NASA's Dragonfly Rotorcraft to Explore Saturn's Giant Moon Titan
University of Florida scientists used lunar soil collected during Apollo 11, 12 and 17 missions to successfully grow plants from seed. It's a first in human history and could help future space colonists grow food on the moon.
Soon, one out of every 15 points of light in the night sky will actually be a satellite, not a star.
If our living space is to become outer space, we have a lot of challenges to address. And our first line of defense will be space architects.

Amazon CEO Jeff Bezos and his brother plan to blast into space next month. But even if you're not related to a billionaire, you can still experience the fun of space at a 'down-to-Earth' price.
Other companies, like Amazon and Telesat, are planning to emulate StarLink's model, meaning there could soon be as many as 50,000 satellites, mostly for the purpose of internet service, floating around in space.
A Russian cosmonaut printed some steak in space, and now we're one step closer to sending humans to Mars.
The moon's getting a new, space-proof library that will serve as an archive for all humanity.
By studying these geological formations here on Earth, we may be able to learn how to live on other planets.
Cosmic radiation gave the fictional Fantastic Four superpowers, but in real life it could destroy an astronaut's mind, a new study shows. NASA's already on the defense.
In the HI-SEAS project, scientists lived together in cramped isolation on Hawaii, simulating the kind of challenges that would bedevil interplanetary explorers
Researchers looked at the sea urchin jaw's uniquely powerful structure to build a better excavation tool, with the aim of digging on Mars — or beyond.
Scientists have discovered how to produce strings of extremely tiny diamonds. The super-strong material could help build a 12.5-mile high elevator into space.
Asteroid-mining startup Planetary Resources has already launched its first experimental probe, and could revolutionize space exploration and exploitation.
Radiation is a serious occupational risk for astronauts. An active shielding approach currently being developed for spacecraft could greatly diminish that risk.
