U.S. Challenger Details 5

The second space shuttle officially used by the United States. Originally, it was originally developed as a high-fidelity structural test article (hence the initial fuselage code STA-099), but after the Challenger completed its initial test mission, it was converted into an official orbiter vehicle (hence the code name OV-099), and the mission maiden flight was officially carried out on April 4, 1983. Unfortunately, on January 28, 1986, during its 10th space mission, codenamed STS-51-L, the Challenger failed due to the failure of an O-ring on the right solid-state rocket thruster, causing a chain reaction and 72 seconds after liftoff, ** disintegrating and crashing.

All seven astronauts on board were killed in the accident.

This paragraph is named. The U.S. space shuttle is named after the name of the early research ship, so the name Challenger is no exception, since the 1870s in the Atlantic and Pacific Ocean, the British naval research ship HMS Challenger, in addition to the name "Challenger", has also been used to name the Apollo 17 moon landing module.

On January 28, 1986, the second space shuttle "Challenger" of the United States was on its 10th flight, and more than 70 seconds after rising from the launch frame, the space shuttle worth $1.2 billion turned into pieces and crashed into the Atlantic Ocean, killing all seven crew members, causing the largest tragedy in the history of world spaceflight. This is the first major catastrophe in the air in the 25 manned space flights conducted by the United States. The "Challenger" shocked the whole United States, and Washington and other places flew their flags at half-mast to mourn.
