I think the coolest part of the article is how it mentions that new rockets would take the trip from eight or nine years and make it a measly two years. To reach Jupiter.

Yeah, I'm doubting that this report is actually from NK.

More SpaceX news: http://www.extremetech.com/extreme/178389-spacex-prepares-to-take-the-biggest-step-towards-affordable-space-travel-soft-landing-the-falcon-9-rocket
SpaceX next launch is this Sunday early in the morning, and will be webcast live. More importantly though, they will be attempted to soft-land their rocket, similar to what they did with their Grasshopper prototype. Since it is still very much an experiment, they will be soft-landing in the ocean, but still. So Sunday morning if you get up early/stay up late, you could see a soft landing of a Falcon 9 first stage. As per the article, if that goes well, future missions will see attempts to soft-land both the first and second stages back on the pad.

tldr version: see an autonomous sub-orbital  VTOL lander on sunday

Edit: Scratch that, time was delayed a couple weeks. Now set to launch on the 30th or something like that.

Bump for more SpaceX news:
Today the aforementioned launch took place; the first stage apparently made a successful landing over the ocean, as evidenced both by the final telemetry they received and the final transmissions to the tracking aircraft indicating transmissions for 8 seconds after touchdown in the ocean until it rolled on its side (or in other words, it landed fully intact rather than smashing into the surface and disintegrating). Unfortunately no video of the touchdown, due to rough weather and clouds preventing the recovery ship from being in a good observation position.
Video of the launch: https://www.youtube.com/watch?v=iLJ3vns3Zys

Additionally, a test took place yesterday of their new Grasshopper replacement. This new rocket is around twice the height, and is really just a Falcon 9 first stage, pretty much the same as what landed today. Video here, with the grasshopper rocket nearby (on the right at the video start): https://www.youtube.com/watch?v=0UjWqQPWmsY&feature=youtu.be

This is all quite impressive for a couple reasons. First and most obvious, it means they've basically got a working reusable first stage for their rockets now, which is pretty big in itself. A second impressive feat is the fact that they launched both the vehicle in the video followed up by a launch to the ISS with a separate vehicle in about a 24 hour timeframe. One of them may not have been a full to-orbit mission, but such a small turnaround time on launching a test flight to launching a mission coupled with a test landing is pretty darn cool.

On a side note, spacex apparently has really good wiki pages with even more details than you would get in a KSP part config.

Well, anyway. Bit late, but the ESA launched it's Sentinel sattelite two weeks ago.

And nobody said anything about Kepler-186f?
It's 500 light years away, 1.1 times the size of earth, orbit a dim red star, and is totally within its star's habitable zone.

I was under the impression that a planet in the habitable zone of a red dwarf would also be in the radius to likely be tidally locked.

Well, SpaceX published some video from that landing over the ocean.
"raw" version: https://www.youtube.com/watch?v=7m8H8OlJ3o8
"cleaned up" version (it's really not much better): https://www.youtube.com/watch?v=er66BActC4E
As far as I can tell, it's showing the last few seconds, as it fires up the engines for the final time as it landed on the ocean. Don't get your hopes up for any better quality; the craft itself wasn't able to be recovered (it sank long before the recovery craft was able to get there), so any onboard memory of the video is gone.

Damn. Is it still a success if it sank?
