Most of the spacecraft in science fiction are ridiculously spacious, but real life is much less luxurious. The International Space Station (ISS) has just 388 cubic meters of habitable space, and future deep-space assignments could have astronauts serving much longer tours of duty. NASA has partnered with Sierra Nevada Corporation to explore ways to make spacecraft a bit less cramped, and the company has now completed a prototype inflatable habitat module with almost as much living space as the entire ISS.
Humanity's next giant leap could be enabled by next-gen nuclear tech, NASA Administrator Jim Bridenstine said. During the sixth meeting of the National Space Council (NSC) today (Aug. 20), the NASA chief lauded the potential of nuclear thermal propulsion, which would harness the heat thrown off by fission reactions to accelerate propellants such as hydrogen to tremendous speeds.
The number of manmade objects in orbit is set to triple in five years, a reflection of humanity’s growing dependence on ever-cheaper satellites for communication and imagery. Yet more spacecraft means more space debris to threaten them.
