WASHINGTON, Sept 23, 2020 (BSS/AFP) – Astronauts on the International
Space Station carried out an “avoidance maneuver” Tuesday to ensure they
would not be hit by a piece of debris, said US space agency NASA, urging
better management of objects in Earth’s orbit.
Russian and US flight controllers worked together during a two-and-a-half-
minute operation to adjust the station’s orbit and move further away,
avoiding collision.
The debris passed within about 1.4 kilometers (nearly one mile) of the
ISS, NASA said.
The three crew members — two Russians and an American — relocated to be
near their Soyuz spacecraft as the maneuver began so they could evacuate if
necessary, NASA said, adding that the precaution was taken “out of an
abundance of caution.”
The astronauts were able to return to their normal activities after the
procedure, according to NASA.
“Maneuver Burn complete. The astronauts are coming out of safe haven,”
NASA chief Jim Bridenstine said on Twitter.
The threatening scrap was actually a piece of a 2018 Japanese rocket,
astronomer Jonathan McDowell said on Twitter. The rocket broke up into 77
different pieces last year.
The ISS usually orbits roughly 260 miles (420 kilometers) above the Earth,
at a speed of about 17,000 miles per hour.
At such a velocity, even a small object could seriously damage a solar
panel or other facet of the station.
This type of maneuver is necessary on a regular basis. NASA said 25 such
maneuvers had occurred between 1999 and 2018.
Bridenstine wrote on Twitter that this was the third such maneuver on the
ISS just this year.
The operations could become even more frequent as Earth’s orbit becomes
littered with pieces of satellites, rockets and other objects launched into
space over the last sixty years.
Accidental or deliberate collisions, including anti-satellite missile
launches by India in 2019 and China in 2007, can break objects apart even
further and create added risk.
“Debris is getting worse! Time for Congress to provide @CommerceGov with
the $15 mil requested by @POTUS for the Office of Space Commerce,”
Bridenstine tweeted.
The Office of Space Commerce is a civilian organization that supporters
want to take over the surveillance of space junk, a job currently occupied by
the military.
