USA-191

 2006-050A


The S-17 spacecraft, F-17 mission was launched by a Boeing Delta 4 from Vandenberg. Target orbit was 1734LT SSO.

A large number of debris objects were cataloged associated with the Delta 4 deorbit burn.

Sirius 2

 1998-056B


Nordiska Sat. HS-376 high power. NSAB is joint venture of SSC, Tele Danmark and Teracom AB. Will replace Sirius 1. 15 Ku-band tsp. To be built at Hughes/El Segundo. Launch Oct 98 to 5E, colocate with Sirius 1. Lease to SES-Astra at 28E for one year. Then move to 5E for NSAB service.

Launch mass 1420 kg, 815 kg BOL, 630 kg dry. Size 2.16d 3.32m high, 7.76m deployed

Prelaunch plan was for apogee burn at T+58:30 or on Oct 8 at around 0920. At 0851 on Oct 8 according to TLEs, the satellite crossed the equator at 24E and 35869 km altitude. Working back from the Oct 13 TLEs the satellite would have been at 10.7E at that time, but the Oct 17 TLEs match very well for a burn at 0850 UTC. I hypothesize that the Oct 13 TLEs are spurious.
