If founder Elon Musk’s vision comes to pass, later this decade SpaceX’s Starship could transport astronauts and private passengers to the moon—and perhaps a decade or two later, to Mars. Last weekend’s second near-orbital test flight of the huge rocket fared better than the first one on April 20, surviving …

SpaceX’s Starship failed its test flight this morning when the automated flight termination system triggered, and engineers lost contact with the craft about 10 minutes into its journey. This marks the company’s second attempt at sending a Starship on a near-orbital trip, a 90-minute voyage that would have gone almost …

By the 2030s, if NASA’s and other space agencies’ plans come to fruition, astronauts and the occasional tourist group will frequently visit the moon. Not long after that, they’ll be able to live for extended periods on lunar outposts, much like astronauts do in space stations today. By the 2040s …

Scientists leading the European Space Agency’s Euclid space telescope mission have just released its breathtaking first science images, taken only four months after launch. These new space photos reveal spectacular snapshots of the vast structure of the cosmos, including a massive galaxy cluster in the Perseus constellation, an object nicknamed …

One might expect astronomers to have found all the near-Earth asteroids and comets already. But that’s not the case. Some lurk in orbital spots that are hard to see, because discovering them requires looking straight into the sun. One such object, dubbed Kamo’oalewa, evaded detection until seven years ago—and its …

Rare, fleeting radio flashes in the sky have bewildered astronomers for more than a decade. These “fast radio bursts,” blips that flare and then disappear in a couple seconds or less, flit in and out of existence so quickly that astronomers struggle to study them, let alone pinpoint their cosmic …

Everyone’s into asteroids these days. Space agencies in Japan and the United States recently sent spacecraft to investigate, nudge, or bring back samples from these hurtling space rocks, and after a rocky start, the space mining industry is once again on the ascent. Companies like AstroForge, Trans Astronautica Corporation, and …

A rad moon’s on the rise. Early on October 14, our lunar satellite will briefly hover before the sun, obscuring the dawn and immersing millions of people in a strange morning gloom. But this annular eclipse will not be total: Since the moon’s traveling at the more distant part of …

NASA’s Psyche spacecraft blasted off this morning at 10:20 am Eastern time and is now en route to its namesake metal-rich asteroid. The long-delayed mission will examine the asteroid with a suite of scientific instruments and determine whether the hunk of rock was the core of a baby planet that …

At long last, NASA’s curation scientists have revealed what OSIRIS-REx ferried back from an asteroid 100 million miles away. The seven-year mission scooped up a rock sample from Bennu in 2020, then returned it to Earth in September, parachuting it down into the Utah desert. Scientists painstakingly cleaned and shipped …
