The Technology Applications and Science-1  (TAS-1) payload for the STS-85 mission rests in a payload canister in the Space Station  Processing Facility prior to its trip out to Launch Pad 39A for installation into the payload  bay of the Space Shuttle Orbiter Discovery. The TAS-1 holds seven separate experiments  that will provide data on the Earth’s topography and atmosphere, study the sun’s energy,  and test new thermal control devices, as well as several student-developed experiments.  Other STS-85 payloads include the Cryogenic Infrared Spectrometers and Telescopes for  the Atmosphere-Shuttle Pallet Satellite-2 (CRISTA-SPAS-2). The CRISTA is a system of  three telescopes and four spectrometers to measure infrared radiation emitted by the  Earth’s middle atmosphere. During the 11-day mission, the CRISTA-SPAS-2 free-flying  satellite will be deployed from Discovery and retrieved later in the flight. Also onboard  the satellite will be the Middle Atmosphere High Resolution Spectrograph Investigation  (MAHRSI) to measure ultraviolet radiation emitted and scattered by the Earth’s  atmosphere. The International Extreme Ultraviolet Hitchhiker-2 (IEH-2) will also be in  the payload bay. The IEH-2 experiments will study ultraviolet radiation from stars, the  sun and in the solar system KSC-97PC1008

STS-90 Mission Specialist Dafydd "Dave" Rhys Williams, M.D., with the Canadian Space Agency, and back-up Payload Specialist Chiaki Mukai, M.D., Ph.D., with the National Space Development Agency of Japan, examine items to be used during the Crew Equipment Interface Test (CEIT) in Kennedy Space Center's (KSC's) Operations and Checkout Building, where the Neurolab payload is undergoing processing. The CEIT gives astronauts an opportunity to get a hands-on look at the payloads with which they will be working on-orbit. STS-90 is scheduled to launch aboard the Shuttle Columbia from KSC on April 2. Investigations during the Neurolab mission will focus on the effects of microgravity on the nervous system. Specifically, experiments will study the adaptation of the vestibular system, the central nervous system, and the pathways that control the ability to sense location in the absence of gravity, as well as the effect of microgravity on a developing nervous system KSC-98pc146

KENNEDY SPACE CENTER, Fla. -- Resting inside Atlantis’s payload bay are the Joint Airlock Module (bottom) and pallet containing the high pressure gas assembly (above). Both are heading for the International Space Station on mission STS-104, scheduled to be launched July 12. The module, which comprises a crew lock and an equipment lock, will be connected to the starboard (right) side of Node 1 Unity. Once installed and activated, the Airlock becomes the primary path for Space Station spacewalk entry and departure for U.S. spacesuits, which are known as Extravehicular Mobility Units, or EMUs. In addition, the Joint Airlock is designed to support the Russian Orlan spacesuit for EVA activity.

KENNEDY SPACE CENTER, Fla. -- More than a dozen photographers line up to photograph the Genesis-Delta launch vehicle after rollback of the Mobile Service Tower (right) on Launch Complex 17-A, Cape Canaveral Air Force Station. The Genesis launch is scheduled for Aug. 1, 2001, from CCAFS.; however, a gray overcast sky forecasts a questionable launch effort due to weather conditions. Genesis will be on a robotic NASA space mission to collect just 10 to 20 micrograms -- or the weight of a few grains of salt -- of solar wind, invisible charged particles that flow outward from the Sun -- and return them to Earth. This treasured smidgen of the Sun will be preserved in a special laboratory for study by scientists over the next century in search of answers to fundamental questions about the exact composition of our star and the birth of our solar system KSC01padig255
