Charles Stark Draper
NASA's Johnson Space Center leads the ALHAT project, begun in early 2006, for NASA's Exploration Technology Development Program. Support is also provided by Charles Stark Draper Labs and the Johns Hopkins Applied Physics Laboratory, Baltimore. Langley designed two special-purpose light detection and ranging (lidar) sensors. In conjunction with this, NASA's Jet Propulsion Laboratory developed algorithms for analysing the terrain based upon these lidar measurements.
