For deep space exploration you need a powerful rocket engine. So NASA developed the RS-25 engine for these future missions on the new rocket, Space Launch System. The SLS will house 4 RS-25s and will be a behemoth of a rocket. See an RS-25 engine can assembled here in an awesome time-lapse video.

When skier Joss Christensen debuted the Trace tracker technology earlier this winter, we were kinda blown away by it. Now we get a look at what kind of data it collects for surfing.

For surfers it actually calculates the angle of your turns and rotations—quite possibly be the first step to ending the continuing argument on surf airs. Besides that, it also tells you how fast you're going and the distance you traveled on a wave. Check out to learn more.

The human race has been getting promised flying cars for decades now, and we're closer than we've ever been. But does that mean we're actually going to be in them in the next couple years? Probably not, but AeroMobil is claiming to be close to a final product on the 3.0 version they've been testing in real flight conditions since October 2014. And they're claiming that it'll be on the consumer market come 2017.

Let's dispel a few things first though about the Aeromobil 3.0: you'll need a separate small aircraft license to operate one, it's projected to cost between $250,000 and $300,000, and just as we've seen with drones, FAA regulators is sort of confused on how these fit into our society moving forward.

We're not really quite sure yet about the merits of flying cars, albeit the prospect of having a vehicle that can drive and fly does seem infinitely badass. Whether or not they're going to be ready for a consumer market and have regulations completely laid out by then is a different story though. Only time can tell when we'll be clogging up the skies next.
