STS050-06-011 (25 June-9 July 1992) --- Astronaut Carl J. Meade (left), mission specialist, and Eugene H. Trinh, payload specialist, share a view through one of the Space Shuttle Columbia's aft flight deck windows during a break in photography of Earth. The two were among seven crew members who shared 14 record-setting days aboard the Space Shuttle supporting the United States Microgravity Laboratory (USML-1) mission.

61C-05-036 (12-18 Jan. 1986) --- U.S. Representative Bill Nelson (Democrat - Florida), STS-61C payload specialist, prepares to photograph individual samples in the Handheld Protein Crystal Growth Experiment (HPCG) on Columbia's middeck. The operations involve the use of four pieces of equipment to attempt the growth of 60 different types of crystals -- 12 by means of dialysis and 48 via the vapor diffusion method. The photo was used by members of the STS-61C crew at their Jan. 23, 1986, Post-Flight Press Conference.

S98-08732 (9 April 1998) --- Holding a 35mm camera, U.S. Sen. John H. Glenn Jr. (D.-Ohio) gets a refresher course in photography from a JSC crew trainer (out of frame, right). The STS-95 payload specialist carried a 35mm camera on his historic MA-6 flight over 36 years ago. The photo was taken by Joe McNally, National Geographic, for NASA.

S98-08733 (9 April 1998) --- Looking through the view finder on a camera, U.S. Sen. John H. Glenn Jr. (D.-Ohio) gets a refresher course in photography from a JSC crew trainer (out of frame, right). The STS-95 payload specialist carried a 35mm camera on his historic MA-6 flight over 36 years ago. The photo was taken by Joe McNally, National Geographic, for NASA.

98-E-04388 (8 May 1998) --- U.S. Sen. John H. Glenn Jr. (D.-Ohio) looks at a camera while participating in photography training. Glenn is in Houston training for his assignment as a payload specialist aboard the Space Shuttle Discovery later this year. The Senator is sitting in the hatchway of the full fuselage trainer (FFT) at the Systems Integration Facility at the Johnson Space Center (JSC).

41G-121-139 (5-13 Oct. 1984) --- The Strait of Dover and London, seldom seen in space photography, can be delineated in this medium format camera's scene showing parts of England and France from onboard the Earth-orbiting space shuttle Challenger. Parts of the Thames River can also be traced in the frame. The 41-G crew consisted of astronauts Robert L. Crippen, commander; Jon A. McBride, pilot; and Mission Specialists Kathryn D. Sullivan, Sally K. Ride, and David D. Leestma; along with Canadian astronaut Marc Garneau; and Paul D. Scully-Power, both payload specialists. Photo credit: NASA

S85-46260 (20 Dec. 1985) --- Members of the STS-51L crew designed this patch which will represent their participation on NASA's late January 1986 mission aboard the space shuttle Challenger, depicted launching from Florida and soaring into space to carry out a variety of goals. Among the prescribed duties of the five astronauts and two payload specialists will be observation and photography of Halley's Comet, backdropped against the United States flag in the insignia. Surnames of the crew members encircle the scene, with the payload specialists being recognized below. Surname of the first teacher in space, Sharon Christa McAuliffe, is followed by a symbolic apple. Gregory Jarvis, representing Hughes, is the industrial payload specialist for the flight. NASA's crew members are astronauts Francis R. (Dick) Scobee, commander; Michael J. Smith, pilot; and Ronald E. McNair, Ellison S. Onizuka and Judith A. Resnik - all mission specialists. The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the forms of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, the change will be publicly announced. Photo credit: NASA

STS-85 Payload Specialist Bjarni V. Tryggvason gives a thumbs up as he is assisted with his ascent/reentry flight suit in the Operations and Checkout (O&C) Building. He is a Canadian Space Agency astronaut and was born in Iceland. Tryggvason has also been a flight instructor for the Canadian Air Force. Tryggvason is the principal investigator of the Microgravity Vibration Isolation Mount now flying on the Russian Mir space station. During STS-85, Tryggvason will conduct vibration isolation mount and fluid physics investigations. His work to study how Shuttle vibrations affect the results of experiments will be valuable to the International Space Station program, since this experiment is planned for use on that space platform. Tryggvason will also conduct Bioreactor experiments and assist Mission Specialist Stephen K. Robinson with photography

S84-27219 (3-11 Feb 1984) --- Astronaut Ronald E. McNair, 41-B mission specialist, doubles as "director" for a movie being "produced" aboard the Earth-orbiting Space Shuttle Challenger. McNair’s name tag ("Cecil B. McNair") and beret and slate are all humorous props for application of a serious piece of cargo on this eight day flight - the Cinema 360 camera. Two of the cameras were carried aboard the Challenger to provide a test for motion picture photography in a unique format designed especially for planetarium viewing. This camera was located in the crew cabin area and a second was stowed in a getaway special (GAS) canister in the payload bay. The other camera recorded extravehicular activity (EVA) of the flight’s other two mission specialists, Astronauts Bruce McCandless II and Robert L. Stewart.
