Do you believe that humans have travelled in space ... to the Moon, to the ISS? Why do you do it? Does it make you happy?
Do you believe that Arianespace can put satellites into geostationary orbit even though they can't carry enough fuel or figure out when and in what direction to fire the rocket engine to transfer from low earth orbit to geostationary orbit?
Arianespace using their rockets only sends things
one way up in the sky on behalf of outside clients. It is a good business. What happens to the things afterwards is another business.
I have never heard about anything sent up by Arianespace having landed on Earth afterwards.
Have you?
Of course Mr. Lone Skum of XpaceS send things up in space all the time and ... lands his first stage booster in less than 10 minutes on Earth again. You can watch his stupid videos on the Internet. They are all photoshop, CGI nonsense. I describe the fraud at my web site.
