7th Graders Find Large Cave On Mars

timothy posted more than 4 years ago | from the ok-now-rhyme-something-with-uranus dept.

Mars 139

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."

Re:Can you be the first to define "crowd-sourcing" (-1, Troll)

Slavery is independent of compensation. Most slaves in the American south, for instance, were paid a daily wage. That's why, after many years of work, some of them could buy their freedom and become freemen.

Many of the early freemen helped create the Underground Railway, to help slaves escape. After all, the problem itself wasn't the compensation they received, which was actually quite good for the time, given that it included housing, food, and money. The problem was that they couldn't move between employers, or choose to not work, because of the state laws at the time.

And yes, this incident today is still a form of slavery. Children in our public schools do not have a choice about whether or not they want to attend. Attendance is compulsory throughout the US, as is partaking in school activities as dictated by the curriculum and teachers.

I wonder what an 18th century slave in the American south would think of that comparison..

How about jury duty, is that also slavery? I'm sure all those people picking cotton were just thankful they didn't have to sit in a classroom or jury box all day. Imagine the horror.

Re:Just kidding, folks. (1)

Dishevel (1105119) | more than 4 years ago | (#32670372)

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 illuminate part of the bottom of the cave. Therefore since they see no bottom it must be deeper than the minimum.

Well, if you look carefully, you can see two vaguely hand-shaped rock formations to either side of the cave. Scientists have used this information to search for similar images for the purpose of comparison, and have thus come to the conclusion that the cave is approximately "ohgodmyeyes" deep.

Re:Just kidding, folks. (1)

John Meacham (1112) | more than 4 years ago | (#32672016)

Presumably they used one of the other dozen or so scientific instruments in orbit around mars to examine the site. The image they showed us on the site was just the one the 7th graders were examining when they found the cave.

Simple (somewhat) ... take two pictures at different times of the day. See how much the shadow / dark spot changes of the walls. Assuming vertical (or nearly so) walls then it's (somewhat) a math problem...

Re:Just kidding, folks. (1)

clone53421 (1310749) | more than 4 years ago | (#32670576)

Assuming vertical wall, you won’t be able to see them. You’re looking down.

Plus, the camera is using thermal imaging, so a moving shadow wouldn’t show up well.

With any spheroid looking down unless you're directly beneath the camera there will be angled views.

A "cave" is an underground chamber.

Besides, if there was no gravity which side would be the ceiling? (I know Mars has gravity, I'm just pointing out the silliness of suggesting something need a "roof" to be a cave)

Re:Just kidding, folks. (1)

From TFA, what they've found is a hole in what is believed to be the roof of a hollowed out lava tube, ie cave.

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.

You see the lumps on the surface next to it, note their hight and size, find the length of their shadow, and then use that to find that according to the angle of the light, if it were less deep than what they say, there would be light on the bottom.

Apparently they want a closer look:

The students have submitted their site as a candidate for imaging by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. HiRISE can image the surface at about 30 centimeters (12 inches) per pixel, which may allow a look inside the hole in the ground.

With a resolution of 0.3 meters... I hope they share their results if they are able to get the site imaged.

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.

Tekfactory (937086) | more than 4 years ago | (#32670240)

If you read TFA, the kids were trying to find Lava Tubes around Pavonis Mons, a volcano on Mars.

It seems to me that the forces of vulcanism, pushing up lava with only 1/3 gravity MIGHT cause them to form differently from those on Earth, which is why Olympus Mons is much taller than any volcano here.

There is a cave found recently in Mexico with Crystal formations unlike anything ever seen before, outside of that I don't know how much interesting stuff there still is in caves on Earth.

I've been to Mammoth Cave in Kentucky, and none of the caves there are 5-600 feet wide, tall, or anything.

I remember 8th grade AP Science and we never did anything this cool, although in 7th grade we were programming TRS-80s and Apple IIs.

I kinda suspect that this is a function of the teacher's willingness to reach out to the university and actively participate in the science than it is any kind of sign of the times.

I would wager that most 7th grade classes still look at the cells in an onion skin or whatnot.

I further wager that 25 years ago there was a 7th grade science class designing experiments for the STS-51 (Challenger) flight, just no /. to report on it.

The border between local and state/national government is a fine one to tread. On one side you have local control over services and disparity between the more and less affluent areas, on the other you have evenly distributed resources and the problems that a central beaurocracy can bring. That is merely on observation, but personally I feel that the curriculum isn't the only thing that should be nationalised.

By reading this I just realized how different the world view, and especially personal living history, has been for people who were in school without the Internet.

Today we have boundless amount of information readily available for every kid in school age. Well, since every kid born after 1984. I was lucky to be in the first generation that got computers with Internet to school in Finland.

Text based interfaces were there before, but having a proper GUI to the information-- texts with proper layout and pictures, for example, made all the difference.

I can't say I couldn't live without Internet, since I have never experienced periods of over two months without _any_ contact to it.

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.

The fact that the budget cuts are this bad, or the fact that all those years of post-HS schooling and student loans these scientist did for all their education is mentally around the level of a 7th's grader in the eyes of the government.

They didn't cut the budget.

Did you know there is a space plane in orbit? how about the many,many other project going on?

Parts of constellation got scrapped, and for good reason.

They didn't cut the budget.

The parts dealing with going to the moon did. [slashdot.org] Though not all of it was cut and some parts did get more money. Seems like the joke went over a few peoples heads (seeing how it was marked down...)

The total budget is still larger, and thank goodness they're getting rid of Operation Lets-Repeat-Apollo-And-Act-Like-That-Means-Something which was preventing other actually new and interesting things from being accomplished.

BTW I got that you were joking, but it wasn't funny. It seems like there could be a joke premised on NASA hiring 7th graders, so maybe try working on it. Or not.

Did you know NASA doesn't have a space plane in orbit?

That'd be the Air Force, whose budget is handled just a tiny bit differently...

It's not a cave (1)

Just looking at the pictures one can plainly see a string of sharp edged depressions (or pits) having a shadow on the left rim. The circled area of this image is simply another one of those depressions which happens to be slightly smaller in diameter than the width of the shadow. It is therefore obvious that this is just another one of those depressions. In order to be a cave it would need to travel UNDERNEATH the ground.

I liked Mars better in the old days, when we still expected to find green women or for an armada of alien ships to possibly be headed our way. A little hot-cold red rock with some dry craters isn't nearly as interesting.

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.

Y'know what I find frustratingly unfair about virtually ALL Internet comment-posting systems?

They all have a "submit" button, but there's never a "dominate" button ...

Cottonwood? Really? (1)

I live near Cottonwood, and I never suspected they taught anything beyond logging, ranching and truck driving.

Great job, kids. I really have to reconsider Tehama County schools.

Wow.

One of them hopefully knows something about web design and can do better than this [k12.ca.us]
