New paper claims that the EM Drive doesn’t defy Newton’s 3rd law after all
Posted by Andreas Matt in categories: physics, space travel
Physicists have just published new calculations that suggest the controversial EM drive — or electromagnetic drive — could actually work, and doesn’t defy Newton’s third law after all.
In case you’ve missed the hype, here’s a quick catch-up: a lot of space lovers are freaking out about the EM drive because of claims it could get humans to Mars in just 10 weeks, but just as many are sick of hearing about it, because, on paper at least, it doesn’t work within the laws of physics.
Despite that not-insignificant setback, the EM drive shows no signs of quitting, and test after test — including trials by NASA scientists at the Eagleworks lab, and an independent researcher in Germany — has conceded that the propulsion system, somehow, does produce thrust.

NASA wants astronauts to have 3D printed pizza, and this startup is building a printer to make it happen
Posted by Karen Hurst in categories: 3D printing, food, robotics/AI, space travel
This needs to be on the commercial carriers especially for those 4+ hour flights.
An Austin, Texas company, whose founders were commissioned by NASA to develop palatable foods for astronauts’ deep space mission to Mars, has built a device that can 3D-print pizza.
The company –known as BeeHex — boasts that its machine is efficient, clean, and capable of churning out a delicious pizza in less than half the time it takes a typical human chef. The tech is being developed for astronauts, but since NASA’s manned mission to the Red Planet isn’t planned until the 2030s, us Earthbound eaters may be able to enjoy a 3D-printed pizza at theme parks, shopping malls, or concert halls by early 2017.

The first ‘Star Trek’ VR game arrives this fall
Posted by Shailesh Prasad in categories: entertainment, space travel, virtual reality
If you’re a Star Trek fan, the odds are that your dream game (outside of a Holodeck) involves helming a starship as if you were really on the bridge. Well, you’re about to get your wish: Ubisoft has teased Star Trek: Bridge Crew, the sci-fi series’ first-ever virtual reality game. The title is set in JJ Abrams’ Star Trek universe, and has you taking on the captain, engineer, helm or tactical stations of the remarkably Enterprise -like starship Aegis as it resettles what’s left of the Vulcan population. Think of it as a very sophisticated VR version of Spaceteam — you have to coordinate with the rest of your crew to explore the galaxy and fight off enemies.
Bridge Crew arrives this fall and will support both the HTC Vive and Oculus Rift on PCs as well as PlayStation VR. More details will have to wait until Ubisoft’s E3 press event on Monday, but it’s already clear that the publisher is making good on its promise of a big VR gaming push this year. We wouldn’t be surprised if Ubi has more extra-immersive games to show when it takes to the stage.

NASA Funds Aerospace Corporation for Superlight Debris Removing MiniSats
Posted by Klaus Baldauf in category: space travel
[Via Satellite 06–009-2016] NASA has awarded The Aerospace Corporation a grant to investigate the possibility of developing an extremely thin spacecraft that would wrap around debris and remove it from Earth’s orbit. The concept, called Brane Craft, is a 1-square meter spacecraft that is less than half the thickness of a human hair. The Brane Craft would only weigh about 50 grams, significantly less than even a standard CubeSat weight of about 1 kg. The 30-micron-thick spacecraft would have a very high thrust-to-weight ratio, and would be capable of travelling long distances, which opens up other possibilities beyond just the removal of space debris.
“The Brane Craft concept is based on the one-dimensional compression of a complete spacecraft and upper stage into an essentially two-dimensional object in order to maximize power-to-weight and aperture-to-weight ratios,” said Siegfried Janson, Aerospace Corporation’s senior scientist of the microsatellite systems department and the lead investigator on the project.

Venus Floating Station Concept — NASA
Posted by Klaus Baldauf in categories: engineering, habitats, space travel
For a planetarium program intended to show possible future NASA exploration directions, Home Run Pictures was tasked with creating plausible human habitats on the various planets and moons in the Solar System. Engineering concepts required understanding of the environments and the structures or spacecraft necessary for longer term human survival. Avoiding being too science fiction was difficult at times. The surface of Venus is a rough environment with temperatures and pressures at the extreme. But the dense atmosphere seems to allow the possibility of “floating” a space station hanging below some sort of blimp-like structure. An attempt at using what would look like modular structures, similar to what has been used with the International Space Station was implemented. A circular structure was used to keep the station in balance in the turbulent Venusian upper atmosphere with a long strut hanging down from the center to help stabilize the craft and provide mounting points for various experimental packages and docking ports for shuttles or exploratory probes. Small shuttles would drop into the upper atmosphere delivering cargo and personnel. When the station’s scientists desire to dive deeper into the Venus atmosphere for exploration, shuttles that lean more towards the submersibles used for Earth ocean exploration are used. The Venusian atmosphere is very dense and the pressure would crush anything but craft that are constructed like submarines with reinforced portholes instead of windows. Instead of using rocket power for maneuvering, the shuttle/submersible vehicles use large turbo-fan like engines. Everything needs to be constructed of cororsive-resistent materials to survive the acidic Venusian atmosphere. Scientists theorize that massive lighting events would be the norm and electronic and digital hardware would need to be insulated from the extreme electrical environment.
