First flown on the space shuttle in 1981, M&M's® chocolate candies have been a staple ever since. Also known as "candy coated chocolates" in NASA jargon (NASA does not endorse commercial products), these sweets have flown in space more than 130 times. Noted for their ability to stay in one piece in very extreme conditions, they have been a favorite for acrobatic micro-gravity dining feats.🍬
