Maybe E.T. Hasn’t Come Calling Because Human Messages Are “Messy”

In the noble pursuit of contacting aliens, we humans have broadcast images, music, voices, and more into space, but have you ever stopped to think that maybe we’re sending mixed messages? Some astronomers have, and to counter that problem they’ve suggested creating standard rules for all future space-bound missives–and they want to harness the power of crowdsourcing to “edit” these messages.

In their Space Policy paper, a team of alien-hunting scientists say that standard message protocols would increase the likelihood that aliens would hear us, one goal for those involved with SETI, or the search for extraterrestrial intelligence. Wired Science quotes astrobiologist Jacob Haqq-Misra:

“The paper is really a call for unity among thinking about messaging exraterrestrials,” Haqq-Misra said. “Right now it’s messy, it’s kind of all over the place. Maybe we can increase our success chances by being more unified about this.”

Android… in… Space! A Smartphone Prepares for Blast-Off

Cell phones will soon make a giant leap for mankind–right into outer space. In the coming year, British engineers from Surrey Satellite Technology Limited (SSTL) plan to send a cell phone into orbit to test whether cell phones are tough enough to withstand outer space, and whether they’re powerful enough to control satellites. As the BBC reports:

“Modern smartphones are pretty amazing,” said SSTL project manager Shaun Kenyon…. “They come now with processors that can go up to 1GHz, and they have loads of flash memory…. We’re not taking it apart; we’re not gutting it; we’re not taking out the printed circuit boards and re-soldering them into our satellite – we’re flying it as is,” Mr Kenyon explained.

The jury’s still out as to what cell phone model will be the world’s first orbital smartphone–but the scientists have already decided to pick one that uses Google’s Android operating system. That software is open source, allowing the engineers to tweak the phone’s functions. Not every phone, after all, comes off the shelf with the ability to navigate a nearly 12-inch-long, GPS-equipped, pulsed-plasma thruster satellite.

NASA Found Aliens! Or Not. The Worst Coverage of Arsenic-Loving Bacteria

not-an-alienWhile watching the science news for you here at Discover blogs, we’ve seen our share of bad science coverage. Most of the time, we let it slide. Most of the time, we write the truth and hope to overshadow the erroneous and exaggerated stories. But this time… this time we’re calling it out.

Last week’s coverage of the bacteria that live in Mono Lake, CA was over hyped because of a cryptic message in a NASA press release (namely, that the discovery would “impact the search for evidence of extraterrestrial life”). And even after all the build up, the early embargo break, and a long press conference, many news outlets STILL got the story wrong.

NASA and Etsy Team Up to Get Their Space Craft(ing) On

<p>NASA threw down the <a href="http://www.etsy.com/nasa/index.php" target="_blank">space-crafting gauntlet</a> for<a href="http://www.etsy.com/nasa/index.php" target="_blank"> Etsy</a> crafters a few weeks ago, challenging them to create and submit their own NASA-inspired art:</p>
<p style="padding-left: 30px;">Entrants share an original handmade item or work of art inspired by NASA and NASA's programs, such as the Space Shuttle Program and human spaceflight, aeronautics, science and exploration of the universe.</p>
<p>The challenge is part of NASA's effort to reach out to the female members of the younger generation; Etsy's user base is 96 percent women, and most are under 35. The contest's grand prize winner will get a $500 shopping spree on Etsy, and a trip to attend the launch of the space shuttle <em>Endeavor</em> in February 2011.</p>
<p>The submissions thus far include paintings, sculptures, jewelry, clothing, and much more, so we went ahead and picked out some of our favorites and asked what inspired their artists. Take a gander at the <a href="http://www.etsy.com/nasa/entries.php" target="_blank">whole lot of submissions</a> if you have a minute.</p>
<p>This little <a href="http://www.etsy.com/listing/58987809/retro-the-rocket-aka-october-sky" target="_blank">pocket rocket</a> was made by Etsy crafter <a href="http://www.etsy.com/shop/trinlayk?ref=seller_info" target="_blank">trinlayk</a>, who specializes in amigurumi (aka crocheted stuffed animals) that she sells on Etsy and at science fiction conventions.  She says her creation was inspired by a lifetime fascination with science fiction and space:</p>
<p style="padding-left: 30px;">I remember the early space shots that led up to landing on the moon, as well as remembering sitting in the family in front of our big TV in the Den (past my bedtime? up early?) to see them as well as the later moon landing.</p><p>Vanessa Hotchkiss, who goes by user name <a href="http://www.etsy.com/shop/bailybellecreations" target="_blank">Bailybellecreations</a> on Etsy created a <a href="http://www.etsy.com/listing/54166436/jupiter-orange-onyx-and-sterling-silver" target="_blank">Jupiter-inspired necklace</a> for the contest. Her work is inspired by her love of astronomy, and a burning desire to visit NASA:</p>
<p style="padding-left: 30px;">Wouldn't it be fabulous if I could start all over and become and astronaut! Since that's not possible I would love to visit NASA at least once in my life!</p>
<p>She specializes in jewelery of every kind, so check out the rest of her shop for the <a href="http://www.etsy.com/listing/58705924/on-sale-jupiter-orange-onyx-and-sterling?ga_search_query=Jupiter&amp;ga_search_type=user_shop_ttt_id_5508264" target="_blank">matching earrings</a> and other good stuff.</p><p>These planets may appear smaller than they are--the <a href="http://www.etsy.com/listing/58806554/planetswheelthrown-stoneware-textured" target="_blank">planetary sculptures</a> are about 8.5 inches across. They were created by artist Marietta Theodorou-LeMieux, who goes by <a href="http://www.etsy.com/shop/blueroompottery" target="_blank">blueroompottery</a> on Etsy, as a part of her "Pleiades" series, inspired by the shuttle program and the constellation Pleiades.</p>
<p>The porcelain spheres are purely decorative, and are made from recycled clay and glazed to get a rustic, lava-like texture.</p><p>This handmade sculpture was created by Sheila Loggan, who goes by <a href="http://www.etsy.com/shop/sheilasthings" target="_blank">sheliasthings</a> on Etsy. She was inspired by her grandson's lifelong love of space and her childhood ideas about what a spacecraft would look like:</p>
<p style="padding-left: 30px;">My grandson is nearly 13 years old and since he was a little child he has been interested in NASA and space travel. He is working hard toward a chance to attend college in Texas so that he has a better chance to be noticed by NASA. So my interest in NASA stems from my love for my grandson I suppose!</p><p>Paul Klassett and Kate Archie team up to make <a href="http://www.etsy.com/shop/paulandkatestudio" target="_blank">paulandkatestudio</a>, where they specialize in ceramic bowls and sculptures. One series of planet sculptures was inspired by an asteroid project they created for a friend, and each planetoid is handmade and one-of-a-kind. Their shared interest in astronomy has been life-long:</p>
<p style="padding-left: 30px;">Paul and I have always been interested in astronomy &amp; outer space and are avid sky watchers. One of Paul’s favorite books is the classic <em>The Cosmic Connection</em> by Carl Sagan, and while less cerebral but just as inspirational, my favorite movie ever is <em>Alien</em>.</p>
<p>Their creation for the contest is this <a href="http://www.etsy.com/listing/34996001/prehistoric-planet" target="_blank">little brown planet</a>, which is covered in pockmarks and volcanoes from its turbulent teen years.</p><p>This "<a href="http://www.etsy.com/listing/58673354/sale-two-finger-ring-triple-moonball" target="_blank">two finger moon ring</a>," created by Erica Schwartz, who goes by <a href="http://www.etsy.com/shop/designerica?ref=seller_info" target="_blank">designererica</a> on Etsy, is intended to be a little reminder of the incredible vastness of space and the possibilities that are out there.</p>
<p style="padding-left: 30px;">I guess part of my fascination with science fiction and space is related to the idea that space is "the final frontier," but it goes beyond that. To me, space and space exploration represent the vast possibilities that the future offers. It is thrilling to dream of what may be out there, to invent possibilities, and to learn about the actualities.</p><p>Using pages from water damaged books and bright colors Kelly Cook, who goes by <a href="http://www.etsy.com/shop/Cookstah?ref=seller_info" target="_blank">cookstah </a>on the site, created this <a href="http://www.etsy.com/listing/58573306/hang-the-moon-original-mini-painting-on" target="_blank">mini-moon painting</a> for the contest. Her interest in space (originally spurred by the movie <em><a href="http://en.wikipedia.org/wiki/SpaceCamp" target="_blank">Space Camp</a></em>) was reignited by her two sons' interest in space. She says she has a special place in her heart for the moon:</p>
<p style="padding-left: 30px;">I used the ideas of fall, the harvest moon, cooler temperatures and the distant and familiar feeling that earth's moon gives me. I LOVE space, I am almost intimated to think about the endlessness of the universe. The moon makes me feel like that this huge place is local, approachable.</p>

Don’t Give Up Hope: Earth Has Not Yet Selected an Alien Ambassador

alienThe truth is out there… but it’s not that Mazlan Othman is going to be our space ambassador, as recently reported by The Sunday Times (paywall) and reprinted in The Australian:

The United Nations, tackling head-on the problem of what to do if an alien says “take me to your leader”, is poised to designate a specific individual for the task…. An obscure Malaysian astrophysicist who is head of its little-known Office for Outer Space Affairs (Unoosa).

The story, which was widely reported over the weekend, was published on Sunday at 12:50 pm AEST (Saturday, 9:50 pm EDT). It compared Unoosa and Othman to the Men In Black and even quoted experts in space policy:

Professor Richard Crowther, an expert in space law and governance at the UK Space Agency and who leads British delegations to the UN on such matters, said: “Othman is absolutely the nearest thing we have to a ‘take me to your leader’ person.”

The story was then picked up by The Telegraph, which published on Sunday at 11:30 am BST (Sunday, 6am EDT), discussing the details of Othman’s push for her new role:

She will set out the details of her proposed new role at a Royal Society conference in Buckinghamshire next week. The 58-year-old is expected to tell delegates that the proposal has been prompted by the recent discovery of hundreds of planets orbiting other starts, which is thought to make the discovery of extraterrestrial life more probable than ever before.

From there the story spread to various other news sites, including CNET, Daily Mail, Wired.co.uk, and Time before anyone thought to actually check the facts of the Australian article. At around 8 am EDT on Monday The Guardian posted a story claiming that that Mazlan Othman has officially denied the statement:

Finally an email from Othman herself would have prompted our Martian to trudge back to his spaceship. “It sounds really cool but I have to deny it,” she said of the story. She will be attending a conference next week, but she’ll be talking about how the world deals with “near-Earth objects”. Our alien will just have to try someone else, or stop reading the Sunday Times.

Undergrads Destroy NASA Satellite

LASP_satellite-controlOn August 30th, after seven years gathering data on ice sheets and sea ice dynamics, a NASA satellite met its fiery end in the Earth’s atmosphere before plunging into the sea. And it was University of Colorado at Boulder undergraduates who plotted the satellite’s fatal course.

Happily this wasn’t the result of a Hacking 101 class gone awry, or a particularly sophisticated prank. The students’ destructive mission had NASA’s full endorsement.

NASA decommissioned the Ice, Cloud and Land Elevation Satellite, or ICESat in July, before turning the show over to the students, who worked with experts from the university’s Laboratory for Atmospheric and Space Physics.

Man Claims That Aliens Are Pelting His House With Meteorites

meteoriteMaybe, for a man in northern Bosnia, the sixth time is the charm: Radivoke Lajic claims that six meteorites have now struck his home.

The chances of being struck by a meteorite are extremely small, but, according to Lajic, his home has served as meteorite target practice since 2007. According to The Telegraph, where we found this story, Lajic says that the rocks tend to come when it rains. Ok, sure–and maybe Paul the psychic octopus can predict when the next one will come hurtling down.

A Wired article from last year cites a 1991 study by The Royal Astronomical Society of Canada of worldwide meteorite strikes near humans and built structures. The study records only a total of 57 strikes on human infrastructure in the 20th century.

Never mind facts and statistics, though! Lajic has set up a meteorite museum in his backyard. The Telegraph also reports that he has paid for a steel girder for his home by selling the first of the meteorites and has now launched an investigation into the magnetic fields around his home. Maybe it would have been better to take the cash from the first rock and move?

Lajic’s explanation for his home’s apparent meteorite attraction is that aliens are out to get him. He told The Telegraph:

“I have no doubt I am being targeted by aliens…. They are playing games with me.”

Buzz Aldrin Explains: How to Take a Whiz on the Moon

144832main_aldrin_bootprintCharged with writing to an astronaut, a five-year-old boy asked a burning question: How do you pee and poop in your astronaut suit?

In an interview with Buzz Aldrin just published in Vanity Fair, contributing reporter Eric Spitznagel finally got this answer:

“We were well skilled in the art of disposal waste. There was such a thing called a ‘blue bag,’ which was kind of messy. There was a stickum on it, and you could stick it around your posterior. For urinating we had an ego-buster, which was like a condom catheter. We were cautioned not to overestimate our size. (Laughs.) Because if the condom was too big, there might be a little leakage.”

The story continues: Aldrin describes in full detail what happens if you *do* have a little “leakage” (wiggle it out into a larger bag) and where astronauts flush those blue baggies. Aldrin tells Spitznagel about a newbie mistake of tossing the bags (during extra-vehicular activity) in a trajectory that brought them straight back at their capsule.

“We looked out the window and there were three bags in a row, heading straight for us.”

In case, Spitznagel isn’t the only one wondering about space crap, you should know that taking care of business has come a long way since blue bags. Astronauts potty train using simulators before their travels. The Space Shuttles and International Space Station both have air-flushing toilets, and the International Space Station recycles pee.

World Science Festival: The 4 Ways to Find E.T.

P1010483How do you hunt for extraterrestrial life? You visit other planets, you find new planets, you study our own planet, or you listen.

All four methods came together last night at the World Science Festival when four speakers took part in a conversation called, simply, “The Search for Life in the Universe.” When you put four lively scientists with four different ways of thinking on a stage together, consensus isn’t the first thing to emerge. But the panel could agree on one thing: If you yearn to know whether we’re alone in the universe, it’s a hell of a time to be alive.

1. Mars

Steve Squyres of Cornell University is one of the project leads on the Mars rovers, those endurance robots Spirit and Opportunity that continue sending back Martian data. Spirit may be stuck, but in this week’s edition of the journal Science, Squyres’ team has published a new study based on information the rover found at a rock outcropping called Comanche about four years ago.

Spirit found evidence of carbonates that would have formed in the presence of water. The rover had done that before, but what’s exciting now, Squyres says, is that the chemistry of these new carbonate finds show they formed in water of a more neutral pH, rather than the more acidic circumstances that would have formed prior carbonate finds.

That water no longer flows on the martian surface, but “this points to more life-friendly conditions” billions of years ago, he said.

2. A Second Earth?

Humans have long imagined faraway planets around other stars, Harvard astronomer David Charbonneau said. “We are all alive at this magical moment when we have the technical ability to find those planets.”

The count of known exoplanets now stands at greater than 400, and astronomers have found most of those by one of two methods. There’s the wobble, in which astronomers spy a star jostled ever so slightly by its planet’s gravity. It’s like watching a dance, Charbonneau said, “it’s just that one of the dance partners is 1,000 times heavier than the other.” Secondly, there’s the transit method, in which a planet passes in front of its star and dims the star slightly, giving away its presence.

Charbonneau is also a member of the Kepler Space Telescope team. It launched last year with the express purpose of exoplanet hunting, and at the World Science Festival he predicted it would find a truly Earth-like world in two to three more years (he’s gotten close already). Plus, in 2014, exoplanet hunters will get another assist from this bad boy, the James Webb Space Telescope, a full-scale replica of which is currently on display in Battery Park.

P1010466

3. Science Staycation

“This is my favorite planet, I have to say.”

Michael J. Russell is the most Earth-focused of the four panelists who spoke last night. And he might be the most convinced that Earth is not alone in harboring life. As someone who studies the emergence of life on our homeworld, especially the possibility that it emerged in the pressure cooker of deep-sea vents, Russell is impressed by the reach and expansion of life here. And that’s a good sign for life elsewhere in the universe.

What can Earth tell us about life on distant worlds? Life, Russell says, leaves evidence of itself in the waste it leaves behind. It accelerates chemical reactions—through photosynthesis, for example. Says Russell: “The question isn’t, ‘What is life?’ What we should ask is, ‘What does life do?’”

4. SETI

Zeta rays. Zeta rays are the key.

OK, I don’t know what zeta rays are, and neither does Jill Tarter, longtime member of the Search for Extraterrestrial Intelligence (SETI). The point is that we’re using technologies and weird physics that we didn’t know about a half-century ago when SETI was founded. Given our location in the galaxy, she says, any civilization that might like to contact us probably has had more time to mature. “We can be fairly confident that we are the youngest,” she said.

Thus, we use the methods we know—like optical and radio signals—to search for alien intelligences. But they might be trying to reach us with zeta rays, or some other crazy thing we haven’t discovered yet. That, plus the great vastness of the galaxy, tells Tarter that 50 years of nothing but silence doesn’t mean SETI is a failure. It means they’re just getting started.

[Read more about SETI's first 50 years in the feature "Call Waiting" in the July/August issue of DISCOVER, on newsstands soon.]

So what if it’s out there?

“First of all, I’m going to take a drink of champagne,” Tarter said.

In case you were worried, SETI does have a plan in place for its response to an alien signal. Tarter says the scientists won’t attempt to respond themselves, but would rather tell the world and try to reach a global consensus for our planet’s next move.

Right… “global consensus.” Tarter concedes that this sounds great on paper and is probably impossible to achieve. But in a socially connected world, maybe we can just take a vote on whether or not we want to tell E.T. we’re here.

That plan, of course, would apply only if we found intelligent life. But if we detected even “pond scum,” Squyers said, the achievement would be monumental. He’s willing to accept that habitable environments proliferate throughout the galaxy. Even in our own solar system, promising locales for life like the moons Europa and Titan lie outside what we would call the “Goldilocks Zone.” But finding that life independently arose twice just in our own tiny solar system would mean to him that the universe is “teeming with life.”

I hope it is.

Sounds of the Universe: Making Music From the Supernova Cassiopeia A

cassWhile we know what it looks like when a star explodes into a luminous supernova, here’s a chance to discover what one sounds like–sorta. Scientists have translates a supernova’s electromagnetic waves into waves of sound; and when there is sound, there is music. Enter the Grateful Dead.

The band’s famed percussionist Mickey Hart is working on a musical project to “sonify” the universe–taking sounds collected by scientists from supernovae and other astronomical phenomena and using them in his new album “Rhythms of the Universe.” To anyone who has ever heard one of the Grateful Dead’s extended “drums and space” jams, this shouldn’t come as much of a surprise.
