several science mistakes in this movie

Rating: 4/10 (12 August 2017)

Probably The Most Weird bit of all is the fact that Matt says that an explosion from a sort of water generator was caused by the excess OXYGEN that he breathed out: 1. You breath out co2 not oxygen 2. you would not cause an explosion by breathing a single breath of wind 3. How would like 10gs of wood chips burn for some like: 200 sols? he would need 10 kg instead of grams.
Duct tape does not help in taping together a hole. It just doesn't. And I don't see any seals in that. all there is is a tarp and a few straps and duct tapes strips to seal it together. Mark uses duct tape to fix his spacesuit, attach a dangerous plutonium reactor, and to seal of a giant hole in the wall of the HAB, the base of the mission. The alarming fact is that it is 100% worrying when you hear the flapping sound of the tarp, and sending a person on a rocket ship with its nose cut off and replaced with a tarp is totally nonsensical.
Overall, This is an okay movie but if you are one of those experts on film better not watch it. or if you are a scientist.
