SpaceX says that 40 artificial satellites of the satellite Internet ' Starlink ' developed by space development company SpaceX may re-enter the atmosphere of the earth because they did not enter normal orbit due to the influence of magnetic storms at the time of launch. I announced it.

SpaceX launched 49 Starlink satellites into low earth orbit using the commercial launch vehicle Falcon 9 from the Kennedy Space Center in Florida at 13:13 local time on February 3, 2022.

The Starlink satellite is deployed in an orbit lower than the operating orbit, and then the satellite is raised to a normal orbit. This is to prevent the system from creating space debris that affects other satellites by leaving the orbit when a satellite that does not operate normally is discovered. SpaceX said, 'Because of the low altitude, we need higher performance satellites and it costs a lot, but I think this is the right thing to do to maintain a sustainable space environment.' I am.

SpaceX said in an official statement that the Starlink satellite launched this time was affected by the geomagnetic storm that occurred on February 4. The magnetic storm causes the temperature and density of the atmosphere to increase, and it is said that the drag of the atmosphere increased by 50% in this magnetic storm.

SpaceX changed the flight position of the Starlink satellite to minimize the effects of magnetic storms, and worked to collect and provide information in collaboration with the US Space Force and Leo Labs , which provides artificial satellite mapping services. As a result, 'preliminary analysis shows that increased resistance at low altitudes prevented satellites from leaving safe mode and orbiting, and up to 40 satellites re-entered or already re-entered the Earth's atmosphere. It turned out to be a rush, 'SpaceX said.

There is no risk of the Starlink satellite, which was not successfully launched this time, colliding with other satellites, and because it is designed to burn out when entering the atmosphere, there is no risk of new space debris being generated or debris pouring onto the earth. ... apparently ...
