STS-58
STS-58 was a NASA mission flown by Space Shuttle Columbia launched from Kennedy Space Center, Florida, on October 18, 1993. The missions was primarily devoted to experiments concerning the physiological effects in space. This was the first in-flight use of the "Portable In-flight Landing Operations Trainer" (PILOT) simulation software. It was also the last time Columbia would land at Edwards Air Force Base, California. The mission also attracted controversy for experiments involving the dissection of live rats in space.
STS-58 was a 1993 shuttle mission dedicated to life sciences research. Columbia's crew performed a series of experiments to gain knowledge on how the human body adapts to the weightless environment of space. Experiments focused on cardiovascular, regulatory, DNA, neurovestibular and musculoskeletal systems of the body. The experiments performed on Columbia's crew and on laboratory animals (48 rats held in 24 cages), along with data collected on the SLS-1 mission (STS-40) in June 1991, will provide the most detailed and interrelated physiological measurements acquired in the space environment since the Skylab program in 1973 and 1974.
Crew members conducted experiments aimed at understanding bone tissue loss and the effects of microgravity on sensory perception. Two neurovestibular experiments investigating space motion sickness and perception changes were performed on the 2nd day as well. Astronauts Lucid and Fettman wore a headset, called an Accelerometer Recording Unit (ARU), designed to continually record head movements throughout the day.
Only one minor issue came up on October 19, 1993, associated with a circuit breaker that tripped, cutting off power temporarily to one of the rodent cages in the module. Flight controllers in Houston reported it was not caused by a short in the electrical system and the breaker was reset, restoring power to the cage.
McArthur and Blaha began using the Lower Body Negative Pressure device on flight day 3 (FD 3), which is being tested as a countermeasure for the detrimental effects of microgravity. All three flight crew members will collect urine and saliva samples and keep logs of their exercise and food and fluid intake as part of the Energy Utilization detailed supplementary objective. DSO 612 looks at the nutritial and energy requirements of crew members on long-duration space flights and the relationship between fluid and food consumption.
On October 20, 1993, though the space toilet is working fine, the crew detected a slight leak around the filter door before going to bed. They removed the filter and cleaned up about a teaspoon of water — much less than had been expected. As a precaution, a secondary fan separator unit was used to separate fluid from the air before cycling the air back into the cabin through the filter.
On October 21, 1993, Mission specialists Margaret Rhea Seddon (Payload commander), Shannon Lucid and David Wolf and Payload specialist Martin Fettman collected additional blood and urine samples for the series of metabolic experiments. Some of the samples will follow-up on the calcium absorption experiment performed on October 20, 1993. The experiment, sponsored by Dr. C. D. Arnaud of the University of California, San Francisco, studies the mechanisms of how calcium is maintained and used in bone metabolism in space. Based on preliminary results from the 1991 SLS-1 mission (STS-40), Dr. Arnaud believes the decrease in bone density is due to increased bone breakdown that is not compensated for by a subsequent increase in bone formation.
On October 22, 1993, using the on-board ham radio called SAREX-2 for Shuttle Amateur Radio Experiment, Blaha and Searfoss contacted school children at the Sycamore Middle School in Pleasant View, Tennessee, Gardendale Elementary in Pasadena, Texas and Naparima College in Trinidad and Tobago on November 4, 1993. The Standard Interface Rack (SIR), was tested by Searfoss to demonstrate that equipment can be removed from one rack location and reintegrated into another by a single crew member during orbital operations while maintaining reliable mechanical, data and power interfaces.
