NAME: Tracy E.Caldwell (Ph.D.)
NASA Astronaut

PERSONALDATA: BornAugust 14, 1969 in Arcadia, California. Recreational interests include running,weight training, hiking, softball, basketball, and auto repair/maintenance. Asan undergraduate, she competed in intercollegiate athletics on CSUF’s trackteam as both a sprinter and long jumper.

EXPERIENCE: As an undergraduate researcher atthe California State University, Fullerton (CSUF), Dr. Caldwell designed,constructed and implemented electronics and hardware associated with alaser-ionization, time-of-flight mass spectrometer for studying atmospherically-relevantgas-phase chemistry. Also at CSUF, she worked for the Research andInstructional Safety Office as a lab assistant performing environmentalmonitoring of laboratories using hazardous chemicals and radioactive materials,as well as calibrating survey instruments and helping to process chemical andradioactive waste.

During thattime (and for many years prior) she also worked as an electrician/insidewireman for her father’s electrical contracting company doing commercial andlight industrial type construction. At the University of California, Davis, Dr.Caldwell taught general chemistry laboratory and began her graduate research.Her dissertation work focused on investigating molecular-level surfacereactivity and kinetics of metal surfaces using electron spectroscopy, laserdesorption, and Fourier transform mass spectrometry techniques. She alsodesigned and built peripheral components for a variable temperature, ultra-highvacuum scanning tunneling microscopy system.

In 1997, Dr.Caldwell received the Camille and Henry Drefus Postdoctoral Fellowship inEnvironmental Science to study atmospheric chemistry at the University ofCalifornia, Irvine. There she investigated reactivity and kinetics ofatmospherically relevant systems using atmospheric pressure ionization massspectrometry, Fourier transform infrared and ultraviolet absorptionspectroscopies. In addition, she developed methods of chemical ionization forspectral interpretation of trace compounds. Dr. Caldwell has published andpresented her work in numerous papers at technical conferences and inscientific journals.

Dr. Caldwellis a private pilot and conversational in American Sign Language (ASL) andRussian.

NASAEXPERIENCE:Selected by NASA in June 1998, Dr.Caldwell reported for training in August 1998. Astronaut Candidate Training includedorientation briefings and tours, numerous scientific and technical briefings,intensive instruction in Shuttleand InternationalSpace Station (ISS) systems, physiological training, ground school toprepare for T-38 flight training, as well as learning water and wildernesssurvival techniques. Completion of this training and evaluation qualified herfor flight assignment as a mission specialist.

In 1999, Dr.Caldwell was first assigned to the Astronaut Office ISS Operations Branch as aRussian Crusader, participating in the testing and integration of Russianhardware and software products developed for ISS. In 2000, she was assignedprime Crew Support Astronaut for the 5th ISSExpedition crew, serving as their representative on technical andoperational issues throughout the training and on-orbit phase of their mission.

During ISS Increments4-6, Dr. Caldwell also served as an ISS spacecraft communicator (CAPCOM) insideMission Control. In 2003, she transitioned to the Astronaut Shuttle OperationsBranch and was assigned to flight software verification in the Shuttle AvionicsIntegration Laboratory (SAIL) and also worked supporting launch and landingoperations at Kennedy Space Center, Florida. She served as Lead CAPCOM for Increment11. Dr. Caldwell is assigned to the crewof STS-118 targeted for launch in 2007. STS-118 will deliver to the stationthe third starboard truss segment, an external stowage platform, and logisticsand supplies in a SPACEHAB single cargo module.
