In honor of fallen astronauts -
NASA assigned today as a day of remembrance for astronauts that were killed in three major agency tragedies:
- Apollo 1 in 1967: A fire broke out in the capsule, killing astronauts Gus Grisson, Ed White and Roger Chaffee
- The space shuttle Challenger in 1986: An O-ring failure caused the shuttle to explode after liftoff, killing astronauts Francis “Dick” Scobee, Ronald McNair, Mike Smith, Ellison Onizuka, Judy Resnik, Greg Jarvis and Connecticut teacher Christa McAuliffe
- The Colombia shuttle in 2003: The shuttle broke apart during re-entry, killing astronaut Rick Husband; pilot Willie McCool; mission specialists Kalpana Chawla, Laurel Clark and David Brown; payload commander Michael Anderson; and payload specialist (and first Israeli astronaut) Ilan Ramon.
