Richard Lewis, the film's producer and co-writer of the story, wanted to explore the idea of pregnancy and childbirth in space travel. No pregnant astronauts have ever been in space, and that's the main reason this story came about. But one facet of this field of research for which there currently is no available evidence is pregnancy. Scientists are constantly learning more and more about how the human body performs in microgravity, thanks to the research done by astronauts aboard the International Space Station.

"The Space Between Us" features a realistic representation of the Mars Transfer Vehicle, a spacecraft concept that may one day carry astronauts to and from Mars.

The spacecraft has only done orbital test flights so far, but it's scheduled to make its first uncrewed flight to the space station in 2019. Dream Chaser is designed to carry cargo to the space station and can carry up to seven astronauts. The filmmakers also got access to a real spacecraft that has already been built (but never flown): a prototype of the Dream Chaser, which looks like a mini version of NASA's space shuttle. The MTV is just a concept for now, but it may be how future astronauts travel back and forth between Earth and Mars. There, the astronauts ride a descent vehicle down to Mars while the MTV hangs out in Mars' orbit. After the crew docks, the MTV provides the astronauts with a more comfortable enclosure for the seven-month trip to Mars. This huge orbiting spacecraft is actually a Mars Transfer Vehicle (MTV), which is based on Lockheed Martin's " Base Camp" design. In "The Space Between Us," after the astronauts launch atop the SLS rocket, their crew capsule meets up with a spacecraft that looks a lot like the International Space Station. Ultimately, NASA hopes to use the rocket for missions to Mars and beyond. Its first launch will send an uncrewed Orion capsule on a trip around the moon before launching astronauts on a mission to an asteroid. The rocket, designed to carry humans beyond Earth's orbit, is currently in the development stage and slated for launch in 2018. One of the movie's spacecraft that could fly in the next couple of years is NASA's Space Launch System (SLS).
