Space experts swoon over 'The Martian' despite inaccuracies

Haven't seen the movie. I was a rocket scientist for NASA-JSC for 7 yrs. So far, the most realistic movies that I've seen are:

Europa_Report - space scenes only - the launch parts from Europa are highly unrealistic. The stuff "in space" is pretty accurate.

All the others are so wrong with the science as to be fantasy. I couldn't stop laughing at Interstellar. So much of the practical physics was wrong - oh - so wrong. Fuel and oxidizer tanks aren't sexy on film. There isn't anything like artificial gravity in the real world without spinning or constant acceleration and none of our spacecraft have that capability today. On a Mars mission, it would be very important to have gravity for most of the trip. Constant accel isn't practical - can't carry that much mass to throw out the back. Spinning is the only practical method for the rest of my lifetime.

If they can't get the gravity correct - forgetaboutit. Mars gravity is 62% lower than Earths. 100Kg here is 38Kg on Mars. The math for how high you can jump is easy stuff. Nobody would walk like we do on Earth when gravity is that different. It would be more like how the moon landing people hopped around (though Moon gravity is about 50% less than Mars gravity). With lighter spacesuits, the stride would be longer if muscle was maintained to Earth strength.

I look forward to NOT having to check my mind at the door of the theatre, but that isn't likely.

The book was quite entertaining and it seems the film is quite similar.

Now that they've found water on Mars kind of makes it out of date now I suspect.

"Not to mention that NASA is still working on the machinery to rocket humans to Mars. "

I have a dream that all the wars will cease and mankind will send humans to Mars and bring them back.
