For many, the word "apprentice" brings to mind the whimsical scene from Disney's Fantasia where Mickey Mouse, the poor peon to the sorcerer, creates a mess of his master's workspace when the brooms and buckets come to life in a magical musical number. The helicopter apprenticeship at Stanford University seems to contain some of the same elements of unrealism, as helicopters learn to fly and execute complex airborne tricks without a human pilot in the cockpit. In this case, however, there is science behind the magic.

It's becoming a familiar story: robots on the surface of Mars outlasting their expected lifespan. Take the Mars Exploration Rovers Spirit and Opportunity, for example. The rovers landed on Mars in 2004 and have performed so well that NASA has extended their mission activities five times in the past three years.

“Design for extreme environments” sounds like a new cable show, but it’s actually a class at RISD that focuses on building habitats for truly challenging locations—like the moon. Last fall, NASA asked the students to design a mobile dwelling for its next manned mission to the moon, scheduled for 2020. “NASA wanted a rover that could house four people for two weeks in 24-hour sunlight,” says student Zack Kamen.

The Department of Defense (DOD) has a lot to learn about concussions. The National Football League can empathize. For decades the NFL has faced similar questions on prevention, diagnosis, treatment and long term effects. With a concussion occurring approximately every other game, research efforts benefit from an ample and growing population. Recognizing the value in such uniquely willing lab rats, the DOD hopes to steal a few ideas from the league’s playbook.

Pick up your dirty laundry; the European Space Agency is planning to launch most sophisticated explorer satellite in history and it's looking at you. Okay, not exactly. But the launching GOCE (Gravity field and steady-state Ocean Circulation Explorer) will be looking at the Earth more closely than any technology has previously. On Wednesday, September 10th the European Space Agency is launching the sat from an aeronautics station in northern Russia. GOCE will piggyback on a Russian rocket and be released 160 miles from Earth, a relatively low altitude when it comes to space exploration, but nevertheless impressive considering the spacecraft weighs one ton. Once released from the rocket launcher, GOCE—which looks like a five-meter long white Lego piece, flat on either side with a capsule running the length of the middle—will synchronize itself in orbit with the sun and get to work.

If you started just before the first dinosaurs appeared, you’d probably be finishing your hike just about now.

August 15, 2008— The first time Army Specialist Frederick Hussey “got blown up in Iraq,” as he says, was on Easter Sunday, April 16, 2006. Hussey was five months into his yearlong deployment as an infantry medic when a cluster of anti-tank explosives jolted his Humvee off the road some 50 miles south of Baghdad. The blast filled the cabin with acrid black smoke, but Hussey was able to jerk the wheel back and steer the truck to safety. “Everybody ended up being OK with that one,” Hussey says. “You know—shook up and all, but there was no loss of life.

As the actual ground combat between Russia and the former Soviet Republic of Georgia grinds to a halt, security and Web experts have begun to focus on what might have been a secret third front in the conflict: the Internet. With numerous Georgian government Web sites defaced or shut down, the virtual attacks that preceded the actual invasion may go down in history as the first war in cyberspace.

The September Popular Science feature "Shock to the System" (on newsstands next week), discusses the hidden danger of brain trauma faced by soldiers exposed to bomb blasts. The article reveals that one in five American soldiers serving in Iraq may be suffering from a brain injury—not from direct contact with explosions, but from the effects of bomb blast waves that can cause life-threatening damage at the cellular level, even from distances previously considered safe.

A new simulation has mapped out the way dark matter—the invisible heft of the universe—could be distributed in a galaxy like our own Milky Way; showing that dark matter could be much more present in our neighborhood than previously thought, and suggesting that we may soon be able to detect it (and understand it) close to home.

In 1959, William Bertelsen became the unlikely star of a national science magazine.

He wasn't a scientist. He was the country doctor of Neponset, Ill., his hometown of 500 people; he was married, with three girls and one boy. In all his days at school, he hadn't taken a single class in aerodynamics, and only took one course in physics.

Then, at 38, his career in cooking up futuristic, unorthodox vehicles began.

Today marked the public debut of the Martin Jetpack, a ducted-fan-equipped personal flying vehicle that could keep pilots aloft for 30 minutes or more. Inventor Glenn Martin has been working on the jetpack—which isn't technically a "jet" pack, given the fans—for 27 years, but he has kept it secret until now. Even his son, Harrison, the 16-year-old test pilot, wasn't allowed to tell his friends that he'd been cruising around the yard back home in Christchurch, New Zealand in a revolutionary flying vehicle.
