” The hole was made in 2021, where a 1 mm things, traveling at over 25,000 km/h relative to the Space Station struck the robotic arm. No critical components were damaged,” said Mogensen on social media.
The effect punched through the arms thermal blanket and impacted the boom. The robotic arm, which has actually been in service on the ISS for over twenty years, continues to function normally.
The ISS isnt constantly so fortunate. In October, the Nauka science module suffered damage from a comparable micrometeorite impact, triggering 72 litres of coolant to leakage from the modules radiator out into area. After figuring out that the dripping coolant may contaminate astronauts spacesuits, a spacewalk planned for October 12th was delayed. Mogensen, alongside NASA astronaut Loral OHara, was scheduled to recuperate science samples from the station exterior, where tests are ongoing to measure the capability of resistant microbial life to make it through in area. In addition, the pair were expected to carry out a variety of outside upkeep activities, consisting of camera replacements and jumper cable installations.
That spacewalk will now take place in January or February 2024.
Canadarm with a micrometeorite impact: ESA/NASA-A. Mogensen.
In its decades-long history, the ISS has so far prevented any serious damage to its pressurized modules. The station has the capability to steer itself out of harms method in the case of a close approach with a known piece of space debris. These incredibly elusive actions have actually happened regularly throughout the ISSs operations, taking place at a cadence of one or two times annually (and thrice in more recent years).
When debris may be on an accident course, the difficulty is knowing.
Ground-based orbital particles tracking programs presently monitor about 33,000 pieces of recognized area particles. But smaller pieces of debris and micrometeorites can not be tracked from Earth, so the station depends on protecting to protect itself. A multi-layered structure referred to as Whipple shielding distributes the force of effect over a broader area, avoiding depressurization.
There are likewise innovation demonstration tests in the works for on-orbit debris trackers, which will have the ability to discover much smaller sized pieces of particles (as small as 3 cm).
In the meantime, astronauts like Mogensen stay prepared for the worst-case scenario. A carefully planned routine of emergency situation procedures is one way that area firms attempt to reduce the dangers.
” Most of the modules have protecting versus smaller sized impacts, but it is not strong enough to endure impacts against larger ones,” states Mogensen. “This is why we repeatedly practice emergency situations, including depressurization.”
Mogensen will remain in orbit up until February 2024, when he will go back to Earth with four of his crewmates on a SpaceX Dragon capsule. This is Mogensens second objective in space.

Living in area includes threats. For astronauts on the International Space Station (ISS), those threats sometimes make themselves intrusively obvious.
Previously this month, European Space Agency astronaut Andreas Mogensen snapped an image of the Canadarm2, in which damage from a micrometeorite effect is clearly visible.
In October, the Nauka science module suffered damage from a similar micrometeorite effect, causing 72 litres of coolant to leakage from the modules radiator out into space. Mogensen, along with NASA astronaut Loral OHara, was scheduled to recuperate science samples from the station outside, where tests are continuous to measure the capability of resilient microbial life to make it through in space. The station has the ability to navigate itself out of damages way in the case of a close method with a recognized piece of area debris. Ground-based orbital debris tracking programs currently keep track of about 33,000 pieces of recognized space particles. Smaller sized pieces of debris and micrometeorites can not be tracked from Earth, so the station relies on protecting to secure itself.
