Gravity Fact Check: What the Season's Big Movie Gets Wrong, Jeff Kluger, Time
"... the physics of moving about in space--thrusts requiring counterthrusts, spins requiring counterspins, the hideous reality that if you do go spiraling off into the void your rotation never, never stops--are all simulated beautifully, scarily and accurately."
NASA expert explains what the Gravity trailer gets wrong, Michael A. Interbartolo III, Blastr
"I am all for an entertaining movie, but when I go into a Michael Bay Armageddon movie I know to turn the brain off. This one tries to pass itself off as something more than that, but to me, it is the same flash and sizzle with a pretty lax understanding of orbital mechanics and spaceflight operations."
Keith's note: Michael Interbartolo actually does this space stuff for a living.
