Could a T. rex Survive on Mars?: And 7 More Wild Questions About Living in Space

An eight-ton dinosaur. An empty planet. One honest question.A T. rex could not survive on Mars. But finding out why-exactly, in order, with real numbers-turns out to be one of the best science lessons a curious kid can get.It would need a pressure suit within a minute. Its bird-like lungs, genuinely better than yours, would not help at all. And after years out there its own skeleton would quietly rebuild itself into something beautifully suited to Mars - and useless back home.This book takes one outrageous idea and answers it properly, eight times over - with the actual engineering, the actual numbers, and the parts scientists still argue about. Inside: - Why a machine the size of a toaster already made oxygen on Mars - and why that still is not nearly enough - The energy pyramid that makes feeding a predator on another planet almost impossible - Why every real Mars base would be buried underground, not built as a glass dome - The first vertebrates ever born in space (they are fish, and it happened in 1994) - Why nothing that stays on Mars long enough can ever safely come home Written for kids who would rather be told the truthEvery chapter ends the same honest way: one box for what scientists can already do, and one box for the thing nobody has solved. No two chapters have the same verdict. Where researchers genuinely disagree, this book says so instead of picking whichever answer sounds tidier.There are eight pages to draw on, a glossary, a list of real published sources any teacher can check, and a "go and see it yourself" section that sends readers outside to find Mars with their own eyes.And on the final page, the twist: every single problem the dinosaur ran into is waiting for the reader too.Ages 8-12. 80 pages. Black and white throughout.
