That's all appropriate because today is NASA's Day of Remembrance:
On the eve of the 25th anniversary of the space shuttle Challenger accident, Kennedy Space Center observed NASA's Day of Remembrance, Jan. 27, with a wreath-laying ceremony at the KSC Visitor Complex Space Mirror Memorial. The Day of Remembrance honors members of the NASA family who lost their lives while furthering the cause of exploration and discovery, including the astronaut crews of Apollo 1 and shuttles Challenger and Columbia.
