Thanks to not-so-recent advances in technology, we can shoot just about anything into space, or at the very least into Earth's orbit. At first, we launched spy satellites during the Cold War, but once ...

Digestive gas gets the best of everyone sooner or later, often in the form of a burp. Burping is how the body clears excess gas from the upper digestive tract, which would otherwise result in ...

Living in space isn’t just about floating in zero gravity or gazing at Earth from above. It’s about adapting to a world where even the most basic human actions - like crying or sneezing - don’t work ...

Space travel is heating up, both by NASA and private enterprises, with bold adventurers and scientists looking to eventually send humans to Mars. One of the challenges of such a multiyear mission in ...

As my arms lift from my sides, and the rest of my body follows suit toward the ceiling of a modified Boeing 727—next to scientists, astronauts, engineers and activists—I think, “How did I get here?” I ...

As plans for missions to Mars accelerate, so do questions about how the human body might cope. A return trip to the red planet would give more than enough time for someone to become pregnant and even ...

I mostly keep all four paws on the ground. It’s hard to imagine living out in space. I asked my friend Erica Crespi about it. She’s a biologist at Washington State University. She studies how animals ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Blue Origin will launch its first suborbital rocket launch of 2025 today — and attempt a wild spin trick to mimic the moon's gravity during the flight — but if you want to see it live, you'll need to ...
