Tiny Mimas, huge Saturn
That's Mimas in front with Saturn filling the background. As a reference, Mimas is 392 kilometers in diameter, or 244 miles. That's pretty small, but it's still a decent-sized object, and it really highlights the immenseness of its mother planet.
Someday, I'm sure, we will have humans traveling to these sections of our solar system, and hopefully such sights will be seen with actual human eyes, live and in full color. Perhaps such flights will even become commonplace, though I'm sure that will be well after my time.
But I hope we get there, eventually.

Fighting panda extinction
HONG KONG - A giant panda named Peace bit a park keeper's left leg while he was laying bamboo leaves in the animal's pen at a Hong Kong amusement park, officials said Tuesday.
The worker was recovering well in hospital after the attack at Ocean Park, which has four giant pandas from China, park spokeswoman Christie Lau said.
Lau said park officials were still investigating the Nov. 30 incident involving the male panda, whose name, An An, means "peace" in Mandarin.
They are wild animals, and they will act like it from time to time. And I don't think they're very cute, either.

Choosing the wrong article
I'm not really a prescriptivist, but the choice between "a" and "an" is pretty clearly determined by the sound of the word or letter following it, not the letter itself. As such, this collection of Christmas tunes should have been titled "An R&B Christmas" instead.
Don't get me wrong, I'm not going to claim the world is coming to an end over such small errors in English, but I always thought the distinction between "a" and "an" was rather instinctive with native speakers. Perhaps I'm mistaken, or perhaps this CD was manufactured in some place where English is not the primary or preferred language.
Yep, I was right. I just checked. This CD was made in Quebec.

Fighting panda extinction
BEIJING - A college student in southern China just needed a hug, but he probably shouldn't have picked a panda for his warm and fuzzy moment.
Instead of a hug, the panda bit the student after he broke into the animal's zoo enclosure.
...
The official Xinhua News Agency reports the hospitalized student later said the panda was so cute and cuddly he never expected to be bitten.
Remember, pandas are wild animals, not teddy bears! They don't love you, and they never will, no matter how much you want to save them and hug them and make them breed when they don't want to!
If you want love, save a dog from the pound. Or just be a friend to someone who needs one.

Stretching a euphemism
See, I used a euphemism. I used dispatch rather than kill or slay. That seems more apt to me than what an SAPD sergeant said to explain one of his fellow officer's actions.
SAN ANTONIO -- A San Antonio police officer shot and killed a dog Thursday during a search for two robbery suspects on the city's west side.
...
When some other officers surrounded the home, the homeowner's dog came out and charged at one of the officers, said Sgt. Lloyd Jackel of the San Antonio Police Department.
"He hollered at the owner to secure the dog three times," Jackel said. "The owner was attempting to come out and do that, but the dog got too close and the officer felt threatened, (so) he had to come out and euthanize the dog." [emphasis added]
(from KSAT-12)
Euthanize normally means to put an animal out of its misery or to put it down in a painless manner. Now, don't get me wrong, I don't blame the police officer for shooting the dog, but I don't think euthanize is the right word to use here. The bullet probably hurt a bit, and I don't think the dog was suffering to begin with. So, if I were the sergeant, I would have just said, "He had to come out and kill the dog for the safety of everyone involved." I think that's a good enough word.

Language quote of the day
A bit of Platonism going on there, but that's no surprise. A lot of old Western thinkers loved that ancient Greek thinker.The philosopher knows only the significance of words, but the significance of things is far more excellent than that of words, because the latter was established by usage, but Nature dictated the former. ... The unsubstantial word is the sign of man's perceptions; the thing is a resemblance of the divine Idea.

Boo!
So much goes into a good fright flick. To me, it's all about the suggestion. Your own mind can always create a scarier monster than anything the special effects department can dream up with latex. Movies that create a sense of true dread, that set up a scenario where you can feel the fear without being overwhelmed by monsters and gore, will win me every time.
I feel that one of the most overlooked elements of a great horror movie is the dialogue. Dramas and comedies are expected to have eloquent or snappy dialogue, but horror-movie lines often get lost in the avalanche of fake blood. Yet a great horror-movie line can chill you to the bone and stay with you for months. It can also break your heart.
Here are my favorite scary movie lines, from Aliens:
Newt: My mommy always said there were no monsters - no real ones - but there are.
Ripley: Yes, there are, aren't there?
Newt: Why do they tell little kids that?
Ripley: Most of the time it's true.
Still creeps me out, even twenty years later.

Doomed moon
This moon is doomed. Mars, named for the Roman god of war, has two tiny moons--Phobos and Deimos--whose names are derived from the Greek for fear and panic. These Martian moons may well be captured asteroids originating in the main asteroid belt between Mars and Jupiter or perhaps from even more distant reaches of the solar system.
The larger moon, Phobos, is a cratered, asteroid-like object in this stunning color image from the Mars Reconnaissance Orbiter. Phobos orbits so close to Mars that gravitational tidal forces are dragging it down. In 100 million years or so, Phobos likely will be shattered by stress caused by the relentless tidal forces, the debris forming a decaying ring around Mars.

Answering the quiz
It's a rocket.
Here's the caption to the photo, which can be found in NASA's image galleries.
Good work for the betterment of mankind.A welder at NASA's Glenn Research Center (GRC) grinds welds on an Ares I-X rocket segment being readied for shipment to Kennedy Space Center. Ares I is part of the next generation of launch vehicles that will return humans to the moon and later take them to Mars and other destinations. Ares I is an in-line, two-stage rocket configuration topped by the Orion crew vehicle and its launch abort system. In addition to the vehicle's primary mission -- carrying crews of four to six astronauts to Earth orbit -- Ares I may also use its 25-ton payload capacity to deliver resources and supplies to the International Space Station, or to 'park' payloads in orbit for retrieval by other spacecraft bound for the moon or other destinations.
The Ares I-X is scheduled for a test launch in 2009. GRC is designing and manufacturing several components of the test rocket, including the upper stage mass simulator and the service module and spacecraft adapter simulators.

Calling B.S. on a comic book character
By their very nature, comic book characters defy conventions, timelines, physics, metaphysics, religions, common sense, and willing suspensions of disbelief. So I should just relax when I note an inconsistency in a comic book and move on. Right?
But this time I couldn't.
I was reading a Marvel comic book to my son, one in which the Avengers come across the Marvel version of Hercules. There's a misunderstanding of epic proportions because Hercules only understands Greek (helpfully translated by the editor), and the demigod ends up fighting the Hulk for a while before Captain America -- who understands a little Greek from the time he spent in the country during World War II -- convinces him that he needs to team up with the Avengers to stop a giant, rampaging Cerberus. An understanding is born, and the three-headed monster is defeated.
No problem there. Standard Marvel fare. But what bothered me just a touch was the language Hercules used. Rendered in [bracketed English] so you can tell it's a translation of Greek, the language was presented in mock heroic tones with Hercules speaking of great feasts and feats of strength and general pleasure in good fights. And what caught my eye was a mild oath uttered by the ancient Grecian.
It was zounds.
I remembered from my studies of medieval and Renaissance literature that zounds is an abbreviation of "God's wounds," an exclamation used to express suprise or anger. It was used in that sense by Hercules in the Marvel comic book, but "God's wounds" is an allusion to the wounds suffered by Jesus Christ during the crucifixion. It's an oath born out of Christianity, and one that would be familiar in Christendom, but hardly in ancient Greece. Even if Hercules were real.
I know, I know -- it's a comic book. I should relax. Actually I am pretty laid back about it. It really doesn't bother me that much, but it did give me a good prompt for a blog post.
What's next? Thor screaming "Gadzooks"?

Walking in space, Chinese style
BEIJING - Chinese celebrated their nation's first spacewalk Saturday, gathering at outdoor TV screens to cheer live video of the milestone for a program that has ambitions of building a space station and challenging the U.S. and Russia in off-world exploration.
...
The spacewalk was mainly aimed at testing China's mastery of the technology. Mission commander Zhai Zhigang's sole task was to retrieve a rack attached to the outside of the orbital module containing an experiment involving solid lubricants.
...
In step with its growing list of achievements, China's military-backed space program has grown progressively less secretive, and officials have hinted in recent days at a desire for greater cooperation with other nations. China plans to mass-produce the next version of the Shenzhou ship to service a future space station and says it may make such missions available to other countries.
As with anything about China, I have mixed feelings about this achievement. I think it's great that other nations are at least showing an interest in working together to advance humanity's chances of becoming a space-faring species. On the other hand, this is China.

Calling B.S. on an insane saying
Review the history
In order from highest to lowest, the 10 U.S. cities with the highest poverty rates are: Detroit, Buffalo, Cincinnati, Cleveland, Miami, St. Louis, El Paso, Milwaukee, Philadelphia and Newark.
The last time the following cities elected mayors who weren’t Democrats was: Detroit, 1961; Buffalo, 1954; Cincinnati, 1984; Cleveland, 1989; St. Louis, 1949; Milwaukee, 1908; Philadelphia, 1952, and Newark, 1907.
Albert Einstein once defined insanity as “doing the same thing over and over again and expecting different results.”
C. F. Eckhardt, Seguin
No, no, no, no, no! I am tired of hearing this stupid saying! Please, quit using it!
Doing the same thing over and over again and expecting different results is not the definition of insanity. The definition of insanity is really "the condition of being insane; a derangement of the mind". I know, I know, people like to use that line repeated by Mr. Eckhardt of Seguin because it makes for good hyperbole, but that is not an accurate saying, and it was never uttered by any person such as Einstein.
In fact, the line actually is this: "Insanity is doing the same thing, over and over again, but expecting different results." It's from a book by an American writer named Rita Mae Brown. It may have been a clever line at the time Ms. Brown published her book, but it's not anymore. It's overused and it's trite. Please, let's not utter it again.
Rant over.

Calling B.S. on Star Trek
I'm with T-Rex on this one. Star Trek made time travel too easy for it to be a compelling plot point in later episodes, and T-Rex is right to wonder why they don't do it all the time!
My own personal pet peeve with Star Trek concerns warp travel. If it takes seven (or twelve or twenty) days to get to the next starbase at warp three but only three seconds at warp nine, then why not go full speed all the time! C'mon, it makes no sense to be dawdling about the universe in a huge ship with a well-trained crew when you could be handling crises in an instant!
Captain, we need to dock at Station 33.3 for vital repairs.
Very good. Set a course. Warp five. Engage.
But Captain, that will take us 23 hours. We can get there in like ten minutes if we just go warp nine.
Oh. OK, I forgot. Let's do it then. Warp nine. Engage.
Makes sense to me.

"Talk about amazing animal magnetism..."
A study of Google Earth satellite images has revealed that herds of cattle tend to face in the north-south direction of Earth's magnetic lines.
Staring at cows may not equal the thrill of spotting celebrities in public or rubbernecking at car accidents, but the researchers found nonetheless that our bovine friends display this strange sixth sense for direction.
Their field observations of red and roe deer also showed those animals facing toward magnetic north or south.
I wonder if the sun's path has anything to do with this, like helping warm up the large animals.
Oh, by the way, I object to Jeremy Hsu of Live Science characterizing automobile accidents as thrilling.

Asking for a new term
I think the problem here is the use of the word "quantum" to describe this kind of teleportation. To most people who aren't scientists, "quantum" means something akin to large or great or awesome. A "quantum leap", to the laity, means a big change.
So, to avoid the confusion demonstrated in the xkcd comic, perhaps scientists might think about renaming the concept. Instead of "quantum teleportation," which may be more accurate, perhaps they could refer to "particle teleportation," or something similar.
That would probably clear things up a bit for the masses. Or at least for journalists.

"NASA drops plan to fly new spaceships by 2013"
CAPE CANAVERAL, Fla - NASA has abandoned plans to get its replacement for the retiring U.S. space shuttles into service by 2013 because of a lack of additional funds and technical issues, officials said on Monday.
The U.S. space agency had hoped to fly astronauts to the International Space Station aboard a new spaceship called Orion as early as September 2013, well before its formal deadline or goal of March 2015.
The faster the better. It's good they're shooting to get this project done early, though they seem to have suffered a setback.
I would hate to rely on Russia for anything, but if we had to rely on them for something, I suppose help in the field of space exploration might be our safest bet."The window of opportunity for us to accelerate Orion has closed," program manager Jeff Hanley at NASA's Johnson Space Center in Houston told reporters during a conference call.
The United States will be without a means to transport people to and from space after the shuttle fleet is retired in 2010 until the new ships are ready to fly. It intends to rely on Russia to ferry crews to the space station and on private companies to deliver cargo during the gap.
NASA had hoped to minimize the gap, but additional funding to do so has not been approved by the U.S. Congress.
The agency now hopes to be able to fly an Orion crew to the International Space Station by September 2014.
Let's hope so.

Finding lakes on Titan
A giant, glassy lake larger than North America's Lake Ontario graces the south pole of Saturn's largest moon Titan, new research confirms.
"This is the first observation that really pins down that Titan has a surface lake filled with liquid," said lead researcher Robert Brown of the University of Arizona's Lunar and Planetary Laboratory in Tucson.
Called Ontario Lacus, the lake extends 150 miles (235 kilometers) and covers an area of about 7,800 square miles (20,000 square kilometers). The lake structure is filled mostly with methane and ethane, hydrocarbons that are gases on Earth but liquid on the bone-chilling surface of Titan.

"Belgium government collapses, country next?"
Language matters. Belgium is home to the executive branch of the European Union, and now it's existence is threatened by differences in tongues. Let's hope other nations don't suffer the same fate.BRUSSELS, Belgium - Belgium's government collapsed Tuesday, unable to resolve an enduring divide over more self-rule for the country's Dutch and French-speakers. The gap was so wide the premier suggested the end of Belgium as a country was looming.
King Albert II immediately began political discussions with lawmakers to try to resolve the situation, talks expected to take several days. He did not formally accept the resignation of government offered by Premier Yves Leterme late Monday, so Leterme's government stays on in a caretaker capacity for now.
In an unusual declaration, the premier said Belgium's constitutional crisis stems from the fact that "consensus politics" across Belgium's widening linguistic divide no longer works.
More ice!
From Andrea Thompson at Space.com:
Keep trenching, Phoenix! You've got a dig czar on your side.NASA's Phoenix Mars Lander used its robotic arm to expose more of the hard icy layer just below the Martian surface so that it can more easily gather a sample of the material for analysis.
The trench, informally called "Snow White," was about 8 by 12 inches (20 by 30 centimeters) after digging by the arm Saturday. Mission controllers sent commands to the spacecraft Monday to further extend the length of the trench by about 6 inches (15 centimeters).
Scientists said tests in a lab on Earth suggested more area must be exposed in order to collect a proper sample.
"Right now, there is not enough real estate of dark icy soil in the trench to do a sample acquisition test and later a full-up acquisition" for the Thermal and Evolved-Gas Analyzer (TEGA), said Ray Arvidson, Phoenix's "dig czar," from Washington University in St. Louis. The TEGA instrument bakes samples of the Martian dirt in tiny ovens and analyzes the vapors given off to determine the composition of the regolith.

Taking our words
The original story is at the Dallas Morning News. Here's the gist:
A special meeting about Dallas County traffic tickets turned tense and bizarre Tuesday afternoon.
County commissioners were discussing problems with the central collections office that is used to process traffic ticket payments and handle other paperwork normally done by the JP Courts.
Commissioner Kenneth Mayfield, who is white, said it seemed that central collections "has become a black hole" because paperwork reportedly has become lost in the office.
Commissioner John Wiley Price, who is black, interrupted him with a loud "Excuse me!" He then corrected his colleague, saying the office has become a "white hole."
That prompted Judge Thomas Jones, who is black, to demand an apology from Mayfield for his racially insensitive analogy.
Mayfield shot back that it was a figure of speech and a science term.
As I assert in the comments section of the Volokh post, people this country seem to want to have a conversation about race. But how can we do that when white people don't know what words they can and can't say? It seems any word can offend (and you won't know it causes offense until it does, and then it's too late to do anything about it), so the white side of the aisle will eventually stop talking altogether and the "conversation" will be one-sided. And how does that help?

Explaining strange asteroid shapes
But what changes the asteroids' shape? Gyula [Szabó from the University of Szeged in Hungary] and his team have shown that asteroids change shape from elongated to roughly spherical due to being impacted during their lifetimes. They are like pebbles on the beach that become worn smooth over many years -- only in space, erosion is caused by small impacts as rocks knock into each other and chip pieces off.
Impact specialist Jonti Horner from the UK's Open University agrees with Gyula. "The results make sense," he says. "Catastrophic impacts create a huge slew of fragment shapes, like the shards of a broken bottle. The debris then are weathered over time and smoothed towards sphericality by small impacts."
Space pebbles. Cool stuff.

Ice on Mars!
When the probe took photos of a ditch it had dug four days before, scientists noticed that about eight small crumbs of a bright material had disappeared. They concluded those crumbs had been water ice buried under a thin layer of dirt that vaporized when Phoenix exposed them to the air.
"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," Phoenix principal investigator Peter Smith of the University of Arizona, Tucson said at a briefing Friday.
Let's hope there are giant aquifers of the stuff deep underground.

Smelling space exploration
During the Apollo missions, the astronauts donned their space suits inside the Apollo Lunar Module cabin, which was then depressurized to allow them to exit the vehicle. Upon the end of EVA, the astronauts would re-enter the cabin in their suits, bringing with them a great deal of dust which had adhered to the suits. Several astronauts reported a "gunpowder" smell and respiratory or eye irritation upon opening their helmets and being exposed to the dust.
[referenced article at Space.com, "Lunar Explorers Face Moon Dust Dilemma" by Leonard David]

Feminists challenge Islamic terrorists
In response to a female questioner, al-Qaida No. 2 leader Ayman Al-Zawahri said in April that the terrorist group does not have women. A woman's role, he said on the Internet audio recording, is limited to caring for the homes and children of al-Qaida fighters.
His remarks have since prompted an outcry from fundamentalist women, who are fighting or pleading for the right to be terrorists. The statements have also created some confusion, because in fact suicide bombings by women seem to be on the rise, at least within the Iraq branch of al-Qaida.
...
Al-Zawahri's remarks show the fine line al-Qaida walks in terms of public relations. In a modern Arab world where women work even in some conservative countries, al-Qaida's attitude could hurt its efforts to win over the public at large. On the other hand, noted SITE director Katz, al-Zawahri has to consider that many al-Qaida supporters, such as the Taliban, do not believe women should play a military role in jihad.
Al-Zawahri's comments came in a two-hour audio recording posted on an Islamic militant Web site, where he answered hundreds of questions sent in by al-Qaida sympathizers. He praised the wives of mujahedeen, or holy warriors. He also said a Muslim woman should "be ready for any service the mujahedeen need from her," but advised against traveling to a war front like Afghanistan without a male guardian.
How bizarre to these Western ears.

"NASA spacecraft successfully lands near Mars pole"
PASADENA, Calif. - A NASA spacecraft plunged into the atmosphere of Mars and successfully landed in the Red Planet's northern polar region on Sunday, where it will begin 90 days of digging in the permafrost to look for evidence of the building blocks of life.
Less than two hours later, the Phoenix Mars Lander beamed back four dozen black-and-white images including one of its foot sitting on Martian soil amid tiny rocks. Others included the horizon of the arctic plain and ground with polygon patterns similar to what can be found in Earth's permafrost regions.
"Absolutely beautiful," said Dan McCleese, a chief scientist at NASA's Jet Propulsion Laboratory. "It looks like a good place to start digging."
I'm sure they will get started in no time. Let's hope the Phoenix mission goes very well.

"Ice-sampling probe set for Sunday landing on Mars"
PASADENA, California (Reuters) - A new chapter in Mars exploration opens on Sunday when a small robotic probe jets down to the planet's arctic circle to learn if ice beneath its surface ever had the right chemistry to support life, mission managers said on Thursday.
NASA approved the mission, known as Phoenix, after the Mars orbiter Odyssey found ice surrounding the polar caps in 2002. Five probes landed near Mars' equatorial zones, including the rovers Spirit and Opportunity, which discovered signs of past surface water. Odyssey found no sign of buried ice around Mars' equator.
"We're going way to the north," said Peter Smith, a planetary geologist at the University of Arizona in Tucson who heads the Phoenix science team.
Good luck to the team running Phoenix.

"Robotic suit could usher in super soldier era"
Rex Jameson bikes and swims regularly, and plays tennis and skis when time allows. But the 5-foot-11, 180-pound software engineer is lucky if he presses 200 pounds — that is, until he steps into an "exoskeleton" of aluminum and electronics that multiplies his strength and endurance as many as 20 times.
...
Jameson — who works for robotics firm Sarcos Inc. in Salt Lake City, which is under contract with the U.S. Army — is helping assess the 150-pound suit's viability for the soldiers of tomorrow. The suit works by sensing every movement the wearer makes and almost instantly amplifying it.
The Army believes soldiers may someday wear the suits in combat, but it's focusing for now on applications such as loading cargo or repairing heavy equipment. Sarcos is developing the technology under a two-year contract worth up to $10 million, and the Army plans initial field tests next year.
And the best line in the story:
"It takes no special training, beyond learning to relax and trust the robot," he said.
When can I get one?

Fighting panda extinction
TOKYO (AFP) - Animal rights activists on Wednesday urged Japan to reject visiting Chinese President Hu Jintao's offer of two pandas, saying the crowd-pleasing animals would be miserable in a zoo.
Hu, trying to reconcile with Japan on the first visit by a Chinese president to Tokyo in a decade, offered to lend a male and a female panda to replace Ling Ling, who died last week at Tokyo's Ueno Zoo.
People for the Ethical Treatment of Animals (PETA) sent a letter to Foreign Minister Masahiko Komura urging Japan to halt the deal.
The US-based rights group noted that the pandas were being leased, not gifted, and estimated the zoo would pay China around one million dollars a year for each animal.
"Pandas are an endangered species, not a commodity to be traded for human amusement," [Not even for gushing journalists?] PETA campaigner Rie Ichikawa said in the letter.
"In honour of the late Ling Ling -- the panda who spent his entire life in a zoo, where he was denied his freedom, the right to choose his own mate, and everything that was natural and important to him -- we urge Minister Komura to declare that no more pandas will be taken from their homes and sentenced to a life at the Ueno Zoo."
So, PETA's problem is the fact that money is exchanging hands? Or is it that the pandas will be miserable in a zoo? Or is it that the pandas are in captivitiy at all? If that's it, then why stop the deal, since the pandas would still be in captivity in China?
Sometimes, I really don't understand PETA or its motivations.

Odd headline of the day
And the story is kind of kooky, too.
WELLINGTON (Reuters) - Peace activists attacked and deflated a large inflatable globe housing a satellite dish at a top secret New Zealand spy base on Wednesday in protest at United States military actions.
The group, calling itself ANZAC Ploughshares, said it cut through fences and razor wire and avoided electronic sensors to slash one of two 30-metre (98-ft) white globes with a sickle at the Waihopai base near Blenheim at the top of the South Island.
The base is described as a satellite communications monitoring facility, but peace campaigners have said it is part of a global signals interception network called Echelon.
"The Echelon spy network including Waihopai, is an important part of the U.S. government's global spy network and we have come in the name of the Prince of Peace to close it down," said Ploughshares in a statement.
I didn't know Jesus advocated sickle work. And I didn't know satellite communications domes in New Zealand were appropriate targets for anti-American sentiment. But I do know that the first three words of the article have got to be the funniest words I've read today.

"Primitive Alien Life May Exist, Stephen Hawking Says"
Alien life may well exist in a primitive form somewhere in our corner of the galaxy, famed astrophysicist Stephen Hawking said Monday.
Given the size of the universe, it is unlikely that Earth is the only planet to develop some sort of life, Hawking told an audience at George Washington University in Washington, D.C. He added that humanity must embrace space exploration, if only to ensure its long-term survival. [Complete agreement here.]
"While there may be primitive life in our region of the galaxy, there don't seem to be any advanced intelligent beings," said Hawking during a lecture as part of a series commemorating NASA's 50th anniversary this year.
...
The probability of primitive life developing on a suitable planet may be extremely low, or it may be high, but aliens intelligent enough to beam signals into space may also be smart enough to build civilization-destroying weapons like nuclear bombs, he said. More likely, he added, is that primitive life is likely to develop, but intelligent life as we know it is exceedingly rare.
"We don't appear to have been visited by aliens," Hawking said, adding that he discounts reports of UFOs. "Why would they only appear to cranks and weirdoes?"
'Nuff said.

"NASA extends Saturn mission for another 2 years"
PASADENA, Calif. - NASA says it is extending the international Cassini mission that is touring Saturn and its moons for another two years.
The space agency announced the extension Tuesday. Since 2004, the unmanned probe has beamed back about 140,000 images. Its prime mission is slated to end in July.
The agency says the $160 million extension will allow Cassini to make 60 more revolutions around the ringed planet and fly by its largest moon, Titan, and four other satellites.
The Cassini mission has yielded precious information about Saturn and its moons that have astoundingly advanced our knowledge of the solar system. I'm glad it is being extended. The success of this mission and the gains obtained by the Mars rovers should be sources of pride for NASA, the United States of American, and all of humanity.

Stating the obvious
"Forecast: Big quake likely in Calif."
LOS ANGELES - California faces an almost certain risk of being rocked by a strong earthquake by 2037, scientists said Monday in the first statewide temblor forecast.
New calculations reveal there is a 99.7 percent chance a magnitude 6.7 quake or larger will strike in the next 30 years. The odds of such an event are higher in Southern California than Northern California, 97 percent versus 93 percent.
"It basically guarantees it's going to happen," said Ned Field, a geophysicist with the U.S. Geological Survey in Pasadena and lead author of the report.
No kidding. Really, with a difference of 97 and 93 percent, does it really matter where you live in California? Just enjoy the weather and get ready for the shaking.

Denigrating husbands
A new study from the University of Michigan shows that having a husband creates an extra seven hours of extra housework a week for women. But a wife saves her husband from an hour of chores around the house each week.
"It's a well-known pattern. There's still a significant reallocation of labor that occurs at marriage -- men tend to work more outside the home, while women take on more of the household labor," said Frank Stafford, of the university's Institute for Social Research (ISR), who directed the study.
...
The researchers studied diaries to assess how people spent their time and questioned men and women about how much time they spend cooking, cleaning and doing basic work around the house.
They found that young single women did the least amount of housework, at about 12 hours a week. Married women in their 60 and 70s did nearly twice that amount, while women with more than three children spent 28 hours a week cleaning, cooking and washing. [emphases added]
I haven't seen the original study, but I wonder if it measured time spent mowing, cutting limbs, working on the car, building shelves, and other work around the house that might be left up to the husband more often than not.

"Shock absorbers may fix rocket shaking"
For nearly half a year, NASA's No. 1 technical problem in designing its Ares I rocket, which will eventually propel astronauts back to the moon, has been a sound wave vibration problem from its solid rocket motors.
If the vibrations hit the right frequency, they could potentially shake the astronauts to death — or at the least make it impossible for them to work. The astronauts would be in the Orion crew capsule launched on top of the Ares.
The leading solution is to put weight on springs in parts of the bottom end of the rocket and underneath astronauts' seats to dampen the vibrations. Think MacPherson struts, said Garry Lyles, who heads a NASA team working on the problem.
"These are actually absorbers that are used in vehicles today, especially one-ton and 1 1/2-ton pickup trucks," Lyles said in a Thursday telephone news conference.
[Insert obligatory joke about it not being rocket science here.]

"NASA cut means no roving for Mars rover"
LOS ANGELES - Scientists plan to put one of the twin Mars rovers to sleep and limit the activities of the other robot to fulfill a NASA order to cut $4 million from the program's budget, mission team members said Monday.
...
Both rovers were originally planned for three-month missions at a cost of $820 million, but are now in their fourth year of exploration. It costs NASA about $20 million annually to keep the rovers running.
I hate to see them limited or shut down now, especially since they've performed well beyond expectations. They are truly one of NASA's triumphs.
UPDATE: NASA has changed its mind.
LOS ANGELES - NASA has no plans to turn off either of the healthy twin Mars rovers to make up for cost overruns faced by a big new rover slated to fly to the Red Planet next year, the space agency said Tuesday.
In a rare move, NASA said it rescinded a letter sent last week to the Jet Propulsion Laboratory in Pasadena that directed budget cuts to the Mars exploration program, including a $4 million reduction from the rovers project.
Good move.

R.I.P. Arthur C. Clarke
COLOMBO, Sri Lanka - Arthur C. Clarke, a visionary science fiction writer who won worldwide acclaim with more than 100 books on space, science and the future, died Wednesday in his adopted home of Sri Lanka, an aide said. He was 90.
Clarke, who had battled debilitating post-polio syndrome since the 1960s and sometimes used a wheelchair, died at 1:30 a.m. local time after suffering breathing problems, aide Rohan De Silva told The Associated Press.
Clarke was regarded as a technological seer as well as a science-fiction writer, and was known as "the godfather of the telecommunications satellite."
Not only do we have him to thank for some great science fiction, but we also have him to thank for modern communications.
Requiescat in pace, old visionary.

"South Korea changes first astronaut"
Seriously, though, it seems that the first South Korean astronaut was disqualified by the Russians for--
--reading.
The wrong stuff.
SEOUL, South Korea - South Korea said Monday a female engineer would become the country's first person in space by going aboard a Russian spacecraft, after Moscow rejected Seoul's first choice because he violated reading rules during training.
The Ministry of Education, Science and Technology said at a news conference that Yi So-yeon will replace Ko San as the country's choice to fly on a Russian Soyuz capsule to the International Space Station in early April.
...
The Russian authorities said Ko took a book out of the [space training] center without permission and sent it to his home in South Korea in September, Lee [Sang-mok, a senior ministry official] said. Ko later returned the book, explaining he accidently sent it home together with other personal belongings, Lee added.
In February, Ko again violated a regulation by getting a book from the center through a Russian colleague — material he was not supposed to read, Lee said. Officials did not give details about the book's contents, but South Korean officials portrayed both of his infractions as minor. [emphasis added]
I wonder what that book was about.
