If you’re a heavy metal fan then you’ll love this: this shiny, lumpy rock spotted by NASA’s Curiosity rover is made mostly of iron — and came from outer space! Dubbed “Lebanon” it’s a stony iron meteorite, similar to ones found in years past by the Spirit and Opportunity rovers, but is considerably larger than any of the ones they came across. In fact, at 2 meters (6.5 feet) wide, Lebanon is the biggest meteorite ever discovered on Mars!
Sol 669 is here (well, there… on Mars that is…) and that marks the one full year anniversary of Curiosity’s mission exploring Gale Crater! Wait, you say, didn’t Curiosity land on Mars in August of 2012? Shouldn’t we still be approaching the TWO-year anniversary of the MSL mission? Well, yes, here on Earth, but on Mars a year is 1.8808 Earth-years long — that’s 686.9 Earth days to a single Martian year! So from landing day August 5 (August 6 UTC) 2012, 686.9 days Earth days (i.e., one Martian year) later is June 24, 2014 (which it is at the time of this writing, UTC) and thus:
Happy Mars Anniversary, Curiosity!
NASA’s Curiosity rover may be busy exploring the rugged and rocky interior of Gale Crater but it does get a chance to skygaze on occasion. And while looking at the Sun on June 3, 2014 (mission Sol 649) the rover’s Mastcam spotted another member of our Solar System: tiny Mercury, flitting across the Sun’s face.
Silhouetted against the bright disk of the Sun, Mercury barely appears as a hazy blur in the filtered Mastcam image above. But it was moving relatively quickly during the transit and passed the darker smudges of two Earth-sized sunspots over the course of several hours. It was the first time Mercury has ever been imaged from Mars, and also the first time we’ve observed a planet transiting our Sun from another world besides our own.

What were you doing on Sunday night? Whatever it was (and by the way I do hope it was watching Cosmos) about the same time, 59.5 million miles away, NASA’s Curiosity rover was taking her picture on Mars inside Gale Crater! Here’s Curiosity’s latest “selfie,” a mosaic I assembled from about a dozen images acquired with the Mars Hand Lens Imager (MAHLI) instrument on April 27-28, 2014 (Sol 613). Along with Curiosity’s “grinning” face there on the left you can see the 3.5-mile-high Mount Sharp (aka Aeolis Mons) rising in the background.
Doesn’t she look adorable (if a bit dusty)?
Putting this together wasn’t an exact science, so there are plenty of discrepancies where the separate images line up. But that’s okay — the overall effect came out pretty nicely and I’m happy with it. It still a robot on another planet, after all! And until there’s people walking around on Mars, I can’t think of anything cooler than that.
Making a big splash (pun intended) in the space news world today is the report that NASA’s Mars Science Laboratory rover Curiosity has found traces of water in samples of Martian soil! The samples were scooped from an area nicknamed “Rocknest” in October 2012 and analyzed with the SAM instrument suite (read more on that here.)
Now it’s not a lot of water, definitely not a cupful or even remotely resembling what we’d call damp, but it is water — about 2% of the soil particles’ mass contains water molecules, and it’s estimated that this is indicative of the surface material across the entire planet. Obviously the implications of this are huge! (Think: resources for future explorers, for one!)
An outcrop visible as light-toned streaks in the lower center of this image has been chosen as a place for NASA’s Mars rover Curiosity to study for a few days in September 2013. The pause for observations at this area, called “Waypoint 1,” is the first during the rover’s trek of many months from the “Glenelg” area where it worked for the first half of 2013 to an entry point to the lower layers of Mount Sharp aka Aeolis Mons, the towering central peak of Gale Crater.
The pale outcrop is informally named “Darwin.”
Today marks the one (Earth) year anniversary of Curiosity’s landing on Mars, which occurred on at 10:31 p.m PDT August 5 (1:31 p.m. EDT August 6) 2012… hard to believe it’s been a whole year already! But then, with all that the MSL mission has discovered over these past 12 months, it’s also hard to believe it’s only been a year!
To commemorate the occasion, engineers at NASA’s Goddard Space Flight Center have programmed one of Curiosity’s core science tools, SAM (Sample Analysis at Mars), to “sing” happy birthday to Curiosity using its ability to vibrate its sample chamber at various specific frequencies… i.e., make music. Pretty cool!

Congratulations MSL, and here’s to many more happy anniversaries — and discoveries — for Curiosity!
