Want to build stuff for Space; well you may need to move from earth to a spacelab. I can see the job ads “want to see and experience other planetary worlds; live for adventure, see space; sleep near Mars, etc.”
Any robust future in space will almost certainly require a way to build there — and that future might not be as far out as you think!
The idea of a space elevator to lift us into orbit is one of the oldest concepts in sci-fi, but thanks to the efforts of scientists in Japan, we might soon be seeing this fantastic feat of engineering become a reality at last.
A mini satellite called STARS-C (Space Tethered Autonomous Robotic Satellite-Cube) is heading to the International Space Station in the coming months and is a prototype design that could form the basis of a future space elevator.
Once STARS-C has been delivered – on some to-be-determined date after the Northern Hemisphere’s summer – its makers at Shizuoka University will put it to the test: the orbiter will split into two 10-cm (3.94-inch) cubes and spool out a thin 100-metre tether made of Kevlar between them.
X literally marks the spot in the center of the Milky Way, a phenomenon that offers clues about the galaxy’s formation.
“Computational design tool transforms flat materials into 3D shapes” — I could use this many times over.
Researchers at Carnegie Mellon University and the Swiss Federal Institute of Technology in Lausanne, Switzerland (EPFL) have developed a new computational design tool can turn a flat sheet of plastic or metal into complex 3D shapes. They say the tool enables designers to fully and creatively exploit an unusual quality of certain materials — the ability to expand uniformly in two dimensions.
In this case, the researchers were making hexagonal cuts into flexible, but not normally stretchable plastic and metal sheets to give them the ability to expand uniformly, up to a point. But the design tool could be useful for a variety of synthetic materials, known as auxetic materials that share this same distinctive quality.
Origami-style folding techniques have already helped produce devices such as cardiac stents, which must be maneuvered into the narrowed artery of a heart patient and then expanded to hold the artery open, and solar arrays that unfold after being launched into space. Auxetic materials could be used in similar ways, while also exploiting their additional capabilities.
“Virgin Spaceship Unity, set to begin test flights next month, includes a very special nod to the theoretical physicist.”
“The UK Space Agency is investing £4.12m in a National Propulsion Test Facility, giving the UK a new facility for space technology testing.”
“Kenyan policy makers and experts are rooting for the use of space technology to enhance wildlife and ecosystems management in the country.”
According to our best theories of physics, the universe is a fixed block where time only appears to pass. Yet if the flow of time is an illusion, how do we account for the distinction between past, present and future? In June, 60 physicists gathered for four days at the Perimeter Institute for Theoretical Physics to debate this another questions about the mysteries of time.
