Astronaut Mark Lee tests the new backpack called Simplified Aid for EVA Rescue (SAFER), a system designed for use in the event a crew member becomes untethered while conducting an EVA. The Lidar-In-Space Technology Experiment (LITE) is shown in the foreground. The LITE payload employs lidar, which stands for light detection and ranging, a type of optical radar using laser pulses instead of radio waves to study Earth’s atmosphere. Unprecedented views were obtained of cloud structures, storm systems, dust clouds, pollutants, forest burning, and surface reflectance. The STS-64 mission marked the first untethered U.S. EVA in 10 years, and was launched on September 9, 1994, aboard the Space Shuttle Orbiter Discovery.
