When it came to life on Mars , NASA might have struck out, but it’s got a good feeling about Europa . The agency is working on a probe designed to scan its vast oceans for signs of alien life, but there’s a problem, namely the 30 feet of ice that covers the moon’s surface.That’s where VALKYRIE comes in, a torpedo-shaped robot that’ll suck up water, warm it and fire it back into the ice to quickly and easily drill through the layer. Once the hardware reaches its destination, it’ll release a swarm of smaller ‘bots that’ll map the geography and hunt for alien microbes. There’s still a few issues to work out with the gear, like the fact that it can’t properly change course while tunneling, which would be pretty essential if it were to come across a rock or other blockage. Then again, given that we won’t be ready to launch a mission to Jupiter’s moon until the early 2020’s, NASA’s got some time to fix the problems.

Prototype NASA robot will burrow through sheets of alien ice
First time accepted submitter Carly Page writes When asked for its response to Edward Snowden’s claims that “Dropbox is hostile to privacy”, Dropbox told The INQUIRER that users concerned about privacy should add their own encryption. The firm warned however that if users do, not all of the service’s features will work. Head of Product at Dropbox for Business Ilya Fushman says: “We have data encrypted on our servers. We think of encryption beyond that as a users choice. If you look at our third-party developer ecosystem you’ll find many client-side encryption apps….It’s hard to do things like rich document rendering if they’re client-side encrypted. Search is also difficult, we can’t index the content of files. Finally, we need users to understand that if they use client-side encryption and lose the password, we can’t then help them recover those files.” Read more of this story at Slashdot.
