1997-074A
Part of NASA's Earth Probe series, the Tropical Rainfall Measuring Mission (TRMM) was built by GSFC as part of a joint NASA/NASDA project. It was launched in late 1997 on an H-II from Tanegashima. The satellite is 5m high and 14.5m span, with a launch mass of 3950 kg including 890 kg of fuel (however, at end of operations it was reported to have a dry mass of only 2621 kg. Its mission is to improve rainfall data for climate models, and study El Nino. In mid-2001 the orbit was raised to provide extended mission life.
