Why is Ryan, a medical doctor, performing maintenance on the Hubble telescope?
How come Matt doesn't seem to know a thing about Ryan, despite having trained with her for six months? I'm sure that they'd had plenty of time for small talk, and all Matt seems to know is what Ryan does for a living.
There is no possible way that you could see the ISS from the Hubble telescope; They are on radically different orbits from each other. Furthermore, intercepting the ISS from Hubble would be downright impossible for one guy with an RCS jetpack.
The satellite debris always seems to come from a different angle every time it hits something, and although Matt says it makes a full orbit every 90 minutes, (which is fairly accurate) it hits other things in other orbits at exactly the same time. Is it homing debris? did Matt and Ryan insult the debris' mother and now it's out for blood?
When Matt and Ryan hit the ISS and Ryan gets caught in the chute cable, they both should stop moving. Instead, Matt keeps getting pulled away by some unknown force. Centrifugal force is out, because nothing is spinning.
Ryan should be wearing a lot more under her suit than a tanktop and boyshorts. She also should have noticed the immense fire hazard she floats by on her way to the escape pod.
There are supposed to be controls inside the escape pod to detach the parachute. We never see her try to use these controls, so either she was unaware they were there, or they weren't there altogether, which would be an enormous safety hazard.
Also, I'm pretty sure there was an agreement between the Russians and the US that everything had to be labelled both in Russian and English, however, all the buttons in the pod are in Russian, supposedly with an English manual.
When Ryan cries, the tears should not be flying away from her face. In zero-g, the surface tension of the tears would cause them to pool up on her face,
as demonstrated by Chris Hadfield in this video.
Why does this Chinese man with a dog and a baby keep staying on the (phone? radio?) with Ryan when he doesn't understand a word she says?
I know it was all a hallucination, when Matt opens the airlock while Ryan doesn't have her suit on all the way, the explosive decompression would have sucked all the air from her lungs and vaporized most of the moisture in her body. I'm sure even her CO2-addled brain would have taken that into account.
Apparently we are expected to believe that someone who, in six months of training, failed the escape pod simulation every single time, was cleared for a mission.
Do the people at mission control always play country music over the radio, or is it just for special occasions? Speaking of which, did Matt sneak an MP3 player into his suit, or is the ability to play music during EVA an important feature that they just had to include in his experimental RCS pack?
While Ryan is in the Chinese escape pod on its way out of the atmosphere, the heat shield flies off, and before that, the shield wasn't even pointed in the right direction. The shield was in effect for only a few seconds, and yet all that happens to the pod is it gets kind of hot and some of the electrical systems short out. By all rights she should be a charred husk in a ball of slag. Also, it was pretty lucky she came down in such shallow water so close to land or she would have drowned when she opened the hatch and let the craft sink to the bottom.
