In 1995, she was selected by NASA as part of the 15th Astronaut Training Group. The group was selected to provide pilots, engineers, and astronauts for space shuttle flights. After a year of training, she worked on technical issues for the Vehicle Systems and Operations Branch of the Astronaut Office. She also served as spacecraft communicator (
CAPCOM) in mission control during launch and entry for numerous missions. In 1997, she flew to space twice as a shuttle pilot on the missions
STS-83 (April 4 to 8, 1997) and
STS-94 (July 1 to 17, 1997). The STS-83 mission delivered to space a Microgravity Science Laboratory (MSL-1), a collection of 33 microgravity experiments housed inside the Spacelab. The goal of this mission was to test hardware, facilities, and procedures being developed in views of the long term research program on the future International Space Station. The mission, which was supposed to last 16 days was cut short because of problems with one of the Shuttle's three fuel cell power generation units. Mission duration was 95 hours and 12 minutes, traveling 1.5 million miles in 63 orbits of the Earth. In July 1997 the STS-83 mission was renamed as STS-94 and represented a re-flight of the MSL-1 Spacelab mission. This mission focused on materials and
combustion science research in microgravity. Mission duration was 376 hours and 45 minutes, traveling 6.3 million miles in 251 orbits of the Earth.Looking down at Earth from space the first time … it's like every dream come true. Even though you’ve seen pictures of Earth from space, it's not the same as being in space and looking at Earth. It was very rewarding. == Awards and honors ==
