From swissinfo.ch:

Space junk: a Swiss warning to the world

Marc-André-Miserez
8 February 2022

On November 15 last year, some 480 kilometres above the vast
Russian steppes, the satellite Kosmos-1408 exploded in silence,
disintegrating into a cloud of debris of various sizes. Retired
from service 40 years ago, the spacecraft had just been hit by an
A-235 antiballistic missile, fired from the Plesetsk Cosmodrome.

Four hundred and eighty kilometres – that's dangerously close to
the orbit of the International Space Station (ISS). The seven
crew members were immediately told to put on their space suits
and take shelter in the emergency capsules which would bring them
back to Earth if there was a collision.

At the Pentagon, Russia's action was denounced as "reckless" and
"dangerous and irresponsible". Moscow responded that everything
had conformed with safety rules. After all, there are two Russian
cosmonauts on the ISS, one of whom is the commanding officer.

Collisions in space

This space shoot'em up was not the first of its kind. China in
2007, the US in 2008 and India in 2019 had already put on such a
show of force – always on one of their own satellites.

There have also been accidental collisions. On March 22, 2021,
the Chinese weather satellite Yunhai 1-02 struck a piece of a
Russian Zenit-2 rocket launched in the 1990s. That was the worst
orbital collision documented since 2009, when the Russian
military satellite Kosmos-2251 hit Iridium 33, an American
communications satellite.

Each of these incidents, whether intended or not, added several
hundred bits of debris to what is already present in the low
Earth orbit range (up to 2,000km altitude). There are already
34,000 pieces of space junk, counting only those that ground
radar systems can detect. There are also around 130 million small
bits of debris orbiting at 20 times the speed of a rifle bullet
which are also likely to cause considerable damage on impact.

Ideas for a solution

Today, space agencies and private-sector satellite launch
companies as well as the research world are very much aware of
the problem. Scientists at the Swiss Federal Institute of
Technology Lausanne (EPFL) have been working on it since at least
2012, when the ClearSpace project was initiated. This is a
project to develop the first satellite that can actually pick up
space junk.

However, decision-makers have not been convinced of the value of
investing in such waste management solutions. Marie-Valentine
Florin, director of EPFL's International Risk Governance Centre,
pointed out to Muriel Richard-Noca, co-founder of ClearSpace,
that there was no comparative study of the various solutions and
the costs involved.

This task went to Romain Buchs, a young physicist who had just
completed a Masters thesis studying the issue of waste management
in space. An initial report came out in spring 2021, and at the
end of November a set of options for political and industrial
decision-makers was added.

"We targeted this paper at about 400 people in the space agencies
and the private sector," Buchs says, conceding that "it is
difficult to reach the Chinese and the Russians" and that
military leaders are not on the list.

"Normally these satellites are supposed to re-enter the
atmosphere [and burn up] 25 years after their operating cycle is
completed, at the latest. But the rule is not binding and it's
often ignored. About 60% of satellites follow the rule, though it
should be at least 90%," he says.

Small and large fry in orbit

Meanwhile, more and more satellites are out there. And for
several years states have no longer had a monopoly on access to
space. The trend has been for low-orbit satellite constellations.
This began at the end of the 20th century with Iridium and
Globalstar for satellite telephone communications. But there were
barely 100 of these.

Following OneWeb, then Starlink (SpaceX) and Kuiper (Amazon),
satellites were now in the thousands, supposed to bring fast
internet access to the whole world. The operators promised to
take all necessary precautions, keeping their spacecraft flying
low enough for them to fall out of orbit automatically after a
few years, or else fitting them with devices to facilitate their
capture by future space pick-up craft.

For Buchs, these clouds of small satellites are not really the
problem. "Basically, states have created the problem. The newer
satellite constellations are most likely to get hit. Those are
the little satellites, which weigh barely 150 kilos each. The
real problems come from whole rocket stages – above all Russian
ones – which may weigh up to nine tonnes each and which were
jettisoned between 1980 and 2005," he explains.

Getting a grip on the chaos

That said, Buchs doesn't believe in apocalyptic scenarios such as
the Kessler syndrome, which envisages near space becoming so
crowded that further flights would become impossible.

"We'll never be able to pick up all the small debris – we'll have
to concentrate on the big chunks, which may crash into one
another and shatter into thousands more little bits. There are
about 2,000 of them in low orbit. If we picked up just three or
four of them a year, it would reduce the risk considerably," he
says.

This is the goal of the ClearSpace project, which started at EPFL
and is now under the aegis of the European Space Agency. The
Japanese now have a similar project and there will be others.

Meanwhile, if anyone thinks it would be enough to declare a
moratorium on all new launches into orbit, they forget how much
our world depends on satellites.

"Just to take one example, 26 of the 55 parameters used for
measuring climate change can be calculated only from space,"
Buchs says.
