NASA InSight tapped for Mars drilling mission in 2016

The surface of Mars? Psh... been there. With the Curiosity stage well under way, our exploration of the Red Planet is about to take a dive beneath the dust. Interior Exploration using Seismic Investigations, Geodesy and Heat Transport -- InSight, for short -- was just confirmed as a new NASA mission, with the space agency set to launch in March of 2016. Based on the Phoenix lander, the craft is tasked with giving us a peek beneath the planet's surface, armed with tools that include a geodetic instrument from the Jet Propulsion Laboratory, which will be used to calculate Mars' rotation axis, a seismic wave sensor and a subsurface heat probe, to measure the planet's internal temperature. The program has a $425 million budget -- a bit shy of the $2.5 billion allocated for Curiosity -- not including the costly launch vehicle. NASA Administrator Charles Bolden said that InSight will help pave the way for future human missions to Mars, and represents just one of the related projects to come. Hit up the source link below for a closer look at JPL's latest endeavor.

MIT ‘microthrusters’ are the size of a penny, could reposition tiny satellites

MIT 'microthrusters' are the size of a penny, could reposition tiny satellites

Bus-sized satellites require massive engines for even the slightest movements, but as far smaller structures become a possibility, a tiny driving mechanism can offer usable thrust. To serve this next-gen tech, MIT saw a need to develop "microthrusters," which are each the size of a penny and can be mounted to tiny cubed satellites. With thruster components measuring a few microns each, the magnetic levitation system is able to accommodate 500 microscopic tips that emit ion beams in a very small package, serving to push two-pound structures through space. The tiny devices have not made their way into orbit yet, but they have been tested in a vacuum chamber. Because of their size, it's possible to add several to each satellite, then enabling sophisticated movements for more precise turns.

There are currently two dozen "CubeSats" in orbit, each measuring only slightly larger than a Rubik's cube, but without any thrusters to power them, positioning can't be adjusted once they're released. Because of their current location, CubeSats eventually burn up in the atmosphere, but once they're released farther from Earth, they won't be able to enter the atmosphere on their own, remaining in orbit as "space junk" even after completing their missions -- micro thrusters could also serve to move these satellites closer to the planet so they can burn up during re-entry. There's no word on when, or even if, MIT's invention will make its way to the launchpad, but you can take a closer look in the demo video after the break.

Project Aether films northern lights at 100,000 feet using a GoPro camera on a balloon (video)

Sadly we can't all be spacemen. Commercial travel beyond the atmosphere is getting closer but still priced way, way, way beyond the budgetary constraints of mere human beings. The closest many of us will get to outer space is photography and, thanks to ever-cheaper and ever-more-durable cameras, getting those pictures is easier than ever. We recently visited Project Aether on location in Fairbanks Alaska, a group working to study what happens in the upper atmosphere and, along the way, inspire students around the world. Using a helium-filled weather balloon and a payload made of carbon fiber tubing, the team lofted a set of GoPro HD Hero 2 cameras, one of which captured photos of the green aurora borealis and, off to the side, the lingering the glow from a long-set sun. That black arc below? That's the earth.

We'll have much, much more to come on Project Aether in an upcoming Distro feature, but for now, enjoy the video below -- and keep your head in the clouds.

IBM: ‘We must build an Exascale computer before 2024’ (video)

ASTRON has enlisted the help of IBM to lead a five-year, $43 million project to develop and build a supercomputer for the new Square Kilometer Array. The SKA is a $2.1 billion initiative to construct the world's largest radio telescope across a 3,000km strip of Australia or South Africa. It's hoped to be around 50 times as powerful as the dishes we currently point heavenward and will be used to examine the deepest reaches of space to learn more about the formation of the universe. When it goes live in 2024, it'll produce an Exabyte of data each day: twice as much information as there is traffic on the internet in the same period. Of course, no existing computer could handle the job, so Big Blue has a slim 12 years in which to turn nascent technologies like Nanophotonics, 3D chip stacking and phase change memory amongst others into a practical, workable Exascale computer. Its either that, or somehow daisy-chain 100 million PCs with enough power and cooling fans to keep it all working and hope for the best. If you'd like to know more, then head on past the break, although unfortunately it won't count as college credit.
