The unmanned, and possibly manned, flights are planned for this year. Charles Elachi, director of Jet Propulsion Laboratory, NASA’s leading center for planetary research says, while investigators are seeking the cause of Columbia’s failure, NASA continues its quest at space centers like JPL in Pasadena, California.
