Seeking Shelter

The exploration rover Opportunity has identified what seems to be another ferrous extraplanetary visitor resting on the sands of Meridiani Plains. The 19-inch-long meteorite, shown here, has been dubbed “Shelter Island” by the MER team. Opportunity’s tire tracks are visible in the upper left. Opportunity spent six weeks in September and October investigating “Block Island”,…

Can’t Catch Me!

Windswept Martian dunes create a somewhat humanoid, running gingerbread-man figure in this image from the HiRISE camera aboard the Mars Reconnaissance Orbiter. The dunes reside within a crater in the southern hemisphere of Mars. This week, the University of Arizona released thousands of new images from their HiRISE (High Resolution Imaging Science Experiment) observations, taken…

Cracking the Surface

Images taken by the Mars Reconnaissance Orbiter and Mars Global Surveyor satellites show dry, cracked surfaces within Martian craters. Previously thought to have been caused by subsurface permafrost contractions, it’s now believed these parched surfaces indicate the remains of dried lake beds. Similar to features found in dry lake beds on Earth, the cracks on…

Gully Gee…

One of thousands of new images released on September 2 from the University of Arizona’s HiRISE project, this amazingly detailed image shows the dramatic effects of erosion on the steep sides of Hale Crater on Mars. Whether or not these channels were caused by liquid water or a dry process is still under investigation. It’s…

A Dusty Sunset

The Spirit rover, still mired in the soft sand, recently took a series of photos showing the sun setting into a dusty Martian sky. I combined the raw images here to create a short animation. Yes, Spirit is still stuck near Home Plate. Its power levels are good but the rover team has not tried…

Martian Lomography

Although not particularly exciting in theme, I like this image a lot for its light and shadow composition. Taken on June 23 by the Spirit rover, this false-color view of the surrounding ground is nicely lit by a setting sun that also creates a glare in the lens. It’s not unlike photos I sometimes get…

Revisiting Victoria

The Mars Reconnaissance Orbiter captured this image of Victoria Crater on July 18, 2009, with the onboard HiRISE high-definition camera. Victoria Crater was the site of the Opportunity rover’s 2006-2007 investigation. Craters like these are great targets for the rover team because the exposed rock along their edges offers valuable information about Mars’ geologic history….

Around the Block

“Block Island”, the recently-discovered meteorite resting on the Martian sand dunes, is shown here in a false-color raw image by the Opportunity rover. Measuring nearly 2 feet across, it is the largest meteorite found so far by the Mars Exploration Rovers. Its metallic surface, pocked and pitted by erosion and its collision course through the…

The Iron Giant

“It’s big,” said Mars Exploration Rover team member Ray Arvidson. And at approximately the size of a beach ball, about 2 feet wide, it is the largest meteorite fragment found so far on Mars. The Opportunity team spotted the rock, now known as “Block Island”, during the rover’s travels across the dunes of Meridiani Planum….

It Came From Outer Space

The Opportunity rover has come across a two-foot-wide rock sitting on the Martian sands that may very well be a meteorite. The rock, nicknamed “Block Island”, was spotted by the Mars Exploration Rover team on July 18. They had the rover reverse course and drive over to it to get a better look. The image…

Shifting Sands

Serpentine dunes etch the polar sands of Mars in this image from the HiRISE camera aboard the Mars Reconnaissance Orbiter. See the original release here. The MRO was 194 miles above the surface when it took this photo. Image: NASA/JPL/University of Arizona

Phoenix’s Sense of Snow

The results are in: Mars has (or had) a favorable environment for life. Microbial life, sure, but life nonetheless. This is according to the results posted in this week’s edition of the journal Science, from the Phoenix Mars polar lander. The data indicates that the region around the lander has subsurface layers of perchlorate, a…
