Astronauts in danger.

Therefore, once word of an impending electron storm is received, astronauts will be able to retreat back to the spacecraft if they happen to be in the middle of a spacewalk.

One of the highest risks when traveling to space is the threat from solar radiation. An explosion of particles and radiation coming from the sun could seriously damage the spacecraft and endanger the astronauts in their mission in space. NASA researchers think that with the help of the Solar and Heliospheric Observatory (SOHO) spacecraft, they will be able to send warning signals to astronauts before the severe storm endangers their lives.
Soho's mission is to study the surface of the sun, but since the spacecraft is equipped with a COSTEP (Comprehensive Suprathermal and Energetic Particle Analyzer) sensor that detects the number of particles coming from the sun and measures their strength, the researchers will be able to predict the approaching storm.
One of the most important particles is the electron, the first wave that arrives at the beginning of the storm and does not pose an immediate danger. The electron is the lightest particle among the other particles which are much heavier and more dangerous. After analyzing hundreds of storms in space, researchers were able to match electrons with an expected ion density prediction.
When the Soho spacecraft encounters an electron storm, the astronauts in space will also encounter it, the danger will materialize when ions and heavy particles arrive next. Therefore, as soon as news of an approaching electron storm is received, astronauts will be able to retreat back to the spacecraft and steer themselves to safety, while suffering minimal damage if the storm catches them during a spacewalk.
This technique was able to predict four huge storms in 2003, while sending warning signals in a time frame of 7 to 74 minutes.

  1. "The face of the sun" and not "the ground face of the sun." The sun has no ground.

  2. Wow!!! Giant!

    you are welcome! please!

    Give more information…

    In any case, thanks!
