NASA's twin Voyager probes have become, in some ways, time capsules of their era: They each carry an eight-track tape player for recording data, they have about 3 million times less memory than modern cellphones, and they transmit data about 38,000 times slower than a 5G internet connection. Yet the Voyagers remain on the cutting edge of space exploration.

NASA's Artemis 1 moon rocket headed back to the launch pad Tuesday night (Aug. 19) to take a step closer to a landmark lunar mission. Artemis 1 is an uncrewed test flight of the huge Space Launch System (SLS) megarocket and its Orion spacecraft, and it began the rollout to a Kennedy Space Center launch pad at about 10 p.m. EDT (0200 GMT Wednesday, Aug. 17). By 7:30 a.m. EDT, it had reached its destination.

Never let it be said that Rocket Lab founder Peter Beck lacks a flamboyant streak. Although his Electron launch vehicle is one of the smallest orbital rockets in the world, Beck gleans every bit of performance from the booster he can. On just the rocket's second launch, in January 2018, he added a disco-ball like geodesic sphere called "Humanity Star" to give humans a small and bright shining object to, however briefly, gaze upon in the night sky.

Rick LaBrode has worked at NASA for 37 years, but he says the American quest to return to the Moon is by far the crowning moment of his career. LaBrode is the lead flight director for Artemis 1, set to take off later this month—the first time a capsule that can carry humans will be sent to the Moon since the last Apollo mission in 1972.

When Axiom Space sent the first private crew to the International Space Station earlier this year, an overly aggressive itinerary caused some ripples in the professional astronauts’ work performance. Though it’s unclear if the trip interfered with the ISS crew’s science goals, the atmosphere aboard the station was strained—a classic example of too many cooks in the kitchen.

After a number of delays, NASA's Artemis I moon mission is inching awfully close to the finish line. As of this week, the agency confirmed it's preparing for an Aug. 29 liftoff, targeting date No.1 on a list of three possible windows. "We've basically got a date with the range on the 29th of August," Mike Sarafin, Artemis I mission manager, said in a Wednesday press conference, referring to the rocket's future blastoff location.

A stunning image captured by the James Webb Space Telescope has given us the clearest look of the Cartwheel Galaxy so far. NASA released the image Tuesday of the distant galaxy — named for its resemblance to a wagon wheel. The Cartwheel Galaxy is located about 500 million light-years away in the Sculptor constellation, the agency said in a press release.

NASA's trio of robots known as Astrobee have completed the first phase of a project to test whether an autonomous system can provide spacecraft monitoring, maintenance and incident response. NASA's 12-inch wide cube-shaped robots are more like a flying Roomba than a Boston Dynamics dog or humanoid; more like Weebo, the flying assistant in the 90s' Robin Williams sci-fi/comedy Flubber, than Terminator.

NASA has completed the next steps in the Artemis 1 mission — installing the data-gathering mannequin Commander Moonikin Campos inside the Orion spacecraft that will launch to the moon atop a brand-new megarocket.

Earlier this week, Russia indicated that it was not extending the current cooperation agreement for the International Space Station, which expires in 2024, and would be departing the project after that. Nearly everyone noticed that there was no actual departure date specified, leaving open the possibility that it would continue its participation without a formal agreement in place. That now seems to be what will happen.

Boeing disclosed a charge of $93 million in the second quarter for its Starliner astronaut capsule program, bringing the program’s overrun costs to nearly $700 million.

China’s latest launch of a rocket is, once again, raising alarm that the debris will crash into the Earth’s surface in an uncertain location and at great speed.

As countries and private companies ramp up space exploration, the issue of where and how abandoned rockets re-enter Earth is becoming more significant. Over the next decade, if current practices of uncontrolled rocket re-entries continue, there is a roughly 10 percent chance that one or more casualties will occur, and they will most likely be in the Global South, according to a new study published in Nature Astronomy on Monday.

NASA has reported that a meteoroid hit on the James Webb Space Telescope has caused "significant uncorrectable" damage to one of the panels it uses to stare into deep space. The orbiting observatory was launched last December and recently released a full set of new observations, including what is said to be the "deepest" and most detailed picture of the cosmos to date.

NASA and the Russian space agency Roskosmos have signed a long-term agreement to complete flights to the International Space Station (ISS), which will allow Russian cosmonauts to fly to the space station on US spacecraft in exchange for Americans being able to travel with Russian Soyuz spacecraft, Roskosmos announced today.

A new space waste disposal method has been tested on the International Space Station (ISS), disposing of approximately 172 lbs of garbage—including dirty crew clothing and used office supplies.

At last! After much anticipation, President Joe Biden will reveal the first science-quality, full-color image from NASA's James Webb Space Telescope, NASA confirmed in a tweet.

A team of Canadian engineers have built a gun that will help space agencies test materials that could provide shielding against space debris!

We finally have hints of what the first operational images will be from NASA's deep-space observatory. Among the first pictures coming in from the $10 billion James Webb Space Telescope will be "the deepest image of our universe that has ever been taken," according to NASA administrator Bill Nelson.

A new simulation of NASA's Double Asteroid Redirection Test (DART) mission suggests that rather than leaving a crater behind, the DART impactor could severely deform the small asteroid it will collide with.
