NASA is testing a new harpoon to collect surface samples off asteroids and comets that were once unreachable.

"The best way to grab a sample of a rotating comet that is racing through the inner solar system at up to 150,000 miles per hour while spewing chunks of ice, rock and dust may be to avoid the risky business of landing on it," NASA said in a statement.

So instead of trying to put humans on any flying space rocks, this device could be used.
