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.
Low Earth OrbitUS-PM (Upravlenniye Sputnik Passivny Modifikirovanny) (also reported as US-PU) was a solar powered improved EORSAT (Electronic Ocean Reconnaissance Satellite). It used an passive ELINT devices to track naval vessels from space by registering their electronic emmissions.
Low Earth OrbitGalaxy 8-i is one of the most powerful satellites to join PanAmSat Corporation's fleet of spacecraft, with nearly 10 kilowatts of power at beginning of life. It is a Hughes HS-601HP body-stabilized model built by Hughes Space and Communications Company in El Segundo, Calif.

Low Earth OrbitTRMM (Tropical Rainfall Measuring Mission) is the first space mission dedicated to quantitatively measuring tropical and subtropical rainfall which is one of the most important and least-known parameters affecting the global climate system. ETS-VII (Engineering Test Satellite, "Kiku 7") was launched aboard the H-2 No. 6 rocket from Tanegashima Space Center in November 1997.mETS-VII itself comprises two satellites: "Orihime" and "Hikoboshi". "Orihime" is a target satellite weighing approximately 400 kilograms. It is placed in a fixed circular orbit at an altitude of roughly 550 kilometers. "Hikoboshi" is a chaser satellite, weighing some 2.5 tons. It moves in a variable orbit to rendezvous and dock with "Orihime". "Hikoboshi" is equipped with a six-jointed, three-clawed robot arm two meters long.
Low Earth OrbitSTS-87 was a Space Shuttle mission launched from Launch Complex 39B of the Kennedy Space Center on 19 November 1997. It was the 88th flight of the Space Shuttle, and the 24th flight of Columbia. The mission goals were to conduct experiments using the United States Microgravity Payload (USMP-4), conduct two EVAs, and to deploy the SPARTAN-201 experiment.
