Using knives and shears, a pair of Russian spacewalkers Tuesday cut samples of material around a mysterious hole in a Soyuz spacecraft docked on the International Space Station that a Moscow official suggested could have been deliberate sabotage.

China launched a rover early Saturday morning destined to land on the far side of the moon, a global first that would boost Beijing's ambitions to become a space superpower.

NASA's first-ever mission designed to visit an asteroid and return a sample of its dust back to Earth arrived Monday at its destination, Bennu, two years after launching from Cape Canaveral, Florida.

The $800 million unmanned mission, known as OSIRIS-REx, made a rendez-vous with the asteroid at around 12:10 pm (1710 GMT), firing its engines a final time.

Russia's space agency Roscosmos said Monday that the first manned Soyuz flight to the International Space Station since a failed launch in October was proceeding according to plan.

NASA chief Jim Bridenstine elaborated this week on the reasons why the US space agency launched a safety review of SpaceX and Boeing, which are building spaceships for astronauts, including their workplace culture and drug-free policies.

Although NASA initially declined to confirm media reports that the review was prompted by SpaceX CEO Elon Musk's appearance on a filmed podcast in which he was smoking a joint, Bridenstine admitted Thursday, during a roundtable with reporters, it "was not helpful."

The Chinese scientist who claims to have created the world's first genetically-edited babies defended the highly controversial procedure Wednesday, but announced a halt to the trial following an international outcry.

Are champions born, or raised? That's the question scientists in Argentina are trying to answer as they look to pinpoint the genes that make local horses the best in the world for playing polo.

Cheers and applause erupted at NASA's Jet Propulsion Laboratory on Monday as a waist-high unmanned lander, called InSight, touched down on Mars, capping a nearly seven-year journey from design to launch to landing.

A scientist in China claims to have created the world's first genetically-edited babies, a move that would be a ground-breaking medical first but which has generated a barrage of criticism.

Kurt Eberly has hardly any hair and keeps losing more. His job is to launch, two times per year, a metallic cylinder packed with several tons of supplies, at high speeds toward the International Space Station, 250 miles (400 kilometers) above the Earth.
