Meteorite? Rover antics? Elvis?

All of these theories are on the table when it comes to the mysterious rock that has appeared on Mars. When scientists working with the Mars Opportunity Rover compared two photos — one taken in late December and one on January 8 — they noticed the rock, which apparently appeared right in front of the rover at some point within a 12-day window.

The rover’s lead scientist, Steve Squyres, announced the finding at a 10-year anniversary event hosted by NASA’s Jet Propulsion Laboratory, celebrating a decade of roving on the red planet: “It’s about the size of a jelly doughnut. It was a total surprise, we were like ‘wait a second, that wasn’t there before, it can’t be right. Oh my god! It wasn’t there before!’ We were absolutely startled.”

Pluto may not be a full-fledged planet anymore, but that doesn’t mean we’re not interested in checking it out, even if it is quite a hike. It’s about 3 billion miles, one way, if you were wondering. NASA’s New Horizons spacecraft set off for the dwarf planet back in 2006, and now that it’s 2014 we can finally say that next year, we’ll have our first close-up glimpse of the gatekeeper to our Solar System.

Last year, New Horizons’ telescopic camera LORRI (Long Range Reconnaissance Imager) got its first image of Charon, Pluton’s largest moon. You can see it just to the upper left of Pluto, which is the bright spot in the middle. But don’t worry, the images will get better as the craft gets closer. When this was taken, New Horizons was still 550 million miles away. In the mean time check out the first images of Charon from 1978 when it was first discovered.

I’m not sure if you knew that the International Space Station had a pre-planned death date. Maybe that’s being melodramatic. Let’s call it decommissioning and deorbiting. Whatever name you slap on it, the ISS’s final days were planned for 2020. While there are only a handful of people, robots, and private companies who will be directly affected when facility powers down, the significance and symbolism loom large. The ISS is a symbol of cosmic collaboration, as well as the first step of the realization of the dream that people will one day live and work in space. So let’s all celebrate because the station just received a four-year extension, and will be in service until 2024. If nothing else, that’s four more years of Chris Hadfield videos.

The Obama administration announced the plan to keep the ISS running until 2024, although obviously the current President will be long out of office by then and whoever comes next could potentially reverse that decision. But the next Chief of Staff is unlikely to do so, and not because he or she is a fan of the station, not only because the ISS cost about $100 billion to make and has prompted over 100 rocket launches and spacewalks, but also because getting it down safely is an undertaking.

There’s a very good chance you’re familiar with the nearly tragic events surrounding NASA’s famed Apollo 13 mission, and a slightly lesser chance you’ve watched Ron Howard’s solid (if dramatically overbearing) feature film of the same name, in which an AIDS-ridden Tom Hanks stoically saves the day with a volleyball named Wilson. (It’s been a while since I’ve seen it, so I may have fudged the details.) In any case, there’s no possible way Hollywood could have properly conveyed the severity of the events, regardless of their sound intentions. So now we have the video above, called “As It Happened,” which is the latest in a line of videos on the fabulous lunarmodule5 YouTube page, where the entire Apollo 13 mission, from launch to splashdown, is being archived for easy public consumption. Well, easy assuming you don’t easily freak out listening to would-be disasters as they’re happening.

Jupiter is set to give Mars and Saturn a run for their money when it comes to being the most talked-about planet in the coming years. The news that Jupiter’s moon Europa contains water vapor plumes helped solidify the Solar System’s biggest planet as a particularly important exploration target, especially when it comes to the search for life. A number of missions, including Juno, which is scheduled to arrive in 2016, have Jupiter in their sights, including the ESA’s JUICE (JUpiter ICy moon Explorer) probe, which is due to launch in 2022. Now it seems that Russia will join the fun, presumably by linking up with the JUICE mission by sending a probe to explore Jupiter’s moon Ganymede.

Robots in space — two great tastes that taste great together. They might go to Mars ahead of the humans to set up facilities, 3-D printed robotic spiders might build spacecraft, and robots might make isolated astronauts less lonely. Yet another robotics advancement at NASA pairs humans and robots, allowing humans to control the actions of robotic counterparts using a good ol’ Microsoft Kinect and something called the Oculus Rift.

The Kinect sensor provides the position tracking, while the Oculus Rift virtual reality headset allows for rotational tracking and the first-person experience one gets when playing a game in virtual reality. When the user has the view he needs, he can perform tasks which control the real-time movements of robotic arm. NASA has been using a JACO robotic arm developed by Kinova, a Canadian company that specializes in rehabilitation and research. The arm has three fingers, six degrees of freedom, and is designed to represent a “new generation of lightweight portable robotic manipulators.”
