The Space Shuttle Atlantis in full launch configuration is reflected in water around Launch Pad 39A as the Rotating Service Structure (RSS) is rotated back to the park position. Rollback of the RSS is a major preflight milestone, typically occurring during the T-11-hour hold on L-1 (the day before launch). Atlantis and its crew of seven are in final preparations for liftoff on Mission STS-84, the sixth of nine planned dockings of the Space Shuttle with the Russian Space Station Mir. Launch is scheduled at about 4:08 a.m. during an approximately 7-minute launch window. The exact liftoff time will be determined about 90 minutes prior to launch, based on the most current location of Mir
jsc2024e043737 (4/17/2024) --- A scanning electron-microscopy image of human platelets taken preflight at the NASA Space Radiation Laboratory. Megakaryocytes Orbiting in Outer Space and Near Earth: The MOON Study (Megakaryocyte Flying-One (MeF1)) investigates how environmental conditions affect development and function of platelets and megakaryocytes, cells found in bone marrow. Results could clarify the risks of changes in inflammation, immune responses, and clot formation in spaceflight and on the ground. Platelets are isolated from NASA crew members before they launch to the International Space Station, and after return to Earth. Image courtesy of the NASA Space Radiation Laboratory.
After addressing the media at the Shuttle Landing Facility, the STS-99 crew wave goodbye as they leave for crew quarters in the Operations and Checkout Building. The crew is ready to prepare for the second launch attempt of Endeavour Feb. 11 at 12:30 p.m. EST from Launch Pad 39A. The earlier launch scheduled for Jan. 31 was scrubbed due to poor weather and a faulty Enhanced Master Events Controller in the orbiter's aft compartment. Over the next few days, the crew will review mission procedures, conduct test flights in the Shuttle Training Aircraft and undergo routine preflight medical exams. STS-99 is the Shuttle Radar Topography Mission, which will produce unrivaled 3-D images of the Earth's surface. The result of the Shuttle Radar Topography Mission could be close to 1 trillion measurements of the Earth's topography. Landing is expected at KSC on Feb. 22 at 4:36 p.m. EST
