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 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.

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 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.

Light from the half a million satellites that humanity is planning to launch into Earth's orbit in the coming years could contaminate almost all the images taken by space telescopes, NASA astronomers warned Wednesday.
Scientists have already been sounding the alarm about how light pollution from increasingly massive satellites threaten the future of dark skies seen from the ground.
