� Remembering the Crew of Challenger STS-51-L � On January 28, 1986, at 11:38 AM EST, seven brave astronauts embarked on a mission of exploration and discovery aboard the Space Shuttle Challenger. Tragically, just 73 seconds into their journey, the mission ended in disaster. Today, we honor their memory and their contributions to science, exploration, and humanity's pursuit of knowledge. Join us as we rebroadcast the launch to reflect on their courage and sacrifice. Let’s remember: � Christa McA
