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."
It’s the end of an era, sort of: Fraunhofer IIS, the developers of the MP3 audio compression format, announced that they are ceasing their licensing program. In a blog post, spokesman Matthias Rose says that it’s had a good 20-year run and is obsolete. But it’s also true that the decoding patents expired last year, […]
Freddy deBoer writes that he’s been telling the same joke for years about Silicon Valley’s only product, which might be universalized as “At last, a way to verb with nouns on the internet!” But the social-media techopoly is stable, now, and so the venture capitalists have moved on to the three terrible trends that will […]

Learning to code is a perfect way to grow your technical sophistication, and open up a host of new career options. But since most “learn to code” initiatives focus heavily on web development, it can be tough to find good resources for general-purpose computer science outside of a 4-year degree program. To get a broad […]
