Developed and built in Japan, the H-II Transfer Vehicle (HTV) known as "KOUNOTORI (white stork)" is an unmanned cargo transfer spacecraft that delivers supplies to the International Space Station (ISS).
Japan, the U.S., and Russia currently operate cargo transfers to the ISS. Among the supply vehicles, KOUNOTORI serves as the backbone of ISS operations with its world-leading supply capacity of approx. 6 metric tons, and is the only space liner capable of delivering large items of hardware.
Given its consistent on-time arrivals ever since the launch of the first technology demonstration mission, KOUNOTORI is widely acknowledged to be a safe and reliable vehicle, for which the world has high expectations regarding its operations.
The launch of KOUNOTORI5 is scheduled for 20:50, August 17, 2015 (Japan time).
The features, payload, and schedule of the HTV5 mission are updated.
At 11:29 p.m. (2:29 p.m. UTC), August 25, the CALET on the EP was transferred by the Kibo’s robotic arm (JEMRMS) and installed to the Kibo’s Exposed Facility (EF).
