Station-Bound Cargo Craft Launches from Japan

H-IIB launch vehicle carrying Japan's Kounotori3 cargo craft
The Japan Aerospace Exploration Agency (JAXA) H-II Transfer Vehicle, or HTV3, launched aboard an H-IIB launch vehicle from the Tanegashima Space Center in southern Japan at 10:06 p.m. EDT Friday (11:06 a.m. Saturday, Japan time) to begin a weeklong journey to the International Space Station. The 16.5-ton HTV3, also known as Kounotori3, or “white stork,” is carrying almost 4 tons of supplies, food and experiment hardware for the orbital outpost. At the time of launch, the station was 255 statute miles over the south Pacific off the coast of Chile.

When Kounotori3 catches up with the station on July 27, the spacecraft will be commanded to fly within about 40 feet while Expedition 32 Flight Engineers Joe Acaba of NASA and Aki Hoshide of JAXA use Canadarm2, the station's Canadian Space Agency-provided robotic arm, to grapple the vehicle and berth it to a docking port on the Earth-facing side of the Harmony node. Grapple is scheduled to begin at 8:04 a.m. The installation process to berth HTV3 to the station begins at 10:45 a.m.

HTV3 is a 33-foot-long, 13-foot-diameter (10 meter by 4 meter) unmanned cargo transfer spacecraft capable of delivering both internal and external supplies and hardware to the station. Among the items being delivered to the station is a remote-controlled Earth-observing camera system called the International Space Station SERVIR Environmental Research and Visualization System, or ISERV. Once installed, the system will be directed by researchers on the ground to acquire imagery of specific areas of the world for disaster analysis and environmental studies.
