Framed by two immense billows of steam, Space Shuttle Endeavour breaks its Earthly tethers to soar into a clear blue sky. Liftoff of mission STS-99 occurred at 12:43:40 p.m. EST. Known as the Shuttle Radar Topography Mission (SRTM), STS-99 will chart a new course to produce unrivaled 3-D images of the Earth's surface. The result of the SRTM could be close to 1 trillion measurements of the Earth's topography. The mission is expected to last 11days, with Endeavour landing at KSC Tuesday, Feb. 22, at 4:36 p.m. EST. This is the 97th Shuttle flight and 14th for Shuttle Endeavour. {highres} 2670 x 2086 {highsize} 427905 {hightype} JPEG {lowres} 307 x 240 {lowsize} 104897 {lowtype} GIF {mediumres} 983 x 768 {mediumsize} 81724 {mediumtype} JPEG {number} KSC-00PD-5005 {othernumbers} KSC-00PADIG-005 {slideres} 165 x 156 {slidesize} 37098 {slidetype} GIF {tinyres} 100 x 78 {tinysize} 11835 {tinytype} GIF {title} A perfect launch on a perfect Florida day! {type} Image {end}
