NASA research pilot Jim Less wears a U.S. Navy harness configuration with the NASA Jet Propulsion Laboratory in California prototype mask, which uses laser sensors to determine levels of carbon dioxide and water exhaled inside the mask. This prototype was tested in conjunction with the current VigilOX system, which measures the pilot’s oxygen concentration, breathing pressures and flow rates. This and the U.S. Air Force configuration was used in the Pilot Breathing Assessment program at NASA’s Armstrong Flight Research Center in California.

NASA Pilot Nils Larson wears a U.S. Navy harness configuration to show the integrated parachute harness and the built-in survival vest. The Navy configuration is bulkier and weighs more than the U.S. Air Force harness. Both configurations are being used in the Pilot Breathing Assessment program at NASA’s Armstrong Flight Research Center in California.

KENNEDY SPACE CENTER, FLA. - After Discovery's safe landing on Runway 15 at NASA's Shuttle Landing Facility, safety assessment teams dressed in protective attire and with breathing apparatus obtain vapor level readings around the orbiter and test for possible explosive or toxic gases such as hydrogen, hydrazine, monomethyl-hydrazine, nitrogen tetroxide or ammonia . Completing mission STS-121 to the International Space Station, Discovery traveled 5.3 million miles, landing on orbit 202. Mission elapsed time was 12 days, 18 hours, 37 minutes and 54 seconds. Main gear touchdown occurred on time at 9:14:43 EDT. Wheel stop was at 9:15:49 EDT. The returning crew members are Commander Steven Lindsey, Pilot Mark Kelly and Mission Specialists Piers Sellers, Michael Fossum, Lisa Nowak and Stephanie Wilson. Mission Specialist Thomas Reiter, who launched with the crew on July 4, remained on the station to join the Expedition 13 crew there. The landing is the 62nd at Kennedy Space Center and the 32nd for Discovery. Discovery's landing was as exhilarating as its launch, the first to take place on America's Independence Day. During the mission, the STS-121 crew tested new equipment and procedures to improve shuttle safety, and delivered supplies and made repairs to the International Space Station.
