Clarification requested. Isn’t the magnetic field of Mars so weak that a stay of just a few days would be dangerous?
How do the lunar and Martian environments compare, as regards the solar wind? Does the fact that people have been on the moon imply it’s safe to spend time on Mars? What little I could understand of the information I found tells me that the moon has some variable magnetic protection from the solar wind, but I could not come to any conclusion that helped me understand the Martian situation.
Too, I don’t understand the mention of escape velocity regarding the approach of the lander to the planet. Yes, the craft was going very fast and had to slow down, but…. ?? Isn’t the significance of escape velocity entirely a matter of trajectory, that is, of intent?
