STS-96 STS-103

STS-93 var en flygning i det amerikanska rymdfärjeprogrammet och den tjugosjätte i ordningen för rymdfärjan Columbia. Den sköts upp från Pad 39B vid Kennedy Space Center i Florida den 23 juli 1999. Efter nästan fem dagar i omloppsbana runt jorden återinträdde rymdfärjan i jordens atmosfär och landade vid Kennedy Space Center.

Uppdraget var att placera röntgenteleskopet Chandra i omloppsbana runt jorden. STS-93 var den första rymdfärjeflygningen med en kvinnlig befälhavare.

Uppskjutning

Uppskjutningen var från början planerad till den 20 juli, men avbröts manuellt 7 sekunder före uppskjutning på grund av indikationer på en vätgasläcka.

Under uppskjutningen den 23 juli skadades en av rymdfärjans tre motorer. Detta ledde till att motorn förbrukade mer syre än planerat och alla tre motorerna stannade därför tidigare än planerat. Den slutliga hastigheten blev därmed 4,6 m/s lägre än avsett, men trots detta nådde rymdfärjan den avsedda omloppsbanan och fullföljde expeditionen som planerat.

Under uppskjutningen gjorde även ett elfel att delar av styrsystemen för två av färjans tre raketmotor slogs ut. Men tack vare redundanta system påverkade detta inte uppskjutningen.

Uppskjutningen blev den 21:a nattliga uppskjutningen av en rymdfärja.

Väckningar

Under Geminiprogrammet började NASA spela musik för besättningar och sedan Apollo 15 har man varje "morgon" väckt besättningen med ett musikstycke, särskilt utvalt antingen för en enskild astronaut eller för de förhållanden som råder.

The five astronauts assigned to fly aboard the Space Shuttle Columbia early next year for the STS-93 mission pose with a small model of their primary payload - the Chandra X-ray Observatory (CXO) (then known as the Advanced X-ray Astrophysics Facility (AXAF)). Left-to-right: Eileen M. Collins, mission commander; Steven A. Hawley, mission specialist; Jeffrey S. Ashby, pilot; Michel Tognini, mission specialist; and Catherine G. Coleman, mission specialist. Tognini represents France's Centre National d'Études Spatiales (CNES). The scheduled five-day mission will feature the deployment of AXAF, which will enable scientists to conduct comprehensive studies of exotic phenomena in the universe. Among bodies studied will be exploding stars, quasars, and black holes.
Sts-96-patch.svg
Designed by the crew members, this is the mission insignia for the STS-96 space flight, the second Space Shuttle mission dedicated to the assembly of the International Space Station (ISS). The crew patch highlights the major themes of the Station Program: Earth-directed research, the advancement of human space exploration, and international cooperation. The Space Shuttle Discovery is depicted shortly after reaching orbit as the crew prepares to carry out the first docking with the new Station. At this early stage in its construction, ISS consists of two modules: Zarya and Unity, shown orbiting Earth. The triangular shape of the patch represents building on the knowledge and experience of earlier missions, while the three vertical bars of the astronaut emblem point toward future human endeavors in space. The five-pointed star that tops the astronaut emblem in this depiction is symbolic of the five space agencies participating in the development of ISS: NASA, the Russian Space Agency, the European Space Agency, the National Space Development Agency of Japan, and the Canadian Space Agency. The blend of red, white, and blue is a tribute to the nationalities of the crew members who are from the United States, Canada, and Russia.

STS093 (S)-001 (Sept. 1998) --- The STS-93 mission patch, as designed by the five crew members. The STS-93 mission 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 and the Compton Gamma Ray Observatory. AXAF will provide scientists an order-of-magnitude improvement over current capabilities at X-ray wavelengths. 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 STS-93 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 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 form of illustrations by the various news media. When and if there is any change in this policy, which we do not anticipate, it will be publicly announced.
STS-103 Patch.svg
Designed by the crewmembers, the STS-103 emblem depicts the Space Shuttle Discovery approaching the Hubble Space Telescope (HST) prior to its capture and berthing. The purpose of the mission is to remove and replace some of the Telescope's older and out-of-date systems with newer, more reliable and more capable ones, and to make repairs to HST's exterior thermal insulation that has been damaged by more than nine years of exposure to the space environment. The horizontal and vertical lines centered on the Telescope symbolize the ability to reach and maintain a desired attitude in space, essential to the instrument's scientific operation. The preservation of this ability is one of the primary objectives of the mission. After the flight, the Telescope will resume its successful exploration of deep space and will continue to be used to study solar system objects, stars in the making, late phases of stellar evolution, galaxies and the early history of the universe. HST, as represented on this emblem was inspired by views from previous servicing missions, with its solar arrays illuminated by the Sun, providing a striking contrast with the blackness of space and the night side of Earth.
