The challenger disaster

Obviously a major malfunction," the NASA launch commentator said as pieces of the shuttle fell from the sky into the Atlantic. Salvage crews spent several weeks recovering pieces of the shuttle and carefully, bringing up the remains of the seven astronauts. Millions more watched the wrenching tragedy unfold on live television.

In particular Robert Hobbs who plays Allan J Macdonald a man torn between doing what is right whilst realizing the personal cost that might result. Ten years after the Challenger disaster, two large pieces from the spacecraft washed ashore on a Florida beach.

Challenger disaster

Investigations by Morton-Thiokol engineers determined that the amount of damage to the O-rings was directly related to the time it took for extrusion to occur, and that cold weather, by causing the O-rings to harden, lengthened the time of extrusion.

Major parts of STA, including the payload bay doors, body flap, wings, and vertical stabilizer, also had to be returned to their individual subcontractors for rework. At a commission hearing, Feynman convincingly demonstrated the loss of O-ring resiliency by submerging an O-ring in a glass of ice water.

The two solid-rocket boosters continued flying until the NASA range safety officer destroyed them by remote control. Work continued on the conversion until July Perhaps most concerning was the launch of STSB in Aprilflown by Challenger, in which the worst O-ring damage to date was discovered in post-flight analysis.

However, after the Challenger disaster, Thiokol engineer Brian Russell identified this event as the first "big red flag" regarding O-ring safety.

Three decades after the Challenger disaster, Christa McAuliffe's lessons will finally be taught

Nelson and crewmate James "Ox" Van Hoften repaired the satellite together, then the crew lofted the satellite back into space. Challenger broke up in the explosion, but the forward section with the crew cabin was severed in one piece; it continued to coast upward with other debris, including wings and still-flaming engines, and then plummeted to the ocean.

At the same time, thrust in the booster lagged slightly, although within limits, and the nozzle steering systems tried to compensate. Review of film shot by pad cameras showed that the arm did not re-contact the vehicle, and thus it was ruled out as a contributing factor in the accident.

Temperatures dipped below freezing. Challenger at a glance First flight: Seventy-three seconds later, hundreds on the ground, including the families of McAuliffe and the other astronauts on board, stared in disbelief as the shuttle broke up in a plume of smoke and fire.

January Learn how and when to remove this template message Gray smoke escaping from the right side SRB The following account of the accident is derived from real time telemetry data and photographic analysis, as well as from transcripts of air-to-ground and mission control voice communications.

McAuliffe was to conduct at least two lessons from orbit and then spend the following nine months lecturing students across the United States.

Although this reliance on the shuttle was the officially stated national space policy, the Department of Defense began to retreat from relying exclusively on the shuttle even before the Challenger accident.

The commission also found that Morton Thiokol, the company that designed the solid rocket boosters, had ignored warnings about potential issues. An inspection of the launch pad revealed large quantities of ice collecting due to unusually cold overnight Florida temperatures.

Her role in the Rogers Commission remains a mystery and we only learn of it just before the credits roll. Then, Nelson carefully left the safety of the shuttle and flew over to the satellite. Challenger liftoff and explosion at Cape Canaveral, Florida, January 28, 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.

I feel the use of camera positioning where half the frame is blocked was at first novel, but maybe repeated too often and in some scenes it would have been better to allow the subject to take up the full frame.

The Space Shuttle Challenger Disaster: What Happened? (Infographic)

The shuttle program had neither the personnel nor the spare parts to maintain such an ambitious flight rate without straining its physical resources or overworking its technicians.

The qualification tests were used to validate computational models, and compliance with the required 1. James Hawes directs with firmness and allows the story to flow and develop with fascinating insights into Feynman the scientist, but also Feynman the man and husband who had to fight his own person battles as a subplot.

They did not call for a halt to shuttle flights until the joints could be redesigned, but rather treated the problem as an acceptable flight risk. On launch day, January 28, liftoff was delayed until This made it possible for combustion gases to erode the O-rings.

In a second test on Jan. Rogers Chairman and, former secretary of state exudes the physical appearance of a persuasive man who has his own agenda and delivers a powerful performance.

Challenger Explosion

Famously, scientist Richard Feynman, a member of the commission, demonstrated the O-ring flaw to the public using a simple glass of ice water. Rockwell engineers watching the pad from their headquarters in Downey, Californiawere horrified when they saw the amount of ice.

It successfully completed nine milestone missions. According to NASA, computer models at the time were not sophisticated enough to calculate the stresses on the shuttle during different phases of flight. Cultural and technical problems A presidential commission was convened to look into the incident, chaired by former attorney general and secretary of state William P.
