Fast science and technology news on December 1, according to CCTV news, according to the China Meteorological Administration Space Weather Center monitoring, December 1, 2, China may have geomagnetic storm activities.

Among them, more than moderate geomagnetic storms or even geomagnetic storms may occur on December 1, and geomagnetic activity is expected to continue until December 2.

Under this influenceThe altitude of the orbit of the space station may decrease due to atmospheric towing, and the error of satellite navigation equipment may increase, and aviation flight will face the dual risks of deteriorating communication environment and trans-polar radiation.For the public, especially homing pigeon players and auroral enthusiasts, you should always pay attention to space weather information in the next few days.

It is reported that geomagnetic storms are caused by the influx of solar wind (charged particles from the sun) into the Earth's magnetic field and the production of charged particles and currents in the Earth's upper atmosphere.

The surge of solar wind will warm the upper atmosphere and further increase the atmospheric density.As a result, the resistance to satellites in lower Earth orbit will increase sharply enough to cause them & ldquo; to tumble and rdquo; to return to Earth.

In February last year, of the 49 chain satellites launched by Musk's SpaceX company on February 3, 40 were unable to deploy their orbits correctly due to geomagnetic storms, resulting in the scrapping of ldquo; & rdquo;.

SpaceX said the geomagnetic storm created 50% more resistance than in the past, and although the company tried to make an edge detour to avoid it as much as possible, 40 of them were expected to burn up in the atmosphere.
