What would happen if a satellite took a direct hit from a coronal mass ejection (CME)?

I was wondering what would happen if the average satellite were hit by an average CME. According to wikipedia the average velocity of a CME is 20 to 3,200 km/s. In addition to this it's super-heated, ...

What is the probability that a deep space crew is hit by a Solar proton storm?

The Sun's magnetic field now and then accelerates a gigantic amount of high velocity protons in different directions. Regardless of the types and causes, let's call it "proton storm" when it is ...

How would Solar Flares affect Solar Sail navigation?

As I understand, Solar Sail runs on dual energy: light pressure and solar wind. While the former is quite deterministic and rigidly following calculations, solar flares create huge bursts of solar ...
