Physics Basic Astronaut for Kids: Rockets Orbits Gravity Zero-G and Space Exploration Explained for Young Scientists Ages 8-12: 19 (Physics Kids Books) - Tapa blanda

Sinopsis

What does it actually feel like to fall around Earth at 28,000 kilometers per hour — and why don't astronauts crash?

This chapter-by-chapter guide walks young readers through the real physics that launches rockets, keeps astronauts alive in orbit, and will one day send humans to Mars. No dumbing it down — just clear, engaging explanations that make the science click.

Inside each chapter, readers will discover:

• How controlled explosions and Newton's Third Law push a rocket off the launchpad and past escape velocity
• Why orbiting astronauts are actually in a constant free fall — and why they never hit the ground
• What microgravity does to bones, muscles, and the human heart over weeks in space
• How a spacesuit engineers survival across a 280-degree temperature swing during a spacewalk
• Why crumbs are dangerous, water floats in spheres, and every push sends you drifting in zero gravity
• How heat shields ablate at 1,600°C to bring a spacecraft safely through re-entry
• Why speeding up in orbit makes you go higher — the counterintuitive world of orbital mechanics
• What cosmic radiation does to DNA far beyond Earth's protective magnetic field
• The seven-month physics and biology challenge standing between humans and Mars
• How spinning a spacecraft creates artificial gravity using centripetal force

• Curious readers ages 8–12 ready for real science explained clearly
• Parents and educators looking for STEM-aligned nonfiction with genuine depth
• Homeschool families covering space science, forces, or motion units
• A thoughtful gift for any young reader fascinated by space and how things work
