NASA's space shuttle Challenger completed 10 missions before it broke apart during a launch in 1986, killing seven astronauts.
The rollout on Saturday, Jan. 17, of the Space Launch System (SLS) rocket is a crucial step signaling that NASA is in the final stretches to get its first crewed lunar mission in five decades off the ground. That mission, known as Artemis 2, will send three Americans and one Canadian on a 10-day trip around the moon.
It’s been 40 years since the tragic Space Shuttle Challenger launch.
