Echostar 1

 1995-073A

---

The second AS7000 launched from China in quick succession, Echostar 1 was a direct broadcast TV satellite for Echostar Satellite Corp., a subsidiary of Echosphere Corp of Denver, Colorado. In 1998 the FCC ordered Echostar 1 and 2 to be moved to their legally allocated positions of 118.8W and 119.2W. In 2009 Echostar 1 was moved to 77W to provied QuetzSat service for Mexico. It was retired in 2018.

The satellite had a launch mass of 3287 kg and carried dual Leros engines.

Rossi X-Ray Timing Explorer

 1995-074A

---

The Bruno B. Rossi X-Ray Timing Explorer (RXTE) was intended for studies of the time variability and spectra of bright X-ray sources in the hard X-ray (2 keV and above). Known before Mar 1996 as simply XTE, the satellite used a bus built at NASA-Goddard with steerable solar arrays, reaction wheels, and high gain TDRS antennae to allow all-sky access and rapid maneuvrability. The bus was 5.8 x 1.8 x 1.8m in size. It could point to 6 arcmin with a 10 degree per minute slew rate; mass of XTE was 2955 kg. XTE was named after Bruno Rossi (1905-1993), a former MIT physicist who was one of the founders of X-ray astronomy.

Launch was postponed many times because of the Koreasat launch problem and because of weather delays. The first ignition attempt on Dec 22 was aborted when a frozen LOX valve prevented main engine ignition. Launch finally came on 1995 Dec 30.

The satellite was retired in 2012 after a successful career.
