"It's inevitable," abandoned space junk will explode into each other

“There is so much debris that it is colliding with itself and creating more debris, a catastrophic avalanche of collisions, which could rapidly destroy all the satellites in orbit; this is now possible, ”said Dr. Ben Greene, CEO of the Space Environment Research Center (SERC), according to the ABC report.

At the meeting, there was talk of at least 170 million pieces of debris in orbit, the remains of satellites or parts of other spacecraft, traveling at about 27,000 km / hour, which makes a millimeter piece behave like a projectile. of potential danger.

“A 5-millimeter piece of debris is a major threat to satellites and other infrastructure in space. Considerable damage occurs every year, ”says SERC, whose organization has been working on a space debris management project.

Professor Moribah Jah, an expert in space debris at the University of Texas, highlighted in turn that "the threat grows every day as it becomes easier for companies to launch objects into orbit," according to ABC.

"The availability of drones in the hands of the people has exceeded the government's ability to really regulate these things," said the academic.

To which he sentenced: "I think we are certainly on the path of what I call a community tragedy." According to the expert, without an action, a catastrophic collision was "inevitable."

At the Canberra meeting it was said that "it is a question of when, and not whether, such a dire event will take place," according to News.

Experts from the MT Stromblo Observatory in Australia added that the lack of data on how the millions of pieces of circulating garbage are moving in space is a big problem.

This means that not only the investment of 900,000 million dollars in satellites and circulating space infrastructure are in danger, but the services they provide: communications, television, GPS, etc.

Whose fault is it? Of the same satellites, and other space missions. The ships explode from the remaining fuel after being abandoned by their owners. They catch fire and a single large piece of space junk turns into thousands of smaller pieces.

At the meeting, they talked about looking for some type of regulation, however it is not known which space mission will take the first step in it, not to leave its waste to the community.

According to previous NASA reports, there is debris from non-functional spacecraft (including satellites), from abandoned parts of launch vehicles, eg satellite launches, debris disposed of during missions, and fragmentation debris.

In 1996, for example, a French satellite was hit and damaged by the remains of a French rocket that exploded a decade earlier.

On February 10, 2009, an abandoned Russian satellite collided and destroyed a functioning American commercial Iridium satellite. According to NASA, the collision added more than 2,000 pieces of debris to the inventory of traceable space debris. "

Then there is the case of "China's anti-satellite test, in 2007, when it used a missile to destroy an old meteorological satellite, adding more than 3,000 pieces to the debris problem."

However "only 30,000 of the 300,000 pieces of debris in orbit that are larger than 5 mm can currently be monitored", highlights the SERC.
