Most CubeSats weigh less than a bowling ball, and some are small enough to hold in your hand. However, the impact these instruments have on space exploration is gigantic. CubeSats — miniature, agile, and cheap satellites — are revolutionizing how scientists study the cosmos.
A standard-size CubeSat is tiny, about 4 pounds (roughly 2 kilograms). Some are larger, maybe four times the standard size, but others are no more than a pound.
