In the Orbiter Processing Facility Bay 3, during the Crew Equipment Interface Test (CEIT), Mission Specialist Catherine G. 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 KSC-98pc1687

KENNEDY SPACE CENTER, FLA. -- The orbiter Columbia, aboard its orbiter transporter system, makes the turn from the Orbiter Processing Facility (behind it, left) to the nearby Vehicle Assembly Building (VAB) for external tank mating operations. Columbia is scheduled for rollout to Launch Pad 39B on Monday, June 7, for mission STS-93. The primary mission objective will be the deployment of the Advanced X-ray Astrophysics Facility, recently renamed the Chandra X-Ray Observatory. Mission STS-93 will be the first Space Shuttle commanded by a woman, Commander Eileen M. Collins. It is scheduled to launch July 22 at 12:27 a.m. EDT although that date is currently under review KSC-99pp0614

VANDENBERG AIR FORCE BASE, CALIF. -- Inside a clean room at Vandenberg Air Force Base in California, workers stand beside NASA's Aeronomy of Ice in the Mesosphere, or AIM, spacecraft, waiting for an overhead crane. AIM is the seventh Small Explorers mission under NASA's Explorer Program. The program provides frequent flight opportunities for world-class scientific investigations from space within heliophysics and astrophysics. The AIM spacecraft will fly three instruments designed to study polar mesospheric clouds located at the edge of space, 50 miles above the Earth's surface in the coldest part of the planet's atmosphere. The mission's primary goal is to explain why these clouds form and what has caused them to become brighter and more numerous and appear at lower latitudes in recent years. AIM's results will provide the basis for the study of long-term variability in the mesospheric climate and its relationship to global climate change. AIM is scheduled to be mated to the Pegasus XL during the second week of April, after which final inspections will be conducted. Launch is scheduled for April 25. KSC-07pd0674

A massive 19 million pounds-plus (8.6 million kilograms) of Space Shuttle, support and transport hardware inch toward Launch Pad 39A from the Vehicle Assembly Building. The fully asssembled Space Shuttle Endeavour, minus its payloads, weighs about 4.5 million pounds (2 million kg.); the mobile launcher platform, on which it was assembled and from which it will lift off, weighs 9.25 million pounds (4.19 million kg.); and the crawler-transporter carrying the platform and Shuttle checks in at around 6 million pounds (2.7 million kg.). Once at the pad, the Shuttle and launch platform will be deposited atop support columns to complete preparations for the second Shuttle launch of 1995. The primary payload of mission STS-67 is the Astro-2 Astrophysics Observatory, carrying three ultraviolet telescopes that flew on the Astro-1 mission in 1990. STS-67 also is scheduled to become the longest shuttle flight to date, lasting 16 days KSC-95PC-0289

The STS-91 payload arrived at KSC in January and is scheduled to be flown on the 9th and final Mir docking mission, scheduled for launch in May. The objectives of the AMS-1 investigation are to search for anti-matter and dark matter in space and to study astrophysics. The STS-91 flight crew includes Commander Charles Precourt; Pilot Dominic Gorie; and Mission Specialists Wendy B. Lawrence; Franklin Chang-Diaz, Ph.D.; Janet Kavandi, Ph.D.; and Valery Ryumin, with the Russian Space Agency. After docking with the Russian Space Station Mir, Mission Specialist Andrew Thomas, Ph.D., will join the STS-91 crew and return to Earth aboard Discovery KSC-147fr11

STS093-S-001 (September 1998) --- This is the STS-93 mission insignia designed by the crew members. Space shuttle Columbia will carry the Advanced X-ray Astrophysics Facility (AXAF) into low Earth orbit initiating its planned five-year astronomy mission. AXAF is the third of NASA's great observatories, following the Hubble Space Telescope (HST) and the Compton Gamma Ray Observatory (GRO). AXAF will provide scientists and order-of magnitude improvement over current capabilities at X-ray wavelengths. In the words of the crew, "Observations of X-ray emissions from energetic galaxies and clusters, as well as black holes, promise to greatly expand current understanding of the origin and evolution of our universe." The patch depicts AXAF separating from the space shuttle Columbia after a successful deployment. A spiral galaxy is shown in the background as a possible target for AXAF observations. The two flags represent the international crew, consisting of astronauts from both the United States and France. The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the forms of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, the change will be publicly announced. Photo credit: NASA sts093-s-001

VANDENBERG AIR FORCE BASE, CALIF. -- At Vandenberg Air Force Base in California, the three stages of the Orbital Sciences Pegasus XL are being mated for the launch of NASA's Aeronomy of Ice in the Mesosphere, or AIM, spacecraft. AIM is the seventh Small Explorers mission under NASA's Explorer Program. The program provides frequent flight opportunities for world-class scientific investigations from space within heliophysics and astrophysics. The AIM spacecraft will fly three instruments designed to study polar mesospheric clouds located at the edge of space, 50 miles above the Earth's surface in the coldest part of the planet's atmosphere. The mission's primary goal is to explain why these clouds form and what has caused them to become brighter and more numerous and appear at lower latitudes in recent years. AIM's results will provide the basis for the study of long-term variability in the mesospheric climate and its relationship to global climate change. AIM is scheduled to be mated to the Pegasus XL during the second week of April, after which final inspections will be conducted. Launch is scheduled for April 25. KSC-07pd0650

KENNEDY SPACE CENTER, FLA. -- The alpha-magnetic spectrometer (AMS-1) is lifted in KSC’s MultiPayload Processing Facility in preparation for a move to the Space Station Processing Facility via the Payload Environmental Transportation System. The STS-91 payload arrived at KSC in January and is scheduled to be flown on the 9th and final Mir docking mission, scheduled for launch in May. The objectives of the AMS-1 investigation are to search for anti-matter and dark matter in space and to study astrophysics. The STS-91 flight crew includes Commander Charles Precourt; Pilot Dominic Gorie; and Mission Specialists Wendy B. Lawrence; Franklin Chang-Diaz, Ph.D.; Janet Kavandi, Ph.D.; and Valery Ryumin, with the Russian Space Agency. After docking with the Russian Space Station Mir, Mission Specialist Andrew Thomas, Ph.D., will join the STS-91 crew and return to Earth aboard Discovery KSC-98pc375

In the Orbiter Processing Facility Bay 3, aboard the orbiter Columbia, STS-93 Mission Commander Eileen M. Collins listens to Mission Specialist Steven A. Hawley during the Crew Equipment Interface Test (CEIT). Collins is the first woman to serve as a mission commander on a shuttle flight. The CEIT provides an opportunity for crew members to check equipment and facilities that will be aboard the orbiter during their mission. The rest of the crew members are Pilot Jeffrey S. Ashby, Mission Specialist Catherine G. Coleman, and Mission Specialist Michel Tognini of France. 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. Targeted date for the launch of STS-93 is March 18, 1999 KSC-98pc1693
