 | S93-E-5003 (23 July 1999) --- Astronaut Jeffrey S. Ashby, pilot, works at the Space Tissue Loss-B experiment on Space Shuttle Columbia's middeck. The experiment is set up to observe cells in culture with a video microscope imaging system to record near-real-time interactions of detecting and inducing cellular responses (macromorphological changes). Just above and to the right of STL-B is the part of the Commercial Generic Bioprocessing Apparatus (CGBA) for the National Institute of Health (NIH-B experiment). It is an experiment designed to investigate the effects of space flight on neural development in Drosophila melanogaster (fruit fly) larvae. This information may help scientists understand how gravity affects nerve growth and development and how neural connections to muscle fibers work. The photo was recorded with an electronic still camera (ESC) on Flight Day 1. Ashby and his four crew mates are scheduled to spend five days aboard Columbia in Earth orbit. |
 | S93-E-5006 (23 July 1999) --- Astronaut Michel Tognini, mission specialist representing the French space agency (CNES), opens the gaseous nitrogen (GN2) freezer on Columbia's middeck. The freezer is flown in support of two plant growth experiments--Plant Growth Investigations in Microgravity (PGIM) and Biological Research in Canisters (BRIC). Throughout the mission Tognini periodically freezes samples from the experiments to provide glimpses of the plants in various stages of development. The photo was recorded with an electronic still camera (ESC) on Flight Day 1. |
 | S93-E-5011 (23 July 1999) --- Astronaut Steven A. Hawley, mission specialist, looks over a checklist on Columbia's middeck during Flight Day 1 activity. The image was recorded with an electronic still camera (ESC). |
 | S93-E-5016 (23 July 1999) --- Astronaut Eileen M. Collins, mission commander, checks on an experiment on Columbia's middeck during Flight Day 1 activity. 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-5026 (23 July 1999) --- Astronaut Catherine G. (Cady) Coleman works with a small plant seedling on Columbia's flight deck. The photo was recorded with an electronic still camera (ESC) on Flight Day 1. |
 | 93-E-5033 (23 July 1999) --- Astronaut Eileen M. Collins, mission commander, looks over a procedures checklist at the commander's station on the forward flight deck of the Space Shuttle Columbia on Flight Day 1. The most important event of this day was the deployment of the Chandra X-Ray Observatory, the world's most powerful X-Ray telescope. The photo was recorded with an electronic still camera (ESC). |
 | S93-E-5043 (24 July 1999) --- Astronaut Catherine G. (Cady) Coleman, mission specialist, checks the support system for the Plant Growth Investigations in Microgravity 1 (PGIM-1) experiment on Columbia's middeck. The photo was recorded with an electronic still camera (ESC) on Flight Day 2. |
 | S93-E-5050 (24 July 1999) --- Astronaut Steven A. Hawley, mission specialist, is pictured with the Micro-Electromechanical Systems (MEMS) experiment on Columbia's middeck. MEMS examines the performance of a suite of devices under launch, microgravity and reentry conditions. These devices include accelerometers, gyros and environmental and chemical sensors. The MEMS payload is self-contained and requires crew interface for activation and deactivation only. |
 | S93-E-5052 (24 July 1999) --- Astronaut Michel Tognini, mission specialist, uses the Shuttle Amateur Radio Experiment II (SAREX-II) on Columbia's flight deck. SAREX was designed to demonstrate the feasibility of contact between the shuttle and ground-based amateur operators, often called "hams."; SAREX also serves as an educational tool, allowing school children around the world to learn about space firsthand by speaking directly to astronauts aboard the shuttle. SAREX has flown on 19 previous shuttle missions. |
 | S93-E-5055 (24 July 1999) --- Astronaut Eileen M. Collins, mission commander, aims a camera through the overhead windows of the Space Shuttle Columbia. Collins and her crew earlier had released the Chandra X-Ray Observatory into space. The five astronauts are scheduled to spend a little less than five days in Earth orbit. This image was recorded with an electronic still camera (ESC). |
