STS-65 Mission Specialist (MS) Leroy Chiao (top) and MS Donald A. Thomas are seen at work in the International Microgravity Laboratory 2 (IML-2) spacelab science module aboard the Space Shuttle Columbia, Orbiter Vehicle (OV) 102. The two crewmembers are conducting experiments at the IML-2 Rack 5 Biorack (BR). Chiao places a sample in the BR incubator as Thomas handles another sample inside the BR glovebox. The glovebox is used to prepare samples for BR and slow rotating centrifuge microscope (NIZEMI) experiments.

STS034-09-007 (23 Oct. 1989) --- Having been in space only a few hours, three of the STS-34 astronaut crew prepare for pre-deployment exercises involving one of the most prominent "passengers" of the flight -- the Galileo payload which was lying in Atlantis', Orbiter Vehicle (OV) 104's, payload bay (PLB). Pictured, left to right, are astronauts Ellen S. Baker and Shannon W. Lucid, both mission specialists; along with Donald E. Williams, commander, who guided OV-104's course during the exercise. Baker and Lucid communicated with ground controllers while juggling other Galileo-related chores. Both Baker and Lucid are equipped with SONY Walkmans and are wearing headsets. Lucid wears a pair of sunglasses with brightly colored frames. A tethered inertial upper stage (IUS) deploy checklist (C/L) floats between the two and a spotmeter is Velcroed to an on orbit station control panel.

STS035-10-005 (2-10 Dec 1990) --- STS-35 Mission Specialist (MS) Jeffrey A. Hoffman (front) and Pilot Guy S. Gardner, holding Development Test Objective (DTO) 634 trash compactor handles to the ceiling, "commute" to work on the middeck of Columbia, Orbiter Vehicle (OV) 102. Just below Hoffman's right elbow in locker MF43G DTO 634, Trash Compaction and Retention System Demonstration, trash compactor with a geared mechanism that allows manual compaction of wet and dry trash is visible. Also in the view are the stowed treadmill on the middeck floor and the starboard side sleep station.

STS044-32-030 (24 Nov-1 Dec 1991) --- STS-44 Commander Frederick D. Gregory wears a cap honoring his alma mater, the United States Air Force (USAF) Academy, on the middeck of Atlantis, Orbiter Vehicle (OV) 104. Gregory, who also has his lightweight headset on, was photographed while talking to ground controllers.

STS035-15-010 (2-11 Dec 1990) --- Astronaut John M. (Mike) Lounge, STS-35 mission specialist, communicates with family members from the middeck of Space Shuttle Columbia in Earth orbit.  The STS-35 Shuttle amateur radio experiment (SAREX), allowed the Astro 1 crewmembers to "visit" and briefly share some of their in space experiences with family members.  The picture was made with a 35mm camera.                           Note: Used by Astronomer Ronald A. Parise on his off-duty hours,  SAREX provided radio transmissions between ground based amateur radio operators around the world and the Shuttle. Parise is a payload specialist who is also a licensed amateur radio operator (call-sign WA4SIR).  The experiment enabled students from all over the United States to have a chance to communicate with an astronaut in space.

STS-36 Commander John O. Creighton, smiling and wearing a headset, listens to music as the tape recorder freefloats in front of him. During this lighter moment of the mission, Creighton is positioned at the commanders station on the forward flight deck of Atlantis, Orbiter Vehicle (OV) 104. Forward flight deck windows W1 and W2 appear on his left. Creighton and four other astronauts spent four days, 10 hours and 19 minutes aboard the spacecraft for the Department of Defense (DOD) devoted mission.

STS044-32-003 (24 Nov.-1 Dec. 1991) --- Astronaut F. Story Musgrave, STS-44 mission specialist, makes visual observations through Atlantis' hatch window. This photograph was among the first released by NASA following the eight day mission, dedicated to the Department of Defense.

STS047-37-003 (12-20 Sept. 1992) --- Astronaut Mae C. Jemison, STS-47 mission specialist, appears to be clicking her heels in zero-gravity in this 35mm frame photographed in the Science Module aboard the Earth-orbiting Space Shuttle Endeavour. Making her first flight in space, Dr. Jemison was joined by five other NASA astronauts and a Japanese payload specialist for eight days of research in support of the Spacelab-J mission, a joint effort between Japan and the United States.

STS047-03-024 (12 - 20 Sept 1992) --- Astronaut N. Jan Davis, mission specialist, talks to ground controllers as she works with the Free Flow Electrophoresis Unit (FFEU) in the Science Module of the Earth-orbiting Space Shuttle Endeavour.  Davis joined five other NASA astronauts and a Japanese payload specialist for eight days of scientific research onboard Endeavour.

STS60-29-009 (10 Feb 1994) --- On the Space Shuttle Discovery's aft flight deck, Russian cosmonaut Sergei K. Krikalev prepares for one chore while performing another.  Using the Shuttle Amateur Radio Experiment (SAREX) gear, the mission specialist was talking with students in Maine.  He holds a camcorder, which was later called into action to record inflight activities.  Krikalev joined five NASA astronauts for eight days in space aboard Discovery.

STS055-203-034 (26 April-6 May 1993) --- Astronaut Steven R. Nagel, STS-55 mission commander, has found an isolated station in the D-2 science module from which to talk to students on Earth.  Like many before it, the seven member crew participated in communications with students and licensed radio operators via the Shuttle Amateur Radio Experiment (SAREX). Photo credit: NASA

STS035-12-015 (2-11 Dec 1990) --- Astronaut Jeffrey A. Hoffman, STS 35 mission specialist, uses a manual pointing controller (MPC) for the Astro-1 mission's Instrument Pointing System (IPS).   By using the MPC,  Hoffman and other crewmembers on Columbia's aft flight deck,  were able to command the IPS, located in the cargo bay, to record astronomical data.  Hoffman is serving the "Blue" shift which complemented the currently sleeping "Red" shift of crewmembers as the mission collected scientific data on a 24-hour basis.  The scene was photographed with a 35mm camera.

STS-35 Payload Specialist Ronald A. Parise enters data into the payload and general support computer (PGSC) in preparation for Earth communication via the Shuttle Amateur Radio Experiment (SAREX) aboard Columbia, Orbiter Vehicle (OV) 102. The SAREX equipment is secured to the middeck starboard sleep station. SAREX provided radio transmissions between ground based amateur radio operators around the world and Parise, a licensed amateur radio operator. The experiment enabled students to communicate with an astronaut in space, as Parise (call-sign WA4SIR) devoted some of his off-duty time to that purpose. Displayed on the forward lockers beside Parise is a AMSAT (Amateur Radio Satellite Corporation) / ARRL (American Radio Relay League) banner. Food items and checklists are attached to the lockers. In locker position MF43G, the Development Test Objective (DTO) Trash Compaction and Retention System Demonstration extended duration orbiter (EDO) compactor is visible.
