After a Falcon 9 rocket stage burned up in the atmosphere, vaporised lithium and other metals drifted over Europe. A SpaceX rocket that burned up after re-entering the atmosphere unleashed a plume of vaporised metals over Europe, a type of pollution that is expected to increase as spacecraft and satellites multiply. The upper stage of a Falcon 9, which is designed to splash down in the Pacific Ocean for possible re-use, lost control due to engine failure and fell from orbit over the north Atlantic in February 2025. We're finally solving the puzzle of how clouds will affect our climate People across Europe saw fiery debris streaking through the sky, some of which crashed behind a warehouse in Poland. Seeing the news, Robin Wing at the Leibniz Institute of Atmospheric Physics in Germany and his colleagues turned on their lidar, an instrument for atmospheric sensing.

Old rocket parts and decommissioned satellites are whizzing around in low Earth orbit, where they risk colliding with the ever-growing constellations of modern satellites being launched. A new listing of the 50 most concerning pieces of space debris in low-Earth orbit is dominated by relics more than a quarter-century old, primarily dead rockets left to hurtle through space at the end of their missions. "The things left before 2000 are still the majority of the problem," said Darren McKnight, lead author of a paper presented Friday at the International Astronautical Congress in Sydney. "Seventy-six percent of the objects in the top 50 were deposited last century, and 88 percent of the objects are rocket bodies. That's important to note, especially with some disturbing trends right now."

The massive 400ft Starship rocket has been assembled on a launch platform by SpaceX, ahead of an announcement on the future of the heavy lift launcher tonight. Founder Elon Musk announced his plan to reveal details about the future of the massive, and fully re-usable spacecraft, starting at 21:00 ET, from Boca Chica, the home of the SpaceX Starship test facility in Texas. It will be the first update on the vehicle in almost three years, and while details haven't been revealed over what Musk will say, it will likely include details of the first orbital test launch for the next generation rocket. Starship, which will return humans to the lunar surface and could one day ferry more than 100 people a time to Mars, is set to make its first orbital flight in March. The latest development in Boca Chica saw the firm stack a two-stage Starship rocket - with the upper stage being lifted on to the Super Heavy booster using a trio of robotic arms attached to the 480ft launch tower.

This piece was originally published in Wired and appears here as part of our Climate Desk Partnership. In early October, a dead Soviet satellite and the abandoned upper stage of a Chinese rocket narrowly avoided a collision in low Earth orbit. If the objects had crashed, the impact would have blown them to bits and created thousands of new pieces of dangerous space debris. Only a few days prior, the European Space Agency had published its annual space environment report, which highlighted abandoned rocket bodies as one of the biggest threats to spacecraft. The best way to mitigate this risk is for launch providers to deorbit their rockets after they've delivered their payload. But if you ask Jeffrey Manber, that's a waste of a perfectly good giant metal tube.
