Ice Depth Varies Across the Surface of Mars

NASA’s Mars Odyssey has performed a detailed analysis of water ice deposits beneath the surface of Mars, and found they vary greatly in depth. In other words, when future spacecraft land on the surface of Mars and start digging to reach these icy deposits, they might hit paydirt right away, or have to drill and drill and drill.

Mars Odyssey is equipped with Thermal Emission Imaging System as part of its suite of scientific instruments. This camera allows the spacecraft to detect subtle differences in temperature on the Martian surface. Regions which have ice close to the surface retain heat differently than regions where the ice layer is much deeper. This allows scientists to built up a map of ice depth.

In some cases, the ice will only be a few centimetres beneath the Martian surface, while in other situations, it could be many metres deep.

Future spacecraft, such as the Phoenix Mars Lander, may need to dig deep to find the ice.

Spirit Finds an Ancient Volcanic Explosion

NASA’s Spirit rover has turned up evidence that there was once a massive volcanic explosion in the region it’s currently exploring on the surface of Mars. The region is called “Home Plate”, and it’s an plateau of layered bedrock approximately 2 metres (6 feet) high in Columbia Hills.

Spirit found that that area around Home Plate is mostly basaltic rocks, which are created during very fast lava flows. When the lava makes contact with liquid water, it can explode. So the rocks on Home Plate appear to have been created in this environment of lava and liquid water. More good news for the search for evidence of past liquid water on Mars.

One of the strongest pieces of evidence is what the researchers are calling “bomb sag”. When the lava and water meet, the explosion hurls chunks of rock into the air. One of these pieces of shrapnel came back down and lodged in softer deposits.

It’s hard to believe, but Spirit and Opportunity are now in their 4th year of exploring Mars. NASA reports they’re both in good health and continuing to return science data.

Rosetta Gets an Amazing View as it Skims Past Mars

This absolutely stunning photograph was taken by ESA’s Rosetta spacecraft during its recent flyby past Mars on Saturday. In order to receive a gravity boost from the planet, the spacecraft flew past only 1,000 km above the surface.

The Search Continues for Beagle 2

Since its disappearance in December 2003, scientists have continued the search for Europe’s Beagle 2 lander. Although they’ve lost hope in regaining contact, at least they might be able to discover what happened to it and learn from their mistakes.

Martian Explorers Should Be Looking for Fossils

Instead of just looking for current life on Mars, Arizona State University professor Jack Farmer thinks that future missions should also be looking for ancient fossils on the Red Planet. In fact, he thinks they might be easier to find.

Rosetta Approaches its Mars Flyby

If you’re waiting for the Rosetta mission to really pay off, you’re going to need a lot of patience. The ESA spacecraft isn’t due to meet up with its target, Comet 67P Churyumov Gerasimenko, until 2014. But there’s a little science coming on February 25th, when the spacecraft swings by Mars.

Spacecraft Finds Evidence of Underground Fluids on Mars

Here’s an interesting new result from NASA’s Mars Reconnaissance Orbiter. Scientists announced today that the spacecraft has turned up evidence that some kind of liquid or gas once flowed beneath the surface of Mars.

Imaging Problems for Mars Reconnaissance Orbiter

Although NASA’s Mars Reconnaissance Orbiter is about to break the record for science data returned from the Red Planet, it’s got a couple of problems that could be getting worse.

Martian Probes Need to Dig Deeper

If they want to find life on Mars, future explorers will need to dig down deep under the surface. This is according to new research published by University College London Researcher Lewis Dartnell.

Looking at Jupiter, From Mars

Guess who took this picture of Jupiter? Hubble? Keck? A well equipped amateur here on Earth? Nope, it was taken by the HiRISE camera on board the Mars Reconnaissance Orbiter. The picture was taken from orbit around Mars.
