Vision and Mission of launching Challenger in Space

The Vision of launching Challenger in space was to make an ordinary Citizen of America to go to Space for the first time in World. Christa McAuliffe was selected for taking her up to the Space. She was a Beloved and Favourite Teacher of her Students in a school. It was planned that she will show her students some Experiments in Zero Gravity live on TV. There were 5 Astronauts and 2 Payload Specialists chosen to float in the Space.

Pre-Launch Conditions

Challenger was originally set to launch from KSC in Florida at 14:42 Eastern Standard Time (EST) on January 22. Delays in the previous mission, STS-61-C, caused the launch date to be moved to January 23 and then to January 24. The launch was then rescheduled to January 25 due to bad weather at the Transoceanic Abort Landing (TAL) site in Dakar, Senegal. NASA decided to use Casablanca as the TAL site, but because it was not equipped for night landings, the launch had to be moved to the morning (Florida time). Predictions of unacceptable weather at KSC on January 26, caused the launch to be rescheduled for 09:37 EST on January 27.

The launch was delayed the next day, due to problems with the exterior access hatch. First, one of the micro-switch indicators, used to verify that the hatch was safely locked, malfunctioned. Then, a stripped bolt prevented the closeout crew from removing a closing fixture from the orbiter’s hatch. By the time repair personnel had sawed the fixture off, crosswinds at the Shuttle Landing Facility exceeded the limits for a Return to Launch Site (RTLS) abort. While the crew waited for winds to die down, the launch window expired, forcing yet another scrub.

Forecasts for January 28 predicted an unusually cold morning, with temperatures close to −1 °C (30 °F), the minimum temperature permitted for launch. The Shuttle was never certified to operate in temperatures that low. The O-rings, as well as many other critical components, had no test data to support any expectation of a successful launch in such conditions.

At the Fixed Date of Launch…

The Challenger Space Shuttle launched on 28th January 1986. All the spectators were eagerly keeping an eye on the Shuttle. The students of Christa McAuliffe were jumping with joy at the time of launch and its going up movement in sky. Approximately 17 percent of Americans witnessed the launch live because of the presence of Payload Specialist Christa McAuliffe, who would have been the first teacher in space.

And the Disaster Started…

The Space Shuttle Challenger disaster occurred when the NASA Space Shuttle orbiter Challenger broke apart 73 Seconds into its flight, leading to the deaths of its Seven Crew members, which included Five NASA Astronauts and Two Payload Specialists. The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39 EST (16:39 UTC). Disintegration of the vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff.
