A problem with a helium valve on the Space Launch System moon rocket’s upper stage will require ground teams to only partially load the giant launcher with cryogenic propellants during an upcoming countdown dress rehearsal, NASA officials said Saturday.
Two microphones on Mars, carried on NASA's Perseverance rover, are for the first time revealing the sounds of another planet.
A SpaceX Dragon capsule carrying the four Ax-1 astronauts docked with the International Space Station at 8:29 a.m. EDT (1229 GMT) today (April 9), ending a 21.5-hour orbital chase.
Scientists have crafted a new message for intelligent extraterrestrials
The astronauts of the first-ever fully private crewed mission to the International Space Station will commemorate their groundbreaking flight with some digital artwork.
We round up the best stargazing tents for all situations, from solitary travelers to hosting parties.
A spinning orb of light that slowly moved across the sky in Alaska on March 29 was actually frozen fuel left by a Chinese rocket, according to experts.

The planets Venus, Mars and Saturn appear close together in the southeast predawn sky, while the moon passes near the bright stars Castor and Pollux on April 9.
The European Space Agency (ESA) is learning how to touch down safely at the South Pole of the Moon, without ever leaving Earth. Actual Moon landings seem to be on the horizon in the next decade via the Artemis program, and astronauts are going to have to learn to handle the unique challenges of landing in the Moon’s polar environment. With low angle sunlight and deep, permanently shadowed craters, the Moon’s South Pole poses difficulties no Apollo mission ever faced. To get hands-on experience with this environment without risking human life, ESA is putting astronauts through their paces on high-tech simulators.
A longed-eared toy dog was mistaken for a famous Disney rabbit when it was revealed as the "zero-g indicator" on the first private mission to the International Space Station.
Look up at the sky before sunrise Saturday (April 9) to see a trio of planets, twin stars and the moon entering its next phase.

Strapped in the seats of a SpaceX crew capsule, a retired NASA astronaut and three wealthy paying passengers rocketed into orbit Friday from the Kennedy Space Center on the first fully commercial mission to the International Space Station.
The James Webb Space Telescope continues to cool down out at its location at Lagrange Point 2, about 1.5 million kilometers from Earth. Since JWST is an infrared telescope, it needs to operate at extremely low temperatures, about 40 k (-223 degrees Celsius, -369.4 degrees Fahrenheit). But one instrument needs to be even colder.
With the private Ax-1 astronaut mission safely on its way to the space station, NASA plans to resume the "wet dress rehearsal" of its Artemis 1 moon mission this weekend.
Our Sun’s days are numbered. In about 5 billion years the Sun will expand into a red giant, casting off its outer layers before settling down to become a white dwarf. It’s the inevitable fate of most sunlike stars, and the process is well understood. But as a recent study shows, there are still a few things we have to learn about dying Suns.
Four private astronauts left Earth this morning (April 8), riding a SpaceX capsule toward the International Space Station on a history-making liftoff that wowed observers.
This morning, at 11:17 AM EDT (08:17 AM PDT), the first all-private astronaut mission to the International Space Station (ISS) lifted off from Launch Complex 39A at NASA Kennedy Space Center in Florida. Designated Axiom Mission 1 (Ax-1), this mission consists of four commercial astronauts flying aboard the SpaceX Dragon Endeavour spacecraft that launched atop a SpaceX Falcon 9 rocket. The launch was live-streamed via NASA’s official Youtube channel (you can catch the replay here).
The Hubble space telescope has a primary mirror of 2.4 meters. The Nancy Grace Roman telescope has one at 2.4 meters and the James Webb Space Telescope has a whopping 6.5 meter primary mirror. These are all fine and well to get the job done that they were designed for, but what if… we could have even bigger mirrors?
A tiny subatomic particle called the W boson may be heavier than scientists have previously thought and it could shake up physics' grand theory of everything.
