Computer programs that are used to define safety margins for fiery spacecraft re-entries and help detect planets outside our solar system are co-winners of NASA's 2007 Software of the Year Award.

Software engineers at NASA's Ames Research Center developed the Data-Parallel Line Relaxation, or DPLR, which is used to analyze and predict the extreme environments human and robotic spacecraft experience during super high-speed entries into planetary atmospheres.

At NASA's Jet Propulsion Laboratory, software engineers developed the Adaptive Modified Gerchberg-Saxton Phase Retrieval program. The software uses a telescope's science camera with innovative and robust algorithms to characterize possible errors that limit its imaging performance. The September issue of NASA Tech Briefs will feature further coverage of the 2007 Software of the Year Award.
