At Launch Plus 66.8 seconds, ET pressure dropped dramatically. At Launch Plus 64.66 seconds, the burn-through plume penetrated the ET, which began to lose pressure as a result.Īt Launch Plus 64.705 seconds, a bright glow formed between the right SRB and the ET. At roughly this same time, telemetry data indicated that the pressure of the right SRB had become lower than that of the left SRB.Īt Launch Plus 62 seconds, telemetry data indicated that the Orbiter’s automated guidance control system had begun responding to the dynamic forces caused by the burn-through plume. By Launch Plus 3.375 seconds, the smoke was no longer visible.Īt Launch Plus 58.788 seconds, a burn-through plume was seen emerging from the aft field joint of the right SRB. The puff of smoke was pinpointed to have emerged from between the 270 degree and 310 degree circumference points of the aft field joint, directly between the right SRB and the External Tank (ET).

The puff of smoke achieved its highest level of visibility at Launch Plus 1.9 seconds. This indicated that the aft field joint was not completely sealed. 678 seconds, a large puff of grayish black smoke was seen emerging from the aft field joint of the right Solid Rocket Booster (SRB). All of Challenger’s pre-launch preparations were routine, with the exception of tremendous ice buildup on the launch pad that formed as temperatures dipped into the low 20’s overnight.Īt Launch Plus.

This was 15 degrees colder than any previous Space Shuttle launch. Telemetry data was also reviewed, as was debris evidence recovered from the Atlantic Ocean.Īfter a thorough analysis of the camera images and telemetry data was completed, the following scenario of events leading up to the Challenger explosion emerged:Īt launch time, the temperature at the Kennedy Space Center was 36 degrees Fahrenheit. The Rogers Commission quickly assumed the task of reviewing video, film and still images from about 200 cameras that photographed the launch and explosion of Challenger. The group became popularly known as the Rogers Commission after its Chairman, William P. Soon after the Challenger explosion, President Ronald Reagan formed the Presidential Commission on the Space Shuttle Challenger Accident. Challenger exploded 73 seconds after launch, and a crew of seven astronauts perished.

'They 'dreamed big,' devoting their careers and their hearts to help our nation explore space. 'Thousands of people in Friendswood were devoted to the Apollo and Space Shuttle programs,' said mayor Mike Foreman in a statement. 28 anniversary of Challenger and the 1967 Apollo I disaster were especially hard on the Houston area and the Johnson Space Center. The Columbia Accident Investigating Board rebuilt it piece by piece inside a hangar at the Kennedy Space Center. In the Columbia accident, pieces were left scattered across several states. 27, 1967, while the Columbia disaster that killed seven happened on Feb. The Apollo 1 fire that killed three was on Jan. It also remembers those who died in the Apollo 1 and Columbia accidents. NASA observes a Day of Remembrance on Jan. 'The Challenger crew was pulling us into the future, and we'll continue to follow them.' 'The future doesn't belong to the faint-hearted. I am rather confident that it is one of the largest pieces ever found of Challenger,' NASA program manager, Mike Ciannilli said.īecause of the proximity to the Florida Space Coast, the item's modern construction and the presence of 8-inch square tiles, the documentary team contacted NASA, who wanted to ensure that the surviving family members of the Challenger crew were notified first.

The dive team was working for a History Channel documentary about the Bermuda Triangle and looking for wreckage of a World War II-era aircraft when they noticed a large humanmade object covered partially by sand on the seafloor, NASA says. NASA officials tell ABC13 that a 20-foot segment of the shuttle was discovered and recovered by divers off the East coast of Florida. NASA said that it's 'carefully considering additional actions to take that will properly honor the legacy of the Challenger, the crew members who were lost, and the families who loĪ stunning discovery has been made 36 years after the Challenger space shuttle disaster.
