January 28, 1986 NASA, ROCKET DISASTER

NASA has been carrying out highly reliable and successful work since January 28, 1986.
With the Mercury mission, the first American was sent to space, with the Gemini missions, an astronaut was the first to survive while suspended in space, and for the first time, two different spacecraft were connected to each other, making a serious difference in the Space wars with Soviet Russia. With the Skylap project, America was the first spacecraft to orbit the earth. Later, this station became the international space station.
With the Viking program, the first spacecraft was landed on the planet Mars, and with the Voyager programs, vehicles that would go out of the solar system were made functional. In this way, NASA achieved many successes one after another, widening the technological gap between it and Soviet Russia. NASA's budget has decreased over the years, thanks to the US governments realizing that Soviet Russia could not catch up with them.
With the Space Shuttle program, space shuttles will be taken to space for experiments of institutions that want to conduct research in space, and NASA aims to fund space projects with the income generated.
The rockets used at that time could not be used by returning them. They focused on this issue to reduce costs. The spacecraft built consists of 3 shuttles and 1 orange tank. The tank only provides fuel. Only the fuel tank of the vehicle launched into space was destroyed by burning. There are two different rocket groups connected to the fuel tank. The first of these is the solid rocket boosters attached to both sides of the fuel tank. These are the main thrusters that lift the shuttle in the first 2 minutes after takeoff. When their mission is completed, they can be lowered to the ground with the help of parachutes and used again. The 2nd group of rockets are the main thrust rockets of the shuttle. This 2nd group of rockets provides the necessary power and maneuverability to reach space after takeoff.
It was used to establish space telescopes and observatories as the basis of space shuttle missions. The necessary parts for the space station installation were taken to space in this way. Despite all these developments, sending vehicles to space continues to be a very expensive business. In order for all these operations to be profitable, NASA has to space space every 6 days. However, NASA could only make 9 flights in a year. This situation left the institution in a financial difficult situation, and every employee of the institution, from managers to employees, had to bow to this cost pressure.
In 1986, Roger, who was working at one of the subcontractor companies he worked with, detected a fault in the reused rockets. It turned out that there was a problem in the systems that prevent fuel leakage. An attempt was made to improve it, but it was not successful. For this reason, NASA, under the pressure of capitalism, changed the flight procedure and ignored small errors. They chose to come.
For the 10th flight of the Challenger flight on January 28, 1986, NASA added the transportation of civilian personnel to the flight plan for the first time. As the temperatures dropped to -7 degrees the night before the launch, everything on the launch platform froze. Although this was not a suitable environment for the flight, the launch was postponed 6 times before. They did not postpone the flight. In this case, the engineers did not give the approval signature required for the flight to take place. However, NASA took the authority and carried out the flight.
When the Challenger rocket started to take off, there was no problem for 1 minute. However, due to the malfunction in the warnings made by the engineers, fuel leaks began to occur and the burning in the leakage area brought the rocket to the explosion level within half a second. The explosion occurred and the entire crew died due to a rushed spacecraft.
After the Challenger disaster, the Rodgers Commission, consisting of important astronauts, was established and research was carried out. NASA developed new measures after this disaster. First of all, solid fuel thrusters were redesigned. Technical corrections were made to avoid the same problems during launch operations in cold weather. After all these events, NASA had to wait 2 years for the launch again.
