Twin Earth observation satellites, named for the explorers Meriwether Lewis (1774–1809) and William Clark (1770–1838), and selected as part of NASA's SSTI (Small Spacecraft Technology Initiative). Only Lewis was actually built and launched, on Aug. 23, 1997. However, once in orbit it span out of control and reentered about a month later.
