After 16 years studying Earth's highest clouds for the benefit of humanity—polar mesospheric clouds—from its orbit some 350 miles above the ground, NASA's Aeronomy of Ice in the Mesosphere, or AIM, mission has come to ...
Decades before any probe dips a toe—and thermometer—into the waters of distant ocean worlds, Cornell astrobiologists have devised a novel way to determine ocean temperatures based on the thickness of their ice shells, ...
A frequent idea in sci-fi and apocalyptic films is that of an asteroid striking Earth and causing global devastation. While the probabilities of this kind of mass extinction occurring on our planet are incredibly small, they ...
NASA has big plans for its Artemis program—to return Americans to the moon for the first time since 1972 and establish a lunar base for humans by the end of the decade.
A private Houston-based company is set this week to lead a mission to the moon which, if successful, will mark America's first lunar landing since the end of the Apollo era five decades ago.
