Opportunity Spots Curious Object On Mars

EhobaX writes "Space.com is reporting that NASA's Opportunity Mars rover has come across an interesting object -- perhaps a meteorite sitting out in the open at Meridiani Planum. Initial data taken by the robot's Mini-Thermal Emission Spectrometer (Mini-TES) is suggestive that the odd-looking "rock" is made of metal."

This is a big deal. You don't find raw metal much on Mars; most of it is tied up with oxygen. Raw metal has many implications: if it is common, it can be a great source of base building. If the metals are rare on Earth as well, and they're common on Mars, they could provide a potential export source. If it is a meteor, and they're common, it could affect our models of how often Mars gets struck by meteors. Since the rock isn't buried, it could provide clues as to how long it's been on Mars, how fast Meridiani Planum is eroding, and give us dataon how metals wear over time on Mars.

Any time you find something you've never found before, it's a big deal. Honestly, to people who've been following the mission, it looked like Opportunity was pretty much wrapping things up. It just left a geological treasure trove and there isn't much more "on the map", so to speak. It's neat to see it continue making nice finds.

For those of you who don't know what TES (Thermal Emission Spectrometer) is, here is some more information. The webpage is quite interesting.

For clarity: That link is to TES, which flies on the Mars Global Surveyor. The instrument on the rovers is called Mini-TES and does similar things.

I work at the lab responsible for both.

It could resaonably be an iron meteorite.

"Iron meteorites", also called "irons", are usually just one big blob of iron-nickel (Fe-Ni) metal, as if it came from a industrial refinery without shaping. The alloy ranges from 5% to 62% nickel from meteorite to meteorite, with an average of 10% nickel. Cobalt averages about 0.5%, and other metals such as the platinum group metals, gallium, and germanium are dissolved in the Fe-Ni metal. (Fe is the chemical symbol for iron.) While most "irons" are pure or nearly pure metal, the technical definition of an "iron" includes metal meteorites with up to 30% mineral inclusions such as sulfides, metal oxides and silicates. The irons represent the cores of former planetoids.
