Mission
TRMM & ETS 7
Type: Earth Science
TRMM (Tropical Rainfall Measuring Mission) is the first space mission dedicated to quantitatively measuring tropical and subtropical rainfall which is one of the most important and least-known parameters affecting the global climate system. ETS-VII (Engineering Test Satellite, “Kiku 7”) was launched aboard the H-2 No. 6 rocket from Tanegashima Space Center in November 1997.mETS-VII itself comprises two satellites: “Orihime” and “Hikoboshi”. “Orihime” is a target satellite weighing approximately 400 kilograms. It is placed in a fixed circular orbit at an altitude of roughly 550 kilometers. “Hikoboshi” is a chaser satellite, weighing some 2.5 tons. It moves in a variable orbit to rendezvous and dock with “Orihime”. “Hikoboshi” is equipped with a six-jointed, three-clawed robot arm two meters long.
Rocket
H-II – Mitsubishi Heavy Industries
Family: H-II
Length: 49 m
Diameter: 4 m
Launch Mass: 260 T
Low Earth Orbit Capacity: 10060 kg
The H-II was manufactured by Mitsubishi Heavy Industries with the first launch on 1994-02-03. H-II has 6 successful launches and 1 failed launches with a total of 7 launches. The H-II rocket was a Japanese satellite launch system which flew seven times between 1994 and 1999 with 5 successes. It was developed by NASDA in order to give Japan a capability to launch larger satellites in the 1990s. It was the first two stage liquid fuelled rocket Japan made using only domestic technologies.
Agency
Japan Aerospace Exploration Agency
Type: Government
Abbreviation: JAXA
Administration: Administrator: Hiroshi Yamakawa
Founded: 2003
Launchers: H-II
Country: JPN
The Japan Aerospace Exploration Agency (JAXA) is Japan’s national aero-space agency. Through the merger of three previously independent organizations, JAXA was formed on 1 October 2003. JAXA is responsible for research, technology development and the launch of satellites into orbit, and is involved in many more advanced missions, such as asteroid exploration and possible manned exploration of the Moon. JAXA launch their Epsilon vehicle from the Uchinoura Space Center and their H-II vehicles from the Tanegashima Space Center.
