One of the worst disasters in space history!
The United States spent $1.2 billion to develop the best space shuttle , "running" at a speed of 1,600 miles per hour. After 73 seconds, it exploded and disintegrated in the forked smoke and flames. 47 astronauts survived. After the disintegration of the plane, the wreckage was scattered everywhere.
This disaster occurred in 1986. As a developed country in the world, the United States successfully led the completion of the "Apollo Lunar Exploration Project" in the 1990s, and then began to develop space shuttles, hoping to gain more in the field of space exploration.
So, the " Challenger " developed by the United States spent a huge amount of US$1.2 billion to be launched into space at 11:38 am on January 28, 1986.
This is an extremely anticipated day. American people gathered in the square to cheer for the launch of airplanes. looks forward to witnessing the history.
There are a total of 7 astronauts and one special crew member on the space shuttle "Challenger" .
This special occupant is a female sociology teacher named Christa McAuliffe . This female teacher was selected from more than 10,000 teachers. As a representative of outstanding teachers in education and publicity, he is preparing to teach two space experience classes to more than 2.5 million primary and secondary school students in the United States and Canada through television in space, and participate in several scientific experiments on the space shuttle.
For this female teacher, she was extremely excited and excited that day. Her students burst into cheers when they saw the shuttle carrying their teachers on board, delighting their teachers.
"Challenger" was successfully launched, and it "runs" at a speed of 1,600 miles per hour. This speed made the American audience in the stands excited and cheered, and everyone was proud of this great invention . The commanders of the
Ground Launch Center are also looking forward to the Challenger breaking through faster speeds and successfully entering the set track.
Everything looks very smooth, and the Challenger is about to enter the set track.
This best space shuttle in the United States suddenly began to appear abnormal after fifty seconds of rising into the air. Some spectators on the ground found unknown black smoke coming out of the side of the solid booster on the right side of the rear of the space shuttle.
may be blinded by the joy of making history, or it may be confident that the best space shuttle for American astronauts cannot have problems.
Command Center did not pay attention to this wisp of unknown black smoke, but allowed the airplane to continue flying. until 52 seconds, the ground command center notified the commander to mention the aircraft's engine to full speed. At this time, the altitude of the aircraft was more than 10,000 meters above the ground, and the engine's fuel was burning very fast.
At this time, neither the ground control center nor the space shuttle data center showed any abnormalities. The captain of the space shuttle reported to the ground control center with an urgent mood that "the aircraft is moving forward at full speed."
Unexpectedly, after rose above the 73rd second after the Challenger rose, the aircraft's external fuel tank suddenly exploded, and the Challenger turned into a huge burning flame. What is terrifying is that losing control of the two solid-boosted rockets is where people gather.
In a critical moment, the officer in charge of safety in the space center can only choose to detonate the aircraft through a remote control device. Challenger disintegrated in the forked smoke and flames, and the plane's debris scattered everywhere with gravity, and all the debris did not completely scatter to the ground after 1 hour.
As the debris fell, all seven astronauts and a female teacher on the Challenger space shuttle were killed, and none of them survived!
The audience in the stands and millions of Americans saw the disaster happening through TV.
No one can believe that the best NASA aircraft developed by the United States has spent so much manpower and material resources to suddenly explode as soon as it was lifted into space!
and even, there are family and friends of the Challenger astronauts in the stands. This day that should have been proud of them turned into a tragedy.
This accident was even one of the worst disasters in space history at that time. After
, NASA investigated the accident. This accident also had a huge blow to NASA. Although NASA did not give up on the development of new aviation aircraft after the "Challenger" aviation aircraft explosion, although NASA did not give up on the development of new aviation aircraft, it did not send astronauts to continue exploring space for more than two consecutive years.
After many investigations and people familiar with the matter said that on the day of the launch of Challenger, the temperature of was as low as -2℃ and the launch pad was frozen.
This causes one of the O-type rubber seals in the "o-ring" of the two solid fuel rockets to fail due to low temperature deformation and hardening under low temperature conditions.
When ignition, the O-ring must expand in time, but the O-ring is already in an ineffective state. When the flame is coming out, the O-ring also emits intermittent wisps of black smoke. The reason why the space shuttle was successfully launched was because at the beginning, although the O-ring had deformed in low temperature weather, its sealing effect had not yet been completely invalid.
However, there has been a problem with the O-ring. After taking off, it encounters a strong airflow. The flame burning causes the O-ring of the main fuel compartment to fall off. The sealing of the O-ring completely fails, resulting in gas leakage and causing the tragic explosion of the space shuttle.
Someone insiders said that was originally an avoidable accident. On the day of the launch of the space shuttle, some people raised concerns that the launch of the low-temperature weather is extremely dangerous. The components of the aircraft are likely to change due to low temperatures. For the space shuttle, a slight change is very likely to cause a launch accident.
Some engineers also suggested that the last time the space shuttle was launched, there was an accident almost due to the failure of the O-ring.
Even 30 minutes before launch, the research center also reported that strong airflow appeared over the launch, which was extremely unfavorable for the launch of the space shuttle.
However, the US launch center did not care about this issue, and it can be said that it deliberately ignored this issue, but instead wanted the space shuttle to successfully launch and complete this fast and urgent space exploration.
This led to this space disaster, the space shuttle was destroyed, and the space personnel were sacrificed.
Although NASA decided to redevelop the shuttle, it has not sent new astronauts to space for more than two years.
But this was an aerospace accident that should not have happened at all.
Because NASA is eager for quick success and instant benefits , it deliberately ignores the launch details, which leads to the explosion of aviation aircraft and the sacrifice of astronauts. All the failure is their own consequences!
Although the development of a country's aviation industry is very important, the primary premise of is to ensure the safety of the lives of brave astronauts who contribute to the national aviation industry!
If a country's space history creation takes the life safety of astronauts as experimental products, then even if history is truly created, does have real meaning?
