A day of Remembrance

Today is Nasa’s official day of remembrance, for all of the astronauts who have sacrificed their lives for our further understanding of where we are, and the things around us. Specifically the crew members of Apollo 1, who burned to death in an oxygen saturated simulation capsule, the Challenger crew, who died when their Shuttle exploded shortly after launch, and the Crew of the Space Shuttle Columbia, who died when their shuttle disintegrated during its decent to earth.  Take a moment to think about the guts these people have.
