Oh you flat earth people never give up. NASA doesn’t say nothing can go above low Earth orbit. We just launched a satellite that is now way above low Earth orbit.
To orbit Earth there has to be very little atmospheric drag. Even at 250 miles, way higher than Mount Everest where the air is already very thin, there is still, although slight, some drag by the sparsely populated air molecules at that altitude. That’s where the ISS is orbiting. Every once in awhile the ISS needs a boost to stay up there because it tends, over a long period of time, to slow down due to the atmospheric drag. That’s why it’s called low Earth orbit.
We do, however, have many, many objects that are much higher than low Earth orbit. This includes the new GOES satellite that was just launched the other day and placed in geostationary orbit 22,236 miles above Earth. That’s where your Dish Network, DirectTV and Sirius/XM Radio satellites are as well. Here is a photo taken of Earth from that altitude, where you can clearly see the earth is spherical.
