It happens every time: an asteroid is slated to make a perfectly safe pass by Earth on its route around the Sun, like everyone else, but the tabloid “news” sites take the opportunity to start screaming bloody horror about the upcoming “near miss” and “terrified” NASA scientists etc. etc. It’s awfully tiring and even more predictable than the asteroids’ orbits themselves. I’d usually ignore such things except that they have the unfortunate side effect of actually 1. garnering a lot of attention, at least for a short period of time; and 2. scaring the bejeebers out of people who may not follow real space science news as much as I do. (Which is a lot of people.) So in an attempt to sort out any confusion I’ll say for the record:
There is no need to worry about asteroid 2014 YB35. It will safely pass by Earth on March 27, 2015 at about 4.5 million kilometers, or 2.7 million miles… 11.7 times farther than the Moon.
(And if that sounds like a long way away, that’s because it is.)
This July the New Horizons spacecraft will perform its long-awaited flyby through the Pluto system, capturing unprecedented data and images of the distant icy planet and its companion satellites Charon, Nix, Hydra, Kerberos, and Styx. The first two worlds, in particular, will have their surfaces seen in high-resolution, allowing scientists to observe and map their features for the very first time. But as landforms come into view – craters, mountains, scarps, plains, and who knows what else – what will they be named?
This is where YOU come in.
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.
