I’m in a debunking mood today, probably brought on by the seasonal “double Moon hoax” that raises its oh-so-wrong head every August. (Read more on that nonsense here.) So here’s one more thing to say “NO” to: giant alien cave crabs on Mars.
Apparently there’d been some buzz recently in the “space woo” circles online over an image acquired by NASA’s Curiosity rover showing an exposed rock outcrop on Mars. In the image, tucked into a corner between a couple of larger rocks, is an oddly-shaped… thing… that some of the more “open-minded” (sarcasm intended) viewers have claimed is an alien organism, not unlike some that have made appearances in various sci-fi films over the years.
I’ve included the original Mastcam image above with the object in question outlined and “enhanced” on the left. Is this indisputable evidence of tentacled cave dwellers on the Red Planet? Hardly.
No, no, no…a thousand times NO: Mars will not become a “second Moon” in the sky on August 27. It won’t this year, it didn’t last year, and it didn’t in the past dozen years since this silly yet strangely perennial cyber-legend (yes I just used the prefix “cyber”) first started circulating on teh interwebz. I don’t know why it keeps rising from the e-dead every year, some years more omnipresently than others, but the bottom line is it simply won’t happen. Not this time, not ever… the Solar System just doesn’t work that way. (And good thing too!)
One of the biggest clues to finding evidence of life on Mars – past or present – has been the existence of methane, an organic compound that is the principal component of natural gas here on Earth. Methane can arise via both biological and non-biological processes, but in both cases it can be used as “food” for living organisms (known as methanotrophs.) Methane has been detected on Mars today by both orbiting spacecraft and rovers on the ground, and now researchers have identified methane within meteorites found on Earth that originated from the Red Planet.
Do you love to look up at the Moon? Well so does NASA’s Curiosity rover! Feel free to correct me if I’m wrong (I have not confirmed this) but this appears to be an image of Phobos, the larger of Mars’ two small moons, imaged by Curiosity’s Mastcam on mission Sol 1002 (June 1, 2015). I spotted it while looking though some raw images on JPL’s MSL mission page.
Phobos is a very small world, only about 16 miles (26 km) across, and orbits Mars at 5,840 miles (9,400 km) altitude. Curiosity has imaged it before, once actually crossing in front of the Sun during an eclipse event on Aug. 20, 2013.
Both Phobos and its smaller, more distant sibling Deimos have been imaged together by Curiosity as well, during an occultation on Aug. 1, 2013. See an animation of those observations here.
Planned observations of Phobos help scientists more precisely determine its orbit.
See a color image of Phobos acquired by the HiRISE camera aboard Mars Reconnaissance Orbiter here.
The first trailer for The Martian is out, a new film by Ridley Scott based on the best-selling novel of the same name by Andy Weir. (If you haven’t read The Martian you really must check it out – it’s a fantastic “science-reality” adventure about one stranded astronaut’s struggle to survive on Mars and NASA’s attempt to get him back.) After watching this I’m even more excited about it – I think this could spark more space survival movies (à la Gravity) that don’t need to depend on over-imaginative science concepts or alien civilizations as story hooks – real survival on other planets will be dramatic enough!
The Martian will open in U.S. theaters on
November 25 October 2!!! The studio switched its opening day to avoid competition with Disney’s Good Dinosaur and the second Hunger Games installment. I’ve got no problem with that! (Source)

There was a bit of a press frenzy last week surrounding the idea of a global flag that could be used in instances of human exploration off our planet, where international collaboration could be celebrated and memorialized on alien worlds rather than the more old-timey nationalistic space races with various countries’ flags dotting remote landscapes across the Solar System. To this end Oskar Pernefeldt, a design student at Beckmans College of Design in Stockholm, Sweden, created a proposal for a “Flag for Planet Earth” as a senior project – a flag that could be proudly planted and worn by future astronauts as we expand our presence through space. Various news sites picked up the story, as seen in this article on Verge.com by Jacob Kastrenakes – and it spread from there as “this is the flag we’ll plant” when we land on Mars, an asteroid, the Moon (again), Europa, etc., etc.
The question is: will it really? And more importantly, would we even want it to be? I, for one, would not.
