NASA researchers are exploring the possibility of tractor beams. The scientists are studying several methods for grabbing planetary or atmospheric particles in a laser beam for transfer to an instrument that would analyze their composition.
"The original thought was that we could use tractor beams for cleaning up orbital debris," (principal investigator Paul) Stysley said. "But to pull something that huge would be almost impossible -- at least now." That's probably ok because the old man would get that tractor beam out of commission anyway. From NASA:
Currently, NASA uses a variety of techniques to collect extraterrestrial samples. With Stardust, a space probe launched in 1999, the Agency used aerogel to gather samples as it flew through the coma of comet Wild 2. A capsule returned the samples in 2006. NASA's next rover to Mars, Curiosity, will drill and scoop samples from the Martian surface and then carry out detailed analyses of the materials with one of the rover's many onboard instruments, including the Goddard-built Sample Analysis at Mars instrument suite.
"These techniques have proven to be largely successful, but they are limited by high costs and limited range and sample rate," Stysley said. "An optical–trapping system, on the other hand, could grab desired molecules from the upper atmosphere on an orbiting spacecraft or trap them from the ground or lower atmosphere from a lander. In other words, they could continuously and remotely capture particles over a longer period of time, which would enhance science goals and reduce mission risk."

Neglected public payphones in New York City are being turned into “GuyFi” stations: a place where one can rub one out for the sake of “stress relief.” Annalee Newitz reports on the wank booths from a company named “Hot Octopus”… The company reported that at least 100 men used the booth on its opening day […]
You’d be forgiven for thinking the videocassette format long-dead, but it turns out that Betamax is still around. Sony is finally going to withdraw tapes from sale, bringing a 40-year story to an end. The last recorders were sold in 2002. ベータビデオカセットおよびマイクロMVカセットテープ出荷終了のお知らせ [Sony; via The Verge]
If you’ve been blessed enough to avoid them yourself, you’ve definitely heard the horror stories. Late night, crushing out a ton of work, writing, coding, anything, then boom – your computer crashes. The battery blows, you spill water or coffee all over the place, or it just shuts down with no explanation, and you’re screwed. […]
You travel around a lot. It might be that jet set life from New York to LA to London to Tokyo, or it might be back and forth from the coffee shop to the office, or from the kitchen to the couch. Any which way, you’re mobile and that’s the way to live. When you […]
It’s 2016 and we like our technology really small. Our phones fit in our pockets, our remotes are lighter than ever, and even our cars seem to be shrinking. So your new drone shouldn’t be an exception. This Axis VIDIUS Drone is 21% off right now and it’s so little, your biggest problem won’t be […]
