Cold as hell and no place to raise your kids, the surface of Mars today is a quite inhospitable place for any forms of life we know of. But that wasn’t always the case – billions of years ago Mars may have been a lot more like Earth, with a magnetic field, a much denser atmosphere, lakes and even an ocean on its surface where life could have not just developed but thrived. And in Curiosity’s hunt for any remaining evidence of that ancient utopia, the rover has identified a key ingredient: nitrates contained within the surface rocks of Gale Crater.
Although it’s not thought that the nitrates were created by organisms currently living on Mars it’s yet another indication that the environment of Gale Crater was once a place where life could have existed, joining the rover’s previous discoveries of traces of water and sediment deposited by ancient rivers.
“Finding a biochemically accessible form of nitrogen is more support for the ancient Martian environment at Gale Crater being habitable,” said Jennifer Stern of NASA’s Goddard Space Flight Center, lead author of the research team.
The first attempt by ESA and Rosetta to hear back from Philae has turned up only radio silence – but that doesn’t necessarily mean the lander is on permanent shutdown. It may just be that it’s still too cold and dark where Philae is to have sufficiently warmed up its components for reactivation.
“It was a very early attempt; we will repeat this process until we receive a response from Philae,” said DLR (Germany’s Aerospace agency) Project Manager Stephan Ulamec. “We have to be patient.”
After landing in an as yet unconfirmed location on comet 67P on November 12, 2014, Philae performed all of its primary science tasks before running out of battery power and entering a hibernation “safe” mode. Its reawakening is anticipated by mission engineers as the comet gets closer to the Sun over the next several months.
The suffix “-gate” is often added to words to create a meaning of conspiracy or public debacle, à la the 1972 Watergate scandal that destroyed Nixon’s term as U.S. president, and we might soon be referring to this as “Marsgate” – the allegations of MarsOne of illegitimacy and fraudulent (or at the very least sketchy) practices by Medium.com reporter Elmo Keep and her contact Dr. Joseph Roche. While Keep and Roche – the latter of whom was chosen as a finalist in the latest round of candidate selections for a future one-way trip to Mars – are certainly not alone in their doubtfulness of the Dutch nonprofit company’s ability to actually set up a human colony on Mars over the next decade, their March 17 exposé article has certainly helped to position MarsOne directly under the burning spotlight of public skepticism (a place some say it should have been since the very beginning.)
Not to let such bad publicity remain blatantly unanswered, MarsOne CEO Bas Lansdorp has published a video interview in which he responds to the criticisms brought up by Keep and Roche. One thing Lansdorp does note is that there has been a delay of two years (already) to the mission timeline, which now puts the first crew’s boots on red ground in 2029 instead of 2027. Lansdorp openly asserts that they have a development team and contracts, and progress will be made.
“The recent bad press about MarsOne was caused to a large extent by an article on Medium.com by Elmo Keep, and that article contains a lot of things that simply are not true.”
– Bas Lansdorp, MarsOne CEO
Of course words aren’t rocketships or habitation modules and anything can be said in an interview. But this is the public response to a public challenge – not likely the first to come, either – and so it remains to be seen where it all goes from here.*
Watch the video interview above, and read more about this week’s Marsgate here.
*One thing that mustn’t be allowed to develop is a public perception of Mars as a human destination to be intrinsically unachievable. MarsOne is not NASA or ESA or any other government space agency (or even SpaceX); if MarsOne fails it won’t be because of Mars or indicative of human capability as a whole. Hopefully if it starts to go that way, Lansdorp will have the good sense and decency to shut it all down before anyone gets hurt.
Only a day after skywatchers in mid- to upper-latitudes around the world were treated to a particularly energetic display of auroras on the night of March 17 as a result of an intense geomagnetic storm, researchers from the University of Colorado announced findings from NASA’s MAVEN mission of auroral action observed on Mars – although in invisible ultraviolet wavelengths rather than visible light.
Obviously this is a totally-for-fun sci-fi video, but what a video! Created by Oscar-nominated Irish filmmaker Ruairi Robinson, it shows fleets of very industrial-looking fighter skiffs hunting giant flying eels through the skies of some very cloudy planet… the first thought that came to my mind was Titan! (Although Titan is more hazy than cloudy but that’s just getting nitpicky.) Check out the video above… if this ever becomes a feature-length film I know I’ll be buying a ticket for sure.

UPDATE 3/23: This proof-of-concept short may become a feature length movie, thanks to District 9 director Neill Blomkamp and X-Men: Days of Future Past producer Simon Kinberg… and also to all the people on the ‘net who have been raving about it! Read more on The Verge here.
After more than nine years of traveling through space the New Horizons spacecraft is now in the home stretch of its journey, with less than 120 days and 143 million kilometers to go before it makes its historic flyby of the Pluto system on July 14. It will be the first time we get a good close-up look at the distant world which had for over seven decades held reign over the frozen edges of our Solar System as the outermost planet, much like its namesake governed the cold darkness of the mythological Greek underworld.
Discovered on February 18, 1930, the ninth planet Pluto lost its “full” planetary status in August 2006 as the result of a highly-contested decision by the International Astronomical Union (IAU) to create a new class of “dwarf planets,” of which Pluto, Ceres, and the then-recently-discovered Eris became charter members. Seven months after New Horizons launched, the edict did not sit well with both many members of the planetary science community and the public, who were suddenly informed that little Pluto just didn’t measure up and had to be let go… nothing serious, right?
Wrong. It was a serious scientific issue for many people, and especially for Dr. Alan Stern, Associate Vice President of Space Science and Engineering at the Southwest Research Institute in Boulder, CO and principal investigator of New Horizons. And understandably so – Dr. Stern’s planetary exploration mission is on its way to Pluto after all, and what it’s expected to encounter is far more complex than what’s implied by the diminutive moniker of “dwarf planet” (which, oddly enough, was coined by Stern himself in 1990.)
I had a change to talk briefly with Dr. Stern on Friday, March 13 – which, incidentally, was the 85th anniversary of Pluto’s first announcement to the world – and got some insight from him on the mission and what we can expect from the upcoming flyby, as well as his views on the whole “planet/dwarf planet” thing. (And yes, it certainly does still matter!)
