To maintain "a speed of approximately 403,000 kph on the Moon" the largest energy vector would be pointed toward the center of mass.

Now the oomph provided by our natural satellite's rotation is greatest at its equator. Since the equatorial radius of the Moon is 1738.1 km, the uncorrected escape velocity is 2375.42 m/sec. Subtracting .7363 yields a corrected value of [math]2374.68[/math] meters/second…assuming an optimal launch direction. |
Escape velocity is 1/5th of Earth's. ....Theoretically.
