Summary
Iridium 04 to 08 launched on an United States Air Force Delta II 7920-10C from Space Launch Complex 2W, Vandenberg SFB, CA, USA on May 5, 1997. It was United States Air Force's 976th launch, 4th this year and humanity's 4,139th orbital launch attempt. It was the 1st Delta II 7920-10C flight. The payload was bound for low Earth orbit (LEO). Iridium 8, one of 6 catalogued objects, reached a 633 × 650 km orbit inclined 86.4°. 6 objects from this launch are catalogued, 5 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.
