Coleman (left) and Mission Commander Eileen M. Collins (right) check equipment that will fly on mission STS-93. The STS-93 mission will deploy the Advanced X-ray Astrophysics Facility (AXAF) which comprises three major elements: the spacecraft, the telescope, and the science instrument module (SIM). AXAF will allow scientists from around the world to obtain unprecedented X-ray images of a variety of high-energy objects to help understand the structure and evolution of the universe. Collins is the first woman to serve as a shuttle mission commander. The other STS-93 crew members are Pilot Jeffrey S. Ashby, Mission Specialist Steven A. Hawley and Mission Specialist Michel Tognini of France. Targeted date for the launch of STS-93 is March 18, 1999.

Collins smiles on her arrival at KSC's Shuttle Landing Facility aboard a T-38 jet aircraft to participate in Terminal Countdown Demonstration Tests (TCDT) this week. TCDT activities familiarize the crew with the mission, provide training in emergency exit from the orbiter and launch pad, and include a launch-day dress rehearsal culminating with a simulated main engine cut-off. Joining Collins are Pilot Jeffrey S. Ashby and Mission Specialists Steven A. Hawley (Ph.D.), Catherine G. Coleman (Ph.D.) and Michel Tognini of France, with the Centre National d'Etudes Spatiales (CNES). Collins is the first woman to serve as mission commander. The primary mission of STS-93 is the release of the Chandra X-ray Observatory, which will allow scientists from around the world to obtain unprecedented X-ray images of exotic environments in space to help understand the structure and evolution of the universe. Chandra is expected to provide unique and crucial information on the nature of objects ranging from comets in our solar system to quasars at the edge of the observable universe. Since X-rays are absorbed by the Earth's atmosphere, space-based observatories are necessary to study these phenomena and allow scientists to analyze some of the greatest mysteries of the universe.

The primary mission of STS-93 is the release of the Chandra X-ray Observatory, which will allow scientists from around the world to obtain unprecedented X-ray images of exotic environments in space to help understand the structure and evolution of the universe. Chandra is expected to provide unique and crucial information on the nature of objects ranging from comets in our solar system to quasars at the edge of the observable universe.

Hawley (Ph.D.), and Michel Tognini of France, who represents the Centre National d'Etudes Spatiales (CNES). Collins is the first woman to serve as a Shuttle commander. The primary mission of STS-93 is the release of the Chandra X-ray Observatory, which will allow scientists from around the world to obtain unprecedented X-ray images of exotic environments in space to help understand the structure and evolution of the universe. The targeted launch date for STS-93 is no earlier than July 20 at 12:36 a.m. EDT from Launch Pad 39B. Photo Number: KSC-99PP-0762 Photo Title: M.S.

The STS-93 crew numbers five: Commander Eileen M. Collins, Pilot Jeffrey S. Ashby, and Mission Specialists Stephen A. Hawley (Ph.D.), Catherine G. Coleman (Ph.D.) and Tognini. Collins is the first woman to serve as commander of a shuttle mission. STS-93 is scheduled to lift off at 12:36 a.m. EDT July 20. The target landing date is July 24 at 11:30 p.m. EDT.

STS-93 is a five-day mission primarily to release the Chandra X-ray Observatory, which will allow scientists from around the world to study some of the most distant, powerful and dynamic objects in the universe. The crew numbers five: Commander Eileen M. Collins, Pilot Jeffrey S. Ashby, and Mission Specialists Stephen A. Hawley (Ph.D.), Catherine G. Coleman (Ph.D.) and Michel Tognini of France, with the Centre National d'Etudes Spatiales (CNES). Collins is the first woman to serve as commander of a Space Shuttle. The target landing date is July 27, 1999, at 11:20 p.m. EDT.
