New NASA video honors fallen astronauts of Apollo 1, Challenger and Columbia

NASA released a new video today (Jan. 27) to remember the three crews and other fallen astronauts who lost their lives in the pursuit of space exploration.

The agency’s annual “Day of Remembrance” falls this year on the 55th anniversary of the Apollo 1 fire of Jan. 27, 1967. The week that follows includes two other somber anniversaries mentioned in the video: the Challenger shuttle disaster of Jan. 28, 1986 and the Columbia shuttle accident of Feb. 1, 2003.
