Astronomically Awesome Astronauts
Sally Ride: A Trailblazing Physicist in Space
An astronomically awesome astronaut who studied physics is the first American woman in space, Sally Ride. She began her journey into higher education at Swarthmore College in Pennsylvania in 1968 majoring in Physics on a full-ride scholarship for her tennis skills. After three semesters at Swarthmore, she felt she could better pursue her interests in her home state, California, and began considering options to transfer universities. Ride began studying quantum mechanics at the University of California, Los Angeles as the sole female Physics major in the program and excelled in her courses. For her junior year, she transferred a final time to Stanford University where she completed her Bachelor of Science in Physics and Bachelor of the Arts in English Literature in 1973. She continued her studies and earned a Master of Science in Physics in 1975, specializing in astrophysics and free-electron lasers. Ride also earned a Doctorate in Philosophy in 1978.
In January of 1977, she came across a newspaper advertisement searching for new Astronaut Candidates which strongly urged women to answer the call so that the first American woman could be sent to space. When faced with this monumental opportunity, Sally Ride sent in a request for the paperwork and filled out her application without hesitation. Her depth of knowledge in physics and bold tenacity shined through. She was chosen to be an Astronaut Candidate a year later in January of 1978 and completed her training in August of 1979! During the astronaut training program, she was particularly interested in the flight training which drove her to pursue a private pilot’s license. After completing training she and 34 other candidates were added to the pool of active astronauts eligible for space missions.
As an active Astronaut, Sally Ride completed missions STS-7 in 1983 and STS-41-G in 1984, both on the space shuttle Challenger. On her first mission, STS-7, Ride performed as a spacecraft communicator (CAPCOM) and helped develop and operate robotic arm equipment, Shuttle Remote Manipulator System (RMS). She showed remarkable adaptation to the zero-gravity environment. Mission STS-41-G launched with the directive to deploy a satellite and conduct scientific observations of Earth. A third mission, STS-61-M, was scheduled for Astronaut Ride, but the Challenger disaster in 1986 prevented future missions. With her two missions, physicist astronaut Sally Ride spent over 343 hours in space.
Don Thomas: Exploring Space with a Physics Degree
Another out-of-this-world physicist and Astronaut is Don Thomas who flew on STS-65, STS-70, STS-83, and STS-94. After he graduated from high school in Cleveland Heights, Ohio, Thomas earned a Physics degree at Case Western Reserve University in 1977. He continued his educational journey at Cornell University to earn a master’s in 1980 and a doctorate in 1982 in Materials Science with specialized studies in crystalline formations and abnormalities. Following his graduation, Thomas worked on a technical development team for AT&T and as a professor at Trenton State College in New Jersey. In 1987, he left AT&T to work for Lockheed Engineering where part of his job was to review Space Station payloads. Shortly after, in 1988, Don Thomas joined NASA as a Materials Engineer. He also used his specialized area of study to act as a Principal Investigator to observe changes in crystal growth when disturbed by microgravity.
Thomas had applied to become an astronaut and was turned down twice, so he earned his pilot’s license and invested more in education to give him an extra draw in the next application process. After being declined one final time he was accepted for the astronaut training process in 1990 and became Astronaut Don Thomas in July 1991. Astronaut Thomas was assigned his first mission STS-65 which launched July 8, 1994, on space shuttle Discovery. The mission flew the second International Microgravity Laboratory (IML-2) and conducted more than 80 experiments focusing on materials and life sciences research in microgravity. On July 13, 1995, he launched mission STS-70, also on space shuttle Discovery. This mission required Astronaut Thomas to oversee the deployment of the last in a series of six Tracking and Data Relay Satellites.
His third mission, STS-83, took place on space shuttle Columbia on April 4, 1997, but was cut short due to technical problems. Astronaut Thomas’ fourth and final mission, STS-94, took place on July 1, 1997, on the space shuttle Columbia. This mission was a do-over of the STS-83 Microgravity Science Laboratory (MSL-1) Spacelab mission and focused on materials and combustion science research in microgravity. In total, Astronaut Don Thomas has logged over 1,040 hours in space. Presently, Higher Orbits is proud to have Astronaut Thomas as one of our featured astronauts at our Go For Launch! programs!
