NASA is investigating laser based tractor beam technology.
NASA is now funding a study to investigate if tractor beam technology can be used to gather samples on future space missions. I have always loved the Sci-fi genre but i have newer believed i would have a chance to see all the things being reality. It was always just fantasy i thought. It seems i was wrong. I'm pretty sure i will see stuff in my life i didn't even have read about in Sci-fi books. What an exiting time we live in.
