That's the most likely answer.

The Enterprise in it's "dry dock" was above the city of San Fransisco, you could make out geographic features on the ground. The Enterprise's starboard side was facing the ground and the dorsal direction was north.

At theis point the ship is in fact orbiting backwards.

Given the apparent size of the Earth, the ship, dry dock and space station are not in geo orbit.

When the ship left dry dock it actually did so by slowing it orbital speed, but was still moving ass end first. The dry dock now fpreceeding it in orbit.

The sun rising as it does is completely acurate.


Whether the enterprise is moving ass end first in relation to the earth as it departs space dock depends on whether the dock and the ship is in a prograde or retrograde orbit. If the dock was in a prograde orbit, then the scene is plausible as the camera and the ship is racing eastwards and outrunning the earth's day-night terminator line, and is in effect hurrying into the sun rise, the only point being the ship is racing backwards towards the terminator slightly slower than the camera and so appears to be moving slowly forwards towards the camera.
If everything had been in a retrograde orbit,ie moving west, then enterprise is indeed racing front end first. In this case the scene is impossible as enterprise must be below geosynchronous orbit and running west at a higher speed than the day night terminator.

Does it make that "beep-beep-beep" sound?

^No, they didn't have time to run by Talos IV and pick up Pike.

In space, no one can hear you beep...

It's in neither, the Enterprise, the drydock and the station (I'm calling "the group") are geostationary above the city of San Francisco. Nor is the group in a geosynchronous orbit, from geosynchronous orbit the Earth is only 17.3 degrees wide, that like a 22 inch circle seen from 6 feet away. Checkout the pictures in the OP, the Enterprise (and earlier the group) are only a few hundred miles up.

A geostationary position is by definition prograde. It is revolving around the earth in the same direction as well as angular rate as earth's rotation.

I also think it is unlike the group is geostationary without being geosynchronous. If it were, everything in the group have to constantly apply power and expand energy to fight earth's gravity to keep station. In this case, A star ship without functioning engines like the enterprise undergoing refit would have to be physically held up, and wouldn't just float effortlessly in the middle of its refit dock. The guys in EVA suits summersaulting around the enterprise in the dock would also not just float, but need their own anti grave and power source to hold them up.

That's not the Earth's sun, it's the one that shines out of Kirk's arse.

[QUOTE=Chuck4;8727136... it is unlike the group is geostationary without being geosynchronous. If it were, everything in the group have to constantly apply power and expand energy to fight earth's gravity to keep station.[/quote]Thisd is what I believe is happening, not just in this instants, but also when the Enterprise is over a fixed spot on a planet.

This is part of what the 'drydock" does, think about it, doesn't the drydock seem overly massive if all it's doing is holding arrays of lights?

Part of what it is doing is holding the ship at that altitude, an artificial gravity bubble. I think it also provides shields to protect the people working on the ship from solar radiation if needed.
