Measuring moon dust to fight air pollution

Moon dust, or regolith, isn't like the particles on Earth that collect on bookshelves or tabletops—it's abrasive and it clings to everything. Throughout NASA's Apollo missions to the moon, regolith posed a challenge to ...

Reinventing the clock: NASA's new tech for space timekeeping

Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for example, relies on precise ...

There could be a way to fix spacecraft at L2, like Webb and Gaia

Billions of dollars of observatory spacecraft orbit around Earth or in the same orbit as our planet. When something wears out or goes wrong, it would be good to be able to fix those missions "in situ." So far, only the Hubble ...

Spacewalk an 'emotional experience' for private astronauts

The commander of the daring space voyage that included the first-ever spacewalk by private astronauts described opening the hatch into the void as an "emotional experience" that left him in awe, yet deeply aware of the dangers.

New video shows how tiny spacecraft will 'swarm' Proxima Centauri

Earlier this year, NASA selected a rather interesting proposal for Phase I development as part of their NASA Innovative Advanced Concepts (NIAC) program. It's known as Swarming Proxima Centauri, a collaborative effort between ...

NASA's Artemis II crew uses Iceland terrain for lunar training

Black and gray sediment stretches as far as the eye can see. Boulders sit on top of ground devoid of vegetation. Humans appear almost miniature in scale against a swath of shadowy mountains. At first glance, it seems a perfect ...

Polaris Dawn brings new areas of research, medical care

The launch of Polaris Dawn from Kennedy Space Center includes the first civilian commercial spacewalk and other factors that will be firsts for space medicine research. And that's why Emmanuel Urquieta, an internationally ...

Boeing 'ran out of time' on Starliner: astronaut stuck on ISS

A US astronaut stuck on the International Space Station said Friday he believed Boeing's Starliner could have carried him home, if more time had been available to work through the beleaguered spacecraft's issues.
