 | S93-E-5057 (24 July 1999) --- Astronaut Eileen M. Collins, mission commander, enters notes on a log at the commander's station on Columbia's flight deck. A small cluster of clouds can be seen over ocean waters out the port window. Collins is joined by four crew mates for the almost five-day mission in Earth orbit. The photo was recorded with an electronic still camera (ESC). |
 | S93-E-5058 (24 July 1999) --- Astronaut Catherine G. (Cady) Coleman, mission specialist, moves through the passageway between Columbia's middeck and flight deck. This picture was taken with an electronic still camera (ESC). |
 | S93-E-5067 (23 July 1999)--- Astronaut Steven A. Hawley, mission specialist, removes stowed hardware in preparation for deploying the Treadmill Vibration Isolation System (TVIS) on Columbia's middeck. The photo was taken with an electronic still camera (ESC). |
 | S93-E-5069 (24 July 1999) --- Astronaut Eileen M. Collins, mission commander, checks the status of one of the middeck experiments carried on Columbia for STS-93. The experiment is called the Cell Culture Model, Configuration C. Objectives of it are to validate cell culture models for muscle, bone and endothelial cell biochemical and functional loss induced by microgravity stress; to evaluate cytoskeleton, metabolism, membrane integrity and protease activity in target cells; and to test tissue loss pharmaceuticals for efficacy. The photo was recorded with an electronic still camera (ESC). |
 | S93-E-5082 (25 July 1999) --- Astronauts Michel Tognini(left), mission specialist, and Jeffrey S. Ashby, pilot, unstow some of the hardware for the Treadmill Vibration Isolation System (TVIS) as they prepare to deploy it on Columbia's middeck. The photo was recorded with an electronic still camera (ESC). |
 | S93-E-5087 (24 July 1999) --- Astronauts Catherine G. (Cady) Coleman, and Michel Tognini look at the lightweight flexible solar array hinge (LFSAH) on Columbia's middeck. LFSAH consists of several hinges fabricated from shape-memory alloys, which allow controlled, shockless deployment of solar arrays and other spacecraft appendages. The LFSAH is expected to demonstrate the deployment capability of a number of hinge configurations during the flight. Hinges are the primary mechanism used to deploy spacecraft solar arrays, which are folded and stowed for launch. The photo was recorded with an electronic still camera (ESC) on Flight Day 3. |
 | S93-E-5088 (24 July 1999) --- Astronauts Steven A. Hawley (left) and Michel Tognini are pictured with the Southwest Ultraviolet Imaging System (SWUIS) on Columbia's middeck. SWUIS is an innovative telescope/charge-coupled device (CCD) camera system that operates from inside the shuttle cabin. SWUIS will be used during the STS-93 mission to image planets and other solar system bodies in order to explore their atmospheres and surfaces in ultraviolet (UV) region of the spectrum, which astronomers value for diagnostic value. The photo was recorded with an electronic still camera (ESC) on Flight Day 2. |
 | S93-E-5095 (25 July 1999) --- Astronaut Steven A. Hawley, mission specialist, runs on a treadmill as part of a test with the Treadmill Vibration Isolation System (TVIS) on Columbia's middeck. He is monitored in the experiment by astronaut Michel Tognini (background), mission specialist. The photo was taken with an electronic still camera (ESC). |
 | S93-E-5105 (25 July 1999) --- A closeup view of a few of the 36 mouse-ear cress plants (arabidopsis thaliana) being observed and studied by the STS-93 crew was provided with an electronic still camera (ESC) on Flight Day 3. The plants are part of the Plant Growth Investigations in Microgravity 1 (PGIM-1) experiment onboard Columbia. |
 | S93-E-5116 (25 July 1999) --- Astronaut Jeffrey S. Ashby, pilot, runs on a treadmill as part of a test with the Treadmill Vibration Isolation System (TVIS) on Columbia's middeck. The photo was taken with an electronic still camera (ESC). |
