Toward the STS-88 mission's end, the astronauts deployed a small 590-pound satellite called SAC-A for the Argentinean National Committee of Space Activities. Equipped with five technology experiments, SAC-A was ejected from a canister in Endeavour's cargo bay at 10:31 p.m. (CST) as the satellite flew over the northern Indian Ocean. The satellite is expected to remain in orbit from five to nine months sending back data to Argentine researchers on Earth.
