NASA's space shuttle Challenger completed 10 missions before it broke apart during a launch in 1986, killing seven astronauts.

Cold temperatures inhibited the space shuttle Challenger’s infrastructure from working properly. NASA has set potential weather conditions that would stop Artemis II from launching as scheduled.

NASA's space shuttle Challenger exploded and broke apart Jan. 28, 1986, in the sky over East-Central Florida, killing the seven astronauts on board.

NASA is getting ready to launch its massive, fully expendable rocket for the first crewed flight to the Moon since Apollo. The agency’s new era of spaceflight comes with a few parts from its past, specifically three rocket engines that have previously flown on space shuttle missions.

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.

With the wet dress rehearsal, essentially a critical fueling test of the Artemis 2 Space Launch System moon rocket, now back on Feb. 2, NASA said in a statement that it can no longer target Feb. 6 or Feb. 7, the first two days of its launch window. The Artemis 2 launch window originally ran from Feb. 6 to Feb. 10.
