Fun and Interesting Facts About Space Travel

Ever wondered what crying in space is like?

Astronauts can cry, but their tears don’t fall.

With no gravity, tears form floating blobs that cling to the eyes, making it hard to see.

They have to wipe them away manually or let them float off.

Emotional moments in space?

Definitely messier than on Earth.

Space actually makes you taller—temporarily.

Without gravity compressing your spine, astronauts can grow up to 2 inches taller in orbit.

But don’t get too excited; the effect reverses once they return to Earth.

Still, it’s a strange perk of zero gravity that makes space travel a literal stretch for the human

body.

Space smells weird.

Astronauts report that after a spacewalk, their suits and gear smell like seared steak or welding fumes.

The scent comes from high-energy particles interacting with the airlock.

It’s not something you’d bottle as perfume, but it’s a reminder that space is as alien to our

senses as it is to our physics.

You can’t burp in space—at least not the way you do on Earth.

In microgravity, gas doesn’t separate from liquids in your stomach, so a burp might come with a surprise

splash of stomach contents.

Astronauts have to be careful with their digestion, making space travel a bit less glamorous than sci-fi movies

suggest.
