Summary
Iridium 27 to 33 launched on a Khrunichev State Research and Production Space Center Proton-K/17S40 from 81/23 (81L), Baikonur Cosmodrome, Republic of Kazakhstan on September 14, 1997. It was Khrunichev State Research and Production Space Center's 48th launch, 6th this year and humanity's 4,171st orbital launch attempt. It was the 3rd Proton-K/17S40 flight. The payload was bound for low Earth orbit (LEO). Iridium 29, one of 664 catalogued objects, reached a 514 × 529 km orbit inclined 86.6°. 664 objects from this launch are catalogued, 7 of them payloads.

About this launch
Iridium provides global mobile telecommunications services using a constellation of 66 low earth orbit satellites in a 86.4° inclined orbit. Although 77 satellites were originally envisioned for the system and spawned the name based on the 77th element in the periodic table, the system has been scaled back. Motorola's Satellite Communications Group designed and manufactured the Iridium satellites with Lockheed Martin providing the LM-700A spacecraft buses.
