Kalpana Chawla (July 1, 1961 – 1 February 2003), you may remember, was an Indian-born American astronaut and a space shuttle mission specialist.
She was, unfortunately, one of seven crew members lost aboard Space Shuttle Columbia during mission STS-107, when the shuttle disintegrated upon reentry into the Earth's atmosphere.
