This continued for a full orbit, taking over an hour.

Instead, what you really need for orbit is *velocity,* and that's where most of the fuel goes.

Then it would be time to burn for orbit, to return to their ship.

In my mind, I was on a shuttle headed for orbit, away from all of this.

He gave the order, and his ship blasted off for orbit.

The moon took note, as its point pointed straight up for a full orbit.

Once they were gone, burning for orbit, the perimeter closed again.

Compared to the other requirements, communication is easy for orbit and the Moon.

I'm going to try for an orbit around it.

With no one visibly in his path, he headed for orbit and beyond.
