Travel back in time and into the not-so-distant future to dissect, explore, and discover how all kinds of things do what they do! Along the way, you'll learn why cotton candy is so fluffy, how scientists built a space suit for Mars, and what goes into animating your favorite cartoons.

Look inside, take it apart, turn it over, and figure out how things work! Quippy descriptions, full-color diagrams, and brilliant photographs make even the most intimidating subjects completely accessible--and totally fun! (We're looking at you, space robots.) For every explanation, we touch on basic principles and then dive deeper. Just want to know what terraforming is? We've got you covered. Want to know how to terraform, say, Mars? We'll explain that, too.

But this book isn't just for explaining things. We'll also introduce you to the dreamers, scientists, and innovators who create this amazing stuff. You'll meet a NASA engineer, an underwater archaeologist, and a chocolate scientist. You'll learn what it's like to fly a plane into the eye of a hurricane--on purpose.

Following on the success of National Geographic's How Things Work and How Things Work: Inside Out, How Things Work: Then and Now tackles a whole new batch of extraordinary and everyday things--from man-made to natural, historic to futuristic.

    or you can try watching amazon How It Works. and the ISS can support 50 people at a time! but it would be crowded. and the moon could probably hold about 509,298 people but it would become as polluted as earth with all those moon buggys and/or cars. unless people decided to FINALLY start using electric cars more in stead of fossil fuels.
