The Artemis II and III missions slated to return US astronauts to the Moon have been set back. At a press conference, NASA officials said that problems with the heat shield and life support systems would delay the launches until 2026 and 2027.

Astronomers have clocked a cosmic collision at 3.2 million km/h (2 million mph). A new instrument has spotted a galaxy crashing through a group of others at incredible speeds, creating a shock wave that’s changing the region completely.

The sixth flight of SpaceX's Starship went off today without a second capture landing of the Super Heavy first stage, but it did have a dramatic daylight powered soft landing of the Starship second stage in the Indian Ocean. And a banana.

If you've ever fancied yourself a spaceship architect that could design a vessel to carry colonists to another star system on a journey that could last for centuries, check out the Project Hyperion Design Contest, which invites teams to lay out their Generation Ship plans.

Oak Ridge National Laboratory and Sierra Space Corporation have developed a new heat shield based on venerable 1980s Space Shuttle technology to protect the next generation of reusable spacecraft from the deadly heat of reentry.

Flight 6 of SpaceX's giant Starship is scheduled to fly no earlier than Monday, November 18, 2024. If there are no delays, the world's largest rocket ever to fly will lift off at 4:00 pm CST from the company's Texas Starbase. Here's how to watch.

As the world watched slack-jawed while SpaceX's Super Heavy booster made the world's first tower capture landing after boosting the Starship 5 mission into orbit, few knew that the event came within one second of disaster.

Aliens might be able to detect us from the radio signals we beam to Mars to control our rovers there. Astronomers have now listened in on the nearby TRAPPIST-1 system to check whether aliens are chattering between their own neighboring planets.

In one of the strangest partnerships we've come across, Axiom Space and Prada (yes, that Prada) have teamed up to produce the space suits NASA astronauts will wear when they return to the Moon as part of the space agency's Artemis program.

In an astonishing bit of space gymnastics, SpaceX has pulled off a true first. It captured a Super Heavy booster at about 7:31 am CT using its own launch tower after delivering a Starship second stage to orbit, followed by a controlled reentry.

High-resolution images taken by the Hubble Space Telescope of Jupiter’s Great Red Spot have revealed that it’s not as stable as we thought. Instead, the Spot is squeezing in and out, with NASA describing it as “jiggling like a bowl of gelatin.”

Data from NASA's Curiosity rover collected on Mars is shedding new light on how the Red Planet became uninhabitable in the distant past due to a changing climate that caused the surface water to evaporate or be locked away as ice.

ESA's Hera spacecraft designed to assess NASA's experiment to deflect an asteroid has launched from Cape Canaveral Space Force Station, Florida. At 14:52 GMT, the robotic probe lifted off atop a Falcon 9 rocket to begin its three-year mission.

One picture taken every day of the year starting September 2023 through to September 2024 provides a pretty fascinating perspective of the twilight zone transit due to the Earth's 23.5-degree axial tilt as it orbits around the Sun.

The most abundant metal known to man is iron. It's everywhere. Not just on Earth, but in space as well. Astro engineers have just figured out how to use iron – or nearly any metal for that matter – as plasma rocket fuel.
