Iridium 9

 1997-030C

---

Iridium SV009 was one of seven launched on a Krunichev Proton in Jun 1997 into the second of six Iridium orbital planes, 30 deg E of the first plane. Mass was 657 kg for each satellite. NK's report may imply all seven satellites were ejected at the same time.

4600 kg for seven satellites. Assume 500 kg for the adapter and 14600 kg for the Blok DM for a total inorbit mass of 19700 kg full. DV1 is 100 m/s; DV2 is 1.8km/s, mostly plane change. hence expect mass of 19140 and 11380 kg, leaving 6280 kg in the DM, so 3000 kg of prop unaccounted. Prop used is 560 and 7760 kg, at 22.8 kg/s this corresponds to 24 and 340s burn times. Actual burn times were 25s and 291s, corresponding to prop of 570 and 6635 kg, so the reconstruction seems not too far off.
