On Jan. 28, 1986, NASA faced its first shuttle disaster, the loss of the Challenger orbiter and its seven-astronaut crew.

Twenty-five years ago today, NASA's space shuttle Challenger exploded and broke apart just after liftoff, killing seven astronauts – including civilian teacher Christa McAuliffe – in one of the worst space disasters in U.S. history.
The 1986 space shuttle Challenger disaster was NASA's first public spaceflight failure and second fatal spaceflight failure. Every year at this time, NASA remembers the Challenger crew, as well as the seven astronauts killed on the shuttle Columbia during re-entry on Feb. 1, 2003, and three Apollo 1 astronauts who died in a pad fire aboard their capsule on Jan. 27, 1967.
Challenger's ill-fated flight, STS-51L, gained wide attention because of the presence of New Hampshire high school teacher Christa McAuliffe on the shuttle's crew as NASA's first Teacher in Space. She was joined by Challenger mission commander Richard "Dick" Scobee, pilot Michael J. Smith, mission specialists Ronald McNair, Ellison Onizuka, Judith Resnik and payload specialist Gregory Jarvis.
Here's a look at the Challenger space shuttle disaster, why it happened and its impact now 25 years later:
