Scientists are using the Mojave Desert to test robots for the next space age.

The Geminids are one of the best and most visible annual meteor showers, when at least 120 meteors can usually be seen per hour. But 2024 will be different, thanks to the year's final full moon.

The mission to take four astronauts on a trip around the moon and back, previously targeting a launch at the end of 2025, has been delayed until at least April, 2026.

China declared a “complete success” after it launched a new three-person crew to its space station early Wednesday as the country seeks to expand its exploration of outer space.

Three NASA astronauts and a Russian cosmonaut splashed down off the Florida coast early Friday, capping a nearly eight-month science and research mission to the International Space Station.

Europa Clipper will make a six-year journey to Jupiter to study Europa, an icy-surfaced moon that scientists believe has “ingredients for life.”

SpaceX conducted its fifth flight test of Starship, its most powerful spacecraft.

With each launch, SpaceX has been discharging tens of thousands of gallons of industrial wastewater into sensitive wetlands. Environmentalists say an increase in launches will only make things worse.
