“One small step for (a) water bear, one giant leap for water-dwelling eight-legged segmented micro-animals.” —Teddy Tardigrade
Are you thinking what I’m thinking? Because if you are, you’re thinking that exposing tardigrades to high-energy cosmic rays can only mean one thing: super-tardigrades. From Live Science:
The Israeli spacecraft Beresheet crashed into the moon during a failed landing attempt on April 11. In doing so, it may have strewn the lunar surface with thousands of dehydrated tardigrades, Wired reported yesterday (Aug. 5). Beresheet was a robotic lander. Though it didn’t transport astronauts, it carried human DNA samples, along with the aforementioned tardigrades and 30 million very small digitized pages of information about human society and culture. However, it’s unknown if the archive — and the water bears — survived the explosive impact when Beresheet crashed, according to Wired.

Well, OK, as tough as they are, it’s probably unlikely that those microscopic explorers will re-hydrate any time soon before being hit by high-energy particles that will then endow the tiny guys with Marvel-like superpowers, but it’s nice to dream.
But what are tardigrades? Let’s go back to Mindy’s Live Science article, because her explanation is simply too adorable not to reprint:
Tardigrades, also known as moss piglets, are microscopic creatures measuring between 0.002 and 0.05 inches (0.05 to 1.2 millimeters) long. They have endearingly tubby bodies and eight legs tipped with tiny “hands”; but tardigrades are just as well-known for their near-indestructibility as they are for their unbearable cuteness.
Moss piglets! Or should we now say moon piglets?
Light-hearted tardigiggles aside, it’s hard not to feel sorry for the tiny sleeping creatures. In a dehydrated state, they can remain hibernating (I’m not sure if that’s the correct term for being freeze-dried, but let’s go with hibernating) for a decade (!) while they wait for water to appear so they can go about their tardigradey business. They’ve been discovered in just about every environment on Earth, are extremely resilient and can even survive in space without a tiny spacesuit to keep them warm. In short, they’re pretty amazing. And now they’re on the Moon, which may or may not be a good thing (there’s a lot of cosmic rays up there).
It’s been a looooong time since I last updated Astroengine.com, so first off, apologies for that. But today seems as good a time as any to crank up the ‘engine’s servers as the White House has rubber-stamped a manned NASA mission to an asteroid! However, this isn’t what the President originally had in mind in 2009 when he mandated the US space agency with the task of getting astronauts to an asteroid by the mid-2020’s.
In a twist, it turns out that NASA will be basing their manned asteroid jaunt on a 2011 Keck Institute study. To cut a long story short (you can read the long story in my Discovery News article on the topic: “NASA to Hunt Down and Capture an Asteroid“), NASA will launch an unmanned spacecraft to hunt down a small space rock specimen, “lasso” it (although “bagging” it would be more accurate) and drag the wild asteroid to park it at the Earth-moon Lagrangian point, L2. Then we can treat it like a fast food store; we can fly to and from, chipping off pieces of space rock, return samples to Earth and do, well, SCIENCE!
Overall, this robotic capture/manned exoplration of an asteroid saves cash and “optimizes” the science that can be done. It also lowers the risk associated with a long-duration mission into deep space. By snaring an asteroid in its natural habitat and dragging it back to the Earth-moon system, we avoid astronauts having to spend months in deep space. The EML2 point is only days away.
But when watching the exciting NASA video after the news broke today, I kept thinking…
But that wasn’t the only thing I was thinking. I was also thinking: what’s the point? It’s flashy and patriotic, but where’s the meat?
The human component of this asteroid mission has now been demoted to second fiddle. Sure, it will utilize NASA’s brand new Orion spacecraft and be one of the first launches of the Space Launch System (SLS), but what will it achieve? Astronauts will fly beyond Moon orbit, dock with the stationary space rock and retrieve samples as they please, but why bother with astronauts at all?
It is hoped that the robotic asteroid bagging spacecraft could launch by 2017 and, assuming a few years to steer the asteroid to EML2, a human mission would almost certainly be ready by the mid-2020s. But by that time, sufficiently advanced robotics would be available for unmanned sample retrieval. Heck, as telepresence technology matures, the EML2 point will be well within the scope for a live feed — light-time between Earth and the EML2 point will only be a few seconds, perhaps a little more if communications need to be relayed around the Moon. Robotics could be controlled live by a “virtual astronaut” on Earth — we probably have this capability right now.
The most exciting thing for me is the robotic component of asteroid capture. The advances in asteroid rendezvous and trajectory modification techniques will be cool, although scaling the asteroid bagging technique up (for large asteroids that could actually cause damage should they hit Earth) would be a challenge (to put it mildly). At a push, it may even be of use to a theoretical future asteroid mining industry. The rationale is that if we can understand the composition of a small asteroid, we can hope to learn more about its larger cousins.
The human element seems to be an afterthought and purely a political objective. There will undoubtedly be advancements in life support and docking technologies, but it will only be a mild taster for the far grander (original) NASA plan to send a team of astronauts into deep space to study an asteroid far away from the Earth-Moon system. The argument will be “an asteroid is a stepping stone to Mars” — sadly, by watering down the human element in an already questionable asteroid mission, it’s hard to see the next step for a long-duration spaceflight to Mars.
From this logic, we may as well just keep sending robots. But that wasn’t the point, was it?
Now, call your friends, grab a beer and celebrate the end of the Maya Long Count calendar’s 13th b’ak’tun and the winter solstice. (Sorry doomsayers, I will not be giving you a reference for your post-doomsday interview, you did a crappy job of the Apocalypse.)
Also, send your congratulations to my sister, Colette! IT’S HER 30TH BIRTHDAY! Congrats Sis!!
On a side note, a few of us appeared on the #TWISmageddon 21 hour marathon to talk about the end of the world (or lack thereof), science and the human propensity for believing the Mayan doomsday bunkum. Thanks to Kiki Sanford, Justin Jackson, Scott Lewis, Blair Bazdarich, Nicole Gugliucci and Andy Ihnatko for a terrific Google+ Hangout. Who knew doomsday would be so much fun! (We start at about 1hr 45mins into the Hangout.)
What the hell is going on with this weather balloon craze? It seems that everything from beer to sushi is being sent “into space” these days. There’s only one problem… weather balloons don’t go into space!
Just because you have a small camera with a gazillion megapixels, a credit card and a GPS tracker, the logic of buying a huge balloon and filling it with helium, strapping your camera to it and then running across the countryside to retrieve the wreckage seems silly. Sure, you get some nice video of cloud tops from an altitude of 20 miles, but you’re not the first to do this!
Having said all that, if you do feel compelled to create yet another YouTube video of a weather balloon launch, knock yourself out. But please, please, please don’t include the word “space” in the title, even the BBC gets confused (apparently, that weather balloon-launched Lego man went “into orbit”!). Space starts above 62 miles (known as the Kármán line). Weather balloons can make it to around 25 miles before popping. By no stretch of the imagination can balloons make it into “space.”
Also, weather balloons don’t take stuff on a “suborbital flight.” That’s about as “suborbital” as me taking a flight to Vegas.
Assuming Star Trek‘s Borg Collective went into overdrive and decided to build a huge cube a few thousand miles wide, then yes, the exoplanet-hunting Kepler space telescope should be able to spot it. But how could Kepler distinguish a cube from a nice spherical exoplanet?
The big assumption when looking for exoplanets that drift between distant stars and the Earth — events known as “transits” — is that the only shape these detectable exoplanets come in are spheres. Obvious really.
As a world passes in front of its parent star, a circular shadow will form. However, from Earth, we’d detect a slight dimming of the star’s “light curve” during the transit, allowing astronomers to deduce the exoplanet’s orbital period and size.
The transit method has been used to confirm the presence of hundreds of exoplanets so far, and Kepler has found over 1,200 additional exoplanet candidates. But say if astronomers paid closer attention to the shape of the received light curve; spherical objects have a distinct signature, but say if something looked different in the transiting “planet’s” light curve? Well, it could mean that something non-spherical has passed in front of a star. And what does that mean? Well, that would be a pretty convincing argument for the presence of a huge planet-sized artificial structure orbiting another star. Artifical structure = super-advanced alien civilization.
Arnold tested his theory that all manner of shapes could be detected by Kepler, assuming the transiting structure was on the scale of a few thousand miles wide. In this case, Arnold was testing his hypothesis to see whether we could detect an advanced civilization’s “shadow play.” Perhaps, rather than beaming messages by radio waves, an advanced civilization might want to signal their presence — SETI style — by blocking their sun’s light with vast sheets of lightweight material. As the shape passes in front of the star, the slight dimming of starlight would reveal an artificial presence in orbit.
By putting a series of these shapes into orbit, the aliens could create a kind of interstellar Morse code.
Of course, this is a rather “out there” idea, but I find it fascinating that Kepler could detect an alien artifact orbiting a star tens or hundreds of light-years away. Although this research is only considering orbital “billboards,” I quite like the idea that Kepler might also be able to detect a large structure like… I don’t know… a big Borg mothership. Having advanced warning of the presence of an aggressive alien race sitting on our cosmic doorstep — especially ones of the variety that like to assimilate — would be pretty handy.
NASA is giving Mars rover Spirit one more month to signal that she’s still alive before search operations are scaled back and attention shifted to her sister rover Opportunity. Unfortunately, the prognosis isn’t good. It’s been a little over a year since Spirit last communicated and it’s looking increasingly likely she’s succumbed to a lack of energy and freezing conditions on the Martian surface.
Donald Yeomans, head of NASA’s Near-Earth Asteroid Rendezvous mission, agrees with what I’ve been saying all along (especially since all that “Institute for Human Continuity” bullshit hit the internet). He said at the Pasadena Jet Propulsion Laboratory meeting:
“The film makers took advantage of public worries about the so-called end of the world as apparently predicted by the Mayans of Central America, whose calendar ends on December 21, 2012. [NASA] is getting so many questions from people terrified that the world is going to end in 2012 that we have had to put up a special website to challenge the myths. We have never had to do this before.”
Even though NASA agreed that Bruce Willis’ Armageddon was bad, it couldn’t compete with the scientific atrocities 2012 inflicted on its audience. The killer neutrinos, planetary alignment, crustal shift, geomagnetic reversal and super-duper-massive tsunamis proved too much. 2012 has even toppled The Core as worst sci-fi science movie. Now that is impressive.
But what does it all mean? Apart from us science snobs having a chuckle on our blogs, I doubt it will make the blind bit of difference. Why? This is why:
“On the opening weekend of 2012, the movie pulled in 65 million in U.S. ticket sales and an additional $160 million internationally, easily covering the $200+ million budget.
Movies aren’t about scientific accuracy, and it would seem that the hype behind 2012 can stand alone as the biggest moneymaker of all.
Fear sells, science doesn’t. The subject of doomsday will always be a blockbuster. Unfortunately, through the miscommunication of science, fear is usually the end-product.”
EDIT:An earlier version of this blog post stated that the Science and Entertainment Exchange was involved with NASA’s decision to make 2012 “most scientifically flawed” movie in its list. I have received an email from the Exchange’s director that this is not the case. I have therefore edited any mention of the Exchange from the blog (even though my source, the Adelaide Now, still references the Exchange).
So, it’s 2011. A brand new year. Who knows what it holds? Actually, I know what it holds. Trolls. In fact, 2011 will henceforth be the Year of the Troll. (Not the Year of the Rabbit, sorry Bun-bun.)
I’ve noticed a rather crazy uptick in the number of anti-science diatribes and wet doomsday theories in recent months. Most are due to questionable reports written on quasi-news websites (as debunked in “2012 Alien Invasion? Um, No.”), and others are down to the trolls who surf the web dropping comments under otherwise benign science articles. Could it be that Fakemageddon is a year away? Or has the use of computers been granted in kindergarten? Could be both.
Although I joke about the misguided individuals inventing tales of doom to sell books, there is a rather serious undercurrent to my 2012 ramblings. People genuinely worry about this stuff. Sure, I’m totally numb to all this 2012 tomfoolery — it’s all crap, honest — but I’m still receiving messages from readers who are convinced something bad is going to happen on Dec. 21, 2012.
(The only person I know who’ll have a bad time is my little sister, who’ll be turning 30 on that day — don’t worry sis, I’ll be there administering the vodka, it numbs the chronological pain, trust me.)
So where does that leave us? What can we do to divert the nonsense and bring some real science to the table?
For one thing, I’m going to keep writing about the crackpots perpetrating these silly myths through 2011 and beyond. Although fellow debunkers and myself have been under attack recently for even mentioning the 2012 thing — something about a dead horse and a good beating — it’s important to inject common sense into the Internet whenever nonsense appears. If these doomsday theories go unchecked, for some, science and pseudoscience may become confused.
This is where the “Truth Squad” (as MSNBC science editor and Cosmic Log space maestro Alan Boyle has dubbed us) comes in, and I’m pretty sure all space science bloggers will be on the lookout for the doomsayers’ tall stories.
How do we know this? Psychics — or “military grade remote viewers” as they like to be called — “saw” it, and their vision corroborated a Mars satellite photo that shows “man-made domes,” “pipelines” and a “huge nozzle shooting liquid spray.”
Before we get bogged down with the details, let’s get one thing straight: remote viewing is not a scientific tool and has never been proven to work. It is pseudoscience. Sure, the U.S. military became interested in investigating remote viewing as a spying weapon (unsurprisingly, the superpowers were pretty keen on investigating every avenue to spy on the enemy during the Cold War), but funding was withdrawn in the 90’s as it was proven remote sensing was ineffective and any positive results could not be replicated.
Most recently, the U.K.’s Ministry of Defence carried out a suite of experiments on a group of remote viewers to see how their brains reacted during the viewing phase. There appeared to be no measurable change in brain activity, and besides, none of the psychics tested could access the desired targets anyway, rendering the whole thing pointless.
But these facts don’t seem to dissuade Dr. Courtney Brown from trying to justify a scientific basis for his “Evidence for Artificiality on Mars” presentation. Not surprisingly, one of the Examiner’s “Exopolitics” writers is very exited about this non-research, saying, “An apparent active industrial site on the surface of Mars with a “large nozzle shooting a liquid spray” onto an apparent industrial waste area has been successfully located and explored in a remote viewing study conducted by the Farsight Institute in March 2010 using nine highly trained remote viewers and methodologies developed by the U.S. military.”
Here’s the region of Mars we’re talking about, helpfully labeled to show the targets for the remote viewers. These targets are obviously highly suspicious, they look nothing like the rest of the Aram Chaos region of Mars (*squints*):
Take a look at the original Mars Global Surveyor images of the site. It might take a couple of minutes to find the area of interest, which isn’t surprising as it looks like the rest of Mars.
Now the remote viewers have their targets, the Farsight Institute carried out some kind of experiment and Dr. Brown — a guy with a book to sell (where have we seen that before?) — discusses the astonishing results. In case you think I’ve eaten a funny-looking mushroom or been lobotomized by a trained hamster, this “evidence” for remote viewing is listed on the Farsight Institute’s webpages. I’m not making this up.
In the Mars orbiter photo (above), a spraying fountain of some “liquid” (target 1a) can be seen. In fact, this is the whole reason why Brown has taken an interest in this region. “We wouldn’t be interested in these domes if it wasn’t for the spray,” he said, “but the spray really caught our attention.” This spray is being ejected by a mountain-shaped dome (target 1b) via a horizontal “pipe.” There is a shadow under the spray indicating it is being ejected at some height. There is also another “highly reflective” dome below the other dome (target 1c). “It looks like it’s made out of some kind of resin material,” Brown remarks.
So, using their psychic powers, the military-grade remote viewers managed to access some fascinating details about the site — they even drew some vague scribbles of their visions.
The artificial structures on Mars were originally built by ancient builders and the current occupants do not understand its technology. They need spare parts, but don’t have any. The mystery technology in operation generates power and there are intense flashing lights at the site. The occupants on site — of which there are more men than women — are despondent (because there are more men than women? Because no one knows they’re there? There’s no good coffee in the canteen? Just guessing). The occupants, assumed to be human, are in a lot of hardship and they aren’t allowed to return home.
Apart from sounding like a sweat house scene ripped straight from an 18th Century Jane Austin novel, the very idea the U.S. military has some kind of black operation on the Red Planet is hilarious. But to single out one tiny region of the planet by pure chance (because Brown thinks he sees a pipe gushing water over the landscape) and creating a fantasy world using zero logical thought is amazing to me.
The “gushing fluid” feature could be any one of a huge number of geological features. To me, it looks like a landslide; lighter material that has been dislodged, causing rubble to tumble down the slope. It could even be ice mixed in with regolith after an avalanche, ice crystals falling from the top of the mesa (a hill; not what Brown describes as anything man-made) scattering over the darker colored material further down the slope.
The shadow Brown points to is not caused by this “spraying liquid” feature, it’s simply darker-colored material in the Martian soil. There goes that theory. As for the other suggestions of man-made structures… well, that’s just Brown’s vivid imagination. I’m finding it hard to see any man-made domes. They’re just hills.
This crazy theory could be picked at for hours, but I’m still in amazement that people like Brown can discuss a subject like this with such conviction. There is overwhelming evidence that easily debunks the idea that there is an industrial complex on Aram Chaos. Unfortunately, for people peddling their pseudo-scientific ideas, common sense and logical thought seem to be concepts they have trouble grasping.
