High above the Kennedy Space Center and the Florida Atlantic coastline, the Space Shuttle Challenger heads toward its second Earth-orbital mission. The orbiter, its two-solid rocket boosters and external fuel tank are just a tiny dot atop the rapidly-lengthening plume of steam. Astronaut John W. Young, piloting the Shuttle training aircraft (STA) for his traditional weather-monitoring flight, used a 70mm handheld-Hasselblad to record this scene. Launch occurred at 7:33 a.m. (EDT) today.
