"NASA's three space-related fatalities occurred within days of one another but years apart. Three astronauts were killed in the Apollo 1 launch pad fire on Jan. 27, 1967. Seven more died aboard Challenger on Jan. 28, 1986. And the seven-member crew of Columbia perished during re-entry on Feb. 1, 2003."
