America - Japan cooperates to monitor pillar garbage

The Japanese newspaper recently reported that Japan and the United States have agreed to share data on space junk, and use radar to enhance the monitoring of these debris, preventing them from colliding. satellites and other objects.

There are more than 500 thousand cosmic garbage mentioned in the agreement between the two (including the no longer used satellites and its fragments). These rubbish pose a risk of insecurity to employees on the international space station and satellites on orbit.

Space junk flew in orbit around the earth at a speed of 8 km / sec, whenever it could hit meteorological satellites, satellite satellites and positioning satellites.

Recently, the international space station had to evacuate staff many times due to being warned about the risk of colliding with cosmic garbage. Experts in space warn that the amount of cosmic garbage on earth orbit has reached alarming level.

The United States and Japan signed an agreement to jointly search for cosmic garbage, locate these "retired" satellites that could fall on the earth to ensure Earth's safety.

Japan is considering taking advantage of the military's radar and missile systems to accomplish this task, while providing the US with data on the pieces of cosmic trash collected by telescopes and radar. cross.

At present, the US is the leading country in space garbage monitoring. The US military keeps track of debris with a diameter of 10cm or more, and provides relevant data for countries around the world. But the United States could not detect the whereabouts of smaller debris, Japan was studying new techniques to detect such debris.

Japan and the United States both agreed to conduct international dialogues on the issue of minimizing these pieces of cosmic trash.
