The Challenger Disaster

The challenger disaster, also known as the explosion that happened in the space shuttle orbiter named Challenger, was a very disastrous event that took place in Cape Canaveral, Florida. It was shortly after the launch of the shuttle on January 28, 1986, when it exploded and resulted in the death of about 7 astronauts who were in the shuttle during that time. The space shuttle challenger was meant to launch a satellite that was supposed to be used for tracking data and other aspects. 

The shuttle also was a carrier for the Spartan Halley spacecraft. This was another smaller satellite that was supposed to be released by the Challenger. However, this smaller satellite would have been picked up after making observations on Halley's comet after 2 days. 

The Explosion of Challenger Shuttle 

The greatest visibility was provided to teacher-in-space Christa McAuliffe who belong to New Hampshire. She was supposed to conduct about 2 different lessons from the orbit. Then she was spending the following 9 months providing lectures to the students regarding high-tech careers. Some other members of the space shuttle challenger crew were Judith Resnik, Ronald McNair, Ellison Onizuka, and other mission specialists as well.

It was during the outset when the mission was seemingly experiencing some sort of trouble. The launch was then postponed for some days. This was partly because there were certain delays taking place in getting the former mission of 61-C back on track. Not just that but on the day of the launch, January 28, the liftoff was also a bit delayed. 

Everything seemed to be normal when the vehicle would emerge from the Max-Q position. This was the position when the aerodynamic pressure of the vessel would be at maximum levels. This was when the mission control got the message that the Challenger shuttle was up with full throttle. It was just after some time, approximately 73 seconds of launch when the vessel had the explosion. The altitude at which the explosion took place was about 14,000 meters or 46, 000 feet in total. There were certain tapes that were salvaged from the entire wreckage that would show the entire episode of the explosion. Before the breakup of the tape, a crew member could be heard saying “Uh-oh” and then nothing else was heard. The debris from the vessel poured down into the Ocean for about an hour or more after the entire explosion took place. There was no sign left from the crew and it was concluded that the entire crew was killed along with the explosion. 

The Space Shuttle Challenger Disaster: The Aftermath 

This was an incident that would immediately ground the entire shuttle program. There was some extensive investigation that took place by the National Aeronautics and Space Administration. Also, the U.S President at that time Ronald Reagan appointed a commission for the investigation of the entire incident. Some of the members of the commission were Sally Ride, Chuck Yeager, Neil Armstrong, and William Rogers who was the former secretary of the state. Richard Feynman was appointed as the physicist for the entire operation. 

The end result for the entire commission was a very appalling pattern of certain assumptions that were made regarding the explosion of the vessel. It was speculated that the vehicle was sturdy enough to go through certain small mishaps and would have survived even further problems. Furthermore, this was the ill-fated and unlucky launch that led to increase the difficulties for NASA who had been going through a tough phase for a very long time. It became even more difficult for NASA to get back up after so many years of trying to accomplish certain goals without having the right budget for it. 

What Caused The Space Shuttle Challenger To Explode? 

It was after a few days of the explosion that the actual and immediate cause for the explosion was suspected and found. The full establishment of the cause happened just after a few weeks of that. It was said that the cold wave the night before could have had a role to play in the explosion of the space shuttle challenger. The cold might have reduced the entire resiliency of the different O-rings that were made of rubber. These rubbers were responsible for joining the 2 different lower segments of the rocket booster situated on the right-hand side of the vehicle. If the circumstances would have been normal, the 3 main engines reserved for the challenger shuttle would actually have ignited and pressed the entire vehicle in a forward direction. The boosters would have ignited and thus the vehicle swung back to the center. 

It was also seen that right in the morning when the launch was supposed to happen, the Joint Rotation Effect occurred. This prevented the entire resealing of the rings and hence opened a bigger path for the exhaust gas to make an escape and thus led to the explosion. 

The Challenger disaster was a very significant event for NASA because during that time the space organization was going through a lot due to the constant failure of missions.
