NASA is developing a harpoon capable of taking model from comets. NASA said that the samples could divulge the genesis of the planets and how life was shaped on Earth. Comets are made up of frozen chunks of ice, gas and dust. They orbit the sun and, if they are secure adequate to the star, mission a tail in the reverse bearing made up of ionized gases.
The stoop is made out of a pair of spring usually used to grant the postponement for trucks. The bow string is ready out of steel cable half an inch thick.

It can fire projectiles at speeds of more than 100ft per instant. Test projectiles are burning into huge drums full with sand, rock salt, ice or stones. It can fire projectiles at speeds of more than 100ft per second. Inspection projectiles are fired up into large drums filled with rub down, shock salt, ice or .shingle
