controller performance, science platform pointing accuracy, antenna pointing accuracy, and spin rate accuracy. She worked in the areas of sequence development and testing as well. While at the Jet Propulsion Laboratory, Wilson also supported the Interferometery Technology Program as a member of the Integrated Modeling Team, which was responsible for finite element modeling, controller design, and software development. NASA Selected by NASA as an astronaut candidate in April 1996, Wilson reported to the Johnson Space Center in August 1996. Having completed two years of training and evaluation, she is qualified for flight assignment as a mission specialist. She was initially assigned technical duties in the Astronaut Office Space Station Operations Branch to work with Space Station payload displays and procedures. She then served in the Astronaut Office CAPCOM Branch, working in Mission Control as a prime communicator with on-orbit crews. Following her work in Mission Control, Wilson was assigned technical duties in the Astronaut Office Shuttle Operations Branch involving the Space Shuttle Main Engines, External Tank and Solid Rocket Boosters. Wilson has flown on three shuttle missions. On STS-121, Wilson flew aboard as a mission specialist. She also flew on the STS-120 mission that delivered the Harmony connecting module to the International Space Station. In April 2010, Wilson flew as a mission specialist on STS-131. On October 18, 2019, Wilson was ground controller at Houston for the first all woman spacewalk by Christina Koch and Jessica Meir On December 9, 2020, NASA announced that Stephanie Wilson was among the candidates for the Artemis program and if selected, she could be both the first woman and the first African-American on the Moon. Spaceflight experience STS-121 STS-121 (July 4–17, 2006), was a return-to-flight test mission and assembly flight to the International Space Station. During the 13-day flight, the crew of Space Shuttle Discovery tested new equipment and procedures that increase the safety of space shuttles, repaired a rail car on the International Space Station and produced never-before-seen, high-resolution images of the Shuttle during and after its July 4 launch. Wilson supported robotic arm operations for vehicle inspection, Multi-Purpose Logistics Module installation and EVAs and was responsible for the transfer of more than 28,000 pounds of supplies and equipment to the ISS. The crew also performed maintenance on the space station and delivered a new Expedition 13 crew member to the station. The mission was accomplished in 306 hours, 37 minutes and 54
