There is next a cut to him flushing the toilet in which he seems to have the idea to go back to a cabinet and so he discovers the potatoes.

Moreover, the receptacle for inserting a coffee pod is also at the top of the unit which would be hard if not impossible to get to anyway. During text messaging with NASA messages appear letter by letter at the receiving end, just like as if they were being typed. Soundtracks. As shown, the spacecraft is burning prograde instead of retrograde.

Early in the film Watney takes an inventory of his food supply.

Such a joint would be very complex, expensive and a high risk of failure. They should be simple slabs with rounded tops.

If the Hermes crew could create an explosive to be used as a bomb, it would be far safer & more-effective to use it as propellant fuel to slow the ship, rather than to intentionally damage the hull. It would probably be sufficient to push Mark towards the ship, slowly, and he wouldn't want to close the distance all that fast anyway. When NASA Mission control is watching the supply rocket explode upon ascent, it shows a reaction shot of Mitch Henderson, with Vincent Kapoor being seen behind him. The stuff is bundled up in a tarp and strapped to the roof of the rover over the hole. A botanist should know that. When Mark reaches Ares IV, he exits the rover and while the door is clearly open the tarp he installs in the roof remains inflated, when it actually would have depressurized immediately. The individual NASA facilities have directors. First, the moment he breaks the seal, his arm might have flopped around, even causing his body to spin wildly.

However, while in deep space, a brief shot shows Vogel walking in the background. The film shows Watney following a parachute and shrouds to find the buried Pathfinder lander, but the Pathfinder used a unique airbag system that involved cutting the lander loose from the parachute and Rocket Assisted Deceleration System above the surface.

The "Chinese space center" is actually the Palace of Arts (Muvészetek Palotája) in Budapest, Hungary. They never show him shorting out the Pathfinder lander and losing communication with Earth in the movie, so it should have therefore been possible for him to get permission.

As the NASA psychiatrist is about to interview Watney, he has his hand to his face, holding a pen. Not to mention that the camera angle doesn't match the video feed. The difference in voltage would have instantly fried the probe. https://the-martian.fandom.com/wiki/Rover_2?oldid=5095. If Pathfinder's camera did not move after a reasonable period of time, Mark would know that Earth never received his transmission and that he would have to redouble his efforts to contact NASA. In the video recording shot, however, Mark's hand is at his chest and there are maps on the table. Beth tells him that it is a text file and opens it. When Mindy Park receives the Email from Vincent Kapoor (at 1:30 AM) she's asked to check the coordinates at 46.7°N 22°W and zooms right into the Hab, but later in the Cafeteria, when plotting Marks course on the framed picture, when asked the Hab location she points at the image and states 31.2°N 28.5°W.

At various points in the movie, the "head up display" of Watneys space suit is shown, giving environmental and suit data on the atmospheric pressure and oxygen content.

This is the same physical principle which causes an ice skater drawing her arms against her body to spin faster. Adding liquid oxygen (-183 C/-297 F) to room temperature sugar crystals (20 C/68 F) would most likely pre-detonate from any jostling. Pathfinder requires direct line of sight in order to broadcast its signal to Earth. RTG's must radiate waste heat through their cooling fins in order to generate electricity, burying one underground would have prevented it from functioning. Air escaping a hole in a glove would push with about the same force as a person generates blowing out a candle.

After deciding to go and rescue Mark Watney, the Hermes crew is evaluating their resources. It would also be much more likely to happen within the airlock, in the area between the two doors, where the strain on the walls (which look flexible, but are never shown to flex as the pressure changes) changes with each pressurization or depressurization, than on the Hab side of the inner door where the pressures would be constant, but there's an outside chance that it could have been coincidence, bad luck, and/or the airlock jiggling as it cycled. | It would not be possible, however, for his entire body to be launched, even if the escaping gas actually created the necessary force. An ascent vehicle (meant to rendezvous in space with Hermes) wouldn't need heat shielding DURING the ascent, but it would during its descent from space to the Martian surface, and it might need it again after a failed ascent with a crew still on-board.

Orbits and gravity assist maneuvers don't take much computing power to calculate, are commonly used for all sorts of interplanetary missions, and are well understood by most people working at NASA. Also, according to data from the Curiosity rover, Martian soil contains roughly 30 liters of water per cubic meter. Rover 2 was the rover that Mark Watney used. If it could have been opened or closed remotely then Beck wouldn't have had to place the bomb and traverse the exterior of the ship.

Why suddenly liquid protein cubes would cause an imbalance is also a mystery unless they were bulk packed and able to coalesce into a large fluid mass moving substantially within the rocket. Many of the scenes aboard the Hermes show astronauts maneuvering around the passageways with somewhat unrealistic changes in direction. The film seemed to imply that NASA communicates with deep space probes by working with identical spacecraft on Earth, as seen in all of the Pathfinder scenes. He should let the engines burn all their fuel. With the airlocks of the entry shaft/storage compartment, containing the space suit(s), still intact, he can safely take off his Mars surface suit, shave and put on his space suit - otherwise his unprotected exposure to the Martian Atmosphere would have killed him pretty quickly. If the rover is cold without heating this should be equally if not more unbearable. Much of this water can be extracted by simply heating the soil. The flexible cover would have been inflated like a balloon on Earth holding in 7psi over atmospheric, and no wind in the near vacuum of Mars would cause it to billow in and out.
