Looking forward to the first manned Mars mission, ESA is delving into how astronaut hibernation would affect space missions. Based on sending six humans on a five-year mission to the Red Planet, the study suggests that using hibernation would allow the mass of the spacecraft to be reduced by a third, and the amount of consumables cut by roughly the same amount.

The idea of astronauts sleeping their way through a deep-space mission lasting months or years has been a staple plot device of science fiction since at least the 1930s and has featured in many movies as a way to speed up the story. Despite the chance of waking up to find one’s self on a planet run by apes, it’s an idea that is very attractive to real-life mission planners as a way to both reduce the supplies needed for lengthy missions and to keep the crew from going crazy.

The technology to actually make humans hibernate like bears or other mammals is still in its infancy, but that hasn’t stopped ESA from looking at how hibernation could impact spacecraft designs and missions in general. Originally, studied as part of the space agency’s Basic Activities research, hibernation is regarded as a key enabling technology and now ESA’s Concurrent Design Facility (CDF), along with scientists from the Ludwig Maximilian University of Munich and the University of Goethe, Frankfurt, are looking at the advantages that sleeping astronauts might bring to a Mars mission.

“We want a new space race—space races are exciting,” declared SpaceX founder Elon Musk after the successful inaugural flight last year of the Falcon Heavy, the most powerful rocket since the Space Shuttle.

Hawks and headline writers think space races are exciting too, especially the “new space race” between China and the United States. That’s why they keep referring to it—even though it doesn’t exist.

Historic changes are indeed afoot in the space sector. Private crewed spaceflight is about to come of age. Mobile robotic spacecraft are being built to rendezvous with satellites to service them. Vast swarms of broadband satellites are set to make the Internet truly global for the first time, and increase the number of spacecraft in orbit tenfold. Back on Earth, satellite imagery fed through artificial intelligence algorithms promises powerful insights into all manner of human activity. Dozens of countries are active in space and the number is growing all the time. The tired trope of the superpower space race does little to make sense of all this.

The innovative technology used to settle on the Red Planet will prove to be very useful on our own homeworld.

This new space plane just got one step closer to liftoff, and it could change spaceflight to the ISS in years to come.

Researchers launched a drone from a pneumatic baseball pitching machine strapped to a truck traveling 50 miles per hour. They hope this ballistic launch method might lead to drones that are better suited for emergency response and space exploration missions.

Launcher says one-piece manufacture lowers the cost of its part, compared with those printed in pieces and joined. To do this, the Brooklyn-based startup teamed with 3D printer companies to build a space large enough for its entire copper-alloy part, which itself is a huge investment.

Process is initially intended to save lives on Earth, rather than to send astronauts on long haul flights.

In movies and books, fictional astronauts enter ‘suspended animation’ to cross the vastness of space. Recently ESA investigated how real-life crew hibernation would impact a space mission to Mars.
