MOSS:

    Virtual assistant is a person who provides support services from a remote location. In the case of Siri, though it is not a real person, it still uses voice queries and a natural language user interface to answer questions, make recommendations, perform actions, as well as delegate requests to internet services. 
    Though this technology has not been fully tested to be used in space station, it has been working well on Earth. It is realistic to expect its further development and underlying applications in space stations.

​

Hibernation Units:

    Cryonics can provide low-temperature freezing and storage of humans, with a speculative hope of possible resurrection in the future. 
    Currently, this technique is not admitted by mainstream scientists

​

Space Station:

    The International Space Station (ISS) is built from 1998 to 2011. The ISS contains 230 astronauts by 2018 who come from 15 different nations. However, unlike the space station in the movie, China is not part of the member in the ISS. 
    China is also working on building its own station, according to a more recent news. The space station is planned to finish construction in 2022. A previous experimental space station Tiangong-1 was built in 2011, but unfortunately crashed in 2018.

​

Communication Terminal:

    The movie portraits the terminal with a huge circuit dedicated to control the engine, similar to how ENIAC is. Operators need to hard wire the system in order to get hack the terminal. Comparing to modern day devices, the size of the terminal is massive.
    Based on the amount of dust on the terminal, it is very likely that the engine never required maintenance in any form, unlike the ENIAC, which can malfunction on a daily basis due to a broken vacuum tube. 

​

Wearable Terminals:

     In the movie, those who go outside wear suits equipped with a device on their wrist which allows them to view their own health, the health of teammates, and communicate within the broadcasting network. A combination of current technologies we have today could lead to this device. For example, there are currently Fitbits and Apple watches which are able to track heart rate and perform ECG readings and these are wearable devices. They also include GPS location transmission and allow for texting and calling. By making improvements to the strength and range of these devices, it is possible for them to become similar to that of the movie in 40 years.

​

Emulated Skies:

     Since majority of the population in the movie lives within underground cities there are emulated skies which provide the experience of real skies for people. In today's society we have a similar device to this on a much smaller scale. There are movie theaters and science museums which have domed movie screen ceilings. These screens are often used to play videos of outer space and the solar system. They provide a sort of virtual reality experience and immerse viewers into the experience. If these devices were made much larger scale, it would essentially be exactly what is used in the movie.

Earth Engine:

     The Earth engines in the film are in essence are huge glorified rocket engines. The technology in the real world is definitely present, but it is the extent of which that is questionable. For example, the earth has an estimated mass of 6*10^24 kg. To accelerate the earth up to one G (9.8 m/s/s) it would take 6*10^24 Newtons. That doesn't even take into account stopping the earth's rotation. Nasa's strongest ever rocket engine, the F1 engine, has a maximum thrust force of 6.7 Mega Newtons, or 6.7*10^6N. It would take at the very least, with these rudimentary numbers and ideal conditions, 8.95*10^17 F1 engines to even move the earth. At the moment with our current technology, it would be very difficult to execute this. However, in the future and under circumstances such as in the film, it would not be impossible.

Transporter:

     Besides the space station (which has an already existing equivalent in the ISS) the transporter is by far the most realistic device shown in the movie. It is essentially a military grade truck that can survive the harsh temperatures present in the sunless surface of earth. The only foreign aspect of the vehicle is the unique spherical mannerism used instead of a steering wheel to drive the transporter. Besides that, there are multiple US Army vehicles (Land and Air) that have the same physical capabilities, such as the American JLTV which has multi-hundred pound doors of armor, and the American Stryker that weighs 19 tons that can withstand explosives and has sensors alerting crew of potential bio hazardous contamination.
