7th Graders Find Large Cave On Mars

Posted by timothy on from the ok-now-rhyme-something-with-uranus dept.

A newly discovered cave on Mars was found as the result of an interesting crowdsourcing project. As EMB Numbers writes, "CNET news reports that 'the science class from Evergreen Middle School in Cottonwood, Calif., found the opening while working on a research project with the Mars Space Flight Facility run out of Arizona State University in Tempe. ... The students examined more than 200 images of Mars taken with the Thermal Emission Imaging System (Themis), an instrument on NASA's Mars Odyssey orbiter.' The only other similar opening near the volcano was found in 2007, when Glen Cushing, a scientist with the US Geological Survey, published a research paper on the surface anomalies. The opening is estimated to be 620 by 520 feet and the hole to be at least 380 feet deep."

    I looked at the pictures, and it seems that they had a bug on the lens.

    In all seriousness, though, I wonder how they can determine the depth of the hole, just from the surface characteristics?

      They say "at least"; I'd take that to mean "if it was any less deep than that, we'd see some trace of the bottom".

      Why do they call a vertical hole a cave?
      Don't caves typically have roof/ceilings?
      Its just a hole, lava vent.

      Easy, you know the distance and the angle of the lens so you can calculate the diameter.

      You also know the angle of the sun at the time of the photo and measure the lit (or unlit) area below the hole, that'll give you an approximation of the depth.

      They were using thermal imaging, not visible light.

      ok, to revise then:

      I would think that by using the image to get the angle of the sun striking the surface of Mars that they could say that if it was any shallower than that the light from the sun would Heat Up part of the bottom of the cave. Therefore since they see no heat from the bottom it must be deeper than the minimum.

    When I was in grade 7 we learned about nothing even remotely as interesting as this. I think we looked at plant cells under a microscope.

    It is pretty amazing that students can work with data like this, with computers and tools that enable it. Makes me wish I could go back to school and work on some of the stuff they teach in basic courses, particularly in high school.

    Kids these days! (are damned lucky!)

    In my day, a fieldtrip consisted of nothing more than going outside -- in a field. The only caves we saw were the ones we had school in, and those were shared with the grizzly bears. If you've never seen your best friend's head get popped like a grape in the jaws of a grizzly, you've got it easy. It wasn't all bad though. Whenever we got a new transfer student, we'd convince them to yell into the cave really loud to "scare away the bats." Man, that was hilarious.

    Anyway, yeah.. Mars.

    Since it's facing us, that means it's on the side of the planet and as such, it is a cave. If it was on top of the planet, it would be a hole. Do try to keep up.

    That's no cave. That's the opening to the underground cannon the Martians used to fire their invasion cylinders at Earth during the opposition of the last years of the 19th century.
