So with the use of a couple different missions I've taken an asteroid from the orbit of the sun; entered it into an LKO on an equatorial orbit; its not a perfect orbit but it'll do for easy return missions. My next Idea is to use a ship/claw with a crap ton of parachutes and land it on Kerbin; possibly near the Launch Pad. Any Suggestions? The asteroid weighs in at 39.65 tons. How many parachutes do you think I'll need?
