Selected by NASA in March 1992, Lawrence reported to the Johnson Space Center in August 1992.
She completed one year of training and was qualified for flight assignment as a Mission Specialist.
Her technical assignments within the Astronaut Office have included flight software verification in the Shuttle Avionics Integration Laboratory (SAIL), Astronaut Office Assistant Training Officer, and Astronaut Office representative for Space Station training and crew support.
She flew as the ascent/entry flight engineer and blue shift orbit pilot on STS-67 (March 2–18, 1995).
She next served as Director of Operations for NASA at the Gagarin Cosmonaut Training Center in Star City, Russia, with responsibility for the coordination and implementation of mission operations activities in the Moscow region for the joint U.S./Russian Shuttle/Mir program.
In September 1996 she began training as a crew member for a 4-month mission on the Russian Space Station Mir.
However, she was replaced by David Wolf due to concerns over minimum size requirements for the Russian Orlan EVA suit.
Because of her knowledge and experience with Mir systems and with crew transfer logistics for the Mir, she flew on STS-86 (September 25 to October 6, 1997) and STS-91 (June 2–12, 1998).
A veteran of four space flights, she logged over 1,200 hours in space.
Lawrence was a Mission Specialist on the crew of STS-114.
She was in charge of the transfer of supplies and equipment and operated the Space Station robotic arm on the Return To Flight mission during which the crew tested and evaluated new procedures for the inspection and repair of the Space Shuttle thermal protection system.
The mission launched on July 26, 2005 and landed on August 9, 2005.


Captain Lawrence retired from NASA in June 2006.
