RU: 28 января 1986 года - космический корабль «Челленджер» в самом начале миссии STS-51L взорвался на 73-й секунде полёта, что привело к гибели всех семерых членов экипажа. . EN: On January 28, 1986, the NASA Space Shuttle orbiter undertaking mission STS-51-L and the tenth flight of Space Shuttle Challenger (OV-099) broke apart 73 seconds into its flight, killing all seven crew members: five NASA astronauts, one payload specialist, and a civilian school teacher. The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39 a.m. EST (16:39 UTC). The disintegration of the vehicle began after a joint in its right solid rocket booster (SRB) failed at liftoff. The failure was caused by the failure of O-ring seals used in the joint that were not designed to handle the unusually cold conditions that existed at this launch. The seals' failure caused a breach in the SRB joint, allowing pressurized burning gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB aft field joint attachment hardware and external fuel tank. This led to the separation of the right-hand SRB's aft field joint attachment and the structural failure of the external tank. Aerodynamic forces broke up the orbiter. . #challenger #challengerdisaster #spaceshuttle #space #космос #челленджер #мылюбим80е #80shistory #история80х #astronauts #astronaut #космонавт https://www.instagram.com/p/B72oedcldO-/?igshid=1qvhcd7i84326

On this day 32 years ago, the world watched in horror as the Challenger exploded and killed everyone on board. RIP #challenger #challengerdisaster #space

IMC MEDIA NERWORK Major Malfunction: Revisiting Challenger

[penny4nasa]

“For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.” - Dr. Richard Feynman, Rogers Commission Report Appendix F (6 June 1986)

There are several disasters in the history of NASA spaceflight where the worst possible thing could happen, people died. Though all of them are equally bad in their result, the Challenger disaster is especially important to remember because it was a series of mistakes that could have been caught and prevented beforehand, but were not. The direct cause of the explosion of the shuttle was a design flaw in the O-rings in the solid rocket boosters (SRB), which at very cold temperatures (below 30 degrees F) did not expand to seal off the hot gasses inside the motor. The hot gasses escaped and compromised the structural integrity of the main fuel take, which failed and destroyed the entire craft 72 seconds after launch.

The design flaw was a known issue by engineers at Morton-Thiokol who tried to make the issue known before anything disastrous happened, but were silenced in fear of the company losing their contract with NASA. Additionally, management had a very different idea on the likelihood of a failure in the shuttle than the working engineers, based seemingly only on the idea that a manned spacecraft would by nature be safer because people were on it. Wishful thinking at best. Furthermore, NASA was under extreme pressure to meet flight schedules too optimistically assigned that led to slacking in safety procedures as well as not testing whether it was safe to launch in cold weather, which had never been done prior to the ill fated Challenger mission. As time went on and the shuttle did successful missions, people became complacent that possible risks were acceptable.

The aftermath of the Challenger disaster changed a lot about spaceflight, and while so many things went wrong and should have been done better, it is important to remember that good did come from this. The design flaw in the SRBs were fixed, and NASA became more cautious with the shuttle, making sure not to push to launch if there was any concern of reliability or failure. Though Challenger would not be the last Space Shuttle disaster, it would serve as a reminder of the risks of spaceflight, risks we can overcome if we are willing to acknowledge they exist.

Fears of such accidents may make some think NASA isn't worth the money put into it, but this is shortsighted. Without proper funding NASA cannot ensure it can safely do its job.
