The Space Shuttle Challenger was destroyed 73 seconds after lift-off on STS-51-L at an altitude of 15 kilometers (49,000 ft). The investigation found that cold weather conditions caused an O-ring seal to fail, allowing hot gases from the shuttle's solid rocket booster (SRB) to impinge on the external propellant tank and booster strut.
STS-51-L was the disastrous 25th mission of NASA's Space Shuttle program and the final flight of Space Shuttle Challenger. It was planned as the first Teacher in Space Project flight in addition to observing Halley's Comet for six days and performing a routine satellite deployment.
Feynman's suspicions were corroborated by General Kutyna, also on the commission, who cunningly [10] provided Feynman with a broad hint by asking about the effect of cold on O-ring seals after mentioning that the temperature on the day of the launch was far lower than had been the case with previous launches: below freezing at 28 to 29 °F (− ...
STS-51-L was the twenty-fifth flight in the American Space Shuttle program, and marked the first time a civilian had flown aboard the Space Shuttle. The mission used Space Shuttle Challenger , which lifted off from launch pad 39B (LC-39B) on January 28, 1986, from Kennedy Space Center , Florida .
A few seconds later, the message came through from mission control: No rocket launch today. Instead the mission will launch from the base near Lompoc during the backup window on Friday at 10:39 a ...
Here’s how long the mission to deliver military satellites into orbit from Vandenberg Space Force Base could be delayed. SpaceX rocket launch from Vandenberg canceled seconds before blastoff ...
In the context of a rocket launch, the "L minus Time" is the physical time before launch, e.g. "L minus 3 minutes and 40 seconds". "T minus Time" is a system to mark points at which actions necessary for the launch are planned - this time stops and starts as various hold points are entered, and so doesn't show the actual time to launch. The ...
REM’s original line-up was broken in 1997 with the departure of Berry, after he suffered a double brain aneurysm while on stage in Switzerland during their world tour. The remaining three ...
