NASA will pay tribute today (Feb. 7) to the 17 astronauts who died in the agency's three spaceflight tragedies.
NASA is holding a series of ceremonies around the country as part of its annual Day of Remembrance, which honors the astronauts who died in the 1967 Apollo 1 fire, the 1986 destruction of the space shuttle Challenger and the 2003 loss of the shuttle Columbia.
Accidents - Jan - Feb - Years - NASA
All of those accidents occurred between Jan. 27 and Feb. 1 in their respective years, so NASA holds the Day of Remembrance in late January or early February. This year's activities were originally scheduled to take place on Jan. 31 but were pushed back because of the 35-day government shutdown.
The headline event today will take place at 1 p.m. EST...
