NASA has turned off one of Voyager 2's science instruments as power conservation becomes crucial for the interstellar exploring spacecraft located 12.8 billion miles from home.

The U.S. Federal Aviation Administration is investigating the uncontrolled reentry of part of a Falcon 9 rocket that delivered passengers to the International Space Station in a capsule that will return stranded astronauts Butch Wilmore and Suni Williams to Earth next year.

A new study reveals that Generation 2 Starlink satellites are leaking up to 30 times more radio waves than their predecessors. If SpaceX continues to deploy the newer versions as planned, we could reach an "inflection point" where astronomers can no longer properly study the cosmos, researchers warn.

60-year-old Oleg Kononenko has safely returned to Earth following a record-breaking year-long stint onboard the International Space Station. His latest trip to space means he has now spent more time in orbit than any other human.

JUICE successfully identified water and the building blocks of life in Earth's atmosphere. In doing so, the probe headed for Jupiter's moons confirmed that its instruments are working properly.

NASA's most distant spacecraft had a critical thruster problem far from home. Fixing it required a long-distance call to overcome extreme cold and dwindling power.

The first phase of China's moon base will be completed around 2035 near the lunar south pole, and an extended model will be built by about 2050, if all goes according to plan.

SpaceX Polaris Dawn astronaut Jared Isaacman briefly "touched the void" as he embarked on the first-ever private spacewalk Thursday (Sept. 12).

With Boeing's Starliner spacecraft is safely back on Earth, NASA says Crew Flight Test astronauts Butch Wilmore and Suni Williams could have returned onboard.

NASA's testing a solar sail system in space, and the spacecraft that brought the tech there has snapped a photo.
