Did they recover bodies from Challenger?
Within a day of the shuttle tragedy, salvage operations recovered hundreds of pounds of metal from the Challenger. In March 1986, the remains of the astronauts were found in the debris of the crew cabin.
What caused the Challenger explosion?
Hot gases from the rocket had slipped past the O-rings in two of the SRB segments. At roughly the 73-second mark after launch, the right SRB triggered the rupture of the external fuel tank. Liquid hydrogen and oxygen ignited, and the explosion enveloped Challenger.
How long did the Challenger crew survive?
The seven crew members of the space shuttle Challenger probably remained conscious for at least 10 seconds after the disastrous Jan. 28 explosion and they switched on at least three emergency breathing packs, the National Aeronautics and Space Administration said Monday.
Why did the Challenger explode for kids?
The shuttle broke up 73 seconds after take-off from Cape Canaveral on 28 January 1986. All seven astronauts who were on it at the time were killed. The crash happened because a rubber tube called an o-ring did not expand to fill a gap in one of the booster rockets, due to cold weather.
Did they ever find the Challenger crew?
The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39 a.m. EST (16:39 UTC). The crew compartment and many other vehicle fragments were recovered from the ocean floor after a three-month search and recovery operation.
How big was the O-ring that failed on the Challenger?
This is the joint that failed on the Right Solid Rocket Booster. The joint is sealed by two rubber O-rings, with a diameter of 0.280 inches (+ 0.005, -0.003). The sealing is used to stop the gases from inside the SRB escaping. The seal had failed, because the flame seen during the flight was gas being burnt.
Did the Challenger crew survive the blast?
The brave crew members — Smith, Dick Scobee, Ronald McNair, Ellison Onizuka, Judith Resnik, Gregory Jarvis and Christa McAuliffe — survived the initial disaster and “were conscious, at least at first, and fully aware that something was wrong,” author Kevin Cook writes in the new book “The Burning Blue: The Untold Story …
What happened to the Challenger for kids?
On January 28, 1986, the Space Shuttle Challenger broke apart during take-off. All of the seven crewmembers died in the accident including a schoolteacher from New Hampshire named Christa McAuliffe. What is a Space Shuttle? The Space Shuttle was the world’s first reusable manned spacecraft.
What were the last words of the Challenger crew?
Previously, the last known words from the Challenger were those heard from Commander Dick Scobee to ground controllers, when he responded ″Roger, go at throttle up,″ confirming that the shuttle’s main engines had been raised to full power.
Is Sally Ride Alive?

What is the truth about the Challenger explosion?
The space shuttle Challenger blew apart some 73 seconds after lifting off from Cape Canaveral, Florida in 1986, killing all seven astronauts on board. 1. The Challenger didn’t actually explode. The space shuttle was engulfed in a cloud of fire just 73 seconds after liftoff, at an altitude of some 46,000 feet (14,000 meters).
What are the effects of the Challenger explosion?
One of the most surprising effects of the Challenger explosion was the elevation of Richard Feynman from respected scientist well known in the field to international celebrity, due to his brilliant demonstration of how an engineer/scientist thinks during the Rogers Commission hearings on TV.
What happend during the Challenger explosion?
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. It was believed that the crew survived the initial breakup but that loss of cabin pressure rendered them unconscious within seconds, since they did not wear pressure suits.
What caused the Challenger accident?
The commission found that the Challenger accident was caused by a failure in the O-rings sealing the aft field joint on the right solid rocket booster, causing pressurized hot gases and eventually flame to “blow by” the O-ring and contact the adjacent external tank, causing structural failure.
