This close-up of astronaut and mission specialist Kathryn Thornton was captured under water in the Marshall Space Flight Center (MSFC) Neural Buoyancy Simulator (NBS) where she is participating in a training session for the STS-61 mission. The NBS provided the weightless environment encountered in space needed for testing and the practices of Extravehicular Activities (EVA). Launched on December 2, 1993 aboard the Space Shuttle Orbiter Endeavor, STS-61 was the first Hubble Space Telescope (HST) serving mission. During the 2nd EVA of the mission, Thornton, along with astronaut and mission specialist Thomas Akers, performed the task of replacing the solar arrays. The EVA lasted 6 hours and 35 minutes.

This STS-61 onboard photo depicts Astronaut and mission specialist Kathryn Thornton performing the 2nd extra-vehicular activity (EVA) of the STS-61 mission.

Activities inside the laboratory module during the Spacelab-3 mission are shown in this photograph. Left to right are astronauts Robert Overmyer, Commander of the mission; Don Lind, Mission Specialist; Lodewijk van den Berg, Payload Specialist; and William Thornton, Mission Specialist. The primary purpose of the Spacelab-3 mission was to conduct materials science experiments in a stable low-gravity environment. In addition, the crew did research in life sciences, fluid mechanics, atmospheric science, and astronomy. Spacelab-3 was equipped with several new minilabs, special facilities that would be used repeatedly on future flights. Two elaborate crystal growth furnaces, a life support and housing facility for small animals, and two types of apparatus for the study of fluids were evaluated on their inaugural flight. Spacelab-3 (STS-51B) was launched aboard the Space Shuttle Challenger on April 29, 1985. The Marshall Space Flight Center had managing responsibilities of the mission.

CAPE CANAVERAL, Fla. – At the Kennedy Space Center's Apollo/Saturn V Center, former NASA astronauts William Thornton, left, and Karol Bobko recall experiences during the Astronaut Scholarship Foundation's event celebrating the 40th anniversary of Skylab. Along with astronaut Robert Crippen, Thornton, and Bobko, took part in a 56-day activity during 1972 called SMEAT -- Skylab Medical Experiment Altitude Test -- that preceded the launch of Skylab and helped NASA evaluate equipment and procedures proposed for the long-duration Skylab missions. Thornton and Bobko went on to fly missions during the Space Shuttle Program. The gala commemorating the 40th anniversary of Skylab included six of the nine astronauts who flew missions to America's first space station. The orbiting laboratory was launched unpiloted from Kennedy on May 14, 1973. Between May 25, 1973 and Feb. 8, 1974, crews of three spent 28, 59 and 84 days living and working in low-Earth orbit aboard the station.

S73-33858 (November 1973) --- A close-up view of the feet of scientist-astronaut William E. Thornton as he demonstrates the use of a treadmill-like exercise device which was developed for maintaining the leg and back muscles of the Skylab 4 crewman. Thornton is in the Skylab Orbital Workshop simulator in Building 5 at the Johnson Space Center. The Skylab 2 and Skylab 3 astronauts had no exercise device onboard capable of adequately maintaining their leg and back muscles. The treadmill device consists of a Teflon-coated aluminum plate or sheet bolted to the floor of the Skylab Orbital Workshop. The crewmen will wear the bicycle ergometer harness while exercising. Bungee cords attached to the floor and to the harness will supply the downward pressure or force for the back and leg muscles. The astronaut's feet will slide over the Teflon-coated plate as he "marches in place." Photo credit: NASA
