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.

An Nvidia Jetson Orin NX chip, one of the most popular AI and edge computing GPUs, will launch to orbit soon, on SpaceX's Transporter 11 mission.

Space sustainability company Astroscale has launched a free computer game that allows players to test their space debris catching skills in a simulation based on the company's real mission.

Astroscale's ADRAS-J space debris inspecting mission completed a series of fly-around maneuvers of its target space junk, capturing stunning footage of a dead rocket stage in orbit.

An AI-powered weather model inspired by language-processing systems invented by Google is helping launch companies avoid disruptions to their busy schedules on Florida's Space Coast.

Astroscale's ELSA-M demo space junk collector will remove a defunct OneWeb satellite from orbit in 2027.

Satellites in SpaceX's Starlink megaconstellation made nearly 50,000 collision-avoidance maneuvers in the last six months, about double the number made in the previous half-year.

In May 2024, the most powerful solar storm to hit Earth in two decades caused chaos in space as it forced thousands of satellites to fight against thickening atmospheric gases to remain in orbit.

Satellites burning up in Earth's atmosphere are producing chemicals that could thwart the recovery of our planet's protective ozone shield.

Scientists have found that the members of the first all-civilian space mission, Inspiration 4, got genetically younger during their stay in space. But the effects did not last long.

A new report by NASA outlines the most promising approaches to keeping the space around Earth safe and usable for future generations.

The Space Trash Signs project has created "constellations" made of defunct satellites and old rocket parts to draw attention to the worsening space debris problem.

SpaceX's Starship will make space-based solar power cheaper than nuclear, gas and coal-based electricity generation, start-up Virtus Solis believes.

Reflect Orbital plans to launch a constellation of orbiting mirrors to beam sunlight to solar power plants on Earth after dark.

Japan will test solar power transmission from space in 2025 with a miniature space-based photoelectric plant that will wirelessly transmit energy from low Earth orbit to Earth.

A first-of-its-kind lab demonstration shows how solar power transmission from space could work.

Spanish start-up HALO Space has unveiled its capsule design for stratospheric space tourism.

Satellites in low Earth orbit can be hundreds of miles off their expected trajectories when bad space weather hits.

A total solar eclipse is not just an awe-inspiring natural phenomenon; it's an opportunity to expand our scientific understanding of the sun.

SpaceX's Starship uses greener propellant than other rockets, but its environmental footprint could still be substantial if plans for hundreds of launches per year come to pass, experts warn.
