You can't just point rockets in earth's orbit at the moon fire them up and expect to get there with only 20,000 miles of thrust! surely the moon wouldn't be in the same place as when you first started meaning you would miss it entirely, I could be wrong but this has bothered me since I was a kid
shareWAIT! You mean this film is NOT a double-fact-checked documentary?! ;-)
Actually, the amount of req'd lbs-force/ N for thrust to reach the moon and determining the point of intersection between both objects is among the least objectionable of inaccurate items in this movie.
There's a LOT of incorrect examples - in the outer space scenes - per the properties of physics e.g., ac-/ de-celeration, inertia, gravity, material strength/ elasticity, & fluid dynamics. Oh, well!
EVERY science-based movie will have such examples.... :-(
P.S. The only person in the family of my best friend from high school onward (who actually designed hand tools in Texas used on the shuttles) whom I've never met: his sister who died aboard the Columbia space shuttle....
It's ALL about perspective & what really matters.
