> Do you walk at 66,000 miles per hour?
No, but the earth doesn't spin that fast, either. It revolves around the sun at that speed, but if it rotated at that speed, we'd go through almost three days in an hour.
> Geosynchronous satellites travel with a fixed point over the earth, they do not outrun it
Their actual speed is faster than the earth's rotational speed, because it's a larger radius.
> the location of the earth in orbit will be in the same place and the rotation of the earth will be such that the sun hasn't moved an inch from the pov of those on terra firma from the time when you left, yet to you a bit of time did pass, and thus, you travelled back in time.
What are you talking about? Because you take off and land from the same spot, you've time travelled? Time will pass the same (again, except for very minute relativistic differences) for you in the spaceship, and whoever's on the ground.
