STS-64 was Discovery's September 1994 Space Shuttle mission carrying the Lidar In-space Technology Experiment, SPARTAN-201 solar observatory, and several technology and life-science investigations. Richard Richards commanded the flight, L. Blaine Hammond Jr. served as pilot, and Jerry Linenger, Susan Helms, Carl Meade, and Mark Lee were mission specialists. LITE operated for 53 hours and returned more than 43 hours of high-rate atmospheric lidar data. The crew deployed and retrieved SPARTAN-201 for solar-corona and solar-wind observations, and Lee and Meade performed the first untethered U.S. spacewalk in ten years to test the Simplified Aid for EVA Rescue. Discovery launched from Launch Complex 39B on September 9 and landed on Runway 04 at Edwards Air Force Base on September 20.
