A launch vehicle’s ascent battles gravity to gain orbital velocity, while re-entry is a controlled struggle against the atmosphere to systematically shed that immense kinetic energy through ...

As more companies take to Low Earth Orbit, this is emerging as a new need. See how microgravity is helping unlock breakthroughs for science too.

A cluster of recent theoretical papers has laid out mathematical frameworks for propelling spacecraft at speeds ranging from ...

The Artemis 2 team successfully completed a critical wet dress rehearsal, marking a major milestone by safely fueling the Space Launch System rocket.

The Moon is slowly shrinking as its interior cools, and that contraction is generating faults and seismic activity in the very region where NASA plans to land astronauts. A study published in The ...

The big picture: In deep-space travel, the race is no longer about who has the biggest rocket – it's about who can build the smartest plasma engine. As the competition to reach Mars intensifies, ...

Being more efficient and more powerful than chemical rockets, plasma engines are seen as the future of human spaceflight. While NASA-backed plasma rocket projects aim for travel times to Mars be just ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear ...

Spacecrafts don’t just rely on rockets—they use planets to pick up speed! Spacecrafts don’t just rely on rockets—they use planets to pick up speed! It’s called a gravity assist, and it’s one of the ...

Here’s what you’ll learn when you read this story: Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation ...
