'Tube map' around planets and moons made possible by knot theory

Just as sat-nav did away with the need to argue over the best route home, scientists from the University of Surrey have developed a new method to find the optimal routes for future space missions without the need to waste ...

Space exploration: A luxury or a necessity?

"Oh, come on Daniel, space travel is so expensive, and pointless!" These were the words of my friend Max, during a Christmas party where I was discussing my thesis project: studying places on Earth where the living conditions ...

Image: Pinhole propulsion for satellites

A palm-sized propulsion option for future space missions: Each one of these seven emitter arrays etched onto this silicon wafer using micro- and nano-technology possesses more than 500 pinhole-sized emitters that spray out ...

Research suggests women lose more muscle than men in spaceflight

New research published ahead of print in the Journal of Applied Physiology suggests women lose more muscle than men in a microgravity environment such as spaceflight. The study "represent[s] the longest bed rest study on ...

Communicating with a relativistic spacecraft gets pretty weird

Someday, in the not-too-distant future, humans may send robotic probes to explore nearby star systems. These robot explorers will likely take the form of lightsails and wafercraft (a la Breakthrough Starshot) that will rely ...

Science in space: Robotic helpers

Crew time is a valuable resource on the International Space Station and its value only increases for future space missions. One way to make the most of crew time is using robotic technology either to assist crew members with ...

Metal-poor stars are more life-friendly, suggests study

Stars that contain comparatively large amounts of heavy elements provide less favorable conditions for the emergence of complex life than metal-poor stars, as scientists from the Max Planck Institutes for Solar System Research ...
