New data from the European Space Agency's Swarm satellites reveal that the South Atlantic Anomaly, a weak spot in Earth's magnetic field, has grown by nearly half the size of continental Europe since 2014. A region southwest of Africa is weakening even faster in recent years. This expansion highlights unusual activity in Earth's molten outer core.

A SpaceX Falcon 9 rocket stage re-entered the atmosphere uncontrollably in February 2025, releasing vaporised metals that drifted over Europe. Researchers detected a significant spike in lithium from the debris, marking the first tracing of such pollution to a specific spacecraft. This incident highlights growing concerns over atmospheric impacts from increasing satellite launches.

A innovative UK satellite named CarbSAR is set to launch on Sunday, featuring a radar antenna made from knitted tungsten wire. Developed by Oxford Space Systems in partnership with Surrey Satellite Technology, it aims to capture high-resolution images of Earth's surface. The technology could pave the way for a future defence satellite network.

Il ministero della Difesa spagnolo ha segnalato l’impatto di una particella spaziale sul satellite SPAINSAT-NG II di Hisdesat durante il suo viaggio verso l’orbita finale. Nessuna interruzione si è verificata nei servizi di comunicazione o nelle operazioni delle forze armate. La copertura satellitare resta pienamente garantita da altri satelliti operativi.

Intuitive Machines, known for its lunar landers, has announced an $800 million acquisition of satellite manufacturer Lanteris Space Systems. The deal, expected to close early next year, will expand the company's capabilities into satellite production and military contracts. This move positions Intuitive Machines as a major player in both commercial and national security space sectors.

A study of a May 2024 solar storm reveals significant disruptions to SpaceX's Starlink constellation, including altitude drops and network outages. Researchers warn that as satellite numbers increase, the threats from solar activity could worsen, potentially leading to collisions and communication failures. The findings highlight vulnerabilities during the sun's 11-year activity cycle.
