OK, so here is my issue.. there are other so called factors, observations and evidences that some hold to be written in stone... as proof of a globe.. yet, like this one.. you say it is not something that affects snipers... While others would bet the farm, argue for days ad nausium... that it is.
Not in the talk that I heard, given by an expert... there were many variables... spin of the earth was not one of them.
Kinds puts the lie to this claim ...
These women are not identical to the Challenger crew members. In both cases, the womens' faces are too long, and their features much more spaced from top to bottom.That's right, 6 out of 7 found same full name or surname, right age group, look identical (2 identical twins!) Sure, sure. You're a coincidence theorist, tell me what are the chances of that?
Judith Reznik - Judith Reznik
Sharon ("Christa") McAuliffe - Sharon McAuliffe
Now what are the chances, what are they mate? Come on champ, come on tiger, crunch the numbers, do tell.
Your question answers itself.
The moon, as an object of mass, always exerts a gravitational effect ... that corresponds to its mass ... and the distance between it ... and other bodies of mass.

The moon, as an object of mass, always exerts a gravitational effect ... that corresponds to its mass ... and the distance between it ... and other bodies of mass.
The moon is kept in orbit by the centripetal acceleration force (i.e. centrifugal force) caused by it's orbital speed around the earth.
Just like when your car goes around a curve, ... and you experience a pulling force away from the center of the curve's arc.
Physics for Animators
Certainly high-quality, long-life seals are required, but that vacuum pressure isn't 'stronger' than anything down here, it just means the pressure is very nearly zero. Space doesn't suck with increasing negative pressure, it has a pressure close to zero. Spacesuit and space-station seals only need to resist atmospheric pressure (760 Torr, or 1.013×10^5 Pa).
De-gaussing means demagnetising - did you mean 'degassing'? You vent excess pressure by opening the valve until the pressure reduces to the required level. The fact that there's no back-pressure in space means you can do this without having to pump out the excess fluid. Any filters that are likely to need changing are placed inside the pressurised hull.
Space systems are designed to be low-maintenance with ease of maintenance, e.g. plug-n-play swappable, with pre-planned maintenance & replacement schedules. Some spares are kept on board but can be sent up with supply missions. But things do go wrong, and astronauts may need to make spacewalks to do repairs - for example, when the ISS cooling system ammonia pump failed in 2010, the astronauts had to make over 25 hours of spacewalks to replace it. See ISS Ammonia Pump Failure.
