An overview of the seven heroic deeds of the American Challenger

A total of seven astronauts participated in the space shuttle. They were: Captain Francis Scobie, forty-six; driver Michael Smith, forty; astronaut Judien Resnick, thirty-six; Ronald McNair, thirty-five; Allison, Onizuka, thirty-nine; Grigory Jervis, forty-one; Female teacher Christa McAuliffe, 37 years old.

The crash of the Challenger dealt a heavy blow to the U.S. space industry, and the shuttle ceased flying for the next three years. However, after learning the lessons of the Challenger, human exploration of space continues. Since the resumption of the space shuttle, 76 missions have been flown to date, including the formation of the International Space Station.

The astronauts of the Challenger are the pioneers of human spaceflight. Isn't it in the texts of junior high school?

This is the cause of the crash!

On January 28, 1986, at Cape Canaveral, Florida, USA, tragedy occurred after the Space Shuttle Challenger lifted off.

At 11:38 a.m. that day, the Challenger ignited from the launch pad. But 73 seconds after the shuttle lifted off, there was a sudden muffled sound in the air, and the Challenger burst into an orange fireball, and the debris flew away with flames and white smoke and fell into the Atlantic Ocean. The Challenger happened, and the world was shocked.

Seven astronauts died in the accident, including two female astronauts. One of the most striking was McAuliffe, a female teacher who took part in a space flight for the first time as a civilian. According to the report of the committee investigating the accident, it was the result of the failure of an O-ring seal.

This seal ring is located between the two lower-level parts of the solid rocket thruster on the right. The failed seal caused the red-hot gas to ignite the fuel in the external fuel tank. Due to the poor weather conditions and low temperature at the time of launch, the O-ring failed at low temperatures and an accident occurred.

Although some engineers warned against launching in cold weather on the eve of the launch, the warning was not heeded because the launch had been postponed five times.

The Challenger is the second space shuttle from the Kennedy Space Center. It is named after the British research ship Challenger, which sailed in the Atlantic and Pacific Oceans, and made great contributions to human spaceflight.

In July 1982, the Space Shuttle Challenger became a reusable U.S. spacecraft with the Belt of Hebei, successfully completing nine space missions. On January 28, 1986, the U.S. Space Shuttle Challenger carried seven astronauts on its 10th space shuttle flight. During the Challenger's 10 missions, it orbited 987 times and spent 69 days in space.
