KENNEDY SPACE CENTER, Fla. -- At the 167-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 Mission Specialist Janet Lynn Kavandi (Ph.D.), Commander Kevin Kregel, Mission Specialists Janice Voss (Ph.D.), Gerhard Thiele and Mamoru Mohri, and Pilot Dominic Gorie. Thiele is with the European Space Agency and Mohri is with the National Space Development Agency (NASDA) of Japan. Behind them (left) are visible the top of a solid rocket booster (white) and external tank (orange). 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. Launch of Endeavour on the 11-day mission is scheduled for Jan. 31 at 12:47 p.m. EST KSC00pp0044

KENNEDY SPACE CENTER, Fla. -- At Launch Pad 39A, STS-99 Mission Specialists Gerhard Thiele (Ph.D.), of the European Space Agency (in front), and Janet Kavandi (Ph.D.) prepare to practice emergency egress procedures with a slidewire basket. Seven slidewires, with flatbottom baskets suspended from each wire, extend from the Fixed Service Structure at the orbiter access arm level. These baskets could provide an escape route for the astronauts until the final 30 seconds of the countdown in case of an emergency.

KENNEDY SPACE CENTER, Fla. -- At Launch Pad 39A, STS-99 Mission Specialists Mamoru Mohri (Ph.D.), who is with the National Space Development Agency (NASDA) of Japan, and Janice Voss (Ph.D.) practice emergency egress procedures in a slidewire basket. Seven slidewires, with flatbottom baskets suspended from each wire, extend from the Fixed Service Structure at the orbiter access arm level. These baskets could provide an escape route for the astronauts until the final 30 seconds of the countdown in case of an emergency. The crew is taking part in Terminal Countdown Demonstration Test (TCDT) activities that provide 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. Launch of Endeavour on the 11-day mission is scheduled for Jan. 31 at 12:47 p.m. EST KSC-00pp0072

STS-99 Mission Specialist Gerhard P.J. Thiele (Ph.D.), with the European Space Agency, arrives at KSC aboard a T-38 jet aircraft to prepare for launch of Endeavour Jan. 31 at 12:47 p.m. EST. 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 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 KSC-00pp0105

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 KSC-00pp0127

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. Endeavour is expected to land at KSC Friday, Feb. 11, at 4:55 p.m. EST KSC-00pp0118

STS-99 Mission Specialist Gerhard Thiele (foreground) and Commander Kevin Kregel make their way to the runway at the Shuttle Landing Facility for a return flight to Houston. 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 late next week pending availability of the Eastern Range. The postponed launch gives the crew an opportunity for more training and time with their families.
