Scientists propose that a moon base could act as an isolated first line of biological defense against extraterrestrial samples that might be harmful to Earth's biosphere.

The existence of evidence for Earth’s past equatorial ring, shown by impact craters, raises questions about its loss. Modeling its effects on Earth's rotation presents challenges. However, current findings indicate minor impacts on day length, with significant stability in the Earth-Moon system over 10,000 years.

About 63 hours after its launch, Surveyor 1 landed on the Moon on June 2, 1966. The 2,200-pound (998 kilograms) craft touched down inside a 62-mile (100 kilometers) crater north of Flamsteed Crater in Oceanus Procellarum, or the Ocean of Storms. Surveyor 1 took more than 11,000 photos, and measured the Moon’s temperature and theContinue reading "June 2, 1966: Surveyor 1 lands on the Moon"

Blue Moons are known for the folklore surrounding their appearance in the skies. But the real thing has less to do with its color and more with the timing of the year’s Full Moons. The next Blue Moon is May 20, 2027. It will be a seasonal Blue Moon; here’s what that is: There areContinue reading "What is a Blue Moon? When’s the next one?"

The phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under sunlight. Thanks to the Moon’s orbit around Earth, the angle of sunlight hitting the lunar surface and being reflected back toContinue reading "2026 Full Moon calendar: When to see the Full Moon and phases"

NASA envisions its moon base covering hundreds of square miles, and hopping scout drones may mark the facility's perimeter. The agency just awarded $1 billion in contracts to get the ball rolling.
