LOS ANGELES - The Phoenix spacecraft has tasted Martian water for the first time, scientists reported Thursday.
By melting icy soil in one of its lab instruments, the robot confirmed the presence of frozen water lurking below the Martian permafrost. Until now, evidence of ice in Mars' north pole region has been largely circumstantial.

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.

I never quite realized how big our moon is compared to our planet. I had read that this ratio was unusual when compared with other moons and planets, but this video illustrates the size relationship from a new point of view.

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.
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.

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?

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.
