The Challenger Explosion
According to the online site Wikipedia, “The Challenger Explosion occurred on January 28, 1986, when the Challenger (OV-099) broke apart 73 seconds into flight, killing the seven crew members on board.”
The crew consisted of :
Francis R. Scobee, Commander
Michael J. Smith, Pilot
Ronald McNair, Mission Specialist
Ellison Onizuka, Mission Specialist
Judith Resnik, Mission Specialist
Gregory Jarvis, Payload Specialist
Christa McAuliffe, Payload Specialist and Teacher from New Hampshire
Based on information from the authors at Think Reliability, “The space shuttle broke apart because gasses in the external fuel tank mixed, exploded and tore the space shuttle apart. The external fuel tank exploded after the right solid rocket booster came loose and ruptured the tank. Because a seal around the O-ring (a piece of the rocket boosters) failed.”
According to the television broadcast CNN, “Shortly after liftoff, the space shuttle's external fuel tank collapsed, causing what looked like an explosion, and the shuttle broke apart and fell approximately 46,000 feet to the Atlantic Ocean.”
After that the result was the death of the seven crew members aboard. The tragedy unfolded on live TV – and the audience watching was particularly young.
Based on the information from the writers at Space.com, “In the wake of what happened with Challenger, NASA made technical changes to the shuttle and also worked to change the culture of its workforce. The shuttle program resumed flights in 1988. … The Challenger explosion changed the space shuttle program in several ways.”
According to the information at Wikipedia, “The Columbia disaster occurred on February 1, 2003, when the Columbia (OV-102) disintegrated as it reentered the atmosphere, killing all seven crew members.”
The crew consisted of :
Rick Husband, Commander
William C. McCool, Pilot
Michael P. Anderson, Payload Commander
Kalpana Chawla, Mission Specialist
David M. Brown, Mission Specialist
Laurel Clark, Mission Specialist
Ilan Ramon, Mission Specialist
On January 28, 2021 it will be the 35th anniversary of the Challenger Explosion. The Challenger Explosion was a tragic event that is remembered by many who watched the live televised launch on that day 35 years ago.

I liked the way you organized the page. Also I have watched a movie about this and thought the movie was pretty good. Why did the seal around the O-ring fail?
ReplyDeleteCS SoccerCat The cause of the disaster was traced to an O-ring, a circular gasket that sealed the right rocket booster. This had failed due to the low temperature (31°F / -0.5°C) at launch time.
DeleteI never knew that 7 people died in that flight, how much money did they lose when they crashed like how much money did they spend on making the shuttle.
ReplyDeleteMR Skittle The Challenger costed the nation $3.2 Billion.
DeleteI really like the art that you did! I have heard about ths before but never knew the reason that it exploded was because the gases mixed. Do you know wht type of gases mixed?
ReplyDeleteTR Lemon, Thank you for the lovely comment. My drawing took 5 hours to perfect.
DeleteThe gases that mixed were liquid hydrogen and oxygen.
I barely knew anything about the challenger explosion until now. You have a very informative blog, and I liked how you put the names of the crew members and their jobs into you blog. What do you think might have happened if the Challenger hadn't exploded?
ReplyDeleteEM Bookworm I think that if the Challenger did not blow up we would not have safer precautions with NASA and we would not have schools named after Christa Mcauliffe.
DeleteThank you for the lovely comment.
