STS099-729-086 (11-22 February 2000) ---In this 70mm frame photographed by one of the STS-99 crew members, the city of Miami encroaches the eastern edge of the Everglades in Florida. The Everglades is an International Biosphere Reserve World Heritage Site. This subtropical wilderness encompasses a relatively flat (does not exceed 2.4 meters above sea level) saw-grass marsh region of 10,000 square kilometers (4,000 square miles). The only source of water in the Everglades is from rainfall. The flow of water is detectable in this image, slowly moving from Lake Okeechobee to Florida Bay; the light blue, shallow area (less than 3 meters) between the mainland and the Keys; and the southwestern Florida coast.

JSC2000E01552 (January 2000) --- This chart compares currently available global map data with the data which will be provided by SRTM during STS-99. The area depicted is the California coast. The SRTM mission will have approximately 1,000 scheduled data takes (every time Endeavour is over land). Data acquisition will be conducted in excess of 80 hours. The recording rate for data will be 180 Mbits/sec for C-band, 90 Mbits/sec for X-band. Total raw radar data will be approximately 9.8 terabytes (15,000 CDs). The mission will utilize some 300 high-density tapes (each tape records 30 min. of C-band, or 60 min. of X-band data).

STS099-714-060 (11-22 February 2000) ---One of the STS-99 astronauts aboard the Space Shuttle Endeavour recorded this 70mm image of Cairo, one of the fastest growing cities in the world. The city is moving outside the dark-colored Nile valley into the surrounding desert. New developments are side by side with ancient monuments.

Further south of the Giza pyramids on the west side of the Nile River are the Step and Bent Pyramids, respectively.

STS099-722-077 (11-22 February 2000) ---Both topography and bathymetry combine with wind and sea currents to produce a pattern of sea ice in the extreme southern Sea of Okhotsk, in this scene photographed by one of the STS-99 crew members aboard the Space Shuttle Endeavour. The rugged shoreline of north Hokkaido and the Kurile Archipelago have channeled northerly winds and surface waters into a gyre here, clearly depicted in the pattern of sea ice.

STS099-356-026 (11-22 February 2000) ---Because of its time exposure, this STS-99 35mm frame provides a view of several stars. The thin greenish band above the horizon is airglow; radiation emitted by the atmosphere from a layer about 30 kilometers thick and about 100 kilometers altitude. The predominant emission in airglow is the green 5577-Angstrom wavelength emission from atomic oxygen atoms. Airglow is always and everywhere present in the atmosphere; it results from the recombination of molecules that have been broken apart by solar radiation during the day. But airglow is so faint that it can only be seen at night by looking "edge on" at the emission layer, such as the view astronauts have in orbit.

STS099-329-019 (11-22 February 2000) --- Astronaut Janet L. Kavandi, mission specialist, appears joyous over the success of the Shuttle Radar Topography Mission (SRTM) and other experiments on the flight deck of the Space Shuttle Endeavour. The Red Team member is standing beneath an electronic still camera (ESC) mounted in Endeavour's overhead windows. The camera stayed busy throughout the ll-day mission taking vertical imagery of Earth points of opportunity for the EarthKAM project. Students across the United States and in France, Germany and Japan took photos throughout the STS-99 mission. And they are using these new photos, plus all the images already available in the EarthKAM system, to enhance their classroom learning in Earth and space science, social studies, geography, mathematics and more.

STS099-706-090 (11-22 February 2000) ---One of the astronauts aboard the Space Shuttle Endeavour for the STS-99 mission recorded this 70mm image of Hannah Bay, in the southern part of St. James Bay. The river is the Harricanaw River. Numerous shorelines around Hudson and St. James Bays are distinctive in winter because of snow cover. According to NASA scientists, shorelines were created when the overlying glaciers retreated and the land underneath rebounded causing the Hudson and St. James Bay waters to retreat northward. These ridges are 100 to 200 meters in width and heights can reach up to 7 meters. The land along St. James Bay consists mainly of tidal flats and salt marshes.
S99-E-5705 (18 February 2000) --- Astronauts Mamoru Mohri (left), mission specialist, and Dominic L. Gorie, pilot, on the flight deck of the Space Shuttle Endeavour.

STS099-314-035 (11-22 February 2000) ---Astronaut Kevin R. Kregel, mission commander, works with camera equipment, which was used for the EarthKAM project. The camera stayed busy throughout the 11-day mission taking vertical imagery of the Earth points of opportunity for the project. Students across the United States and in France, Germany and Japan took photos throughout the STS-99 mission. And they are using these new photos, plus all the images already available in the EarthKAM system, to enhance their classroom learning in Earth and space science, social studies, geography, mathematics and more.
S99-E-5555 (17 February 2000) --- As photographed from the Space Shuttle Endeavour, this oblique electronic still image of Earth's horizon reveals a great deal of cloud cover. In the case of the electronic still camera (ESC), as well as film-bearing instruments, clouds naturally obscure views of recognizable land masses. Much of Earth is heavily cloud covered during the current mission and meteorlogists and oceanographers are interested in studying that aspect. However, the Shuttle Radar Topography Mission's other sensing equipment, X-SAR and C-band antennae, are able to penetrate cloud cover and record important topographic data for mapmakers and scientists of other disciplines. In addition to the sensing equipment mentioned above, this mission is supporting the EarthKAM project which utilizes the services of another electronic still camera mounted in Endeavour's windows. Unlike this oblique view, EarthKAM records strictly vertical or nadir imagery of points all over the world. Students across the United States and in France, Germany and Japan are taking photos throughout the STS-99 mission. And they are using these new photos, plus all the images already available in the EarthKAM system, to enhance their classroom learning in Earth and space science, social studies, geography, mathematics and more.

STS099-727-045 (11-22 February 2000) ---One of the astronauts aboard the Space Shuttle Endeavour for the STS-99 mission recorded this 70mm image of Long Island, New York. The entire length of Long Island is visible in partial sunglint from Lower Bay to Block Island Sound. According to geologists, the origin and shape of Long Island are due to continental collision and glaciers that once dominated the landscape. A collision between North America and Africa about 300 million years ago caused the Appalachian Mountains to rise, they say. Streams carried sediment from the eroding Appalachians and also carved a valley that would one day become Long Island Sound. The scientists went on to say that retreating ice sheets 22,000 years ago allowed the land to rebound with the highest points becoming Long Island.

KENNEDY SPACE CENTER, Fla. -- Space Shuttle Endeavour is viewed atop the mobile launcher platform on its way to Launch Pad 39A for launch of mission STS-99. Named the Shuttle Radar Topography Mission (SRTM), STS-99 involves an international project spearheaded by the National Imagery and Mapping Agency and NASA, with participation of the German Aerospace Center DLR. SRTM will chart a new course, using two antennae and a 200-foot-long section of space station-derived mast protruding from its 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. STS-99 is scheduled for launch in January 2000
