It sounded like a nightmare scenario: An astronaut commander on the International Space Station in distress, suffering from decompression sickness and a flight surgeon on Earth stuck in traffic giving advice that was broadcast live on an official NASA livestream.
International Space Station (ISS) Expedition 71 crew members Tracy Dyson and Matt Dominick will not be performing an extravehicular activity (EVA) that had been scheduled to begin Thursday (June 13) morning. The pair had already begun adorning their spacesuits when NASA announced the EVA's postponement, according to a space agency blog post this morning.
The same gigantic sunspot that was responsible for triggering a historic geomagnetic storm on Earth in mid-May whipped up a legendary one for Mars a few days later.
The aging but tenacious Hubble Space Telescope has beamed back yet another stunning photo of a distant galaxy. Hubble's latest view captures the barred spiral galaxy NGC 3059, which lies about 57 million light-years from Earth. The photo, released on June 7, was taken in May using the space telescope's Wide Field Camera 3 instrument as part of a broader galactic study
SpaceX is scheduled to launch 22 more of its Starlink broadband satellites to orbit from Florida's Space Coast on Thursday (June 13). The Starlink satellites will lift off atop a Falcon 9 rocket from Cape Canaveral Space Force Station during a two-hour window that opens at 4:46 p.m. EDT (2046 GMT). SpaceX had planned to launch the mission on Wednesday evening (June 12) but pushed the try back by about 24 hours.
Stoke Space has announced the first successful hot-fire test of an engine designed for its upcoming reusable rocket. The Kent, Washington-based company tested its new full-flow, staged-combustion (FFSC) rocket engine on June 5 at the company's test site in Moses Lake, Washington. Photos from the test show the engine kicking up a large plume of sand and rocks as the engine was throttled up to produce half of its maximum thrust.
Human technology like cell phones and broadcast towers constantly radiate radio waves into space, and astronomers estimate this tell-tale signature of humanity has swept across 75 nearby star systems, signaling to any watchful alien civilization that Earth hosts a technologically advanced species. And, while scientists have listened to the incessant radio chatter from our planet for a long time, in late February, they heard it from the moon for the first time.
In "Rogue," the latest episode of "Doctor Who," the Doctor and Ruby Sunday travel to the 19th century to enjoy the delights of Regency England. The dancing and high society romance are all very "Bridgerton" - or, for the benefit of older viewers, Jane Austen - but there's something amiss at the Duchess of Pemberton (Indira Varma)'s party.
Ed Stone, who led NASA's Voyager project, dies at 88 | Space Quiz! Which of these is blocked from reaching the surface of the Earth by the planet's atmosphere? | NASA weighs impacts of helium leaks on Boeing's Starliner

Ed Stone, who served as the project scientist for NASA's groundbreaking Voyager mission from 1972 to 2022, died on Sunday (June 9) at the age of 88. "Ed Stone was a trailblazer who dared mighty things in space. He was a dear friend to all who knew him, and a cherished mentor to me personally," Nicola Fox, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington, said in NASA's obituary for Stone, which the agency posted on Tuesday (June 11).
NASA astronauts Butch Wilmore and Suni Williams continue performing checkouts on their Starliner spacecraft, some of which are focusing on the potential effect of helium leaks, five of which have been detected on Starliner to date. One was spotted before launch but eventually deemed to pose little risk to full mission success. Four more have now been discovered while Starliner is in space, but that isn't necessarily cause for alarm.
On the nights before and after a new moon, when just a thin crescent is present, it is sometimes possible to make out the stunning effect known as Earthshine, or Da Vinci glow. The next new moon will occur on Friday, Ju...
Excitement is mounting for the first-ever return of samples from the far side of the moon. China's ongoing Chang'e 6 mission is nearing its departure from lunar orbit, after which it will deliver a mother lode of moon materials to Earth.

XRISM could change the way we see the X-ray universe, but a jammed door presents a mighty challenge. With the door closed, low energy X-rays are impossible to detect. But trying to open the door could put the rest of the mission at risk.
SpaceX posted on X a 25-second video of the final stages of Super Heavy's descent through Earth's atmosphere. The video, which combines footage from a boat or drone with that captured by Super Heavy's onboard cameras, captures the roar of the booster's Raptor engines as they fire in a landing burn just above the waves.
The four crew members of Inspiration4, the first ever all-civilian space mission, got genetically younger during their stay in space, a study has found. But the effects didn't last long. Scientists are now trying to unravel how the space environment affects human DNA.
A central component of NASA's science work is to help answer whether life has emerged elsewhere in the cosmos. So far, NASA has been looking tentatively in our own backyard -- the solar system - for signs that Earth may be just one of many homes to life.
