S91-46260 (1991) --- Astronaut Eugene H. Trinh, STS-50 USML payload specialist.

The STS-50 crew portrait includes (from left to right): Ellen S. Baker, mission specialist; Kenneth D. Bowersox, pilot; Bonnie J. Dunbar, payload commander; Richard N. Richards, commander; Carl J. Meade, mission specialist; Eugene H. Trinh, payload specialist; and Lawrence J. DeLucas, payload specialist. Launched aboard the Space Shuttle Columbia on June 25, 1992 at 12:12:23 pm (EDT), the primary payload for the mission was the U.S. Microgravity Laboratory-1 (USML-1) featuring a pressurized Spacelab module.

In this photograph, astronaut Eugene Trinh, a payload specialist for this mission, is working at the Drop Physics Module (DPM), and mission specialist Carl Meade is working on the experiment at the Glovebox inside the first United States Microgravity Laboratory (USML-1) Science Module. The USML-1 was one of NASA's missions dedicated to scientific investigations in a microgravity environment inside the Spacelab module. Investigations aboard the USML-1 included: materials science, fluid dynamics, biotechnology (crystal growth), and combustion science. The DPM is dedicated to the detailed study of the dynamics of fluid drops in microgravity. The Glovebox offers experimenters new capabilities and technologies in microgravity with a clean working space and minimizes contamination risks to both Spacelab and experiment samples. Payload specialists are professional scientists or engineers whose only assignment on a space flight is to carry out scientific and technological experiments. Their specific training for a space flight is usually limited to a short period of learning how to live and work in weightlessness. Mission Specialists are both professional scientists and career astronauts. Thus they are a link or bridge between the other crew members, and combine the functions of resident maintenance engineers, in-space counterparts of flight engineers in aircraft, and fully qualified scientists. The USML-1 flew aboard the STS-50 mission on June 1992, and was managed by the Marshall Space Flight Center.

STS050-255-027 (25 June-9 July 1992) --- Payload specialist Eugene H. Trinh, left, and astronaut Carl J. Meade, mission specialist, go to work in the U.S. Microgravity Laboratory (USML-1) science module as the blue shift crew takes over from the red. Trinh is working with an experiment at the Drop Physics Module (DPM) and Meade prepares to monitor an experiment in the Glovebox. The two joined four other astronauts and a second scientist from the private sector for 14-days of scientific data-gathering.

STS050-301-001 (25 June-9July 1992) --- Astronaut Carl J. Meade, mission specialist, works with the Generic Bioprocessing Apparatus in the science module aboard the Earth-orbiting Space Shuttle Columbia. Payload specialist Eugene H. Trinh is partially visible (left), monitoring an experiment in the Drop Physics Module (DPM). The two joined four other astronauts and a second scientist from the private sector for 14-days of scientific data-gathering.

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.

STS050-S-002 (24 Jan. 1992) --- The seven crew members assigned to NASA's mission pose for the traditional crew portrait. The crew was in Palmdale, California for the Space Shuttle Columbia's Extended-Duration Orbiter (EDO) modifications roll-out. Astronaut Richard N. Richards, mission commander, is center. Astronaut Kenneth D. Bowersox, pilot, is second from left. Others, left to right, are astronauts Ellen S. Baker, mission specialist; Bonnie J. Dunbar, payload commander; and Carl J. Meade, mission specialist; Eugene H. Trinh and Lawrence J. DeLucas, payload specialists.
