'Robot' floats in space trash

Space debris spinning in orbit outside the Earth's atmosphere has accumulated since the launch of the first satellite in 1957.

If you think about a failed projectile, it's a huge amount, but the exact amount is not known. The foreign press speculates that about 750,000 debris and more than 3500 closed satellites will be floating.

Since the universe is wide and wide, some people think that there is no problem with garbage. But what if space debris collide with the International Space Station (ISS), spacecraft or astronauts? The flight speed is also faster than the bullet, which is really dangerous.

In fact, NASA scientist Donald J. Kessler foretold later that space orbits would make space exploration impossible and satellites unusable. This is called the Kessler effect.

The European Space Agency (ESA) has announced that it will launch a robot that collects garbage. The goal is to collect the remnants of Vespa, which was launched in 2013, by launching Clearspace-1 in orbit in 2025.

The sweeping satellite will use robotic arms to collect garbage, return to the atmosphere, burn and disappear. The Guardian also called the "suicide robot" because the satellite and the garbage disappeared together.

The news sounds welcome as private space companies, including SpaceX, are launching several satellites, including Internet satellites.

But experts also point out that current technologies that require one cleaning satellite per space debris can't remove massive space debris at once.

ESA officials say it is important to develop a clearing satellite, but it is also urgent to have regulations that allow the party or organization that launched the satellite to be responsible for its disposal.
