Ares Quarterly Update Lithographs: July 2009



Vehicle Integration

Ares I is an in-line, two-stage rocket configuration topped by the Orion crew exploration vehicle and its launch abort system. In addition to the vehicle's primary mission -- carrying crews of astronauts to Earth orbit -- Ares I may also use its 25-ton payload capacity to deliver resources and supplies to the International Space Station.

First Stage

The launch vehicle's first stage is a single, five-segment reusable solid rocket booster, derived from the Space Shuttle Program's four-segment reusable solid rocket booster, which burns a specifically formulated and shaped solid propellant called polybutadiene acrylonitrile (PBAN). A newly designed forward adapter will mate the vehicle's first stage to the second, and will be equipped with booster separation motors to disconnect the stages during ascent. (Credit: NASA)



Upper Stage

Taking the Ares I on the second phase of its journey from Earth will be the spacecraft's upper stage, powered by the J-2X engine. A self-supporting cylindrical structure, the Ares I upper stage will be approximately 18 feet in diameter and 84 feet long. On the launch pad, the upper stage -- including the J-2X engine -- will account for approximately one-quarter of the total height of the Ares I. (Credit: NASA)




Upper Stage Engine


Powered by liquid oxygen and liquid hydrogen, the J-2X is an evolved variation of two historic predecessors: the powerful J-2 upper stage engine that propelled the Apollo-era Saturn IB and Saturn V rockets in the 1950s and 1970s, and the J-2S, a simplified version of the J-2 developed and tested in the early 1970's but never flown. The J-2X will measure about 185 inches long and 120 inches in diameter at the end of its nozzle. It will weigh approximately 5,300 pounds. With 294,000 pounds of thrust, the engine will enable the Ares I upper stage to place the Orion crew exploration vehicle in low-Earth orbit. (Credit: NASA)

NASA to Brief Media about Completion of Orion Vehicle Design Review

WASHINGTON -- NASA will host a teleconference Tuesday, Sept. 1, at 3 p.m. EDT to discuss the conclusion of the preliminary design review for the Orion crew exploration vehicle.

The preliminary design review is one of a series of reviews that occurs before hardware manufacturing may begin. As the review process progresses, detailed parts of the vehicle design are assessed to ensure the overall system can meet all NASA requirements for safe and reliable flight. The Orion Project's review process culminates in a board meeting held at NASA's Johnson Space Center in Houston beginning Aug. 31.

The briefing participants are:
-Geoff Yoder, director, Constellation Systems Division, NASA Headquarters, Washington
-Jeff Hanley, manager, Constellation Program, NASA's Johnson Space Center
-Mark Geyer, manager, Orion Project, NASA's Johnson Space Center

Reporters should contact Grey Hautaluoma at 202-358-0668, or Ashley Edwards at 202-358-1756, by noon Sept. 1 for dial-in information.
