Asteroid 2010 KQ: Probably a Rocket Body

A small asteroid-like object has been discovered in an orbit about the Sun that is so similar to the Earth's orbit that scientists strongly suspect it to be a rocket stage that escaped years ago from the Earth-Moon system. The object was discovered on May 16, 2010 by Richard Kowalski at the Catalina Sky Survey, and has subsequently been observed by many observers, including Bill Ryan (Magdalena Ridge Observatory) and Peter Birtwhistle (England). It was given the asteroid designation 2010 KQ by the Minor Planet Center in Cambridge Massachusetts, who identified its orbit as being very similar to that of the Earth. Orbit refinements by JPL's Paul Chodas and amateur astronomer Bill Gray have shown that this object was very close to the Earth in early 1975, but the trajectory is not known with enough accuracy to associate the object with any particular launch. Nevertheless, scientists do not expect that a natural object could remain in this type of orbit for very long because of its relatively high impact probability with the Earth. In fact, an analysis carried out by Paul Chodas suggests that 2010 KQ has a 6% chance of impacting the Earth over a 30-year period starting in 2036.

Near-infrared spectral measurements of this object carried out by S.J. Bus (University of Hawaii) using the NASA IRTF telescope on Mauna Kea, Hawaii, indicate that its spectral characteristics do not match those of any of the known asteroid types, and in fact are similar to those of a rocket body. The object's absolute magnitude (28.9) also suggests that it is only a few meters in size, about the size of a upper stage. Additional observations over the coming months should allow scientists to discern how strongly solar radiation pressure affects the object's motion, a result that could help distinguish a solid, rocky asteroid from a lighter man-made object.

Even in the unlikely event that this object is headed for impact with the Earth, whether it is an asteroid or rocket body, it is so small that it would disintegrate in the atmosphere and not cause harm on the ground.

Mientras tanto el mundo avanza

Y si, aca discutimos por el Colon, si le damos la silla, sino, etc, mientras tanto

Los cientificos estan informando que han hecho una celula viva de ADN que fue sintetizado en laboratorio, No es un organismo sintetico, aun, pero el resultado es un importante paso.......

IN BRITAIN, after the Daily Telegraph broke the story last year that members of parliament had blatantly fiddled expenses, all the media had a field day. In Japan details are leaking out of a large secret fund kept in a black box near the prime minister’s office that for decades has been used to curry political favours, including, it is said, among journalists and television commentators. Tellingly, the Japanese media is reacting to the scandal like the three wise monkeys of Nikko: see no evil, hear no evil, speak no evil.

The existence of the slush fund has long been known to insiders. But details of its size and the way it was spent were unknown to the public until Hiromu Nonaka, a former chief cabinet secretary, revealed last month that from 1998-99 he spent up to ¥70m ($600,000 at the exchange rate of the time) a month from his secret little piggy bank. That included ¥10m to the prime minister, ¥10m to politicians in the then-ruling Liberal Democratic Party (LDP), and more scattered among political commentators and opposition-party members, including those going on trips to North Korea.

Mr Nonaka, who is 84, says he made the confession because he did not want to carry the secret to the grave about what he rightly refers to as taxpayers' money. But he may also have been making mischief for the Democratic Party of Japan (DPJ), which drove the LDP from power last year. It has since come to light that the new government of Yukio Hatoyama, elected on a platform of transparency and accountability, has been dipping into the cabinet office’s slush fund as freely as its LDP predecessors.

On May 14th Hirofumi Hirano, Mr Hatoyama’s chief cabinet secretary, confirmed, in answer to a largely unreported parliamentary question by the Japanese Communist Party, that he had withdrawn ¥360m ($3.8m) from the fund between September and March, and spent all but ¥16m. He claimed to have returned the unused portion to the exchequer. But, he also said, for the time being he did not intend to disclose what the money was spent on, nor did he expect to stop using the pot.

Mr Hirano also appeared reluctant to investigate the outgoing LDP administration led by Taro Aso, which raided the fund last year just before it handed over power to Mr Hatoyama. Two days after the election, and two weeks before leaving office, it withdrew an impressive ¥250m.

Some people might shrug off the fund as part of the old Japanese tradition of gift-giving, admittedly involving some pretty generous presents. Mr Hirano says money is necessary to gather information “for the benefit of the nation”. But for a government that has long promised to dig up the “buried treasure” hidden in government accounts in order to improve shaky public finances, it is extraordinary that it, too, is taking such brazen advantage of this darkest of slush funds. Just as extraordinary, not to mention suspicious, is the impressive silence from most of the powerful mass media. More evidence, if it were needed, of its central role in Japan's longstanding political dysfunction.

One in eight to cut cable and satellite TV in 2010
NEW YORK (CNNMoney.com) -- Despite rising cable and satellite TV prices and easy access to streaming TV and movies on the Internet, few consumers have cut the cord. But that looks like it's about to change.

pero el mejor parrafo

"Just like with telephone land lines, it's going to become hard to sell pay TV to anyone under 30," Vittore said.
