So, enter the tractor beam. ... In that chamber, they can put their idea to work by shooting small blocks representing space debris with beams of electrons.

One day, small spacecraft could fly around Earth, using devices called electron beams to remove hulking, derelict spacecraft from orbit without ever having to touch. It may sound like science fiction, ...

Human technology is crossing another threshold. Tractor beams have been common in science fiction for decades. Now a team of researchers is working on a real-life tractor beam that could help us with ...

The idea of a solar beam that transmits energy from space to Earth was first proposed in 1968 by Peter Glaser, an engineer working with NASA during the Apollo era. At the time, it was considered ...

A private lunar lander, Athena, has sent back breathtaking images of Earth from space, capturing a unique view of our planet shortly after its launch. Built by Intuitive Machines, the lander ...

Is the Sacramento Kings’ beam visible from space? It’s possible. “Theoretically, the beam can be seen from space ... but it’s complex,” said Suk, an architectural lighting expert.

Solar farms in space could harness the power of the sun, unaffected by bad weather, cloud cover, nighttime or the seasons. ... The beam won’t be powerful enough to be weaponized, he added.

Even by the standards of the Space Race, the idea seemed bold, maybe a bit crazy. In 1968, before the first human set foot on the moon, an engineer working on one of the Apollo mission’s ...

In space, as one Caltech researcher put it, it’s “always noon on a sunny day.”. The basic idea isn’t new—space-based solar power was mentioned in a sci-fi story in 1941, and NASA began ...
