These 4 mistakes are small but have caused NASA to suffer a disaster, causing billions of losses

Life always has mistakes, and every mistake makes you lose something.

Every mistake has to cost, and the price will be very expensive when you work at NASA.

Life always has mistakes, and every mistake makes you lose something. But in places where the exact factor is first, there is no room for errors, because even the smallest mistakes can have serious consequences.

Knowing that, but NASA still has mistakes, and they pay hundreds of millions of dollars for that.

1. Explosion - wrong material

NASA experts used rubber gaskets - a cold-resistant material that caused the space shuttle Challenger to explode.

On January 28, 1986, the world was shocked to see NASA's Challenger shuttles explode in the Atlantic sky just 73 seconds after takeoff.

The entire crew consisted of 7 deaths immediately, estimated to cost up to $ 5.5 billion (about VND 113 trillion).

But why? According to later reports, it turned out that experts at NASA were too subjective. They use rubber gaskets - a cold-resistant material. So when the temperature dropped, the gasket broke, causing hot air leaks to directly blow into the fuel tank and cause the ship to explode.

2. The failure of Hubble Space Periscope

Hubble is a very famous NASA telescope. It is notoriously not due to historical achievements, but partly because of the expensive incident that happened earlier with this satellite in 1990.

After achieving a stable trajectory and being officially put into operation, Hubble frustrated researchers. The reason is because the images it sends are too blurry, can't be used.

A lot of specialists then joined, and finally found a way to fix it. It turned out that the design error caused the camera lens to be too flat, leading to a false phenomenon that caused blur.

Hubble is not broken, does not explode or stray, but the cost to repair it is not small. Estimated damage of the incident is 1.5 billion USD (about 34 thousand billion VND).

3. The accident of the Genesis - trot probe mounted 2 pieces of equipment

Genesis was created by NASA with a very noble mission: to bring samples from space to Earth for analysis. That ship is a hope that will help humankind understand more about the vast universe.

It seems that everything will go smoothly, because this is not a complicated task. But the probe stopped and fell in Utah, USA in 2004 - just three years after being launched into space.

Most specimens are destroyed in the collision. The latter reason was confirmed, that experts had installed two very small parts in the engine. That's all, and $ 260 million (about VND 6,000 billion) goes.

4. Satellite Mars strayed

Programming errors cause stray Mars Climate Orbiter.

To investigate whether physical conditions on the Red planet are suitable for humans, NASA designed the Mars Climate Orbiter - a satellite that collects Mars climate data and plans to bring It came into operation within 2 years.

Launched in December 1998, the satellite is expected to reach Mars about a year later. However, on September 23, 1999, NASA announced the Mars Climate Orbiter was officially missing.

The reason this time is because of programming. Some experts have forgotten . to change units to one system, leading to big errors in the system. And indeed, one wrong sentence, one mile is true in this case, because no one knows where it is now.

Estimated damage to this micro-bug is $ 125,000 (about VND 2.9 billion).
