Look into Hubble if you haven't. Just a couple quick notes. The specs of the Hubble telescope, match the specs of the telescope on the plane they call SOFIA. That plane flies in our atmosphere. Some believe that this is what's actually taking the pictures thay claim the Hubble is taking. In fact, they have both released pictures on the same day that match eachother. That makes no sense.

If you study Orbital Degredation, the math says that the Hubble should have plummeted into our oceans years ago, yet they keep "pushing it" back into place. They do not fly missions there to reload the "propulsion" that supposedly keeps it in place. Yet somehow they are able to just push it back into place, without it flying away perpetually, which is exactly why they tell you a voyager type probe keeps flying away perpetually is possible. They push it and it just keeps going because there is nothing to stop it. Yet they fly so close to planets, but never get caught in orbit, but they have no propulsion to get out of orbit.

It's all bullshit.

99%.

Near earth orbit is possible. They can launch satellites into orbit.

They can slingshot it out of the atmosphere.

Once you are in orbit you don't need that much fuel to maintain the orbit. Over long periods of time gravitational irregularities and atmospheric drag do cause low earth orbit satellites to fall out of orbit and burn up but these effects are minimal and only build up over time, so long as you keep things high enough and prevent them from dipping back into the atmosphere they can maintain an orbit for many years on a small amount of fuel.

The voyager probes were able to go past all those planets without falling into an orbit essentially because they were going way to fast. The point of the voyager probes was essentially to fly them out as quickly as possible during a planetary conjunction that allowed for relatively easy access so they could snap pictures. The consequence of sending them out quickly is that they are going too fast to stop afterwards so they just fly past. It was the same with the recent probe to Pluto, in order to get the probe there in a reasonable amount of time, which is still more than a decade, they need to fly it so fast that it's prohibitively expensive to slow it down and insert it into an orbit on the other end.
