Magnetic memories of a metal world

Research deciphering the hidden magnetic messages encoded in a rare group of meteorites has helped secure nearly half a billion dollars of NASA funding for a journey to their parent asteroid -- the only known place in the solar system where scientists can examine directly what is probably a metallic core.

NASA's Curiosity rover has a pet rock on Mars

Added: 23.06.2017 21:57 | 0 views | 0 comments


Mars is probably a pretty lonely place.  The red planet is littered with rusty red rocks and, as far as we know, devoid of any kind of life. But even so, rovers still roam the surface of the world on humanity's behalf, making their solitary treks along previously unexplored paths.  And sometimes, they make friends.  SEE ALSO: NASA photo captures the loneliness of the Mars Curiosity rover NASA's Curiosity rover — which has been exploring the red planet's Gale Crater since 2012 — appears to have a little pet rock caught in one of its wheels.  The rock got stuck in the right front wheel at some point in the last couple weeks, but scientists aren't exactly sure when it started hitching a ride because the rover doesn't snap photos of its wheels every day.

Lakdawalla said that NASA and other interested folks back on Earth keep an eye on Curiosity's wheels and the rocks that might pop up in them as it roams the Martian surface. Scientists also spotted another rock, which appeared in that same right front wheel starting in January and disappearing by April, according to Ashwin Vasavada, a Curiosity project scientist.  The current pet rock was seen in photos taken on Sol (Mars day) 1729 and 1730, which translates to June 17 and June 18 on Earth.  "We don’t exactly know how the rocks get in the wheels, but it’s likely that they can hop in as the wheels (and heavy rover) break rocks and sink into the soil around loose rocks," Vasavada said via email. As for the rock's effect on Curiosity's wheels, it seems to be pretty benign.  MARS FACT: All rocks on Mars are freeloading stowaways. pic.twitter.com/m8nSdVUXE4 — SarcasticRover (@SarcasticRover) June 20, 2017 The rocks are small and relatively soft, Vasavada said, so they shouldn't pose too much of an issue to the long-running rover's movements. However, it's always possible that something unexpected could happen.  "There are some bad scenarios, such as when a rock gets jammed and makes a larger hole in a wheel, or if a rock interferes with some cables that run to the wheel motors," Vasavada said. "But we don’t think those are credible problems with these small rocks." Scientists have Curiosity take these photos of its wheels to keep an eye on any holes that have developed in the rover's machinery.  The holes in Curiosity's wheels are a sign of the wear and tear the rover has taken on during its years of work on the red planet, but for the moment, the worn wheels are still functioning well.  And hey, at least Curiosity has a friend.

Can you spot the Curiosity rover in this photo of Mars?

NASA's Curiosity rover has delivered some seriously stellar views of Mars to us back on Earth, but it's easy to forget that the dusty, durable vehicle spends a lot of its time driving to various locations of scientific importance. Crawling over rocks and navigating never-before-seen peaks and valleys, the trusty bot just keeps on truckin'. This week, NASA delivered a photo that perfectly encapsulates Curiosity's tiresome journey, but you might miss the rover at first glance.

The photo, taken by NASA's Mars Reconnaissance Orbiter, captures the Curiosity rover as it trudges over a seemingly endless sea of rocky, lifeless terrain. The image, which has been color-enhanced so that you actually have a chance of picking out the rover hidden among the weathered rocks and sand.
Can you see it? It's a bit hard to make out, but that tiny blue dot in the very center is Curiosity, clawing along on the martian landscape on its way to a new destination. In the photo, the vehicle is headed uphill on Mount Sharp, towards Vera Rubin Ridge, where Curiosity investigated rock formations.
It's kind of crazy to think that this very thing — scraping its wheels on dusty rocks, taking samples, and snapping photos — is what the rover has been doing every day for the past five years or so. And with its plutonium power supply rated to last  (albeit with a decrease in overall output), it could be doing it for the better part of another decade, if things work out well.
