The Case for Colonizing Mars

Posted by in categories: materials, space

Mars Is The New World

Among extraterrestrial bodies in our solar system, Mars is singular in that it possesses all the raw materials required to support not only life, but a new branch of human civilization. This uniqueness is illustrated most clearly if we contrast Mars with the Earth’s Moon, the most frequently cited alternative location for extraterrestrial human colonization.

Picture Of ‘Human Bone’ Found On Mars Explained

Posted by in category: space

In recent times it seems an image of a human bone sitting somewhere on Mars has been making its rounds yet again. While we’re not sure why this is happening, there is a story behind this ‘bone’ and the image it was present in.

Now, to kick things off, NO it’s not a human bone. This bone-shaped thing is actually a rock, nothing more and nothing less. While in the photograph it does really look like a bone, that’s just not what it is. Actually, NASA even wrote a small piece on this topic breaking down a bit about how this femur thigh bone looking thing on Mars was a rock and why it was/is the shape that we see in that photograph.

Mars orbiter spots green glow over Red Planet

Posted by in category: space

Turns out the Red Planet is a little more green than we thought. The ExoMars Trace Gas Orbiter (TGO) has detected a tinge of green in the atmosphere, making it the first time this aurora-like glow has been spotted around a planet other than Earth.

Here at home, green glows in the sky are caused by glowing oxygen, excited by collisions with electrons that stream into the atmosphere from solar wind. While aurora are the most dramatic examples, the sky glows almost constantly. At night it can appear green as molecules previously ripped apart by solar winds begin to recombine.

It was predicted that this same effect should be visible around other planets, but it’s hard to spot since the bright surfaces of planets can wash out the color. Now, astronomers from ESA have managed to detect it around Mars for the first time.
