and spacewalk preparations took center stage Tuesday aboard the International Space Station as the Expedition 24 crew orbited above the Earth.

Dextre, an agile, two-armed extension for the station’s Canadarm2 robotic arm, continues its debut task to replace a failed Remote Power Control Module (RPCM) from a truss segment on the station’s port side. On Tuesday flight controllers in Houston began conducting a “dress rehearsal” of the actual replacement as they commanded Dextre to partially remove and reinstall an RPCM on the P1 truss. After Dextre successfully completes the test, Mission Control plans to swap the failed RPCM with a spare from the P3 truss Wednesday.

Meanwhile the Expedition 24 crew continued its own preparations to venture outside the station for an upcoming pair of spacewalks.

Cosmonauts Fyodor Yurchikhin and Mikhail Kornienko, both flight engineers, prepared the cooling loops of the Russian Orlan spacesuits they will wear during a six-hour spacewalk set to begin the evening of July 26. The pair will install Kurs automated rendezvous equipment on the exterior of the recently delivered Rassvet module to facilitate future dockings with Russian spacecraft.

Flight Engineers Doug Wheelock and Tracy Caldwell Dyson continued preparations for their Aug. 5 spacewalk as they each conducted a session of onboard training for Simplified Aid for EVA Rescue, or SAFER. Should a spacewalker become untethered during a spacewalk and begin floating away, the small nitrogen-jet thrusters of SAFER could help the astronaut get back to the station.

Shannon Walker, also a station flight engineer, assisted with the American spacewalk preparations as she inspected safety and waist tethers for structural integrity and reviewed spacewalk procedures.

The Expedition 24 crew also tackled a number of science investigations Tuesday. Commander Alexander Skvortsov spent part of his day working with a Russian experiment known as Russalka, which involves using a camera equipped with an ultraviolet filter to collect measurements of methane and carbon dioxide in the Earth’s atmosphere.

Wheelock prepared the Solution Crystallization Observation Facility for a Japanese study of facet-like crystallization. The results of this experiment may provide valuable data on creating high quality materials for industrial use such as superconducting magnets.

The Americans also continued maintenance work on the Oxygen Generation System, flushing the components that allow liquid to flow through the system so that oxygen can be extracted from recycled water to provide air for the crew to breathe.

Later, Walker assisted Wheelock with the latest session of Kids In Micro-Gravity!, an experiment that gives students a hands-on opportunity to design a demonstration that can be performed both in the classroom and aboard the station. Tuesday’s activity, a look at whether blowing across the tops of bottles filled with different amounts of water will create the same tones in space as on Earth, was developed by fifth grade students at Vaughan Elementary in Powder Springs, Ga.

Researchers can learn more about opportunities to develop and fly science experiments on the International Space Station (ISS) at the NASA ISS Research Academy Aug. 3-5 in League City, Texas.

Final Planned Flight of Atlantis Delivers New 'Dawn'

Space shuttle Atlantis thundered away from NASA's Kennedy Space Center on May 5, 2010 at 2:20 p.m. The on-time liftoff under a picturesque Florida sky was a perfect beginning to Atlantis' last scheduled mission, STS-132. The shuttle carried a six-person crew on a journey to deliver a new Russian module and several critical spare parts to the International Space Station.

"There are thousands of folks out there that have taken care of this bird for a long time," Commander Ken Ham said after Atlantis was cleared for launch. "We're going to take her on her 32nd flight, and if you don't mind, we'll take her out of the barn and make a few more laps around the planet."

Tucked into the shuttle's payload bay was the Russian-built Mini Research Module-1 known as "Rassvet," meaning "dawn." Nearly 20 feet long and weighing more than 17,700 pounds including its cargo, the module features eight workstations designed for a variety of science experiments and educational research.

The ambitious tasks ahead would be taken on by a crew of experienced space fliers. Ham was joined by Pilot Tony Antonelli, Mission Specialists Garrett Reisman, Michael Good, Steve Bowen and Piers Sellers.

During the astronauts' first full day in orbit, the standard inspection of the orbiter's protective thermal coverings was completed using a backup camera system when a snagged cable temporarily prevented use of the intended laser and digital cameras. Both the primary and backup systems are part of the orbiter boom sensor system that attaches to the shuttle's robotic arm.

Atlantis docked with the International Space Station on May 16, two days after liftoff. Ham guided the orbiter through a graceful backflip known as a "rendezvous pitch maneuver," giving station crew members the chance to take nearly 400 photos of the shuttle. Finally, the two spacecraft linked up at 10:28 a.m. EDT as the pair sailed 220 miles above the South Pacific Ocean.

Image above: Anchored to the Canadarm2, Mission Specialist Garrett Reisman holds a space-to-ground antenna during the mission's first spacewalk. Image credit: NASA

The hatches between shuttle and station were opened at 12:18 p.m. and the six STS-132 astronauts were welcomed aboard by the station's six residents: cosmonauts Oleg Kotov, Expedition 23 commander, Alexander Skvortsov and Mikhail Kornienko, Japan Aerospace Exploration Agency astronaut Soichi Noguchi, and U.S. astronauts T.J. Creamer and Tracy Caldwell Dyson.

"We've been here before, but it's bigger than we remember -- and, speaking for myself, better than I remember," Ham said as docked operations officially began. "I love this place!"

The combined crew got right to work, using the station's Canadarm2 robotic arm to remove a cargo carrier from Atlantis' open payload bay to the station's mobile transporter. Mounted on the carrier were important new equipment and spares to be installed during the mission's three spacewalks, including a backup space-to-ground antenna and six 375-pound batteries.

The first of the mission's three spacewalks started the next morning at 7:54 a.m. when Reisman and Bowen switched their spacesuits to battery power and floated out of the station's Quest airlock. Riding the station's robotic arm, Reisman carried the boom for the new antenna from the cargo pallet up to the Z1 truss and returned to the cargo pallet to grab the six-foot-wide

The pair then installed the antenna on the waiting boom, where it will help provide two-way data, voice and video communications for station residents. Reisman and Bowen added a spare-parts platform to the station's Dextre robotic arm and loosened the bolts holding the new batteries to the cargo carrier before wrapping up the 7-hour, 25-minute outing.

Installation of the Rassvet research module was the crew's next assignment. Ham and Antonelli used Atlantis' robotic arm to lift the nearly-20-foot-long component from the shuttle's payload bay, then handed it off to the station's robotic arm. Reisman guided the new module into the Earth-facing port on the Zarya module, achieving a flawless docking with one millimeter of clearance on either side of Rassvet's docking probe.

"Looks like a pretty good docking," Sellers reported to Mission Control. "Straight down the middle, got capture and contact."

Good joined Bowen for the second spacewalk, which got off to a head start at 6:38 a.m. May 19. First, Bowen fixed the snagged cable that had interfered with the early inspection of Atlantis' heat shield. After adjusting the cable and using a plastic tie to keep it in place, Mission Control announced the fix was successful.

Next, the astronauts installed four of six new batteries on the station's port 6 truss, the station's backbone, transferring the old batteries to the cargo carrier for the return trip to Earth. Good and Bowen tightened the bolts on the new space-to-ground antenna before coming back inside as the 7-hour, 9-minute spacewalk ended.

Hatches between the station and Rassvet were opened the following day, as Atlantis and crew finished the mission's first week and enjoyed a few hours of off-duty time.

The final two port 6 truss batteries were installed during the mission's third and final spacewalk. Good and Reisman swapped out the remaining batteries and installed a backup ammonia coolant line between the port 4 and port 5 truss segments. They also left a new power and data grapple fixture inside the Quest airlock. The fixture will be installed by the station crew on the exterior of the Zarya module this summer.

With all the mission's major tasks accomplished, Good and Reisman headed back to the airlock after working outside the station for 6 hours and 46 minutes.

The astronauts finished transferring equipment and supplies from Atlantis to the space station as the docked portion of the STS-132 mission drew to a close.

"Thank you, Ken, and thank you to the whole crew," said station Commander Kotov as the Atlantis and station crews prepared to part ways. "Thank you for an excellent job, for your patience, for your work -- for everything."

Ham answered, "Through our entire docked timeframe here, we were a 12-person crew that operated together, and that was the only way we got everything done. ...We've had a great time together."

Atlantis undocked from the station May 23 at 11:22 a.m. after a weeklong stay at the orbiting complex. The shuttle circled the station at a distance of 400 to 600 feet and finally pulled away with a separation burn an hour and 15 minutes later.

The late inspection of Atlantis' protective skin went off without a hitch, and the shuttle was cleared to land.

Atlantis touched down at 8:48 a.m. May 26, gliding smoothly along Kennedy's Runway 33 after 186 orbits and nearly 12 full days in space. With Ham and Antonelli at the controls, the orbiter returned to its home port for what was planned to be the last time. During its 25 years of spaceflight, Atlantis completed 32 missions and traveled more than 120 million miles.

"We've all flown on Atlantis now, and some of us have flown on her a couple of times. She's a great ship," Antonelli said hours after landing, adding that it was a "real honor" to be on what may be its last flight. "We're happy to bring her back home to you here in Florida."

Tiny Technology With a Big Heart

When undergoing medical treatment, physicians frequently determine that a patient's vital signs need to be monitored. This includes closely monitoring things like blood pressure and heart rate. For most patients today, this means a variety of wires and sensors will be attached to their bodies. But thanks to technology developed at NASA, there might be a better way.

A new biomedical sensor which incorporates technology pioneered at NASA's Glenn Research Center in Cleveland, Ohio, is currently being developed by a company called Endotronix. The company is investigating using the sensors to measure blood pressure and heart rate.

"When this opportunity came about, we immediately understood that we could tailor our technology for a biomedical application. It was an opportunity for direct societal impact that could assist a lot of people in the medical community," says Dr. Félix Miranda, one of the two Glenn scientists responsible for the technology.

The sensors are about the size of the head of a pin—1 millimeter wide and .5 millimeter thick. Crafted out of gold and silicone, each tiny sensor also includes a multi-turn loop antenna, which means data collected from the sensor can be wirelessly transmitted to an external unit. Called Biomedical Microelectromechanical Systems, or Bio-MEMS, each sensor makes use of NASA patented radiofrequency technology.

Developed for Space, Used on Earth

Dr. Félix Miranda, a supervisory electronics engineer, and Dr. Rainee Simons, a supervisory physicist, are both part of the Communications, Instrumentation and Controls Division at Glenn. In 2001, the Technology Transfer and Partnership Office (TTPO) at Glenn awarded the team $50,000 to work towards finding a way to use Glenn's radiofrequency technology in the biomedical field.

"It is a testament to how much you can do with a small amount of seed money—how you can leverage that," Miranda says. "The center has gotten an acceptable return on investment on this effort, and it has given us satisfaction because we have been able to evolve technology."

Initially, the two were investigating the technology for potential use in space suits, as a way to remotely monitor astronauts' health. The initiative was especially important for astronauts performing space walks, and could prove essential as plans develop to send astronauts further into space.

"There is an emphasis to develop sensors for astronauts that are convenient as well as accurate. Safety is the initial motivation," Simons says.

Drs. Miranda and Simons achieved patents for their work in 2003 and 2007, and extensively published their work. Through these publications, Dr. Anthony Nunez, a cardiovascular surgeon and president of Endotronix, learned about the work at Glenn in 2006.

"Unlike other devices, ours is very small," Miranda says. "[Dr. Nunez] was very impressed by that, and decided that this was the technology he needed for his cardiovascular products."

Endotronix now holds the exclusive license for cardiovascular applications of the Glenn technology. Glenn and Endotronix signed a Space Act Agreement to work on developing and validating the technology for these particular medical uses. Though the Space Act Agreement has now ended, Endotronix keeps Drs. Miranda and Simons updated on their progress.

"We want [Endotronix] to succeed. That is what NASA's 'For the Benefit of All' is all about," Miranda says.

Monitoring and Wireless Transmitting

The cardiovascular sensors will operate by being implanted in the body of the patient. Each tiny unit doesn't require a battery, which means the unit can last indefinitely in the body while causing less damage to surrounding tissue and lessening the risk of infection or toxicity. The device, manufactured out of biocompatible materials, operates by sensing the pressure that the heart or an artery creates when the blood flows by a membrane. It transmits data to a small, portable external reader, which can be worn by the patient or kept nearby for readings. This transmission occurs wirelessly, and the absence of a wire in the body also helps prevent risk of infection and other negative side effects.

The tiny, 1 millimeter by 1 millimeter antenna, provides wireless signals of exceptional strength.

Because the sensors are so small, they are not disruptive to the patients in whom they are implanted. All types of patients can potentially benefit from the device, from nursing home residents requiring intensive care to active patients who wish to travel, while still monitoring their health. The external readers are easy to use, allowing patients to take their own readings.

"As this technology evolves to be a product for the general public, it needs to be as simple as possible without sacrificing the accuracy of the information," Miranda says.

Building Bridges and Beyond

Drs. Miranda and Simons have received many accolades for their work. In October of 2009, the two were runners-up in the Wall Street Journal's Technology Innovation Awards, in the wireless category. They also won a 2010 Northeast Ohio Technology Coalition Innovation Award (NorTech Award) for their work, and received commendations from the Ohio State Senate and the Secretary of the State of Ohio.

Endotronix has licensed the technology for cardiovascular applications, but there are other potential uses for these pressure sensors. Companies have expressed interest in investigating the technology for other biomedical areas, such as general surgery and bone, neck and spine health. Other areas of human interest, like structural safety in bridges and buildings, could also benefit from this technology.

"We still have opportunities based on this concept that we'd like to explore, and the agency environment is consistent with this kind of effort. There are good opportunities ahead," Miranda says. "We can really tailor the concept to support diverse applications."

Impacting the Community

The technology, used for both aerospace and non-aerospace applications, is notable. It is the second largest licensing of intellectual property at Glenn and has pioneered a new area of collaboration with the commercial sector.

"This is the very first medical and surgical application for space biosensor technology," Simons says.

Drs. Miranda and Simons are pleased with how their research has been integrated into the medical field, and they are looking forward to seeing what new areas—biomedical and beyond—the sensors may influence.

"It is very gratifying to see that work like this found its way to some commercial use," Simons says. "The technology is doing good for the community, which is very satisfying."

New Video "GOES" Exploring the Sun's Weather

The series of Geostationary Operational Environmental Satellites known as GOES provide daily satellite images of weather here on Earth, but they also provide scientists with solar data and space weather observations in geosynchronous (over a fixed location on Earth's surface) orbit. NASA has just released a four-minute educational video called "A Weather Satellite Watches the Sun" explaining the uses of space weather instruments on the GOES satellites.

"The GOES space weather instruments provide crucial data for determining the intensity of space weather events reported by forecasters using the National Oceanic and Atmospheric Administration (NOAA) Space Weather Scales," said Howard Singer, Chief Scientist, Space Weather Prediction Center, Boulder, Colo.

The four-minute video was produced by Silvia Stoyanova, a visualizer at NASA's Goddard Space Flight Center in Greenbelt, Md. The video provides information about space weather, interviews with astronaut Paul Richards, NASA GOES Deputy Project Manager Andre' Dress, NOAA's Space Weather Prediction Center Chief Scientist Howard Singer and many others to explain the importance of space weather and monitoring space weather changes.

NOAA manages the operational environmental satellite program and establishes requirements, provides all funding and distributes environmental satellite data for the United States. NASA's GOES Project located at NASA's Goddard Space Flight Center in Greenbelt, Md., procures and manages the development and launch of the GOES series of satellites for NOAA on a cost reimbursable basis. NASA's GOES Project also creates some of the GOES satellite images and GOES satellite imagery animations.

GOES satellites continually monitor the solar and near-Earth space conditions and provide real-time data to scientists, forecasters, and space weather customers on Earth.

"Space weather" means the conditions on the sun, in the solar wind, and in the space surrounding Earth that affects human activities and technological systems. Space weather can affect satellite operations, cell phone reception, Global Positioning System (GPS) use, and power grids. NASA even uses the GOES satellite data to ensure that astronauts in the space shuttle, space station or on space walks are safe from solar particle events. Commercial airlines that fly polar routes also need to know about solar weather as it affects the ionosphere and high-frequency communications that they rely on at high latitudes.

There are two GOES satellites that cover weather conditions in the U.S. and they are positioned over the eastern and western U.S. GOES-13 is the satellite in the GOES EAST position that covers weather on the eastern side of the continental U.S., including the Atlantic Ocean and Gulf of Mexico. GOES-11 is in the GOES WEST position and covers the western half of the U.S. and the Eastern Pacific Ocean.

GOES-13 has a Space Environment Monitor that consists of three instrument groups: an energetic particle sensor (EPS) package, two magnetometer sensors, and a solar x-ray sensor (XRS) and extreme ultra-violet sensor (EUVS).

The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles, and is used to provide alerts and warnings of hazardous conditions. The magnetometer sensors measure the Earth's magnetic field and provide alerts of changes in the solar wind.

The XRS is an x-ray telescope that observes and measures the sun's solar x-rays in order to provide alerts for potential disruptions in radio communications and degradation in GPS signals. The EUVS is an extreme ultra-violet sensor that measures ultraviolet emissions from the sun. These ultraviolet emissions heat the Earth's upper atmosphere and affect the drag on low-orbiting spacecraft.

The final instrument on GOES satellites that helps monitor space weather is called the Solar X-Ray Imager, or SXI. Every minute the SXI captures an image of the sun's atmosphere in X-rays and provides the space weather forecasters with the necessary information to forecast alerts of potential harmful conditions to space and ground systems.

Those three Space Environment Monitor instrument groups and the SXI operate at all times providing real-time data to the Space Weather Prediction Center (SWPC).

The SPWC is the nation's civilian "space weather" center. SPWC receives, monitors, and interprets a wide variety of solar terrestrial data and issues reports, alerts, warnings, and forecasts for special events such as solar flares and geomagnetic storms.

NASA to Launch Human-Like Robot to Join Space Station Crew

NASA will launch the first human-like robot to space later this year to become a permanent resident of the International Space Station. Robonaut 2, or R2, was developed jointly by NASA and General Motors under a cooperative agreement to develop a robotic assistant that can work alongside humans, whether they are astronauts in space or workers at GM manufacturing plants on Earth.

The 300-pound R2 consists of a head and a torso with two arms and two hands. R2 will launch on space shuttle Discovery as part of the STS-133 mission planned for September. Once aboard the station, engineers will monitor how the robot operates in weightlessness.

R2 will be confined to operations in the station's Destiny laboratory. However, future enhancements and modifications may allow it to move more freely around the station's interior or outside the complex.

"This project exemplifies the promise that a future generation of robots can have both in space and on Earth, not as replacements for humans but as companions that can carry out key supporting roles," said John Olson, director of NASA's Exploration Systems Integration Office at NASA Headquarters in Washington. "The combined potential of humans and robots is a perfect example of the sum equaling more than the parts. It will allow us to go farther and achieve more than we can probably even imagine today."

The dexterous robot not only looks like a human but also is designed to work like one. With human-like hands and arms, R2 is able to use the same tools station crew members use. In the future, the greatest benefits of humanoid robots in space may be as assistants or stand-in for astronauts during spacewalks or for tasks too difficult or dangerous for humans. For now, R2 is still a prototype and does not have adequate protection needed to exist outside the space station in the extreme temperatures of space.

Testing the robot inside the station will provide an important intermediate environment. R2 will be tested in microgravity and subjected to the station's radiation and electromagnetic interference environments. The interior operations will provide performance data about how a robot may work side-by-side with astronauts. As development activities progress on the ground, station crews may be provided hardware and software to update R2 to enable it to do new tasks.

R2 is undergoing extensive testing in preparation for its flight. Vibration, vacuum and radiation testing along with other procedures being conducted on R2 also benefit the team at GM. The automaker plans to use technologies from R2 in future advanced vehicle safety systems and manufacturing plant applications.

"The extreme levels of testing R2 has undergone as it prepares to venture to the International Space Station are on par with the validation our vehicles and components go through on the path to production," said Alan Taub, vice president of GM's global research and development. "The work done by GM and NASA engineers also will help us validate manufacturing technologies that will improve the health and safety of our GM team members at our manufacturing plants throughout the world. Partnerships between organizations such as GM and NASA help ensure space exploration, road travel and manufacturing can become even safer in the future."

Endeavour to Deliver a Room With a View

The International Space Station has been moving steadily closer to completion for the past several years. But what house is complete without a utility room, a gym and a picture window?

During the STS-130 mission, space shuttle Endeavour will deliver the Tranquility node and its cupola, a dome-shaped extension from Tranquility made up of seven windows. They will be the last major U.S. modules to be added to the space station, and together they’ll help clear out premium workspace in other areas of the station – as well as offer a window on the world.

At 15 feet wide and 23 feet long, the Tranquility node will provide a centralized home for the station’s environmental control equipment – one of the systems that remove carbon dioxide from the station’s air, one of the station’s bathrooms and the equipment that converts urine into drinkable water, all of which is currently taking up space in the Destiny laboratory. And there’s enough room left over to house the station’s new treadmill and its microgravity equivalent of a weight machine, moving it out of the Unity node where it’s in the way whenever spacewalk preparations are going on inside the adjacent Quest airlock.

“It gives us a much needed addition to the house, so to speak,” said Bob Dempsey, lead space station flight director for the mission. “We’re getting to the point where we’re really cramped for space. You might be surprised at that, considering we’re essentially the volume of a 747 and we’ve been adding modules for the last couple of years. You might think we’d be sitting around in a big empty house. But no – every inch is really getting packed up there.”

STS-130 Commander George Zamka put it another way.

“It’s like exercising in the office,” he said. “This will be a more logical organization, more focused.”

Though the node has an intensely practical function, there are still fanciful aspects to Tranquility. For one, its name, which was chosen with the help of a naming contest on NASA.gov.

“It harkens back to the Sea of Tranquility, where humans made their very first tentative landing on the moon,” Zamka said. “They were only there for a few hours, and it was at the very limits of what human beings could do. From that beginning, we’re now putting up a node that will house the majority of the life support equipment for the station, where we’re going to have a permanent presence in space.”

But everyone agrees that the real scope for the imagination will be provided by Tranquility’s 6.5-by-5-foot annex: the cupola. Its true purpose will be to provide a true view of robotics operations on the station’s exterior – such as those that will be required when the next module, the Russian Rassvet, is added during STS-132 – and in that it will be invaluable.

“Out the window is the truth,” Zamka said. “The video views that we use now, you’re trying to stick together and have a mental image of where things are. When you look out the window, you don’t have to imagine. It’s all right there for you.”

But there’s no question that many people – including Zamka – are looking forward to looking out of it for other views.

“Just the idea of providing this great view of the station and the world beneath us is going to be pretty great,” he said. “That’s not what it’s for, but it will be spectacular.”

The cupola will be like a mini control tower sticking out from the Tranquility node, as opposed to the other station windows, which are flush with the station’s exterior. Its seven windows – one in the center and six around the sides – will provide the only views of the outside of the station from the inside, in particular the Russian and Japanese sections. And with the station just about finished, there’s more to see out there than ever.

So, Zamka said, in addition to the robotic operations and Earth views it will provide, it will also give us a good look at some of the space shuttle fleet’s finest handiwork as the program comes to an end. And that provides its own cause for reflection.

“We’ve come a long way in human spaceflight because of the shuttle’s capability,” he said. “We’ve launched and retrieved satellites, we’ve done medical research and now we’ve built this huge space station. We’re almost to the point of passing the baton from the space shuttle to the space station in terms of what our human spaceflight experience will be now.”

Kwatsi Alibaruho, lead STS-130 space shuttle flight director, said that even with so much left to do in the program’s final five flights, he was making it a point to spend some time thinking about the subject.

“It’s very easy to get into a routine, to lose oneself in the hustle and bustle of trying to get the work done,” Alibaruho said. “But the shuttle is a unique spacecraft. I find myself thinking a lot about how I’m going to describe this time to my son when he’s old enough to understand. There has never been an operational spacecraft like it before and all indications are that it will be some time before there will be one like it again. I find myself really appreciative of the opportunity I’ve had to serve in this capacity.”

NASA Astronaut John Grunsfeld, Instrumental to Hubble Telescope Repair, Will Help Oversee its Science Operations

NASA astronaut John Grunsfeld, who participated in three spaceflights to service the Hubble Space Telescope, is leaving the agency to become the deputy director of the Space Telescope Science Institute in Baltimore. The institute is the science operations center for Hubble and the James Webb Space Telescope, which is planned for launch in 2014.

"During the past 18 years, John has been a true asset to the agency," said NASA Administrator Charles Bolden, a former astronaut who few on the STS-31 mission that deployed the Hubble. "Some have called him the chief Hubble repairman, but I call him a friend and wish him the best in his new endeavor."

In addition to Grunsfeld's flights to Hubble (STS-103 in Dec. 1999, STS-109 in March 2002, and STS-125 in May 2009), he also served on two other shuttle missions. He performed eight critical spacewalks and logged more than 835 hours in space.

During 2003 and 2004, he was NASA's Chief Scientist at the agency's headquarters in Washington. He helped develop the Vision for Space Exploration, which set NASA on the path for future exploration endeavors.

Mission STS-129: Delivering the Goods

Space shuttle Atlantis' STS-129 mission was an ambitious and demanding undertaking that began Nov. 16, 2009, with a spectacular and on-time liftoff at 2:28 p.m. EST from NASA's Kennedy Space Center in Florida.

Aboard were Commander Charles O. Hobaugh, Pilot Barry E. Wilmore, Mission Specialists Leland Melvin, Mike Foreman, Robert L. Satcher Jr. and Randy Bresnik. In addition to the crew, there were nearly 30,000 pounds of replacement parts packed in the Express Logistics Carriers, or ELCs, secured inside Atlantis' payload bay.

With a picture-perfect launch behind them, the first task at hand on Nov. 17 was checking the shuttle's wing leading edges and nose cap using the orbiter boom sensor system. The end of the boom consists of cameras and lasers, giving experts on the ground 3-D views of the shuttle's heat shield to ensure there wasn't any damage from launch.

Later in the day while the shuttle was catching up with the International Space Station, Bresnik, Foreman and Satcher checked out the two spacesuits they would use for the three planned spacewalks.

Once in range of the station on Nov. 18, the shuttle was delicately maneuvered into the rendezvous pitch maneuver, or "backflip," where Expedition 21 Flight Engineers Jeffrey Williams and Nicole Stott took photos from their vantage point.

Images from the first and second inspection were sent back to Earth for experts to review, making sure the shuttle would have a safe flight back through Earth's atmosphere.

Hobaugh then carefully guided Atlantis closer to the station until it was locked into the station's docking port on the Harmony node. It took a couple hours for a series of hatch leak checks to be performed and once accomplished, the hatches were opened and the Atlantis crew was enthusiastically greeted and welcomed aboard the station by the Expedition 21 team.

As the hatch opened, Nicole Stott's responsibilities as station flight engineer officially ended and she became an STS-129 mission specialist for the remainder of her time in space. Stott is the last NASA astronaut to experience the rotation of launching from and being returned to Earth by a space shuttle. In the future, a Russian Soyuz spacecraft will be used for station crew rotations.

With a demanding to-do list ahead of them, the two crews began with the first task at hand. ELC 1 was grappled from Atlantis' payload bay by Melvin and Bresnik with the shuttle's robotic arm and handed off to the station's robotic arm controlled by Wilmore and Williams. The platform was permanently installed to the outside of the station to store large cargo.

That evening Foreman and Satcher spent the night camping out in the Quest airlock preparing for their first spacewalk. After stepping out into space the next day, Foreman and Satcher completed all major tasks almost two hours ahead of schedule. In addition, Foreman was able to successfully connect a cable on the Unity node -- one that was uncooperative for the STS-128 crew in September.

Inside the station, work was ongoing to prepare for the arrival of the Tranquility node, which will be flown on shuttle Endeavour's STS-130 mission targeted for early 2010.

Overnight, a false depressurization alarm sounded and woke the crew, but flight control teams on the ground determined there was no danger to the station or crew. In the STS-129 post-landing crew press conference, said, "The training the crew members received helped them deal with the false alarms that went off a few times during their stay on the orbiting outpost."

The relocation of supplies and equipment between Atlantis and the station continued Nov. 20, in addition to tackling a variety of maintenance, troubleshooting and science activities -- keeping both station and shuttle crews busy.

Early the next morning, the second carrier with almost 10,000 pounds of large spare parts, including an attitude-control gyroscope, was moved from the shuttle's cargo bay to its permanent location on the S3 side of the station's truss, or backbone.

The two platforms that were attached to the station allow additional storage space for the mountain of supplies and equipment needed for the smooth and efficient running of the orbiting laboratory, now and well into the future after the shuttles are retired.

A little later, Foreman and Bresnik made their way into the emptiness of space for the second successful spacewalk of the mission. They not only completed their tasks ahead of schedule but also accomplished some get-ahead jobs -- all in six hours, eight minutes.

Meanwhile, another success story was in the making. On the morning of Nov. 22, Bresnik was told by the Mission Control Center in Houston that his wife, Rebecca, had given birth to their daughter, Abigail Mae Bresnik. He was assured that both baby and mother were doing just fine. Atlantis' crew members were given a well-earned, half day off to celebrate. The rest of day was dedicated to preparing for the third spacewalk on Nov. 23, featuring Satcher and Bresnik.

The space excursion began more than an hour later than planned because a drinking-water valve in Satcher's spacesuit became dislodged and the helmet had to be opened to reattach the valve. With the fix behind them, Bresnik and Satcher completed all the tasks in just five hours, 42 minutes -- almost on time, regardless of the late start.

Later, the last of the mission's spare hardware was moved thanks to the combined effort of all 12 shuttle and station crew members.

On Nov. 22, the shuttle and station crew members said their final farewells before the hatches between shuttle Atlantis and the station were securely closed -- after which the shuttle crew prepared for undocking.

Wilmore eased the shuttle away from the station circling around the outpost. Crew members videoed and snapped photos of the orbiting laboratory in order to assess its exterior condition.

One more survey was in store for the shuttle's heat shield with Wilmore and Melvin using the orbiter boom sensor system -- a five-hour process.

Atlantis crew members spent part of Thanksgiving preparing for their Nov. 27 landing date. They tested the thruster jets that control the shuttle's orientation in space and during early re-entry, as well as the flaps and rudders that guide it through the atmosphere.

The day didn't pass without a surprise, though. A traditional turkey dinner with all the trimmings found its way aboard Atlantis before undocking -- compliments of the Expedition 21 crew members.

It was a perfect end to a nearly perfect mission. After the twin sonic booms echoed and Atlantis came out of a clear-blue sky, the vehicle and crew touched down on Kennedy's Shuttle Landing Facility on Nov. 27 at 9:44 a.m. EST.

After winding up a successful 11-day flight to deliver spare parts, other equipment and supplies to the International Space Station, the crew took their last walk around the vehicle that served them well from start to finish.

After a short ride to crew quarters, the astronauts were given a thorough medical exam and met with their families. On Nov. 28, the crew flew home to Houston, and on Nov. 30, they were honored at a homecoming ceremony held at nearby Ellington Field.

Atlantis' STS-129 mission was the 31st flight dedicated to space station assembly, resupply and maintenance -- one that should help keep the station supplied well into the future.

Space Shuttle Crew Returns Home after 11-Day Mission

CAPE CANAVERAL, Fla. -- Space shuttle Atlantis and its crew of seven astronauts ended an 11-day journey of nearly 4.5 million miles with a 9:44 a.m. EST landing Friday at NASA's Kennedy Space Center in Florida.

The mission, designated STS-129, included three spacewalks and the installation of two platforms to the International Space Station's truss, or backbone. The platforms hold large spare parts to sustain station operations after the shuttles are retired. The shuttle crew delivered about 30,000 pounds of replacement parts for systems that provide power to the station, keep it from overheating, and maintain a proper orientation in space.

STS-129 Commander Charlie Hobaugh was joined on Atlantis' STS-129 mission by Pilot Barry Wilmore and Mission Specialists Leland Melvin, Randy Bresnik, Mike Foreman and Bobby Satcher. Atlantis returned with station resident Nicole Stott, who spent 91 days in space. This marks the final time the shuttle is expected to rotate station crew members.

A welcome ceremony for the astronauts will be held Monday, Nov. 30, in Houston. The public is invited to attend the 4 p.m. CST event at Ellington Field's NASA Hangar 990. Highlights from the ceremony will be broadcast on NASA Television's Video File. For NASA TV downlink information, schedules and links to streaming video, visit:

With Atlantis and its crew safely home, the stage is set for launch of shuttle Endeavour on its STS-130 mission, targeted to begin in February. Endeavour will deliver a pressurized module, known as Tranquility, which will provide room for many of the space station's life support systems. Attached to the node is a cupola, a robotic control station with six windows around its sides and another in the center that provides a 360-degree view around the station.

Inventors Answer Call for New Glove Designs

Two independent inventors answered NASA's call for innovative new designs for the next generation of astronaut gloves. Today's spacewalkers have to contend with bulky gloves that stiffen when pressurized, making it tough to grip and flex while completing tasks in the vacuum of space.

Peter Homer and Ted Southern put their prototypes to the test during NASA's 2009 Astronaut Glove Challenge, held Nov. 19 at the Astronaut Hall of Fame in Titusville, Fla., near NASA's Kennedy Space Center.

Homer, an engineer from Southwest Harbor, Maine, was awarded $250,000 after placing first. Southern, a sculpture major at New York's Pratt Institute, earned second place and $100,000.

The ultimate goal of the Astronaut Glove Challenge is to improve the current design, resulting in a stronger and more flexible glove that will reduce the hand fatigue experienced by astronauts working in space.

For the first Astronaut Glove Challenge held in 2007, competitors supplied only the inner pressure-restraining layer. The outer layer, which provides protection against extreme temperatures and micrometeoroids, was an added requirement this year. Representatives from NASA and the agency's spacesuit contractor, ILC Dover, observed and noted the gloves' performances in a series of three tests.

The competitor inserted his gloved arm and hand into a depressurized glove box for the dexterity and flexibility test, completing cycles of movements and tasks, such as gripping a handle, using tools, flexing the hand and wrist, and touching the tip of the thumb to the tip of each finger.

In the joint force test, test operators from ILC Dover sealed and pressurized each glove to 4.3 pounds per square inch (psi) of internal pressure, then tugged it through its full range of motion while measuring the amount of force each movement required.

Finally, the gloves' strength capabilities were measured in the burst test. The room quieted as test operators sealed the glove and filled it with water, slowly increasing the pressure. Competitors, judges and other spectators leaned forward, watching the glove for signs of weakness or rupture.

The event was sponsored by Secor Strategies LLC of Titusville, Fla., and non-profit Volanz Aerospace of Owings, Md., managed the event for NASA.

"Both of you did better than the (current) Phase VI glove, and you both get a round of applause for that," said Alan Hayes, Volanz Aerospace chairman. "The test results were incredibly close."

Both Homer and Southern began working on the project in spring 2006 and competed in the first Astronaut Glove Challenge. Homer took home $200,000 after winning that event. After the 2007 challenge, Southern teamed up with former competitor Nikolay Moiseev.

Prior to the challenge, competitors were in the dark about who else would participate or what their designs might be.

"You're sort of developing in the vacuum of your own little world," Homer said. "You're hoping that you're going far enough with your design. And then there's the aspect of, 'Who am I going to be going up against?' I didn't know Ted was competing until we walked in and saw each other."

The Astronaut Glove Challenge is one of six Centennial Challenges prize competitions managed by NASA's Innovative Partnerships Program.

First STS-129 Spacewalk Complete

Spacewalkers Mike Foreman and Robert Satcher completed a 6-hour, 37-minute spacewalk at 4:01 p.m. EST.

After finishing all their scheduled chores with two hours to spare, Foreman and Satcher were assigned a task that had been planned for the second spacewalk. They deployed the outboard Payload Attach System on the Earth-facing side of the Starboard 3 truss, after overcoming some initial difficulties.
