October 31, 2006.08:36 SPACE: NASA to announce Hubble plans
Quote:
" Administrator Michael Griffin could turn astronomers' Halloween into Christmas with an announcement on whether he will send astronauts on a final mission to repair the Hubble Space Telescope.
The announcement was expected Tuesday on whether he will prolong the life of an instrument that has captured some of the most spectacular images of the universe.
"It's a bit like we know there is a big present under the Christmas tree and we have no idea what's in it," said Matt Mountain, director of the Space Telescope Science Institute in Baltimore, which coordinates use of Hubble.

October 27, 2006.12:59 SCIENCE: Ancient human footprints found in Mexico
Quote:
"-- Ancient human footprints discovered in the Mexican desert may be among the oldest in the Americas, researchers said on Wednesday.
The 13 footprints found in Cuatro Cienegas in the northern state of Coahuila are fossilized in stone less than an inch deep and are around the age of the oldest known footprints in North or South America.
"We believe they could be between 10,000 and 15,000 years old," said archeologist Yuri de la Rosa. "The research we have done on Cuatro Cienegas shows the presence of hunters and gatherers in the Coahuila desert beginning 10,000 years ago."

" NASA satellite data shows the region east of the Andes Mountains in Argentina experience the Earth's most intense thunderstorms.
The data from NASA's Tropical Rainfall Measuring Mission, or TRMM, satellite, surprisingly also show some semi-arid regions can generate powerful storms, including the southern fringes of the Sahara, northern Australia, and parts of the Indian subcontinent. In contrast, rainy areas such as western Amazonia and Southeast Asia experience frequent storms, but few are severe.

"The work is very preliminary, but it could herald an era of effectively invisible "cloaked" devices, says study senior author David Smith of Duke University in Durham, N.C.
A prototype so far only hides objects from microwaves, not from visible light, so the human eye can still see the objects. But scientists say it shows the technology is feasible.
Here's how it works: Electromagnetic waves scatter and reflect when they strike objects, and the eye picks up this reflection to see. The new technology relies on materials that theoretically can bend electromagnetic waves, including visible light, around objects as if nothing were there.
Scientists created a cylinder, or "cloak," about 5 inches across, consisting of 10 fiberglass plates precisely etched with U-shaped copper divots to cancel reflections and shadows from microwaves.
October 19, 2006.05:27 SPACE: New image gives insight into colliding galaxies
A seemingly violent collision of two galaxies is in fact a fertile marriage that has birthed billions of new stars, and an image released on Tuesday gives astronomers their best view yet.
"GREENSBURG, Kan. - Scientists located a rare meteorite in a Kansas wheat field thanks to new ground penetrating radar technology that some day might be used on Mars.
"The dig Monday was likely the most documented excavation yet of a meteorite find, with researchers painstakingly using brushes and hand tools in order to preserve evidence of the impact trail and to date the event of the meteorite strike. Soil samples were also bagged and tagged, and organic material preserved for dating purposes.
"Even before they had the meteorite out of the ground, the scientific experts at the site were able to debunk prevailing wisdom that the spectacular Brenham meteorite fall occurred 20,000 years ago. Its location in the Pleistocene epoch soil layer puts that date closer to 10,000 years ago."

Scientists were also able to see frost, and layered deposits of ice and dirt at the polar ice cap which indicate "dynamic climate changes" as recently as 100,000 years ago, scientist Scott Murchie said.
This latest Mars mission will also determine whether there is enough water on the planet to support a manned mission. "

October 17, 2006.15:51 SPACE: Large Galaxy Caught in the Making
Quote:
"Astronomers have long suspected that most large galaxies form at least in part by acquiring smaller galaxies in dramatic cosmic mergers.
New images from the Hubble Space Telescope support that view.
Hubble photographed the Spiderweb Galaxy [image], officially MRC 1138-262. It is 10.6 billion light-years away. The light we see from it emanated when the universe was only a couple billion years old.
The Spiderweb Galaxy sits amid an emerging galaxy cluster [image], and dozens of young, small, star-forming galaxies are seen merging into the Spiderweb.
"The new Hubble image is the best demonstration so far that large massive galaxies are built up by merging smaller ones," said study leader George Miley from Leiden Observatory in The Netherlands.
October 16, 2006.01:16 FOR REAL: Molecules Manipulated with Lasers
Quote:
"A research team at the National Research Council Canada (Ottawa) has developed a new quantum technology which uses laser pulses to control quantum processes. The method, which is described in the October 13th web release by the world's leading scientific journal, Science, was illustrated by changing the outcome a chemical reaction.
Quantum technologies make use of the molecular scale properties of matter. At this scale, which is different from our everyday world, matter behaves according to the rules of quantum mechanics. Although the rules are well understood, the tools required to control quantum processes are still under development. Quantum technologies aim to manipulate molecular scale behaviour, in a way not usually seen in nature, for fundamentally new applications. For example, methods to implement quantum information/computation (i.e. computers based upon quantum rules) are the subject of an international race to harness the power of this new technology. Another example of quantum technology is the control of chemical reactions using laser light, the example chosen by the NRC researchers to illustrate their new approach.

Quote:
"Mock moon landers are set to compete for millions of dollars in prize money at next week's Wirefly X Prize Cup in Las Cruces, New Mexico, US.
As the US prepares to return humans to the Moon, ambitious young companies are trying to build their own versions of a Moon lander for the Northrop Grumman Lunar Lander Challenge, a NASA-backed contest. It will be one of the headline events at the competition promoting private spaceflight on 20 and 21 October.
There are actually two levels to the competition. In Level 1, the mock landers will launch up to 50 metres high, hover for 90 seconds and then land vertically on a concrete pad 100 metres away.
For Level 2, entrants will launch their rockets, hover for 180 seconds and then land on an uneven simulated Moon surface 100 metres away. For both levels, the rockets can refuel before making the return launch back to the first pad.
Time will present a big challenge. Teams have just two and a half hours to drive from a staging area to the launch pad, pressurise and fuel their vehicles, and complete the challenges.
Up to $2.5 million is up for grabs. The Level 1 winner will win $500,000 and the runner-up will get $150,000. The big money comes with the Level 2 competition. First place gets $1.25 million, second place $500,000 and third place $250,000. "
October 13, 2006.19:14 SPACE: Distant Planet is Half Fire, Half Ice
Quote:
" The poet Robert Frost wondered if Earth would wind up a world of fire or ice. Astronomers have discovered that a distant planet is both.
With one side always hot as lava and the other chilled possibly below freezing, Upsilon Andromeda b is a giant gas planet [image] that orbits extremely close to Upsilon Andromeda, a star 40 light-years from our solar system in the constellation Andromeda.
"If you were moving across the planet from the night side to the day side, the temperature jump would be equivalent to leaping into a volcano," said study leader Brad Hansen of the University of California, Los Angeles.
What's cooking
Researchers think Upsilon Andromeda b is absorbing and then immediately radiating heat from its star [animation], so that one side is always hotter than the other. It's also possible the planet is tidally locked to its star the way the Moon is with Earth, so that one side of the planet always faces-and is always heated by-its star.

October 13, 2006.13:20 FOR REAL: The Universal Translator
Quote:
"One day, a U.S. soldier entering tense situations without the assistance of an Arabic interpreter might rely on two-way translation software in mobile computers.
This year the military's Joint Forces Command has been testing laptops with such software in Iraq. When someone speaks into a microphone attached to the computer, the machine translates it into Arabic and reads that translation aloud over the PC's speakers. The software then translates the Arabic speaker's response and utters it in English.
If the software is uncertain about what one party said, it presents choices on the computer screen for the speaker to choose.
The military has had variations on this. Troops in Afghanistan had a gadget called the Phraselator that could speak a list of commonly useful phrases such as "get out of the car."
But the newer software can facilitate two-way conversations not limited to pre-chosen phrases. Recently the Joint Forces Command began testing one such system, known as IraqComm and produced by SRI International, on about 30 computers. Now the military is announcing a similar experiment is underway with software known as MASTOR from IBM Corp.

"In the 1982 movie "Tron," a programmer goes into a computer world, where he must compete in the gladiator-style games he helped design. For many gamers, possessing the powers, living the life and fighting the battles of their favorite characters would be a dream come true. Virtual reality can make this possible, but it's not the only solution. What if you could build a video-game environment in the real world with a system that would allow you to perform all of the game's actions and moves in real time and space? A team of three New York University students -- Daniel Albritton, Quanya Chen and Noah Shibley -- is doing just that with one of the most popular video games ever produced: "Super Mario Bros." They're calling their creation "Nintendo Amusement Park," and with it, they're helping to evolve a new area of science known as physically-augmented reality. "

Yes. Scientists in the U.S. and the U.K. have made metamaterials with what’s called a negative index of refraction. Generally, these metamaterials are coiled metal wires surrounded by air or another insulator and affect only microwave radiation. Can the cloaking be perfect? Almost. Any metamaterial absorbs a little bit of light and therefore casts a slight shadow. "

Quote:
"Hubble's most frequently used instrument, the Advanced Camera for Surveys (ACS), is partially functioning again, after shutting down unexpectedly on 23 September.
The ACS uses three channels that are essentially three different cameras, and the problem began shortly after Hubble's managers attempted to switch power from the Solar Blind Channel (SBC) to the High Resolution Channel (HRC).
Despite the command to switch, Hubble's computer detected that power was not getting to the HRC and automatically shut down all three channels (see Hubble's key camera shuts down again).
Now, the camera's Wide Field Channel (WFC) has resumed observations, with the other two channels still offline. The WFC, the channel that had been used for most ACS observations, gets its power from an independent route that is not affected by the other two channels.

"IT WAS the perfect quote to match a momentous occasion. As Neil Armstrong became the first man to walk on the Moon in 1969, a global audience of 500 million people on Earth watched and listened with bated breath.
“That’s one small step for man, one giant leap for mankind,” they heard him say as he dropped from the ladder of his spacecraft to make the first human footprint on the lunar surface.
But from the moment he said it, and for 37 years since, debate has raged over whether the Nasa astronaut might have fluffed his lines.
Mr Armstrong has long insisted that he meant to say “one small step for a man . . .” — which would have been a more meaningful and grammatically correct version, free of tautology. But even the astronaut himself could not be sure.
“Damn, I really did it. I blew the first words on the Moon, didn’t I?” he is reported to have asked officials later, amid uncertainty as to whether he had blown the moment or simply been drowned out by static interference as his words were relayed 250,000 miles back to Earth.
