Today, 31 years later, we remember the crew of the Space Shuttle Challenger.
The NASA family lost seven of its own on the morning of January 28, 1986, when a booster engine failed, causing the Shuttle Challenger to break apart just 73 seconds after launch.
In this photo from January 9, 1986, the Challenger crew takes a break during countdown training at NASA’s Kennedy Space Center.

(Dick) Scobee, mission commander; Ronald E. McNair, mission specialist; Mike J. Smith, pilot; and Ellison S. Onizuka, mission specialist.
