Military career 
During medical school she did active duty training with the Diving Medicine Department at the United States Navy Experimental Diving Unit in March 1987. After completing medical school, Clark underwent postgraduate medical education in pediatrics from 1987 to 1988 at the National Naval Medical Center. The following year she completed Navy undersea medical officer training at the Naval Undersea Medical Institute in Groton, Connecticut, and diving medical officer training at the Naval Diving and Salvage Training Center in Panama City, Florida. Clark was designated a Radiation Health Officer and Undersea Medical Officer. She was then assigned as the Submarine Squadron 14 Medical Department Head in Holy Loch, Scotland. During that assignment she dove with Navy divers and Naval Special Warfare Unit Two SEALs and performed many medical evacuations from US submarines. After two years of operational experience she was designated as a Naval Submarine Medical Officer and Diving Medical Officer.
Clark underwent six months of aeromedical training at the Naval Aerospace Medical Institute in Pensacola, Florida, and was designated as a Naval Flight Surgeon. She was stationed at MCAS Yuma, Arizona, and assigned as Flight Surgeon for a Marine Corps AV-8B Night Attack Harrier Squadron (VMA-211). She made several deployments, including one overseas to the Western Pacific, practiced medicine in austere environments, and flew on multiple aircraft. Her squadron won the Marine Attack Squadron of the Year award for its successful deployment. She was then assigned as the Group Flight Surgeon for the Marine Aircraft Group 13.
Before her selection as an astronaut candidate she served as a Flight Surgeon for the Naval Flight Officer advanced training squadron (VT-86) in Pensacola, Florida. Clark was Board Certified by the National Board of Medical Examiners and held a Wisconsin Medical License. Her military qualifications included Radiation Health Officer, Undersea Medical Officer, Diving Medical Officer, Submarine Medical Officer, and Naval Flight Surgeon. She was a Basic Life Support Instructor, Advanced Cardiac Life Support Provider, Advanced Trauma Life Support Provider, and Hyperbaric Chamber Advisor.
NASA career 
Selected by NASA in April 1996, Clark reported to the Johnson Space Center in Houston, Texas in August 1996. After completing two years of training and evaluation, she was qualified for flight assignment as a mission specialist. From July 1997 to August 2000 Clark worked in the Astronaut Office Payloads/Habitability Branch. Clark flew aboard STS-107, logging 15 days, 22 hours and 21 minutes in space.
Space flight experience 
STS-107 Columbia – The 16-day flight was a dedicated science and research mission. Working 24 hours a day, in two alternating shifts, the crew successfully conducted approximately 80 experiments. Clark's bioscience experiments included gardening in space, as she discussed only days before her death in an interview with Milwaukee media near her Wisconsin hometown. The STS-107 mission ended abruptly on February 1, 2003, when Columbia and her crew perished during re-entry, 16 minutes before scheduled landing.
According to the on-board videotape recovered in the debris, Mission Control asked Clark just before her death to perform some small task. She replied that she was currently occupied but would get to it in a minute. "Don't worry about it," she was told. "You have all the time in the world."
