Transparent aluminum! Would that be worth somethin’ to ya, eh?

It’s hard to say if boffins at Oxford University got their inspiration from Nimoy and Co., but one thing’s for sure: they aren’t joking about the creation of transparent aluminum. In what can only be described as a breakthrough for the ages, a team of mad scientists across the way have created “a completely new state of matter nobody has seen before” by blasting aluminum walls (around one-inch thick) with brief pulses of soft X-ray light, each of which is “more powerful than the output of a power plant that provides electricity to a whole city.” For approximately 40 femtoseconds, an “invisible effect” is seen, giving the gurus hope that their experiment could lead to new studies in exotic states of matter. For a taste of exactly what we mean, feel free to voice command your PC to jump past the break. Or use the keyboard, if you’re feeling quaint.

Scientists Employing Supercomputers for Complex Visuals

Argonne_Supernova_Research.jpg

It may seem that the age of the supercomputer a la Cray-1 has long passed. But that’s not entirely true–we just don’t hear about them as often. For example, scientists at the U.S. Department of Energy’s Argonne National Laboratory are visualizing supernova, protein structures, and other complex phenomena using supercomputers.

The scientists there are using a technique called software-based parallel volume rendering, which interprets the billions of data points collected from MRIs, X-rays, or research simulations. They’re also working on equations that could search for sudden density changes–for example, separating bone from muscle data–in order to generate complex visualizations.

Using parallel computing, such as with Argonne’s Blue Gene/P supercomputer, scientists can create images using the computer’s 160,000 cores. (Try that on a Core i7.) The above image is a rendering of a supernova–specifically, the mechanisms behind a star’s violent collapse, with different colors and transparencies depicting different values of entropy.

Aabar Investments takes 32 percent stake in Virgin Galactic, we’re still not cool enough to go to space

United Arab Emirates company Aabar Investments and today announced that it would be taking a 32 percent stake in Richard Branson’s Virgin Galactic space tourism venture, a deal worth about $280 million dollars. Though the deal has yet to be approved by US regulatory agencies, Aabar, which is an investment vehicle for Abu Dhabi’s government, said that it plans to build a spaceport in the capital city, and that it’s committed an addition $100 million to fund satellite launch capabilites. The deal gives Aabar the regional rights to host tourism as well as scientific research flights. When asked how they felt about having Richard Branson hanging around their city, reps from Aabar said, “King Crazy? We love that guy!”

“Flying laptop” spacecraft could “transform” in space, sort of

Impressive as they are, satellites and space probes aren’t always the most versatile pieces of equipment once they’re up in orbit. A new satellite developed by researchers from the University of Stuttgart’s Institute of Space Systems looks set to shake things up in a pretty big way when it launches in 2012, however, even if it’s not quite the “transforming” space probe that you might be imagining. Described as a “flying laptop,” the satellite promises to pack a vast array of instruments and sensors, including cameras, multispectral imagers, star trackers, and GPS receivers, to name a few, all of which can apparently be completely reconfigured on the fly in space. That, the researchers say, could let the satellite switch from, say, an atmospheric pollution sensor to a near-Earth asteroid detector, an even open up some new commercial possibilities, with different groups able to rent out the satellite to perform various tasks.

A Real Astronaut Reflects on America’s Moon Landings, Past and Future

Our friend and astronaut blogger Leroy Chiao was an invited guest at the Apollo 11 40th Anniversary gala last night. Here he shares a few shots, his memories of the Eagle touchdown, and his thoughts on the next moon mission.

A Spam and peanut butter (chunky) sandwich: That was what I had for lunch, forty years ago, just before watching along with the rest of the world as Eagle touched down on the surface of the Moon.

It was a hot summer day in Danville, California. My family lived in a nice house, in a nice neighborhood. Nevertheless our home, like many built in that era, didn’t have air conditioning. So, my father moved the family TV set (19″ black and white, rabbit ear antennae) out onto the partially shaded back patio. He sprayed water onto the concrete, which helped make it surprisingly cooler.

My friends, two brothers Mike and Russ, were visiting. We had been friends for a long time (two years was long time to an eight year old). So, they had become accustomed to being served odd concoctions at my house, invented by my Dad. Spam and peanut butter sandwiches was one of those. It was surprisingly, not too bad. I had experimented once with a plain Spam sandwich. I quickly went back to including the chunky peanut butter.

I can remember like it was yesterday, watching that grainy black and white TV and listening in as Eagle approached the surface of the Moon and landed. Even as a young boy, I knew that the world had just changed. I also knew that I wanted to be like those guys on the Moon. I wanted to be an astronaut!

Twenty years later, I found myself in Houston, interviewing at NASA to be a member of the thirteenth astronaut group. What a heady time—President Bush (41) had just announced the Space Exploration Initiative (SEI), calling for a return to the Moon to stay, followed by a crewed mission to Mars. And, we had astronauts in key NASA management positions, including the Administrator himself.

SEI fell flat, soon after the President failed to win reelection. The $400 billion price tag quoted by NASA might also have had something to do with it. Fifteen years after the SEI announcement, I found myself standing with a small group of fellow astronauts at NASA Headquarters, as President Bush (43) announced the Vision for Space Exploration (VSE) in the wake of the Space Shuttle Columbia accident. The Vision called for, among other things, a crewed return to the Moon by 2020, and a crewed mission to Mars, on an indefinite schedule.

The Constellation program, which grew out of the VSE, was described by then-NASA Administrator Mike Griffin as “Apollo on Steroids.” Indeed, it called for the creation of a capsule spacecraft (albeit, much larger). Five years into Constellation, the nation stands at a crossroads. The program has had its share of challenges and controversy and the budget is universally agreed to be inadequate. Newly inaugurated President Obama has ordered a review and a report, outlining a set of options for NASA and the agency’s new Administrator. (I am a member of the Review of U.S. Human Space Flight Committee.)

Today, on the 40th anniversary of the Apollo 11 Moon landing, our return to the Moon is tenuous, at best. Who, in 1969, could have imagined that we would not have regular travel to and from Moon bases by the 20th anniversary of Apollo 11? The announcement of the SEI in 1989 gave us hope that we would be back on the Moon to stay, within another twenty years. Those twenty years have now passed.

Tonight, I was an invited guest at the 40th Apollo anniversary celebration at the National Air and Space Museum. Everything was perfect: The Apollo 11 crew—Neil Armstrong, Buzz Aldrin and Michael Collins were elegant and stately against the backdrop of historic air and spacecraft. Other Apollo-era astronauts, like my friend Walt Cunningham, were also shining honorees. They were all a part of it!

It was a reminder of old times, of the past grandeur and wonder of the Apollo era. The time when we, as a nation, felt like nothing was impossible! A time, when Spam and peanut butter (chunky), tasted better than almost anything.

Should we look back at the last forty years and be disappointed? I believe that would be a mistake. Skylab was a resounding success. Despite the challenges, the Space Shuttle and ISS are marvelous flying machines. We started down the road of international cooperation with the Apollo-Soyuz Test Project, and led the formation and maturation of the current, highly successful international partnership. We have not had the big home run since Apollo, but we have made steady progress.

Where will the next twenty years take us? Against all odds, Spam is still going strong. Let’s keep moving forward too.

Leroy Chiao, Ph.D. served as a NASA astronaut from 1990-2005. During his 15-year career, he flew four missions into space, three times on Space Shuttles and once as the copilot of a Russian Soyuz spacecraft to the International Space Station. On that flight, he served as the commander of Expedition 10, a six and a half month mission. Dr. Chiao has performed six spacewalks, in both US and Russian spacesuits, and has logged nearly 230 days in space.

Dr. Chiao is Gizmodo’s official astronaut (and “astroblogger“). On occasion, he still eats Spam and peanut butter (chunky) sandwiches.

Apollo 11 moon mission to be recreated on the web

While the shuttle Endeavour is having a tough time getting off of the launch pad, the Apollo 11 moon mission should proceed as scheduled later this week. Some 40 years after Neil Armstrong and a host of behind-the-scenes workers at NASA made JFK’s vision a reality, WeChooseTheMoon.org is being launched to recreate the whole spectacle. Starting a full 90 minutes prior to the 40th anniversary (that’s 8:02AM on July 16th), the site will be fully operational, tracking the capsule’s route from Earth to the moon. Reportedly, visitors will be able to peek “animated recreations of key events from the four-day mission, including when Apollo 11 first orbits the moon and when the lunar module separates from the command module.” If you’re one of those who remembers “exactly where you were on that fateful day,” you should probably queue up a Google alert and bookmark your browser to relive the whole experience again.

Motorola’s Aura Celestial Edition soon taking “giant leaps” for “mankind”

Here’s a fact: the world really doesn’t need another mildly tweaked Aura. Sorry, it just doesn’t. That being true and all, we’re still pretty jazzed to see Motorola giving the ultra-luxurious handset another go with the moon-themed Celestial Edition. Word on the street has it that this here handset won’t deviate much from the predecessor, but it will come pre-loaded with multimedia from the original moon landing mission, a laser etched quote honoring the 40th anniversary of the journey and a price tag that’s far, far beyond stratospheric. We’re told that it’s all set to go on sale next month, but good luck finding one.

NASA to Unite Lucky 13, Also Build Porch

NASA_Shuttle_Sunrise.jpg
The space shuttle Endeavour is set to blast off Saturday morning at 7:17 a.m. ET, for a 16-day mission to help expand the International Space Station. As CNN reports, when the seven crew members meet up with the six astronauts already on the station, the 13 people will make up the largest space “get-together” yet.
In addition, with Endeavor’s launch, a total of 500 people will have now traveled into space, the report said. The blast-off will also be the first time two Canadians–Julie Payette and Robert Thirsk–will be in space at the same time.
The mission’s main purpose is to install a porch. Well, not exactly–the crew will install two platforms for the Japanese Kibo Laboratory, which is already part of the station, the report said. One platform will ride up and down to the shuttle, while the other will stay fixed to the lab for experiments out in open space. During the mission, the crews will have to be extra careful (as if they weren’t already), due to the busier-than-usual communication channels during the shuttle’s five spacewalks.

Earth and Venus Could Smash Together–In 3.5 Billion Years

Earth_Venus_Collide_BBC.jpg

According to a study released Wednesday in Nature, a force known as orbital chaos could “cause our Solar System to go haywire,” leading Earth to smash into Venus or possibly Mars, the AFP reports. Most likely, the sun and solar system will continue on for another five billion years. At that point, the sun will become a red giant and engulf the inner planets (Mercury, Venus, Earth, and Mars).

But it turns out that we can’t predict the course of celestial mechanics–the motion of our planets–more than a few tens of millions of years into the future, said Jacques Laskar, a researcher at the Observatoire de Paris and lead author of the study, in the report. That led to some fancy computer modeling using Einstein’s theory of general relativity, which hadn’t been done before.
Laskar’s group ran over 2,700 computer simulations. They found that over 200 of them caused the four inner planets and the sun to be in a five-way accident, with Earth “being smashed to pieces” in several dozen of them a few billion years from now. The likely culprit? Mercury, which has a lopsided orbit and the smallest mass–meaning that it could (eventually) be easily destabilized, causing a chain reaction.

Could Astronomers Have Found the First Exoplanet in Another Galaxy?

NASA_Andromeda_Galaxy_M31.jpg

To date, scientists have discovered over 300 exoplanets, which are planets orbiting stars other than our own sun. Recently, a group of astronomers may have detected another one, as Universe Today reports. In and of itself, that’s not news–except that this one may be in another galaxy.

It turns out that one specific star in the Andromeda Galaxy–which is over two million light-years away–has some kind of object orbiting it that’s about six times the mass of Jupiter. At that size and distance, it could be either a planet or a brown dwarf star, but astronomers are leaning toward the former.
To find the exoplanet, the report said that the astronomers used a technique called pixel-lensing, which is essentially gravitational microlensing: looking for bent light rays when they pass close to a massive object, as per Einstein’s general theory of relativity. (Image credit: NASA/Tony Hallas)
