"'There is 'something new and interesting going on in the universe,' said Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md." Aspiring Jor-Els: Best get to work on those interstellar child-bearing rockets. Scientists detect a distant -- and very loud -- roar on the other side of the universe. "'The universe really threw us a curve,' Kogut said. 'Instead of the faint signal we hoped to find, here was this booming noise six times louder than anyone had predicted.'" (Sssh, listen...there went Earth-2.)

"'An automated rendezvous does all sorts of things for your missile accuracy and anti-satellite programs,' said John Sheldon, a visiting professor of advanced air and space studies at Maxwell Air Force Base in Alabama. 'The manned effort is about prestige, but it’s also a good way of testing technologies that have defense applications.'" In order to keep pace with the increasingly proficient Chinese space program, President-elect Obama may be considering retying NASA to the Pentagon, "because military rockets may be cheaper and ready sooner than the space agency’s planned launch vehicle, which isn’t slated to fly until 2015...Obama has said the Pentagon’s space program -- which spent about $22 billion in fiscal year 2008, almost a third more than NASA’s budget -- could be tapped to speed the civilian agency toward its goals as the recession pressures federal spending."

Hmm. On one hand, I would think making NASA yet another fiefdom of the Pentagon would greatly facilitate its ability to lock down the funding it needs for various exploratory endeavors, recession or no. And if the types of conveyance vehicles NASA needs are basically sitting around gathering dust in some Pentagon-owned warehouse next to the ark of the covenant, well then it only makes sense to combine the two programs. No need to reinvent the, uh, rocket.

On the other hand, putting the brass in charge is probably going to have deleterious effects on the types of projects NASA pursues in the future. And, in a perfect world, there's something to be said for having a civilian space program completely outside the purview of the military. In fact, now that i think about it, won't combining the Pentagon and NASA space programs cut back on the types of international cooperation that have guided our efforts in space in recent years? GIven the current economic climate, I guess this is the best way for NASA to continue pursuing its goals in the short term. Still, there could well be trouble ahead.

"Lemmings do not engage in suicidal dives off cliffs when migrating. They will, however, occasionally, and unintentionally fall off cliffs when venturing into unknown territory...The misconception is due largely to the Disney film White Wilderness, which shot many of the migration scenes (also staged by using multiple shots of different groups of lemmings) on a large, snow-covered turntable in a studio. Photographers later pushed the lemmings off a cliff."

LMG points the way to an interesting list of common misconceptions over at Wikipedia. "The Inuit do not have a large number of words for snow. One Eskimo-Aleut language studied had four unrelated root words...By comparison, English has many unrelated root words for snow as well: snow, sleet, powder, flurry, drift, avalanche and blizzard."

"'We've discovered this incredible dark energy, we don't understand what the hell it is,' said Lawrence Krauss, a physicist at Arizona State University. 'It's extremely small, extremely weak, and it's so close to being zero, it's just a total mystery why it should have this small value and not be zero." While they're still not entirely sure what in fact they're looking at, Harvard-Smithsonian astrophysicists announce they've found another way to measure and quantify "dark energy", a.k.a. the repulsive "cosmological constant" force causing the universe to expand rather than contract. "This is a much-needed confirmation that the earlier work was correct, the astronomers said, comparing it to football referees examining a controversial play with multiple camera angles."

As an added bonus, the results announced today also seem to confirm Einstein's general theory of relativity. "'It's never been proved right on the scale of the observable universe,' Spergel said."

"Although we think of black holes as somehow threatening, in the sense that if you get too close to one you are in trouble, they may have had a role in helping galaxies to form -- not just our own, but all galaxies." German astronomers believe they have discovered a black hole right in the center of our Milky Way. "According to Dr Robert Massey, of the Royal Astronomical Society (RAS), the results suggest that galaxies form around giant black holes in the way that a pearl forms around grit."

And, if that wasn't heady enough news to wrap one's mind around, see also this article on loop quantum cosmology (LQC) and "The Big Bounce." "LQC has been tantalising physicists since 2003 with the idea that our universe could conceivably have emerged from the collapse of a previous universe. Now the theory is poised to make predictions we can actually test. If they are verified, the big bang will give way to a big bounce and we will finally know the quantum structure of space-time. Instead of a universe that emerged from a point of infinite density, we will have one that recycles, possibly through an eternal series of expansions and contractions, with no beginning and no end." (Both links via Dangerous Meta.)

"Said John Logsdon, a George Washington University professor who co-wrote the book honored at the NASA party, 'There is a natural tension built into this situation... Mike is dead-on convinced that the current approach to the program is the right one. And Lori’s job is to question that for Mr. Obama. The Obama team is not going to walk in and take Mike’s word for it.'" The Orlando Sentinel suggests that NASA head Michael Griffin isn't being particularly helpful to the transition team at the agency: "NASA administrator Mike Griffin is not cooperating with President-elect Barack Obama’s transition team, is obstructing its efforts to get information and has told its leader that she is 'not qualified' to judge his rocket program, the Orlando Sentinel has learned."

I've been quite complimentary of Mike Griffin here in the past. He seems like a smart, take-no-guff fellow, and I'm in general agreement with his views on space exploration. But this sort of tantrum reflects poorly on him. Knowing nothing other than what's written in this article, it sounds like Griffin, a holder of six advanced degrees, is indulging his engineer's exasperation with the laypersons who seem to be meddling with his current experiment. But if Griffin wants to see the vision he's outlined for NASA make it into the next administration, I suspect honey would garner more flies than vinegar at this moment.

"The last Twitter post said it all: "01010100 01110010 01101001 01110101 01101101 01110000 01101000."" Or, in other words, Ground Control to Phoenix Lander: You've really made the grade. Having seemingly succumbed to the Martian winter at last, the Mars Phoenix Lander is pronounced deceased by NASA. "NASA official Doug McCuistion counseled people to view Phoenix’s end as 'an Irish wake rather than a funeral. It’s certainly been a grand adventure.'...While some followers said farewell to Phoenix in computer language today, others kept it simple. 'Good bye Phoenix, I love you :(,' said user patach."

Europa, Enceladus...Titan? The ESA's Cassini-Huygens probe discovers a liquid lake on Saturn's largest moon, although it's definitely not water. ""Detection of liquid ethane in Ontario Lacus confirms a long-held idea that lakes and seas filled with methane and ethane exist on Titan." [Via Quiddity.]

"'It was very emotional for me,' he said. 'I thought, "Oh my God, we're getting closer."'" I'll say...Richard Branson and Burt Rutan unveil their space tourism mothership, the White Knight Two. "Virgin Galactic envisions a future where space voyages will become as common as airplane travel. It wants to fly 500 people into space in the first year for $200,000 a head...So far, more than 250 wannabe astronauts have paid the full amount." Hmm...maybe it's time to start putting ads on this site.

ESA's Mars Express sends back some impressive postcards from Mars. "Over the last five years its stereo, high resolution camera has taken thousands of images of the surface, revealing the planet's awe inspiring beauty in unprecedented detail."

"'There's nothing about it that would preclude life. In fact, it seems very friendly,' said mission scientist Samuel P. Kounaves of Tufts University. 'We were flabbergasted.'" Hope y'all like asparagus: Early tests by the Mars Phoenix seem to indicate that the Martian soil is more nutrient-rich than anyone expected. "Carbon-based organic material, however, has not been found and may be impossible to detect with the equipment now on Mars."

"It's with great pride and a lot of joy I announce today we have found proof that this hard material really is water ice and not some other substance." Signs have pointed in that direction for awhile now, and particularly since the Phoenix landed. But now, it seems we have really, truly, definitively found ice on Mars. "The next questions to answer are what chemicals, minerals and organic compounds might be mixed in with the water. 'Just the fact that there's ice there doesn't tell you if it's habitable,' Smith said. 'With ice and no food it's not a habitable zone. We don't eat rocks — we have to have carbon chain materials that we ingest into our bodies to create new cells and give us energy. That's what we eat and that's what has to be there if you're going to have a habitable zone on Mars.'"

"'They're taking an Apollo-like approach,' Gilbreth said. 'Our program is much more ambitious than Apollo. We're going to put four people on the moon for seven days, eventually for six months. China is looking for a minimum capability. We're looking to put an outpost on the moon.'" NASA officials concede that China will beat the US back to the moon. "The goal of NASA's Constellation program is to return astronauts to the moon by 2020...Gilbreth said the Chinese could accomplish that by 2017 or 2018."

Moreover, that US date will likely slip five years when Pres. Obama takes office in January. In all honesty, this is one of the few areas where I emphatically disagree with our nominee. There are plenty of places to acquire $18 billion for education without raiding the space exploration budget...defense bloat, for example.

"'We were expecting to find ice within two to six inches of the surface,' said Phoenix principal investigator Peter Smith of the University of Arizona in a statement. 'The thrusters have excavated two to six inches and, sure enough, we see something that looks like ice. It's not impossible that it's something else, but our leading interpretation is ice.'" Well, it sure looks like ice. The Phoenix Mars Lander seems to have found its quarry almost immediately after landing. And where there's water...

"In my dreams it couldn't go as perfectly as it went tonight, we went right down the middle." Touchdown: NASA's Phoenix Mars Lander, soon to look for water in the Martian Arctic, lands without incident in the Vastitas Borealis plains. Congrats!

"It's very deep, like in a forest on the darkest night,' said Shawn-Yu Lin, a scientist who helped create the material at Rensselaer Polytechnic Institute in Troy, N.Y. 'Nothing comes back to you. It's very, very, very dark.'" Dick Cheney's soul? Tonight's lunar eclipse? No, a great leap forward in "transformational optics"...and invisibility cloaks. The "paper-thin material...absorbs 99.955 percent of the light that hits it, making it by far the darkest substance ever made -- about 30 times as dark as the government's current standard for blackest black."

"'This is a landmark discovery because it implies that solar system analogs may be very common, at least scaled-down versions,' said Sara Seager, an extra-solar planet expert from the Massachusetts Institute of Technology. '...We are on an inexorable path to finding other Earths.'" Astronomers find a solar system not unlike our own 5,000 light years away. "We are seeing the emergence of a new planet-finding technique -- one that opens up an entirely new capability for planet finding. It is more powerful than we ever thought possible."

"It could be the weirdest and most embarrassing prediction in the history of cosmology, if not science. If true, it would mean that you yourself reading this article are more likely to be some momentary fluctuation in a field of matter and energy out in space than a person with a real past born through billions of years of evolution in an orderly star-spangled cosmos. Your memories and the world you think you see around you are illusions."

In today's NYT, Dennis Overbye attempts to explain the Boltzmann Brain problem, a theoretical puzzle causing consternation among cosmologists. “'It is part of a much bigger set of questions about how to think about probabilities in an infinite universe in which everything that can occur, does occur, infinitely many times,' said Leonard Susskind of Stanford, a co-author of a paper in 2002 that helped set off the debate. Or as Andrei Linde, another Stanford theorist given to colorful language, loosely characterized the possibility of a replica of your own brain forming out in space sometime, 'How do you compute the probability to be reincarnated to the probability of being born?'”

Um, yeah. The graphic sorta helps explain what may be going on: Minute fluctuations in the universe's general move towards entropy create random pockets of order, some of which could hypothetically organize as floating brains, or pocket universes or whales and flowerpots too, I suppose. Or something like that...Now my brain hurts.

"And from the crew of Apollo 8, we close with good night, good luck, a Merry Christmas, and God bless all of you -- all of you on the good Earth." Happy holidays to everyone out there. Berk and I are currently at the family homestead, where I'm enjoying home cooking, catching up on work and -- true to form -- checking out some of the better video games of the year: Call of Duty 4, Portal, Rock Band (I'm the frontman.) Hope your own holidays are equally fun and relaxing.

"...as if millions of voices suddenly cried out in terror and were suddenly silenced." Scientists at NASA catch a glimpse of cosmic devastation on a galactic scale, as a "death star galaxy," fueled by a black hole, destroys its neighbor with a beam of radiation. "The telescope images show the bully galaxy shooting a stream of deadly radiation particles into the lower section of the other galaxy, which is about one-tenth its size...Tens of millions of stars, including those with orbiting planets, are likely in the path of the deadly jet...If Earth were in the way -- and it's not -- the high-energy particles and radiation of the jet would in a matter of months strip away the planet's protective ozone layer and compress the protective magnetosphere." And what does that mean? "'You would basically render extinct all surface forms of life,' Tyson said. 'But it may be that subterranean life is...immune to this kind of violence in the universe.'" You heard the man...start digging.

"Human beings evolved in gravity, and it makes perfect sense that some systems -- especially the immune and skeletal systems -- might not do well without it." A new NASA study finds microbes and viruses may be particularly lethal on long space flights. "Even though astronauts are not now getting sick on their missions, we see very clearly statistically significant and reproducible change in immune functioning after two weeks in space."

Have we inadvertently killed Schrödinger's cat? No, it's much, much worse. Cosmologists at Case Western Reserve and Vanderbilt speculate that mankind may have hastened the end of the universe by observing dark energy in 1998. "[Q]uantum theory says that whenever we observe or measure something, we could stop it decaying due what is what is called the 'quantum Zeno effect,' which suggests that if an 'observer' makes repeated, quick observations of a microscopic object undergoing change, the object can stop changing - just as a watched kettle never boils...Prof Krauss says that the measurement of the light from supernovae in 1998, which provided evidence of dark energy, may have reset the decay of the void to zero -- back to a point when the likelihood of its surviving was falling rapidly. 'In short, we may have snatched away the possibility of long-term survival for our universe and made it more likely it will decay,' says Prof Krauss." D'oh! But wouldn't this presume that at no other place or time in our unfathomably gigantic universe did any other civilization make the same observations? Given the odds of intelligent life out there, that seems unlikely. (And, if you think this all sounds goofy and ridiculous, just wait until we get to the multiverse...)

"Fact:...The density of Saturn is so low that if you were to put it in a giant glass of water it would float." And another pilfered link, which I meant to post last week: Megg of Quiddity points the way to 10 Cool Facts about Space (although, to paraphrase The Smiths, some facts are cooler than others.)

"If the current proposals to restart human exploration fail politically, indeed, the human space flight endeavor conducted under government auspices might well lose its momentum. I obviously hope that doesn’t happen. But it’s far from a slam dunk that we’re going back to the Moon and on to Mars." Two companion pieces to today's reflection on 50 years of Sputnik which I missed earlier: The Grey Lady hypothesizes about the next fifty years of space travel (suggesting its future as a public enterprise might be dubious) and takes a moment to consider the pop culture ramifications of the space age. "'At the level of government, I think we’re still struggling as to why we’re sending people to space,' Dr. Logsdon said. 'It’s a decent question, and I think it’s an unanswered question.'" (My answer to this question, for what it's worth, is here.)

"It was the sound of wonder and foreboding. Nothing would ever be quite the same again -- in geopolitics, in science and technology, in everyday life and the capacity of the human species." On the eve of its fiftieth anniversary (Oct. 4), the NYT remembers the Sputnik launch. "It was an unprepossessing agent of alarm. A simple sphere weighing just 184 pounds and not quite two feet wide, it had a highly polished surface of aluminum, the better to reflect sunlight and be visible from Earth...The Russians clearly intended Sputnik as a ringing statement of their technological prowess and its military implications. But even they, it seems, had not foreseen the frenzied response their success provoked."

"For Barbara Morgan and her crewmates, class is in session." Congrats to schoolteacher Barbara Morgan, who rocketed off into space today aboard the Endeavor, fulfilling both a lifelong dream and the mission originally set for Christa McAullife and the Challenger crew 21 years ago. Godspeed.

"'We're thrilled to have identified clear signs of water on a planet that is trillions of miles away,' said study leader Giovanna Tinetti of the Institut d'Astrophysique de Paris in France." Scientists discover clear signs of existing water well outside the solar system at HD 189733b, a Jupiter-ish gas giant in the Vulpecula constellation, 64 light years away. "The researchers found that the planet absorbed starlight in such a way that could only be explained by the presence of water vapor in its atmosphere."

NASA prepares a probe, named Phoenix, to dig for water on Mars. "Upon reaching Mars in May 2008, the spacecraft is to land just as the winter ice begins to recede around the polar cap."

"I have long wanted to go into space, and the zero-gravity flight is the first step toward space travel." Physicist Stephen Hawking experiences zero gravity aboard the Vomit Comet. "Hawking said he hoped his flight would provide a boost for commercial spaceflight, in line with his oft-expressed belief that humanity's future depended on moving beyond Earth...'I think that getting a portion of the human race permanently off the planet is imperative for our future as a species. It will be difficult to do this with the slow, expensive and risk-averse nature of government space programs,' Hawking said, working in a veiled reference to NASA. 'We need to engage the entrepreneurial engine that has reduced the cost of everything from airline tickets to personal computers.'" I'm in full agreement...far be it from me to differ with a man as intelligent, knowledgeable, and solid on the mic as Mr. Hawking.

"Because of its temperature and relative proximity, this planet will most probably be a very important target of the future space missions dedicated to the search for extraterrestrial life. On the treasure map of the Universe, one would be tempted to mark this planet with an X." The big news today, of course: Astronomers announce the discovery of an earth-like planet, Gliese 581c, at the galactically tiny distance of 120 trillion miles (20.5 light years) away. (For the stargazers, Gliese 581 is a red dwarf "located in the northeastern part of constellation Libra.") Of course, we still don't know if we even have to go that far to find extraterrestrial life -- Europa, Mars, Ganymede, and Callisto all still pose unresolved questions. Nevertheless, it's an exciting moment in our history to discover the first planet far afield that might possibly be inhabited (and inhabitable)...and even more exciting to know that there'll assuredly be many more to come. The stars, our destination!

A faraway Jupiter-like gas planet, HD 209458b, is found (by some) to have water in its atmosphere. I saw this on Blivet on Friday and spent the weekend dreaming about it: If my sleeping brain can be trusted, HD 209458b has winged, eel-like space reptiles cavorting amidst the gaseous clouds there. Alas, my subconscious makes for a lousy exobiologist: "[A] Jupiter-like gaseous planet such as this one, as opposed to a rocky one like Earth, is highly unlikely to harbour any kind of life." Well, damn.

"What would happen if an astronaut became mentally unstable in space and, say, destroyed the ship's oxygen system or tried to open the hatch and kill everyone aboard?" Yet another use for that miracle of miracles, duct tape, is discovered: restraining crazy astronauts in space. Hmmm. Somehow I doubt that would've worked on Ash.

"To not utilize that station the way I think it ought to be utilized is just wrong." Forty-five years to the day after his historic orbit, space pioneer and former US Senator John Glenn makes a case for the International Space Station.

Anna Nicole Smith died after what looks to be a casino bender, and, just in time for Valentine's Day, Houston has a problem with crazy-jilted astronauts. I have very little to say about either of these stories, but since they feverishly consumed most of this week's news cycles, here they are.

The source of that Hawaii link above deserves its own posting: DISCOVER magazine presents the Top 100 science stories of 2006.

New photos released by NASA from the Mars Global Surveyor seem to suggest the possibility of surface water on Mars, which would make any attempt to visit -- or colonize -- the red planet considerably easier (although, obviously, it's still no walk in the park.)

In "world of the future" news, NASA announces it plans to establish a permanently-staffed base camp on the moon by 2024, preferably at one of its poles. (Here's the rationale.) A moonbase within 18 years? I'm all for it...just keep an eye out for monoliths and make sure Sean Connery runs a tight ship.

Using the thankfully soon-to-be-refurbished Hubble, astronomers find more evidence of "dark energy" in the early universe working along the lines of Einstein's famous fudge factor, the cosmological constant, to combat a gravitational crunch. "'Dark energy makes us nervous,' said Sean Carroll, a theoretical physicist at the California Institute of Technology who was not involved in the supernova study. 'It fits the data, but it's not what we really expected.'"

As threatened in the past, Dubya has apparently signed a new National Space Policy that heavily emphasizes the weaponization of space. "Theresa Hitchens, director of the nonpartisan Center for Defense Information in Washington, said that the new policy 'kicks the door a little more open to a space-war fighting strategy' and has a 'very unilateral tone to it.'"

If you believe they put "a" man on the moon, then there's nothing up my sleeve, and nothing is cool. Also, you'll have no problem with the recent update to Neil Armstrong's famous first words there. Score one for the lunar grammarians.

Sorry, Virginia (and all the other kids out there who just memorized the solar system): As the dust dies down at the recent astronomer's conference, word comes to light that Pluto has in fact been demoted to "dwarf planet," a status it'll hold with UB313 (Xena) and Ceres.

At a meeting of 2,500 astronomers in Prague to determine the appropriate definition of "planet" (in part due to the Xena challenge), it appears Pluto might soon be reclassified as a "dwarf planet" (as opposed to a "terrestrial planet" (Earth, Mars) or a "gas giant planet." (Jupiter, Saturn)) rather than fully being demoted to non-planet status. Said one proponent of the plan: "I think we have done something that will make the Plutocrats and the children of the United States happy."

"'We certainly have not convinced the community, and that's been a little bit disappointing,' said David McKay, a NASA biochemist and leader of the team that started the scientific episode." Ten years later, CNN summarizes the simmering scientific dispute over a Martian meteorite, and the possible (albeit now seemingly quite unlikely) signs of life within.

"'This is the cleanest orbiter than anyone ever remembers seeing," Griffin said in a post-landing news conference. He added that with Discovery's successful completion of all its on-orbit tasks, it had finished 'as good a mission as we have ever flown.'" Congrats to the crew of Discovery on a safe and successful landing.

"Blue Origin proposes to launch its reusable launch vehicles (RLVs) on suborbital, ballistic trajectories to altitudes in excess of 325,000 feet (99,060 meters) from a privately-owned space launch site in Culberson County, Texas." Some details emerge about the New Shepard Reusable Launch System, currently being developed by Jeff Bezos' Blue Origin, where -- full disclosure -- one of my best and smartest friends from college is currently employed. "Also on the group's to do list at the site is putting in place a vehicle processing facility, a launch complex and vehicle landing and recovery area, as well as an astronaut training facility, and other minor support amenities."

A belated happy 230th Independence Day to you and yours, and here's hoping the recent spate of scary news (North Korean missiles, incipent war in Gaza) didn't detract too much from the festivities in your parts. (Also, with regards to more joyous fourth of july rocket launches, congrats to the crew of Discovery STS-121 on a successful return to space yesterday.)

Also in news-of-the-future, China sets a lunar launch date of 2024.

"'It is important for the human race to spread out into space for the survival of the species,' Hawking said. 'Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers we have not yet thought of.'" Stephen Hawking makes the case for colonies in space. And Stephen Hawking is a very smart man (and, of course, not a bad MC.)

The WP takes a gander at the Southern African Large Telescope (SALT), which "can see 13 billion years back in time, nearly to the big bang. With its 10-by-11-foot hexagonal mirror -- the largest of its type in the world -- SALT concentrates the faintest, most distant light in the universe. If a candle were to flicker on the moon, SALT could detect it."

The European Space Agency releases the first new pics from their recent "Express" mission to Venus. The Venus Express probe entered Venusian orbit on Tuesday.

A very happy belated birthday to my sister Gillian, who turned 27 yesterday. (We celebrated on Monday, but, as y'all might know, I haven't posted here since then.) Update: Also, a very happy Yuri's Night to you and yours -- tonight is the 45th anniversary of cosmonaut Yuri Gagarin's first-ever trip into space, as well as the 25th anniversary of the first space shuttle mission. (By way of Blivet.)

After discovering a disk of gas, dust, and rubble orbiting a pulsar, astronomers believe they've figured out how planets are made. "It shows that planet formation is really ubiquitous in the universe. It's a very robust process and can happen in all sorts of unexpected environments."

"'The idea is to look at Mars and not think of it as a mysterious alien place,' Christensen said." Along the lines of Google Moon, one can now journey to Google Mars.
