January 1 According to a report by the Russian Satellite Network on the 1st, Dmitry Rogozin, president of the Russian National Space Group, said that the cracks in the Russian service module of the International Space Station may be caused by micrometeorites or technical reasons.
Rogozin reportedly said: “On the International Space Station, it has indeed been found that some parts of the shell have been affected. This may be the impact of micrometeorites, which are very small.
That is to say, there are cracks and holes invisible to the naked eye.
( The reason) may be some kind of technical damage… It is not surprising.
Rogozin also said that people who caused panic with the crack of the International Space Station made a fusss.
In September 2019, the International Space Station detected a small amount of air leakage. From August to September 2020, the air leakage speed increased from 270 grams per 24 hours to 1.4 kilograms.
The astronauts on duty closed the hatches for sealed inspection twice and quarantined in the Russian module for several days.
The air leakage point was eventually locked in the transit compartment of the Russian Star service module, where a 4.5-centimeter-long crack was found in October. The astronauts tried many times to seal the cracks, but failed to completely stop the air leakage.
According to the report, Roscosmos Group said that the leakage point posed no danger to the International Space Station or the expedition team. Russian Space Group said earlier that in February 2021, after the next Progress cargo spacecraft brought a special repair kit to the International Space Station, it will completely block the cracks caused by the transhipment compartment of the Star service module.
