7 Failure of the Most Expensive Space Mission History
January 8, 2018
One of the great desires of human is being able to explore outer space. Not only to the moon, human journey beyond the earth also continues to be perfected with the creation of many cutting-edge vehicles by scientists from various parts of the world.
However, many exploratory missions have to fail before they can successfully set foot in space. Not a bit, the failure of this mission also leads to huge losses that must be borne by the government.
The following 7 most expensive space missions in history reported by Business Insider on Thursday (4/1/2018)
- Columbia shuttle exploded – 2003
Losses: US $ 16.2 billion
February 1, 2003 became a tragic end to space missions with the space shuttle Columbia. The US space vehicle exploded in the air 16 minutes before landing, as it was about to step on Earth at Kennedy Space Station Center, Florida, USA. Seven astronauts of Columbia crew are confirmed dead.
Officials of the National Aeronautics of America (NASA) said the accident occurred when the 1981-made aircraft was at an altitude of 60 thousand feet from the earth at a speed of 20 thousand kilometers / hour. Before it exploded, the plane had just completed its 28th mission, after taking off on January 16, 2003.
The Columbia plane crash was caused by a piece of foam the size of a bag that crashed into the wing of the plane and left a hole in the protective tile, leaving the plane vulnerable as it pierced the atmosphere.
- The destruction of United States Challenger rocket – 1986
Losses: US $ 11.5 billion
Only 73 seconds after its launch on January 28, 1986, the American Challenger spacecraft exploded in the air. The tragic accident killed the seven crew members instantly.
The abnormally cold temperatures combined with the wrong equipment were the cause of the tragic explosion.
- Failure of missile launch missions and Soviet space station – 1973
Losses: US $ 3.61 billion
A rocket carrying robotic moon explorers crashed in the Pacific Ocean in 1973. This incident was only one month after the damage that struck the Soviet Union space station Salyut.
- Satellite telescope carriers destroyed in Earth’s atmosphere – 1970
Losses: US $ 581 million
In 1970, the United States launched The Orbiting Astronomical Observatory which carries the largest telescope in the world. Unfortunately the 12-foot protective rocket cone does not work properly. This resulted in the satellite not successfully penetrating the earth’s atmosphere.
- NASA’s weather satellite failed to reach orbit – 2011
Losses: US $ 431 million
The mission of the launch of NASA’s Glory satellite was declared a failure after the Taurus XL rocket that brought it failed to place it into orbit. This is because the protective cover of the top of the rocket is not released as planned at the time of three minutes after launch.
- South Korean satellite burns in the atmosphere – 2009
Loss: US $ 411 million
A satellite that became the first South Korean space rocket (South Korea) burned in Earth’s atmosphere after it failed to orbit.
According to South Korea’s Ministry of Science and Technology, the failure caused one of two rocket aerodynamic shoot covers failed to reach altitude after opening in preparation for satellite release.
This resulted in the weight of the second rocket shooter not enough to reach the place where the satellite should orbit. The speed dropped to a figure of 6.2 kilometers per second from an optimum speed of 8 kilometers per second.
- Russian communications satellites lost in space – 2011
Losses: US $ 305 million
A Russian Proton rocket launched in August 2011 with an AM4 communications satellite. Unfortunately, after entering the orbit the satellite is off the track and lost within 24 hours.
Monitoring station at the time noted, the incident occurred because the rocket was off track and too far away from the earth’s atmosphere.
