Canada's first space tourist will blast off into space as part of a three-man supply crew on Sept. 30.

Cirque du Soleil founder Guy Laliberté, NASA astronaut Jeff Williams and Russian cosmonaut Maxim Suraev are scheduled to launch on a Russian Soyuz spacecraft from the Baikonur Cosmodrome in Kazakhstan.

"I think this is a great, great opportunity of inspiration and I intend to inspire myself as much as possible," said Laliberté, speaking from the Johnson Space Centre in Houston.

Future Robot Soldiers?

The Exoskeleton: Extreme Technological Innovation -- Raytheon

Raytheon Company’s research facility in Salt Lake City, Utah, is developing a robotic suit for the soldier of tomorrow. The exoskeleton is essentially a wearable robot that amplifies its wearer’s strength, endurance and agility. Reminiscent of super heroes depicted in comic books and Hollywood movies, the bleeding edge technology effectively blurs the lines between science fiction and reality. So much so, that Popular Science magazine recently likened Raytheon’s exoskeleton to the “Iron Man”® depicted in the blockbuster movie of the same name.

From The Philadelphia Inquirer:

Health care as we know it didn't exist 3,000 years ago. But along the Georgia coast, the Pacific Northwest, and coastal Brazil, people grew tall and strong and lived relatively free of disease. They ate game, fish, shellfish, and wild plants.

But as corn farming spread through various regions of the Americas, people got shorter. Many became prone to anemia and began dying of tuberculosis and other infectious diseases.

Rather, the effects have more to do with pockets of carbon dioxide generated when they gather in groups, space station flight controller Heather Rarick said.

Space Mission To Mercury: How An Ion Engine Works

Photo courtesy NASA
This image of a xenon ion engine, photographed through a port of the vacuum chamber where it was being tested at NASA's Jet Propulsion Laboratory, shows the faint blue glow of charged atoms being emitted from the engine. The ion propulsion engine is the first non-chemical propulsion to be used as the primary means of propelling a spacecraft.

From The Telegraph:

The solar electric propulsion systems – or ion engines - which will power the next generation of spacecraft to Mercury and beyond are ten times more efficient than conventional rocket engines.

In an ion engine the gas xenon is pumped through a chamber where xenon atoms are stripped of an electron, becoming electrically charged ions, and drift towards two grids a millimetre apart.

The grids are fed with two thousand volts – in space this power will come from paper-thin solar panels spanning 26m. As the ions pass through the electrified grids they accelerate to up to 50km a second and shoot from the rear in a parallel beam.

Olivas and Stott left the International Space Station at 4:49 p.m. Tuesday, and spent the next 6 hours and 35 minutes outside, working to get cargo that space shuttle Discovery will bring home ready for its return. They started with a depleted ammonia tank assembly on the P1, or port 1, segment of the station’s truss, getting it out of the way in preparation for the installation of a new tank to be installed on Thursday, during the mission’s second spacewalk. The ammonia in the tanks is used to cool the station and expel the heat generated by its residents and systems.

Gene-synthesis industry at odds over how to screen DNA orders.

A standards war is brewing in the gene-synthesis industry. At stake is the way that the industry screens orders for hazardous toxins and genes, such as pieces of deadly viruses and bacteria. Two competing groups of companies are now proposing different sets of screening standards, and the results could be crucial for global biosecurity.

"If you have a company that persists with a lower standard, you can drag the industry down to a lower level," says lawyer Stephen Maurer of the University of California, Berkeley, who is studying how the industry is developing responsible practices.

Global Warming And The Sun -- A Commentary

From L.A. Times:

Recent studies seem to show that there's more to climate change than we know.

Assuming there are no sunspots today, a 96-year record will have been broken: 53 days without any solar blemishes, giant magnetic disruptions on the sun's surface that cause solar flares. That would be the fourth-longest stretch of stellar solar complexion since 1849. Wait, it gets even more exciting.

During what scientist call the Maunder Minimum -- a period of solar inactivity from 1645 to 1715 -- the world experienced the worst of the cold streak dubbed the Little Ice Age. At Christmastime, Londoners ice skated on the Thames, and New Yorkers (then New Amsterdamers) sometimes walked over the Hudson from Manhattan to Staten Island.

Why Pacific Hurricanes Hit The Americas So Rarely

Hurricane Jimena was heading west-northwest toward Mexico’s Baja Peninsula on August 30, 2009, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image.

Astrophysicists Puzzle Over Planet That's Too Close To Its Sun

The planet is known as a "hot Jupiter," a gas giant orbiting the star Wasp-18, about 330 light-years from Earth. The planet, Wasp-18b, is so close to the star that it completes a full orbit (its "year") in less than an Earth day, according to the research, which was published in the journal Nature.

Fahrenheit 747: World’s Biggest Fire Extinguisher Douses L.A. County

The deadly fires that have blackened more than 105,000 acres around Los Angeles prompted authorities to call in the world’s largest fire extinguisher — a Boeing 747 that can drop 20,000 gallons of retardant over a swath of land three miles long.

The plane made its first-ever drop in the continental United States when fire officials summoned it to the Oak Glen fire east of Los Angeles mid day on Monday. After the successful first drop, the Supertanker was called back into action Monday evening where it made further drops on the massive Station fire north of the city which grew to more than 164 square miles and threatened 10,000 homes. Nearly 2,600 firefighters from as far away as Montana are throwing everything they have at the blaze, and on Monday they called in the biggest tool in their inventory.

The consensus among scientists has always been that lower levels of vitamin D at higher latitudes — where the sun is less intense — caused the lightening effect when modern humans, who began darker-skinned, first migrated north.

A MONKEY sits on a bench, wires running from its head and wrist into a small box of electronics. At first the wrist lies limp, but within 10 minutes the monkey begins to flex its muscles and move its hand from side to side. The movements are clumsy, but they are enough to justify a rewarding slug of juice. After all, it shouldn't be able to move its wrist at all.

A nerve connection in the monkey's upper arm had previously been blocked with an anaesthetic that prevented signals travelling from its brain to its wrist, leaving the muscles temporarily paralysed. The monkey was only able to move its arm because the wires and the black box bypassed the broken link.

When California cabernet sauvignon bested the best of Bordeaux--in a legendary blind tasting, the "Judgment of Paris," convened by the English wine merchant Steven ­Spurrier--it was a moment of great national pride at the time of America's Bicentennial, and it was achieved in part because California winemakers had used technology in ways tradition-bound French winemakers would not. As California wine became respectable, Silicon Valley millionaires bought vineyards in Napa and Sonoma counties. California wine and tech soon enjoyed a happy marriage.
