jsc2019e070461 (12/13/2019) --- A preflight view taken of the ISS Universal Waste Management System, Unit 1 during EMI/EMC Testing. This technology provides additional waste disposal points to the International Space Station (ISS) and aids in planning for future exploration missions including Deep Space Gateway (DSG).

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

Posing for the traditional preflight crew portrait, the seven astronauts of the STS-109 mission are (left to right) astronauts Michael J. Massimino, Richard M. Linnehan, Duane G. Carey, Scott D. Altman, Nancy J. Currie, John M. Grunsfeld and James H. Newman. Altman and Carey were commander and pilot, respectively, with the others serving as mission specialists. Grunsfeld was payload commander. Launched aboard the Space Shuttle Columbia on March 1, 2002, the group was the fourth visit to the the Hubble Space Telescope (HST) for performing upgrade and servicing on the giant orbital observatory.

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

KENNEDY SPACE CENTER, FLA. -- McDonnell Douglas-SPACEHAB technicians prepare to place a Russian-made oxygen generator into position for transport in a SPACEHAB Double Module being processed for flight on Space Shuttle Mission STS-84. The module is undergoing preflight preparations in the SPACEHAB Payload Processing Facility just outside of Gate 1 on Cape Canaveral Air Station. The Space Shuttle Atlantis will carry the oxygen generator to the Russian Space Station Mir to replace one of two Mir units that have been malfunctioning recently. The nearly 300-pound generator functions by electrolysis, which separates water into its oxygen and hydrogen components. The hydrogen is vented and the oxygen is used for breathing by the Mir crew. The generator is 4.2 feet long with a diameter of 1.4 feet. STS-84, which is planned to include a Mir crew exchange of astronaut C. Michael Foale for Jerry M. Linenger, is targeted for a May 15 launch. It will be the sixth Shuttle-Mir docking

In this Spacelab-1 mission onboard photograph, astronaut Byron Lichtenberg performs a drop experiment, one of the Vestibular Experiments in Space investigations. The experiment examined spinal reflexes to determine whether they changed in microgravity. In Earth's environment, the otoliths signal the muscles to prepare for jolts associated with falling. During the flight, the normal reflex between the otoliths and the muscles was partially inhibited early in flight, declined further as the flight progressed, and returned to normal immediately after landing, suggesting that the brain ignored or reinterpreted otolith signals during space flight. Crewmembers reported a lack of awareness of position and location of feet, difficulty in maintaining balance, and a perception that falls were more sudden, faster, and harder than similar drops experienced in preflight. Crewmembers experienced illusions as they performed prescribed movement tests. When crew members viewed various targets and then pointed at them while blindfolded, their perception of target location and position of their own limbs was inaccurate in flight compared with similar tests on the ground. The Spacelab-1 was a multidisciplinary mission; that is, investigations were performed in several different fields of scientific research. The overall goal of the mission was to verify Spacelab performance through a variety of scientific experiments. The Spacelab-1 was launched aboard the Space Shuttle Orbiter Columbia for the STS-9 mission on November 28, 1983. The Marshall Space Flight Center had management responsibilities for the mission.
