What went wrong with Artemis I was on the launch pad at Kennedy Space Center, so that's where NASA has decided to try and fix it.... Read more

Space travel to the moon, Mars, and beyond can expose astronauts to extreme conditions, causing potential health issues. To prepare for future long-duration missions, NASA studies how the effects of space—changes in gravity, radiation, and more—impact "model organisms," or other kinds of life that are biologically similar to humans. New... Read more

Space is a hostile, extreme environment. It's only a matter of time before ordinary people are exposed to this environment, either by engaging in space tourism or by joining self-sustaining colonies far away from Earth.... Read more

In the early hours of Sunday, September 4, Solar Orbiter flew by Venus for a gravity-assist maneuver that alters the spacecraft's orbit, getting it even closer to the sun. As if trying to get the orbiter's attention as it cozied up to another body in the solar system, the sun... Read more

How many intelligent civilizations should there be in our galaxy right now? In 1961, U.S. astrophysicist Frank Drake, who passed away on September 2 at the age of 92, came up with an equation to estimate this. The Drake equation, dating from a stage in his career when he was... Read more

In 1982, author James Michener published his sprawling novel "Space." In it, he describes a fictional Apollo 18 mission to the moon. While the astronauts are on the surface, the sun unleashes a huge storm, trapping them outside of their protective capsule. The two men get blasted by lethal amounts... Read more

Rice is one of the world's staple crops. It is regularly eaten by more than half the world's population. And now, it's been grown in microgravity, on board the newly launched Chinese Wentian space laboratory.... Read more

A little Martian dust appears to go a long way. A small amount of simulated crushed Martian rock mixed with a titanium alloy made a stronger, high-performance material in a 3D-printing process that could one day be used on Mars to make tools or rocket parts.... Read more

While hundreds of thousands of people made their way to the Space Coast two weekends in a row for a shot to see the most powerful rocket to ever lift off from Earth, a couple of scrubs for NASA's Artemis I mission left them disappointed.... Read more

Astronauts with their sights on the moon are receiving world-class geology training during the fifth edition of ESA's Pangaea campaign. From choosing landing sites for a future Artemis mission, to designing science operations for the lunar surface, the course challenges space explorers to become field scientists.... Read more

Reusable rocket engines have become all the rage lately, even as NASA's continually delayed Artemis I mission attempts to launch with non-reusable technology. Realistically, the only way to significantly lower launch costs is to reuse the engines rather than build them from scratch every time. Another small start-up company, RocketLab,... Read more

NASA has revamped its "Eyes on the Solar System" 3D visualization tool, making interplanetary travel easier and more interactive than ever. More than two years in the making, the update delivers better controls, improved navigation, and a host of new opportunities to learn about our incredible corner of the cosmos—no... Read more

After scrapping a second attempt to get its new 30-story lunar rocket off the ground due to a fuel leak, NASA officials said Saturday it may not be possible to try again this month.... Read more

NASA's new moon rocket sprang another dangerous fuel leak Saturday, forcing launch controllers to call off their second attempt to send a crew capsule into lunar orbit with test dummies.... Read more

After technical issues halted its first launch attempt, NASA will try again on Saturday to get its new 30-story rocket off the ground and send its unmanned test capsule towards the Moon.... Read more
