Landsat 7, NASA's newest Earth-observing satellite, launched without a hitch on April 15, 1999, at 2:32 p.m. EST from Vandenberg Air Force Base, California. As part of NASA's Earth Observing System and Earth Science Enterprise, Landsat 7 continues the 27-year legacy of gathering Earth surface images from space.
The 4,800 pound (2,177 kilogram) satellite was attached to a Boeing Delta II booster and soared smoothly into the sky where it settled into a near polar orbit 438 miles (705 kilometers) high.

Earth science satellites are designed to study our home planet’s surface and atmosphere, but occasionally they capture views of other objects in low-Earth orbit such as satellites, the International Space Station, and rocket debris.
