The Japanese Experiment Module (JEM), nicknamed Kibō, is a Japanese science module for the International Space Station (ISS) developed by JAXA. It is the largest single ISS module, and is attached to the Harmony module. The first two pieces of the module were launched on Space Shuttle missions STS-123 and STS-124. The third and final components were launched on STS-127.
The H-II Transfer Vehicle (HTV), also called Kounotori, is an expendable, automated cargo spacecraft used to resupply the Kibō Japanese Experiment Module (JEM) and the International Space Station (ISS). The Japan Aerospace Exploration Agency (JAXA) has been working on the design since the early 1990s. The first mission, HTV-1, was originally intended to be launched in 2001. It launched at 17:01 UTC on 10 September 2009 on an H-IIB launch vehicle. The name Kounotori was chosen for the HTV by JAXA because "a white stork carries an image of conveying an important thing, therefore, it precisely expresses the HTV's mission to transport essential materials to the ISS". The HTV is very important for resupplying the ISS because after the retirement of the Space Shuttle it is the only vehicle that can transfer new 41.3 in (105 cm) wide International Standard Payload Racks (ISPRs) and dispose old ISPRs that can fit the 51 in (130 cm) wide tunnels between modules in the US Orbital Segment.
Uncrewed spaceflights to the International Space Station (ISS) are made primarily to deliver cargo, however several Russian modules have also docked to the outpost following uncrewed launches. Resupply missions typically use the Russian Progress spacecraft, European Automated Transfer Vehicles, Japanese Kounotori vehicles, and the American Dragon and Cygnus spacecraft. The primary docking system for Progress spacecraft is the automated Kurs system, with the manual TORU system as a backup. ATVs also use Kurs, however they are not equipped with TORU. The other spacecraft — the Japanese HTV, the SpaceX Dragon and the Northrop Grumman Cygnus — rendezvous with the station before being grappled using Canadarm2 and berthed at the nadir port of the Harmony or Unity module for one to two months. Progress, Cygnus and ATV can remain docked for up to six months. Under CRS phase 2, Cargo Dragon docks autonomously at IDA-2 or 3 as the case may be. As of December 2022, Progress spacecraft have flown most of the uncrewed missions to the ISS.
RAIKO is a Japanese satellite which was built and operated by Tohoku and Wakayama Universities. A two-unit CubeSat, RAIKO was deployed from the International Space Station (ISS) on 4 October 2012, having been launched on 21 July 2012.
Kounotori 2, also known as HTV-2, was launched in January 2011 and was the second flight of the Japanese H-II Transfer Vehicle to resupply the International Space Station (ISS). It was launched by the H-IIB Launch Vehicle No. 2 manufactured by Mitsubishi Heavy Industries (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.
Technology Education Satellite (TechEdSat) is a successful nano-sat flight series conducted from the NASA Ames Research Center in collaboration with numerous universities. While one of the principal aims has been to introduce young professionals and university students to the practical realm of developing space flight hardware, considerable innovations have been introduced. In addition, this evolving flight platform has tested concepts for Low Earth Orbit (LEO) sample return, as well as planetary nano-sat class mission concepts.
ArduSat is an Arduino based nanosatellite, based on the CubeSat standard. It contains a set of Arduino boards and sensors. The general public will be allowed to use these Arduinos and sensors for their own creative purposes while they are in space.
Kounotori 3, 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 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.
Kounotori 4, also known as HTV-4, was the fourth flight of the H-II Transfer Vehicle, an uncrewed cargo spacecraft launched in August 2013 to resupply the International Space Station. It launched from Tanegashima Space Center aboard H-IIB No. 4 rocket on 3 August 2013 and connected to ISS by 9 August 2013; it carried 5,400 kilograms (11,900 lb) of cargo. Kounotori 4 undocked on 4 September 2013 and was destroyed by reentry on 7 September 2013.
Kounotori 5, also known as HTV-5, was the fifth flight of the H-II Transfer Vehicle, an uncrewed cargo spacecraft launched to resupply the International Space Station. It was launched on 19 August 2015.
The Nanoracks CubeSat Deployer (NRCSD) is a device to deploy CubeSats into orbit from the International Space Station (ISS).
Kounotori 6 (こうのとり6号機), also known as HTV-6, was the sixth flight of the H-II Transfer Vehicle, an uncrewed cargo spacecraft launched to resupply the International Space Station. It was launched at 13:26:47 UTC on 9 December 2016 aboard H-IIB launch vehicle from Tanegashima Space Center.
AESP-14 is a Brazilian 1U Cubesat developed by multiple Brazilian institutions. It was launched on 10 January 2015 aboard the SpaceX CRS-5 mission on a Falcon 9 v1.1 rocket. It was the first Brazilian Cubesat ever launched into space.
