Today is NASA’s Day of Remembrance, honoring those who have lost their lives furthering the cause of exploration and discovery.  Today falls in the middle of anniversaries of three NASA tragedies:  the Apollo 1 accident during a training session on January 27, 1967; the Columbia space shuttle explosion following launch on January 28, 1986; and the breakup of the Columbia space shuttle during re-entry on February 1, 2003.   There have been many other people who have lost their lives while working for NASA, and we remember them, as well.  There was a wreath-laying ceremony at Kennedy Space Center this morning.

NASA has an interactive feature in honor of the three crews.
