Launched
April 7, 1998
Summary
Iridium 62 to 68 launched on a Khrunichev State Research and Production Space Center Proton-K/17S40 from 81/23 (81L), Baikonur Cosmodrome, Republic of Kazakhstan on April 7, 1998. It was Khrunichev State Research and Production Space Center's 52nd launch, 1st this year and humanity's 4,229th orbital launch attempt. It was the 4th Proton-K/17S40 flight and the 1st this year. The payload was bound for low Earth orbit (LEO). Iridium 62, one of 7 catalogued objects, reached a -788 × 1,719 km orbit inclined 88.1°. 7 objects from this launch are catalogued, all 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.
