In the Operations and Checkout Building, STS-101 Mission Specialist Susan J. Helms (left) and a suit technician grin with anticipation for a successful second attempt at launch of Space Shuttle Atlantis on mission STS-101. The previous day's launch attempt was scrubbed due to high cross winds at the Shuttle Landing Facility. The mission will take the crew to the International Space Station to deliver logistics and supplies and to prepare the Station for the arrival of the Zvezda Service Module, expected to be launched by Russia in July 2000. Also, the crew will conduct one space walk. This will be the third assembly flight to the Space Station. Liftoff is targeted for 3:52 p.m. EDT. The mission is expected to last about 10 days, with Atlantis landing at KSC Saturday, May 6, about 11:53 a.m. EDT

KENNEDY SPACE CENTER, FLA. -- Billows of white clouds of steam and smoke frame Space Shuttle Columbia as it rises above the launch tower on Launch Pad 39A on mission STS-107. Following a flawless and uneventful countdown, liftoff occurred on-time at 10:39 a.m. EST. The 16-day research mission will include FREESTAR (Fast Reaction Experiments Enabling Science, Technology, Applications and Research) and the SHI Research Double Module (SHI/RDM), known as SPACEHAB. Experiments on the module range from material sciences to life sciences. Landing is scheduled at about 8:53 a.m. EST on Saturday, Feb. 1. This mission is the first Shuttle mission of 2003. Mission STS-107 is the 28th flight of the orbiter Columbia and the 113th flight overall in NASA's Space Shuttle program.

In the Operations and Checkout Building, STS-101 Commander James D. Halsell Jr. gets final check on his launch and entry suit before heading a second time to Launch Pad 39A and launch of Space Shuttle Atlantis. The previous day's launch attempt was scrubbed due to high cross winds at the Shuttle Landing Facility. The mission will take the crew to the International Space Station to deliver logistics and supplies and to prepare the Station for the arrival of the Zvezda Service Module, expected to be launched by Russia in July 2000. Also, the crew will conduct one space walk. This will be the third assembly flight to the Space Station. Liftoff is targeted for 3:52 p.m. EDT. The mission is expected to last about 10 days, with Atlantis landing at KSC Saturday, May 6, about 11:53 a.m. EDT

Waving to onlookers, the STS-101 crew eagerly walk to the waiting Astrovan that will take them to Launch Pad 39A and the second attempt at liftoff of Space Shuttle Atlantis. In their orange launch and entry suits, they are (left to right) Mission Specialists Susan J. Helms, Yury Usachev, James S. Voss, Mary Ellen Weber and Jeffrey N. Williams; Pilot Scott J. Horowitz; and Commander James D. Halsell Jr. The first launch attempt on April 24 was scrubbed due to unfavorable weather conditions. The mission will take the crew to the International Space Station to deliver logistics and supplies and to prepare the Station for the arrival of the Zvezda Service Module, expected to be launched by Russia in July 2000. Also, the crew will conduct one space walk. This will be the third assembly flight to the Space Station. Liftoff is targeted for 3:52 p.m. EDT. The mission is expected to last about 10 days, with Atlantis landing at KSC Saturday, May 6, about 11:53 a.m. EDT

KENNEDY SPACE CENTER, FLA. -- Space Shuttle Columbia soars into the cloud-washed sky above Cape Canaveral Lighthouse. After six scrubs from the original Sept. 25 launch date, liftoff occurred Oct. 20 at 9:53 a.m. EDT. The crew of seven comprises Commander Ken Bowersox, Pilot Kent Rominger, Mission Specialists Kathy Thornton (Payload Commander), Catherine Coleman and Michael Lopez-Alegria, plus Payload Specialists Fred Leslie and Albert Sacco. The 72nd Shuttle mission, STS-73 marks the second flight of the U.S. Microgravity Laboratory. Research is being conducted in five areas: fluid physics, materials science, biotechnology, combustion science, and commercial space processing. The lighthouse, undergoing refurbishment and upgrade, is shown with a network of nylon lines ready for canvas panels to be attached. The canvas shroud will protect the surrounding area during sand-blasting of the lead-based paint.
