Energetic particles that arise when cosmic rays hit Earth’s atmosphere could help assess hidden damage to buildings in Ukraine after the war.

The 6mm hole was discovered accidentally in footage from an onboard camera.

Over 100 astronomers from leading U.S. universities have signed an open letter calling for an assessment of potential impacts of satellite megaconstellations on Earth's environment.

New technologies including recoverable satellites and in-orbit space debris recycling could help solve the satellite air pollution problem and prevent a new ecological crisis in the future.

Debris from the broken-apart Intelsat 33e telecom satellite is spreading across geosynchronous orbit, threatening spacecraft in this precious region of space, an animation shows.

A British startup plans to supply solar power from space to Icelanders by 2030, in what could be the world's first demonstration of the novel renewable energy source.

SpaceX's Starlink satellites now make up 40% of reentering satellite debris. But is Elon Musk's space company the worst polluter of Earth's upper atmosphere?

The growing number of rocket launches and satellites burning up in Earth's atmosphere could trigger the world's next big environmental emergency.

Air pollution from re-entering satellites is a potential environmental disaster that evades Earth-based laws, experts say.

Next-generation space debris protection material is being readied for a test trip to the International Space Station, to see how it holds up in the final frontier.

Europe's Mars Sample Fetch Rover showcased its sample-picking skills in field tests for the first time this month.

SpaceX's new Starlink satellites are so radio noisy that they could blind radio astronomy observatories to the universe's most intriguing phenomena, scientists say.

Japanese space-sustainability company Astroscale just signed a $90 million contract to take a bus-sized rocket stage out of orbit by the end of the decade.

A U.S. nonprofit organization has called on the U.S. Federal Communications Commission to pause satellite megaconstellation launches until their environmental impact can be assessed.
