JERS-1

 1992-007A

---

Japan's first Earth Resources Satellite, ERS-1 or JERS-1, was built by Mitsubishi as a joint project of NASDA and the Ministry of International Trade and Industry (MITI). Its on-orbit name was Fuyo (Japanese for `Rose Mallow'). The 1340 kg (1400 kg?) satellite had a 3.1 x 0.9 x 1.8 m bus, with a 8 x 3.4m solar paddle spanning 11.4m. The SAR antenna was 11.9m x 2.4m. The spacecraft was controlled from Tsukuba.

CANYON 6 was another launch that caused much confusion. Some initial press reports gave the launch vehicle as a Titan IIIC, and this error was propagated into the 1990s by the RAE Tables, although the TRW Space Log (1975 and subsequent editions) consistently gave the correct identification. The confusion over the launch vehicle caused observers to speculate that the satellite was the first of a new generation, possibly the CIA ARGUS or Advanced Rhyolite satellite (now thought to have been cancelled). It was clearly a signals intelligence payload because of the secrecy surrounding the launch, and until recently the Rhyolite series was the only such contemporary geostationary payload known.
