New this month Continuity mistake: On the way to the ISS, Matt asks Ryan where's home. Ryan replies "What?" and Matt says "Down there. Mother Earth." Behind Matt as he says this is the rope keeping Matt and Ryan tethered together drifting around. At the end of the shot, the part of the rope shown in front of Ryan is shown to be drifting around differently to when it cuts to a shot of Ryan.
New this month Visible crew/equipment: In the Chinese Space Station, Ryan climbs into the Shenzou capsule and seals the airlock behind her. As she seals the airlock, you can see the shadow of the camera to the left of the screen on the wall, moving around. There is nothing there in the station that could have possibly made the shape on the wall.
New this month Factual error: When Ryan enters the space station and removes her spacesuit she is shown wearing only a tank top and boy shorts. In reality, according to NASA's official webpage astronauts wear a liquid cooling and ventilation garment and an absorption garment (space diapers) under their suit.
Factual error: The shuttle's original mission was to service Hubble, yet when the shuttle is wrecked, Kowalsky moves with Stone to the ISS, which just happens to be "a short hike away." Hubble orbits at an altitude of 350 miles/560km, while the ISS does so at an altitude of about 250 miles/410km. Furthermore, even if they had been able to see the ISS from Hubble's orbit, they would have only seen it speed ahead, as their orbital velocities are very different: 7.66km per second for the ISS and 7.5km per second for Hubble.
Factual error: When the Chinese space station is de-orbiting, and the atmosphere is stripping parts off the outside, Dr Ryan Stone is inside with objects floating about her. In reality, there would be a small deceleration caused by the atmospheric drag that would pull all objects to the front of the craft.
Factual error: There are several scenes which depict space debris reaching the astronauts' location, with catastrophic results. While the impact of these collisions are probably realistic, it's highly improbable that this debris would be visible (you can spot many objects approaching, missing or hitting Sandra and George's location) mainly because of their ultra high speed relative to the astronauts' area. Remember, we are talking about orbits with speeds in the order of several 10k's of km/h.
Continuity mistake: When Ryan mentions her daughter, and Matt turns off his music, he hold up his right arm and looks in the mirror, but the shot of the mirror itself is on his left hand.
Factual error: When Stone makes her transfer from the Soyuz emergency escape system to the Chinese Station, she takes 3+ minutes from fastening her helmet to being inside the station. Her space suit does not include an oxygen supply. Only residual air (from the Soyuz spacecraft) is available to her, and a lot of action occurs. She couldn't do it. Too long a time, too little air. The Sokol spacesuit portrayed is intended for intra vehicular operation and requires external sources of oxygen and ventilation to be functional (as depicted in scenes before).
New this month Other mistake: When the fire in the ISS starts, Ryan picks up a fire extinguisher and tries to put out the fire. The effect of the fire extinguisher pushes her backwards and she ends up hitting the back of her head on the wall, yet a cut appears on the side of her face, despite not getting hit in the face. This cut had nothing to do with the fire.
Continuity mistake: After the rope keeping Ryan and Matt tethered together is snapped, Ryan continues drifting downwards towards the Earth. The shot continues panning until the camera stops with the camera high up. As she falls, the ropes from the parachute around the satellite are visibly on Ryan's right. In the next shot from low down, the ropes from the parachute have moved to Ryan's left.
Factual error: Space debris from an exploded satellite orbiting the earth catches up with Ryan every 90 minutes (as she goes from the Explorer to the ISS to the Chinese space station, all roughly at the same altitude). This is physically impossible. To do this, the debris would have to be traveling fast enough to catch up with the orbiting space stations every 90 minutes. However, objects orbiting at different speeds must travel at different altitudes. The faster the orbit, the lower the altitude. So it would be impossible for the debris to "catch up" with the space stations three times. Even if the two were moving in opposite directions, they would collide once every 45 minutes, as the ISS' orbit period is 90 minutes.
New this month Continuity mistake: Just after Matt retrieves Ryan, Matt tells her to set her watch timer for 90 minutes, which she then does. A shot is then shown of Ryan's arm adjusting the watch timer to 90 minutes and the time on the watch reads 00:32. Later on, when Ryan is in the Soyuz capsule, she looks at her watch and says "Seven minutes to get out of here." It is shown that the time on her watch reads 02:21 (1h 49m later) but the timer reads 7 minutes and 26 minutes left of the 90 minutes.
New this month Audio problem: Ryan is on the International Space Station and looking through the window in an attempt to communicate with Matt. During this transmission, Ryan says "Please talk to me. Please." When she says "Please" the second time, her lips don't move. Her lips are perfectly visible through the reflection of the window.
New this month Continuity mistake: When Ryan and Matt reach the ISS, as Ryan says "Wait, you have to brake!" the ISS is visible from the POV of Ryan. About two shots later, another shot of the ISS is shown from Ryan's POV, only now they are way further away from the ISS than they were two shots previously.
Factual error: When Stone makes it to the Chinese station, it is experiencing reentry. This is nothing but a drama-making mistake, as the station would have needed to have been actively boosted down/slowed down for it to have been a deliberate deorbit, or have had its navigation completely neglected for months or years for its orbit to decay to that point. In either of these two cases, it could not have been orbiting at a fixed position with the otherwise-stable ISS.
