With each successful launch by companies such as SpaceX and Virgin Galactic (SPCE), the commercialization and industrialization of space has become increasingly inevitable, and space debris or space debris is becoming a growing concern for companies and government aerospace entities. .
The European Space Agency (ESA) estimates that there are currently 29,000 objects larger than 10 cm in Earth orbit, 670,000 objects larger than 1 cm and more than 170 million objects larger than 1 mm. Space debris includes man-made objects, such as materials left over from space missions, as well as natural objects such as meteoroids. Problems can arise because space debris can be difficult or even impossible to track depending on its size, and collisions with manned or unmanned spacecraft can bring bad luck to missions or ship missions.
“There is traffic management for cars, ships and airplanes, but not space traffic management,” Astroscale CEO and founder Nobu Okada told Yahoo Finance Live. “[In this way] now the density of space debris has reached a critical level, and there may be a chain reaction of collisions in the near future. Therefore, we have been discussing with many governments [to seek solutions]. ”
Astroscale was established in 2013, It is a private orbital debris removal company based in Tokyo, Japan, and describes itself as “the first company with a vision to ensure the safety and sustainable development of space for the benefit of future generations.” The company signed an agreement worth US$3.4 million in May. An agreement with OneWeb to develop space debris removal technology. Okada joined the Yahoo Finance Live to discuss the growing impact of attention to space debris and how Astroscale solves the problem.

According to Okada, the technology of space debris processing revolves around the use of satellites, which capture debris in orbit, stabilize it, and then send it back Earth’s atmosphere. Place of cremation upon re-entry. He said that fragments can orbit the earth at a speed of 7 to 8 kilometers per second, which is 10 times faster than a bullet.
Currently, satellites can only capture one piece of space junk at a time. Okada said Astroscale is currently developing a satellite that can capture multiple debris at the same time.
“We just developed the world’s first demonstration satellite and now it’s in space,” Okada said. “So we will show demos soon.”

Talks between world leaders at the G7 summit in 2021 are about space debris A critical step in reaching a consensus on the crisis, according to Okada. Representatives from Canada, France, Germany, Italy, Japan, the United States, the United Kingdom, and the European Union agreed to make this issue a priority to ensure the sustainability of the use of space.
Okada also stressed the importance of removing large chunks of space debris as soon as possible, saying the threat of a “chain reaction” of space debris collisions, also known as Kessler syndrome, is imminent.
“There are so many near misses every day, and the probability of a collision is very low,” said Okada. “However, more than 30,000 objects orbit the Earth 16 times a day. So, [eventually] they collided with each other, and now they broke several times. So if we don’t take action, the debris will continue to collide with each other and become small particles. The satellite cannot be placed anywhere. ”
