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.
Spaceflight experience in
Destiny during
STS-114. (Aug 2005)
STS-67 Endeavour (March 2–18, 1995) was the second flight of the ASTRO observatory, a unique complement of three telescopes. During this 16-day mission, the crew conducted observations around the clock to study the far ultraviolet spectra of faint astronomical objects and the polarization of ultraviolet light coming from hot stars and distant galaxies. Mission duration was 399 hours and 9 minutes.
STS-86 Atlantis (September 25 to October 6, 1997) was the seventh mission to rendezvous and dock with the Russian Space Station Mir. Highlights included the exchange of U.S. crew members
Mike Foale and
David Wolf, a spacewalk by
Scott Parazynski and
Vladimir Titov to retrieve four experiments first deployed on Mir during the
STS-76 docking mission, the transfer to Mir of 10,400 pounds of science and logistics, and the return of experiment hardware and results to Earth. Mission duration was 169 orbits in 259 hours and 21 minutes.
STS-91 Discovery (June 2–12, 1998) was the 9th and final Shuttle-Mir docking mission and marked the conclusion of the joint U.S./Russian Phase I Program. Mission duration was 235 hours, 54 minutes.
STS-114 Discovery (July 26 – August 9, 2005) was the first "Return to Flight" mission following the Space Shuttle
Columbia disaster. Highlights included the first in-flight repair to the orbiter during a
spacewalk. Mission duration was 333 hours, 33 minutes. == Awards and honors ==
