We’ve already taken baby steps out into the solar system. But cheap, affordable space travel would be revolutionary, heralding in technologies we haven’t even yet imagined.
The International Space Station is ‘filled with germs’.
A security expert discovered a critical flaw in the VxWorks, one of the most reliable real-time operating systems for the IoT also used by the Curiosity Rover.
This is an animated depiction of the novel SHEPHERD spacecraft concept on a mission to gently stop a small asteroid from spinning.
The challenge is to create an antenna and upgraded radio link to enable direct Earth communications but which also must fit on the next upcoming Mars rover mission, Mars2020.
The problem is that as far as we know, faster-than-light travel is impossible, making galactic empires, federations, confederacies and any other cross-galaxy civilizations impossible.
The term breakthrough propulsion refers to concepts like space drives and faster-than-light travel, the kind of breakthroughs that would make interstellar travel practical.
An origami-inspired deployable solar array developed by Brigham Young University may point the way to the future of space exploration and settlement.
The prize, Europa, a watery world. NASA The icy moon Europa is perhaps the most tantalising destination in our solar system. Scientists have been trying for years to kickstart a mission to Jupiter’s most enigmatic moon, with very Earth-like concerns...
