Answer: The launch on January 28, 1986, was different. The sun had been up for less than an hour and air temperatures were a few notches above freezing when the crew of STS-51L boarded the orbiter Challenger that Tuesday morning. All around the country people were getting excited—in large part because the seven-person crew’s included Payload Specialist Christa McAuliffe, a schoolteacher and mother of two chosen to fly as part of NASA’s Teacher in Space program. As a civilian, she was PR catnip: infinitely relatable and proof that space was now truly open to average Americans, not just hot-shot fighter jocks. Kids nationwide would watch the launch live and know that no dream was beyond reach.But 73 seconds after Challenger’s launch, that dream quickly became a nightmare. Challenger disappeared as white vapor bloomed from the external tank. Spectators were stunned. Teachers scrambled to get their kids out to recess.
