While many missions aim to explore permanently shadowed regions on the moon for water ice, it must be asked how realistic it is to expect to find enough ice on the moon to support human habitation.

While ChatGPT + AI is a powerful tool that can augment new discoveries, it can't yet replace the human-driven process of synthesizing new information to generate new insights into science.

Astronomers are becoming increasingly concerned of being blinded by the light from an estimated 400,000 satellites planned for low Earth orbit in the coming years.

Researchers are working to determine where and at what depths extractable ice exists on Mars. Such deposits could allow humanity to get a foothold on the Red Planet.

Meet Anastasia Stepanova, a PhD student in space resources and a veteran of multiple missions here on Earth that simulate the conditions human crews would experience spaceflight.

Work is now underway to shape a new Mars helicopter design following the groundbreaking flights of NASA's robotic Ingenuity rotorcraft.

Scientists and space agencies are working to develop ways to mitigate the microgravity-induced changes to the human eye that astronauts experience while in space.

The Mars Sample Return mission is an ambitious endeavor that could see Martian geological specimens returned to Earth to search for signs of life on the Red Planet.

The object blasted out of the sky over the Yukon on Feb. 11 may have been an amateur radio pico balloon — specifically, a 33-inch-wide one called K9YO-15.

What do these sky-high visitations mean, if anything, to the UFO/UAP community? Are there any lessons to be learned from these incidents?

A new National Geographic docuseries by investigative journalist Leslie Kean aims to shed light on the modern UFO phenomenon.

Analysis of space junk that has fallen to Earth could help researchers design rockets and spacecraft that break up more completely during the reentry process.

The coming year will surely see a persistence of debate, discussion and disbelief regarding unidentified anomalous phenomena.

Space.com caught up with Tim Dodd in an exclusive interview to discuss his 'Everyday Astronaut' status and how he's preparing himself for his citizen voyage to the moon and back.

Space mining has matured to the point where there are dozens of startup companies planning to begin harvesting valuable resources from space.

Solar sailing can be a relatively slow-motion affair, but progress in the nascent field is quickly gaining steam.

China's last space launch of 2022, which lifted off on Thursday (Dec. 29), has prompted a warning of falling rocket debris from the Philippine Space Agency.

Nuclear fusion has broad implications, fueling hopes of clean, limitless energy and the long-held dream of future rockets that are driven by nuclear propulsion.

China may end up enlarging its Tiangong space station and perhaps use it to evaluate technologies needed for possible human exploration of the moon.

NASA has built a new rocket and spacecraft to get Artemis astronauts to the moon, and it's developing a new toolkit for them to use on the lunar surface as well.

UFOs are making headlines again, but lost in the hype and ruckus is the question of when this all started and how we got to this point.

The crewmembers of the Polaris Dawn mission are busily training for their orbital flight early next year, one that will see the first commercial spacewalk.

As multiple nations plot out their moon exploration strategies, how best to survive the lunar night gives space engineers the cold sweats.

The U.S. military's X-37B robotic space plane just passed 900 days in orbit on its latest hush-hush mission, adding to the program's flight-duration record.

It's important to start taking action against space junk now, experts say, because Earth orbit is only going to get more congested.
