Endeavour launched from Kennedy Space Center on January 13, 1993 at 8:59 AM EST and landed at Kennedy on January 19 at 8:37 AM EST. The shuttle orbited 96 times at an altitude of 165 nautical miles at an inclination of 28.45 degrees. The mission lasted 5 days, 23 hours, 38 minutes, and 19 seconds.
The primary payload was the fifth Tracking and Data Relay Satellite (TDRS-F) which was deployed on day one of the mission. It was later successfully transferred to its proper orbit by the Inertial Upper Stage booster.
Also carried into orbit in the payload bay was a Hitchhiker experiment called the Diffuse X-ray Spectrometer (DXS). This instrument collected data on X-ray radiation from diffuse sources in deep space.
Other middeck payloads to test the effects of microgravity included the Commercial General Bioprocessing Apparatus (CGPA) for-life sciences research; the Chromosome and Plant Cell Division in Space Experiment (CHROMEX) to-study plant growth; the Physiological and Anatomical Rodent Experiment (PARE) to examine the skeletal system and the adaptation of bone to space flight; the Space Acceleration Measurement Equipment (SAMS) to measure and record the microgravity acceleration environment of middeck experiments; and the Solid Surface Combustion Experiment (SSCE) to measure the rate of flame spread and temperature of burning filter paper.
On day five, mission specialists Mario Runco and Greg Harbaugh spent nearly 5 hours in the open cargo bay performing a series of space-walking tasks designed to increase NASA’s knowledge of working in space. They tested their abilities to move about freely in the cargo bay, climb into foot restraints without using their hands and simulated carrying large objects in the microgravity environment.
Endeavor was crewed by Commander John H. Caspar, Pilot Donald R. McMonagle, and Mission Specialists Mark Runco, Gregory J. Harbaugh, and Susan J. Helms.
