Shortly after launching 49 Starlink satellites, SpaceX Corporation went “weakened” when all of those satellites fell out of orbit and burst into flames. Recently, NASA revealed the cause of this serious incident.
“Death” of 49 satellites
On February 3, 2022, SpaceX launched a beam of 49 Starlink satellites to an altitude of just 210 km above the Earth’s surface.
However, they do not last long. After that, everything burned and fell to the ground. The loss of the Starlink satellite cost SpaceX millions of dollars.
A team of researchers from NASA’s Goddard Space Flight Center and the Catholic University of America took a close look at the causes of this disaster.

Their analysis identified a plasma mass of the Sun impacted by the Earth’s magnetosphere. This mass of plasma is moving away from the Sun at a speed of about 690 km/s in the form of a magnetic shock cloud.
As this mass moved, satellites returning to the Sun, including the astronomical observatory TEREO-A, were directly affected by it.
As the team explains, when the Sun is active, it can cause a phenomenon called solar flares. “Space weather”. Now an area called “thermal layer” Being shot at. This increases the density of the upper atmosphere for a short time and causes it to swell.
Essentially, the thicker atmosphere slows everything down and heats things up as well.
Meeting atmospheric resistance, the Starlink satellites fell out of orbit and caught fire on their way down.
SpaceX reportedly decided to launch the satellite anyway despite warnings from space weather experts about the impact of a geomagnetic storm.
Threat of the Sun
The sun continually sends out streams of charged particles called solar wind In the universe. These flows vary in density, speed and temperature.
The Sun also occasionally spits out a mass of lasers in a phenomenon known asto “coronal mass exaggeration”. Sometimes it also emits solar flares.
During times of greatest solar activity, plasma clouds can appear quite frequently.
If they impact the Earth, depending on the magnitude, they will create spectacular auroras, disrupt the operation of commercial satellites or cause blackouts on the ground…
Currently, the Sun’s activity increases as it enters a period called “the maximum of the Sun”. This means that communications and other satellites are in danger. The astronauts of the International Space Station too.
Not only in space, power grids, communication lines and other technologies on Earth are also under threat.
