NASA used Anthropic’s Claude AI to pilot Perseverance across 1,500 feet of Mars, a milestone that could soon automate complex planetary navigation.

Elon Musk merges SpaceX and xAI in history’s biggest merger as part of a long-term plan to launch AI data centers into orbit.

The new results provide the tightest constraints yet on the universe's expansion and represent the culmination of 25 years of scientific research.

Amid federal funding uncertainty, commercial spaceflight saw highs and lows, a comet from another star surprised us, and the Vera C. Rubin Observatory began its 10-year survey.

Technicians have resolved a helium flow issue that forced a rollback to the Vehicle Assembly Building last month, keeping an April launch within reach for NASA’s return to the Moon.

Researchers smashed an extremophile bacterium with steel plates to simulate an asteroid impact — and found it nearly impossible to kill, adding some credence to the theory that life could travel between planets.

A newly peer-reviewed paper adds scientific weight to the claim that a leopard-spotted rock found in Jezero Crater may hold the fossilized signatures of ancient martian microbes — though the claim is still far from proven.

A massive star’s collapse may have birthed two tiny neutron stars that spiraled together and merged before they could even leave their parent’s side.

Here’s what’s launching from Nov. 3 to Nov. 9: Blue Origin's New Glenn rocket is set to fly its second mission, carrying NASA’s ESCAPADE probes to Mars. Other major flights include Europe's Sentinel-1D satellite, ULA's launch of the massive ViaSat-3 F2 satellite, and several missions from SpaceX and China.

As of Oct. 1, approximately 15,000 NASA employees are furloughed, and most operations halted except for the International Space Station, satellites, and the Artemis program.

Experts say it remains unclear exactly what sort of glitch Airbus uncovered that prompted it to ground the A320 fleet, but radiation in space is well known for its potential to wreak havoc with electronics.
