Why don't they shows us the earth with all the satellites orbiting around?
Who is they and what are you asking to see? We see pictures of satellites orbiting all the time. There is an app that shows you where they are, websites that do the same, I see them personally all the time. What, specifically, are you expectations?
Why is Nasa saying they need to figure out how to cross the Van Allen belt for their Mars mission? Didn't we figure this out back in the 60's?
They didn't, the "article" you linked to as "evidence" is, and I am going to be polite about this, shit written by morons willfully taking things out of context in order to support their fucknutter position.
