A spore is a bacterium's survival capsule: dried almost solid and wrapped in protein armor, with its chemical processes shut down. Bacteria enter this state of hibernation when environmental conditions are unfavorable. What's ...
Spacecraft propulsion traditionally relies on volatile fuels and separate, bulky systems for different types of maneuvering in space. NASA is working to change that. Engineers at NASA's Marshall Space Flight Center in Huntsville, ...
SpaceX launched its enormous Starship into orbit for the first time Monday and successfully delivered the most advanced Starlink satellites yet, but cut the flight short to ensure safety.
When a spacecraft reenters Earth's atmosphere at hypersonic velocities, its protective heat shield faces extreme conditions, including temperatures beyond 3,000 degrees Fahrenheit (1,650 degrees Celsius). To survive, the ...
What are the chances of finding extraterrestrial life in our solar system? Frank Postberg, a professor of planetary science at Freie Universität Berlin, has published a study in Science Advances with an international team ...
The robotic spacecraft that failed to rescue an aging NASA telescope plunged back to Earth on Friday less than three months after launching on the bold mission.
Wildfires can spread fastest when they tear through areas of dry vegetation. In contrast, vegetation that contains a lot of moisture can slow a wildfire's advance and give firefighting crews precious time to contain the blaze.
Like tendrils on a vine, lava spreads out from the northern crater of Krasheninnikov, a volcano pair on the Pacific coast of Russia's Kamchatka Peninsula. On July 30, 2025, an 8.8-magnitude earthquake struck in the nearby ...
During NASA's SpaceX Crew-13 mission aboard the International Space Station, astronauts will support a series of biomedical and human performance investigations, including a new collaborative effort to study how spaceflight ...
Rocket launches are among the most violent ways humans have devised to travel. They generate millions of pounds of thrust and subject passengers to intense g-forces. Humans must undergo serious training to withstand those ...
