Tractor beams -- the ability to trap and move objects using laser light -- are the stuff of science fiction, but a team of NASA scientists has won funding to study the concept for remotely capturing planetary or atmospheric particles and delivering them to a robotic rover or orbiting spacecraft for analysis. This animation shows how a hypothetical future mission might eventually employ tractor beam technology.

  • I have no literally idea of the physics involved in this video.

    Does anyone?

    Or is this just some "oh wouldn't it be cool if magic existed" bullshit.

    I mean a laser beam attracting particles towards it? oh sure we learned all about that in school.

    WHAT

  • @nte604 so go to space

  • Looks more like the excursion funnel from Portal 2. Also, I guess I was watching too many sci-fi movies, I was expecting it to pull the comet off course or something.

  • It would be nice to get this on my Iphone so I don't have to move to get the paper. Then I can kill the dog.

  • In space, no one can hear you scream.

  • @Jango370 It wasn't hazy like a dream, everything was as clear as it is right now, as I'm commenting on this page
