The James Webb Telescope will surely hit space debris, and repairs are not possible

An important space observatory in the form of the James Webb Space Telescope, What we got into the universe during the Christmas holidaysYou will bump into space debris during the process, reach futurism. During its live broadcast NASA warned And it’s a slightly different space from what we know.

This is not a disaster

Due to its location and its large distance from Earth, which is more than 1 million km, the telescope does not risk exposure to space debris produced by humans, particularly affecting the lower orbits of the Earth. However, it is much worse due to the meteorites that are filled with the solar system and the smallest of them cannot be observed at all.

“There will be some small collisions with micro-meteoroids. You know, there will be some damage to the telescope mirrors during the life of the mission.” said Michael Thaler, a scientist at NASA’s Goddard Space Flight Center.

if but Explain inverse, such damage to the mirrors does not mean the end of the job. For example, the Hubble Space Telescope has faced similar problems, and its ability to take stunning and scientifically important images of the universe has not been seriously affected.

Expect damage

When scientists designed and built this majestic monitoring device, they also included potential collisions with micrometeorites in their life expectancy calculation. In addition, its life span has been significantly increased thanks to the European Ariane 5 missile, Reports to Ars Technica.

It brought it into orbit with such precision that it has a life span of at least 20 years when it comes to orbiting fuel. According to the original plan, it was supposed to last at least 10 years. Prior to launch, the telescope had 240 liters of hydrazine (rocket fuel) at its disposal, and it missed adjusting its trajectory and velocity to a much smaller degree than NASA expected.

But while JWST is protected from space debris of human origin due to its distance from Earth, most other satellites or even astronauts can’t say the same, even to a large extent.

The United States is late in cleaning up the orbit

outlet space news indicate to orbital cleaning problems, as a number of active satellites threaten space debris. According to experts, the United States lags far behind in solving this problem, adding that giant satellite groups such as Starlink, whose services arrived in Slovakia a few days agoOr OneWeb or many others that companies are still planning.

According to them, the real threat is already represented by destroyed objects, debris and fragments of satellites. These occur, for example, by the collision or failure of old satellites or even anti-satellite weapons tests, such as Russia and Thus, it threatens not only a number of active satellites but also astronauts On the International Space Station.

who – which

“Let me tell you, the United States lags behind the rest of the world. It is embarrassing to me to hear people talk about the need for an efficient system for the disposal and control of space waste, as if it were something decades later.” Darren McKnight of LeoLabs, a California Low Earth Orbit (LEO) monitoring company, said concerned.
