S99-05718 (26 May 1999) --- Astronaut Janet L. Kavandi, mission specialist, checks her communications head gear as she stands on a movable platform. Minutes later she was lowered into a nearby deep pool for an underwater training session at the Johnson Space Center's Neutral Buoyancy Laboratory (NBL), part of the Sonny Carter Training Center. Kavandi has weights on the training version of her extravehicular mobility unit (EMU) which help to provide neutral buoyancy in the pool. Astronauts Kavandi and Gerhard P.J. Thiele were participating in a rehearsal of a contingency space walk.

JSC2006-E-54836 (23 Dec. 2006) --- In this scene at Ellington Field, European Space Agency astronaut Thomas Reiter (second left, foreground) shakes hands with JSC deputy director Robert D. Cabana. Reiter had just arrived from Florida, along with the STS-116 crew. He completed half a year aboard the International Space Station before departing the station with the STS-116 astronauts, who landed at the Kennedy Space Center on Dec. 22. Part of Reiter's time onboard the orbital outpost was spent with astronaut Jeffrey N. Williams, left, Expedition 13 flight engineer and NASA station science officer. ESA astronaut Gerhard Thiele is also pictured.

The STS-99 crew wave to onlookers as they leave the Operations and Checkout Building enroute to Launch Pad 39A and liftoff of Space Shuttle Endeavour, targeted for 12:47 p.m. EST. In their orange launch and entry suits, they are (foreground) Pilot Dominic Gorie and Commander Kevin Kregel. Behind them (left to right) are Mission Specialists Janice Voss (Ph.D.), Mamoru Mohri (Ph.D.), Gerhard Thiele and Janet Lynn Kavandi (Ph.D.). Mohri is with the National Space Development Agency (NASDA) of Japan, and Thiele is with the European Space Agency. The SRTM will chart a new course to produce unrivaled 3-D images of the Earth's surface, using two antennae and a 200-foot-long section of space station-derived mast protruding from the payload bay. The result of the Shuttle Radar Topography Mission could be close to 1 trillion measurements of the Earth's topography. Besides contributing to the production of better maps, these measurements could lead to improved water drainage modeling, more realistic flight simulators, better locations for cell phone towers, and enhanced navigation safety. The mission is expected to last about 11days, with Endeavour landing at KSC Friday, Feb. 11, at 4:55 p.m. EST

KENNEDY SPACE CENTER, FLA. -- Space Shuttle Endeavour prepares to land on KSC's Shuttle Landing Facility Runway 33 to complete the 11-day, 5-hour, 38-minute-long STS-99 mission. Main gear touchdown was at 6:22:23 p.m. EST Feb. 22 , landing on orbit 181 of the mission. Nose gear touchdown was at 6:22:35 p.m.. EST, and wheel stop at 6:23:25 p.m. EST. At the controls are Commander Kevin Kregel and Pilot Dominic Gorie. Also onboard the orbiter are Mission Specialists Janet Kavandi, Janice Voss, Mamoru Mohri of Japan and Gerhard Thiele of Germany. Mohri is with the National Space Development Agency (NASDA) and Thiele is with the European Space Agency. The crew are returning from the Shuttle Radar Topography Mission, after mapping more than 47 million square miles of the Earth. This was the 97th flight in the Space Shuttle program and the 14th for Endeavour, also marking the 50th landing at KSC, the 21st consecutive landing at KSC, and the 28th in the last 29 Shuttle flights

The STS-99 crew poses in front of the Shuttle Radar Topography Mission (SRTM) in the Space Station Processing Facility. The crew has been checking out the SRTM, which is the payload for their mission. From left are Mission Specialists Janet Lynn Kavandi (Ph.D.), Mamoru Mohri of Japan, and Gerhard Thiele of Germany; Pilot Dominic L. Pudwill Gorie; Mission Specialist Janice Voss (Ph.D.); and Commander Kevin R. Kregel. Mohri represents the National Space Development Agency of Japan and Thiele represents the European Space Agency. An international project spearheaded by the National Imagery and Mapping Agency and NASA, with participation of the German Aerospace Center DLR, the SRTM consists of a specially modified radar system that will gather data for the most accurate and complete topographic map of the Earth's surface that has ever been assembled. SRTM will make use of radar interferometry, wherein two radar images are taken from slightly different locations. Differences between these images allow for the calculation of surface elevation, or change.

KENNEDY SPACE CENTER, Fla. -- At the 195-foot level of the Fixed Service Structure on Launch Pad 39A, the STS-99 crew pose for a photograph during Terminal Countdown Demonstration Test (TCDT) activities. Standing left to right are Pilot Dominic Gorie, Mission Specialist Mamoru Mohri (Ph.D.), Mission Specialist Janice Voss (Ph.D.), Commander Kevin Kregel, Mission Specialist Janet Lynn Kavandi (Ph.D.), and Mission Specialist Gerhard Thiele (Ph.D.). Thiele is with the European Space Agency and Mohri is with the National Space Development Agency (NASDA) of Japan. The TCDT provides the crew with simulated countdown exercises, emergency egress training, and opportunities to inspect the mission payloads in the orbiter's payload bay. STS-99 is the Shuttle Radar Topography Mission, which will chart a new course, using two antennae and a 200-foot-long section of space station-derived mast protruding from the payload bay to 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. Besides contributing to the production of better maps, these measurements could lead to improved water drainage modeling, more realistic flight simulators, better locations for cell phone towers, and enhanced navigation safety.

On the runway at the Shuttle Landing Facility, STS-99 crew members Pilot Dominic Gorie, Mission Specialist Janice Voss, Commander Kevin Kregel and Mission Specialist Gerhard Thiele discuss departure plans to Houston. Kregel and Gorie will be piloting T-38 jets with Voss and Thiele as passengers. During the Jan. 31 launch countdown, Endeavour's enhanced master events controller (E-MEC) No. 2 failed a standard preflight test. Launch was postponed and Shuttle managers decided to replace the E-MEC located in the orbiter's aft compartment. Launch controllers will be in a position to begin the STS-99 countdown the morning of Feb. 6 and ready to support a launch midto latenext week pending availability of the Eastern Range. The postponed launch gives the crew an opportunity for more training and time with their families.
