Learn how astronauts are safeguarded from hazardous space debris through innovative engineering and international ...

The idea that Mars could affect Earth’s climate sounds dramatic, since climate change is usually linked to cars, factories, ...

On average, Martian time ticks roughly 477 millionths of a second faster than terrestrial clocks per Earth day. But the Red ...

Isaac Newton did not just invent calculus and rewrite physics, he also tried to calculate the end of the world with the same ...

It’s possible to defy gravity using sound waves, magnets or electricity, but today’s methods can’t hoist heavy items high in ...

Airlines rarely announce how much water they carry; excess potable water adds weight, but little water is no good either.

Even the best telescopes can’t see exoplanets. It’s all about watching for jiggly stars, blue shifts, and transits.

Even worse, the orbit of Mars is elliptical (think of a slight oval rather than a perfect circle), which means that sometimes ...

Clocks on Mars tick faster by about 477 microseconds each Earth day, a new study suggests. This difference is significantly ...

New measurements using gravitational lensing suggest the universe’s current expansion rate does not agree with signals from ...

Time moves differently on Mars. NIST physicts recently calculated exactly how fast each second passes on Mars. And if humans want to explore the solar system, every microsecond counts.

You may have heard people say that aboard the International Space Station (ISS) there's "zero gravity," but in fact, gravity is still very much present. The station orbits Earth at an altitude of ...
