Hey Space Placers!
Today, February 1 is NASA's Day of Remembrance for the crews of Apollo 1, Challenger and Columbia. Visit NASA http://www.nasa.gov/externalflash/DOR2013/index.html to read about the missions and their crews.
Pause and remember today their collective sacrifices that in turn led to changes in hardware and protocols to make manned spaceflight safer.
