The NASA/ESA Hubble Space Telescope reobserved interstellar comet 3I/ATLAS on 30 November with its Wide Field Camera 3 instrument. At the time, the comet was about 286 million km from Earth. Hubble tracked the comet as it moved across the sky. As a result, background stars appear as streaks of light.

Hubble previously observed 3I/ATLAS in July, shortly after its discovery, and a number of observatories have since studied the comet as well. Observations are expected to continue for several more months as 3I/ATLAS heads out of the solar system.

Italy's IRIDE Earth observation programme has expanded with the launch of eight Eaglet II satellites, adding a second constellation to the growing national fleet. The spacecraft rode into orbit on a Falcon 9 mission that lifted off from Vandenberg Space Force Base in California at 19:44 CET on 28 November, with deployment completed about an hour after launch and signals from all satellites later

Two new ICEYE radar satellites have entered service under Greece's National Small Satellite Programme, expanding the country's capacity to track floods, wildfires, landslides and other hazards as well as areas of security interest on land and at sea. The pair of synthetic aperture radar spacecraft were launched on 28 November 2025 on SpaceX's Transporter-15 rideshare mission from Vandenber

An international team from Japan, Malaysia, the UK, and Germany has proposed that life on Earth may have emerged within sticky, surface-bound gels that formed before the first cells. The researchers argue that these prebiotic gels, attached to mineral or other surfaces, could have provided both structure and chemical environments that helped early chemistry progress toward biology. The tea

The OTTER Optical Traffic Tracking Experiment for Responsive Space satellite has entered service in orbit to support maritime monitoring following its launch on 28 November 2025 into an orbit at about 500 kilometres altitude. The nanosatellite has a mass of roughly six kilograms, is comparable in size to a shoebox and deployed its solar panels and instruments after separation from the launcher.

Pulsar Fusion and partners have tested what they describe as the largest space plasma engine yet fired in Britain, designed to provide high-thrust in-space propulsion for heavier satellites. The engine, which the company reports is roughly ten times larger than its previous plasma thrusters, was demonstrated at the University of Southampton on 29 January in a large vacuum chamber to replicate on

The Center for Advancement of Science in Space will continue to manage the International Space Station National Laboratory for at least another five years, CASIS announced on Thursday. CASIS has managed the ISS National Lab since 2011, after Congress created it to enable researchers to build a "robust market" in low Earth orbit by leveraging the unique environment that exists in space, CAS

The United States has entered a consequential new era of competition with China in space - one that lawmakers said will shape global power, economic security and military advantage for generations. House Science, Space and Technology Space and Aeronautics Subcommittee Chairman Mike Haridopolos, R-Fla., posed the issue during a hearing Thursday as a question for the future. "Will huma
