qxcontinuum Posted November 13, 2013 #1 Share Posted November 13, 2013 (edited) Interesting structure on Mars , another mystery . The object is raised since has gotten a shadow in the left hand side and capturing sun reflection on to the left. 1880 meters long and 550 wide. Coordinates 13°19'45.38"N 115°34'14.39"W Edited November 13, 2013 by qxcontinuum Link to comment Share on other sites More sharing options...
psyche101 Posted November 13, 2013 #2 Share Posted November 13, 2013 Mars has it's own Uluru! Super Cool!!!! Link to comment Share on other sites More sharing options...
qxcontinuum Posted November 13, 2013 Author #3 Share Posted November 13, 2013 (edited) quite symmetrical isn't it? Consequently I am reading the following article about the mystery of methane found in the previous missions and that is no longer there...which indicated past existence of life ... what could have happen? According to the specialists methane can stay up to 300 years in the martian atmosphere. Since before was there and now is not...could be that 300 years ago there was life on Mars ? http://www.space.com/22862-mars-methane-missing-curiosity-rover.html Edited November 13, 2013 by qxcontinuum Link to comment Share on other sites More sharing options...
JesseCuster Posted November 13, 2013 #4 Share Posted November 13, 2013 Actually, I'm pretty sure that's a depression and not a raised area. Look at how the craters around it are illuminated by the sun. They are all lit up as if the sun is shining from the west with the west of the craters in shadow and the eastern rim in bright light. For example, take a look at the crater directly north of the object. The sun is clearly shining from the west and the whole area on Google Mars is from the same image from the ESA's Mars Express orbiter. I'm going to have a hunt for better images but I'm not having any luck at the moment. 3 Link to comment Share on other sites More sharing options...

I really want an Uluru on Mars but, I am hoping we Aussies can make some sort of claim to that......... 1 Link to comment Share on other sites More sharing options...

By comparison, a cow produces about 100Kgs of Methane in a year. Link to comment Share on other sites More sharing options...

JesseCuster Posted November 13, 2013 #8 Share Posted November 13, 2013 (edited) Yeah, seems to be a depression of some sort, not some sort of rocky protrusion. edit: It's clearer from a wider view of the area. The shadows and reflections in the craters are clearly from a sun to the west (left) of the area so the thing in question is clearly some sort of sunken depression.

seeder Posted November 13, 2013 #11 Share Posted November 13, 2013 How does a depression cast a shadow. That looks like a shadow to me Look at the craters around it, all have shadows on the left - and craters are of course, depressions. Either that or its a mother ship surrounded by saucers Link to comment Share on other sites More sharing options...
JesseCuster Posted November 13, 2013 #12 Share Posted November 13, 2013 How does a depression cast a shadow. That looks like a shadow to me It is a shadow. Here's a picture of meteor crater in Arizona. One side of it is in shadow yet it's a depression, not a hill. 3 Link to comment Share on other sites More sharing options...
Space Commander Travis Posted November 13, 2013 #13 Share Posted November 13, 2013 So what is it then>? Obviously something must have gone in there are quite a speed to excavate a crater that big. And are you trying to tell me (chortle) that a Meteorite would make a crater like that? That's far too regular. It's got to be something artificial. 1 Link to comment Share on other sites More sharing options...

Hazzard Posted November 13, 2013 #20 Share Posted November 13, 2013 (edited) A subterranean cave perhaps? Nah,... I think its more likely that it was carved out by a meteor striking the planet at a shallow angle. Edited November 13, 2013 by Hazzard Link to comment Share on other sites More sharing options...

Possibly, though I don't see any clear indication of ejecta from an impact. Is there an image showing a larger portion of the surrounding area anywhere?

It's only "got to be something artificial" because you're refusing to use any form of critical thinking skills. And how can you tell how big it is?? Its obviously an impression made at a shallow angle. Meaning something came in through the atmosphere at great speed and hit the ground. Like a meteor. Which is a completely satisfactory explanation for what we can see, whereas saying "its artificial" doesn't explain what we can see. 1 Link to comment Share on other sites More sharing options...

There doesn't have to be, something quite small going very fast would carve a hole in the ground without throwing too much out onto the surrounding area.

That's true though the object appears to be around 2 kilometers long (depending on how accurate the line tool is in Google Mars). I'd think an impact crater of such a size would throw something out though I'm certainly no expert on such matters.
