This thread is begging for a "took an arrowa bolt to the comet" joke.
Still, that thing looks awesome thumb.gif I love medieval design.

My only question is what about newton's law? Every force has an equal and opposite force. So if this "digger" is floating and shoots the arrow, would it push its self away? Or would they get super close so that they don't give the opposite force enough time to take hold and shoot the "digger" in a separate direction?

Your survival, and the survival of billions or even trillions of animals, depends on the multitudinous assortment of anaerobic bacteria that live in your gut and help you process food. Anaerobic bacteria are everywhere. Life can live without air.

I would assume it would use a rocket booster to counter the push back.

Scientist 1: Nahhhh, to much work vacuuming space up.
Scientist 2: How about a plunger on a string that sucks up particles?
Scientist 1: Oooo, now you're on to something... I GOT IT!!!
Scientist 2: What is it?
Scientist 1: We build a large crossbow and we shoot it at the comet with a plunger on the end to take samples.
Scientist 2: My god, we're genius.
Scientist 1: Oh yes, we're NASA.

I'm gonna tell you a nice little story I'm sure plenty of people here have heard and draws a few parallels with what you are saying. When the USA first went into space they realized that ball point pens would not work in zero gravity, so the American government spent butt loads of money to develop a pen that could write in space, know what the USSR did? Use Pencils. You don't always need to use the most expensive and intricate design for everything, sometimes the simple route can be the best.
