“Space” is such a big idea, it can seem like a big mystery. We want you to feel how amazing space is, and also to imagine yourself working there. Maybe you will be the first woman to walk on Mars, or will start a private space exploration company!
Why does the Racing Gravity Experiment work that way? What is gravity?
Imagine you’re standing on a ladder and your friend is a few rungs down, holding onto your ankles. If your friend is very strong, you’ll find it very hard to move. If your friend lets go altogether, you can climb right up the ladder.
Gravity works the same way: it’s the force that keeps you from floating up. In fact, people DO exert a gravitational pull on each other. However, because our bodies are tiny compared to the Earth, the pull is not very strong.
Why do you weigh differently on different planets?
Mass measures how much matter an object contains. Weight measures the pull of gravity on that object. When you travel to a different planet, your mass doesn't change, but your weight does.
The moon has a weaker gravity than Earth, so when you try to walk there, you bounce. You can’t walk on the sun, but if you could, the sun’s powerful gravity would cause you to sink into the surface. If you weigh 100 pounds on Earth, then if you became the first person to walk on Mars, you would weigh only 37.7 pounds! Calculate your own weight here.
Did you know that you are made out of stars?
It's true! Almost every element in your body (and on earth) comes from stardust – tiny pieces of stars that exploded eons ago. The sun is one of at least 100 billion stars – and that’s just in our galaxy, the Milky Way. If you were traveling at the speed of light(186,000 miles per second), it would still take you 100,000 years to get across the Milky Way. That's a lot of space, and a lot of stars! How many stars, do you ask? There are more stars in the sky than there are grains of sand on all of Earth’s beaches.
When something breaks in space, who fixes it?
Astronauts who live on the International Space Station can’t go outside without special equipment, but we can design robots to go just about anywhere: into outer space, into disaster zones, down to the bottom of the ocean, even inside human bodies.

TAME's traveling Trailblazers are one-of-a-kind science museums-on-wheels. Exciting, hands-on exhibits teach students about energy, space, weather, biotechnology, and aerodynamics while also introducing them to educational and career opportunities in STEM. Check out what else you can learn from taking a peek inside the Trailblazer's Space area.

If you could do one thing to make life on Earth better, what would that thing be? Here's a Grand Challenge: according to some of the world's smartest people, this is a challenge that humans will face in the next 100 years. What would you do to help solve it?
How can we explore new planets, or find out what lives in the deepest parts of the Earth’s oceans? What will it take to sustain human life on another planet? Can you help develop new vehicles or invent tools for exploration?
Pollution is changing the planet -- and the way that we humans live. Can you help find ways to contain carbon dioxide emissions? Can they be contained underground or in the ocean?
