Kounotori 2


Active Cargo Unmanned Payload Capacity: 6000 kg
Destination: International Space Station
Serial Number: HTV-2

Kounotori 2 , also known as HTV-2, was launched in January 2011 and was the second Japanese H-II Transfer Vehicle to resupply the International Space Station (ISS). It was launched by the H-IIB Launch Vehicle No. 2 (H-IIB F2) manufactured by MHI and JAXA. After the supplies were unloaded, Kounotori 2 was loaded with waste material from ISS, including used experiment equipment and used clothes. Kounotori 2 was then unberthed and separated from the ISS and burned up upon reentering the atmosphere on 30 March 2011.
