Kounotori 3
Kounotori 3 (Japanese: こうのとり3号機; English: "white stork" ), also known as HTV-3, was the third flight of the Japanese H-II Transfer Vehicle. It was launched on 21 July 2012 to resupply the International Space Station (ISS) aboard the H-IIB Launch Vehicle No. 3 (H-IIB F3) manufactured by Mitsubishi Heavy Industries (MHI) and JAXA. Kounotori 3 arrived at the ISS on 27 July 2012, and Expedition 32 Flight Engineer and JAXA astronaut Akihiko Hoshide used the International Space Station's Canadarm2 robotic arm to install Kounotori 3, to its docking port on the Earth-facing side (nadir) of the Harmony module at 14:34 UTC.
After the supplies are unloaded, Kounotori 3 was loaded with waste material from ISS, including used experiment equipment and used clothes. Then Kounotori 3 was unberthed from the ISS on 11 September 2012 and burned up upon reentering in the atmosphere of Earth on 14 September 2012.
Major changes of Kounotori 3 from previous Kounotori are:
The ground operation was improved to allow more late access cargo.
Kounotori 3 carries approximately 4,600 kilograms (10,100 lb) cargo, consisting of 3,500 kilograms (7,700 lb) in pressurized compartment and 1,100 kilograms (2,400 lb) in unpressurized compartment.
The pressurised cargo consists of system equipment (61%), science experiments (20%), food (15%), and crew commodities (4%). It includes: Aquatic Habitat (AQH), JEM Small-Satellite Orbital Deployer (J-SSOD), five CubeSats: (RAIKO, FITSAT-1, WE WISH, F-1, TechEdSat), i-Ball and REBR reentry data recorders, ISS SERVIR Environmental Research and Visualization System (ISERV). Additionally, loaded onto Kounotori 3's Resupply Racks was NASA's Water Pump Assembly (WPA) catalytic reactor to replace the former unit that broke in March 2012 in orbit and a cooling water circulation pump to replace the old unit in the Japanese Experiment Module (Kibō) that also broke at the end of March 2012.
The AQuatic Habitat (high-tech aquarium) (AQH) can be used to house small fish for up to 90 days. "As a result, aquatic breeding over three generations, from fish parents to grandkids, previously impossible in space shuttle experiments, has become a reality", NASA said in a press kit. The AQH experimental device allows scientists and researchers to observe the birth of space aquatic creatures that have never experienced Earth's gravity, enabling them to better understand how the space environment affects animals beyond generations in preparation for potential long-term space travel in future. Medaka (Oryzias latipes) will be bred and observed in the AQH experimental device.
Two experiments, originally designed by the winners of the international YouTube Space Lab competition, would examine how Bacillus subtilis and the Jumping spider would react to microgravity.
