Yes, that's correct.
Alan Sheppard is safe though. The time frames involved are strictl limited. Not so w/ cosmology or evolution.
No, the "time frames" with regard to the laws used to predict planetary motions are NOT limited, strictly or otherwise. The are, in principle, arbitrary and unlimited, both as to prediction and retrodiction.
I mean, yeah, obviously the Apollo mission needed to know about the position of the Moon at particular times, but the principles they employed could have told them the position at any arbitrary time, past or future. That's the nature of the relevant equations. They don't "care" what date you solve for, or how distant it may be.
You can't say the principles are "metaphysical" or not "metaphysical" solely because of the particular date the equations happen to be solved for in one certain instance!!! Especially when you've offered no guidance whatsoever in determining which dates fall into a "strictly limited" time frame and which don't!
