What time is it in space?
Here on earth we know it's time for breakfast when the sun comes up, but what does that mean on the International Space Station where astronauts get to see a sunrise every hour and a half? We either have to find solution to this problem… or ship up a bunch of milk and cereal!

How do you go to the bathroom in space?
You asked! In fact, you've asked this question, perhaps, more than any other!
Your toilet uses water and gravity, but in space, things are a bit different. Just think "suction" - and watch this!

How can you gross-out your friends with a spacesuit?
You're floating around the space station (OK, maybe you're just walking around the house) in your spacesuit, and you have a spare moment. You say to yourself "Self, how can I gross out my little brother with this cool space garb?" The suit has ball bearings that may come in handy! Try this!

Why do astronauts practice underwater?
Marco… Polo… You can rest assured that astronauts are not playing around when they’re training in NASA’s Neutral Buoyancy Laboratory. Don’t be a fish out of water, come in and see why astronauts become human submarines.

What does the vacuum of space look like?
Gravity still exists in Earth-orbit, but things act a lot differently when in a constant free-fall, rather than feeling wind resistance and hitting the ground. Using a vacuumed air chamber on Earth will help you see what gravity is like in space. Drop everything and check out this brain bite to learn about the difference in gravity from Earth to orbit!

Should you pull over when an astronaut floats by?
An astronaut's space suit is designed a lot like a medical ambulance. But don't worry, the next astronaut to see is probably in perfect health, and their spacesuits help them stay that way!

Would you hear a space ship fly by?
You're at the movies and hear the rumble of the spaceship as it zooms by. Cool!...but what would you REALLY hear? This one's like that bad dream where you scream for help and no one can hear you ... OK, maybe that's just me. Listen closely so you don't miss the silence.
