Astronomers have detected water on the Moon. While that might sound familiar, previous reports were based on spectral signatures that could have been other compounds – this time, the detection is unambiguously water, in the molecular form we need.

Seattle-based USNC-Tech has developed a concept for a safer and more reliable Nuclear Thermal Propulsion system that could help realize the goal reducing Earth-Mars travel time to just three months.

Images returned by NASA's OSIRIS-REx asteroid explorer have confirmed that the spacecraft's sample collector head is slowly leaking some of the material it gathered from the surface of the asteroid Bennu, but it's not all bad news.

A new study has identified 1,004 stars from which aliens could detect signs of life in Earth’s atmosphere by watching as our planet passes across the disk of the Sun. The study could help provide targets for groups searching for alien civilizations.

On Tuesday this week, NASA’s OSIRIS-REx spacecraft briefly touched down on the surface of asteroid Bennu to snatch a sample of the ancient pristine rock, and took off again. And now NASA has released images and video from the robot’s perspective.

In a truly remarkable feat of engineering, NASA’s OSIRIS-REx spacecraft has scooped a sample of soil from the surface of asteroid Bennu, as it hurtles through space some 205 million miles from Earth.

NASA’s plans to return to the Moon involve building the infrastructure to support a long-term lunar base. As part of this vision, the agency has selected Nokia to help it build the first ever cellular network on the natural satellite.

Four-wheeled robotic rovers may be a good choice for the exploration of other planets, but they could conceivably get stuck at the bottom of deep craters. NASA's DuAxel rover is designed with that in mind, as it splits in two for steep descents.

The star Betelgeuse has dimmed twice in the past year. Now astronomers say they’ve found what may have caused the latest episode – and also discovered that the star is smaller, closer to Earth and further from exploding than previously thought.

ESA has awarded Airbus a €491 million contract to design and build the Earth Return Orbiter, which will return the first samples collected from the Red Planet by NASA's Perseverance rover to Earth.

The joint ESA-JAXA BepiColombo probe has successfully completed the first of two scheduled flybys of Venus, gathering data about the planet's dense carbon dioxide atmosphere as it came to within 10,720 km its surface.

It has been revealed today that planetary scientist Alan Stern will be among the first humans to be carried into space by Virgin Galactic's spaceplane, where he’ll take a hands-on approach to a pair of high-altitude experiments.
