Mercury Turns Out To Be a Weird Little World

sighted writes "The robotic spacecraft MESSENGER, now orbiting the first planet, has found new findings odd features on its surface, including unexplained, blueish 'hollows' that may be actively forming today. The findings will be published this week in Science. One scientist said, 'The conventional wisdom was that Mercury is just like the Moon. But from its vantage point in orbit, MESSENGER is showing us that Mercury is radically different from the Moon in just about every way we can measure.'" As you might expect, National Geographic has beautiful imagery to go along with the story.

      Maybe I'm missing something, but how can this be? After all, I can go to CostCo and buy a really nice DSLR digital camera for a few hundred dollars, take it just about anywhere, click some photos, and those images when viewed on a decent monitor or printed out will look pretty close to what that place looked liked to my own eyes. Obviously, there's a few minor differences in exactly what wavelengths my eyes can see, and how sensitive they are at various wavelengths, compared to the camera's image sensor, but it's close enough.

      So why can't you take that same camera (maybe with a clear protective case like you'd use for underwater photography), send it to another planet, and take photos there showing what the place would look like to human eyes (the same as if a human actually traveled there and looked at the place with his own eyes)?

      I suspect there's no reason you can't do this, and the only reason they don't is because it would simply be too boring-looking (e.g., everything on Mars would just look red, everything on Venus would just look yellow (until the camera melted from the heat!), everything in most other places would just look gray, etc. So they use image sensors that aren't matched to the human eye at all, and instead are tuned to the environment they'll be used in, so they can get more useful information.

      Spectrometers also reveal substantially higher abundances of sulfur and potassium than previously predicted.

      New data from orbit show a huge expanse of volcanic plains surrounding the north polar region of Mercury. These continuous smooth plains cover more than 6% of the total surface of Mercury.

      Scientists have also discovered vents, measuring up to 25 kilometers (km) (15.5 miles) in length, that appear to be the source of some of the tremendous volumes of very hot lava that have rushed out over the surface of Mercury and eroded the substrate, carving valleys and creating teardrop-shaped ridges in the underlying terrain.

      Now MESSENGER's orbital mission has provided close-up, targeted views of many of these craters. The bright areas are composed of small, shallow, irregularly shaped depressions that are often found in clusters said David T. Blewett, a planetary scientist at the Johns Hopkins University Applied Physics Laboratory (APL) and lead author of one of the Science reports. "The science team adopted the term 'hollows' for these features to distinguish them from other types of pits that are found on Mercury."

      Hollows have been found over a wide range of latitudes and longitudes, suggesting that they are fairly common across Mercury. Many of the depressions have bright interiors and halos, and Blewett says the ones detected so far have a fresh appearance and have not accumulated small impact craters, indicating that they are relatively young.
