Trisat-S Nanosatellite Captures 'Black Sun' Effect to Validate Autonomous Navigation

The Trisat-S nanosatellite, launched in September 2026, successfully captured an image of the Sun exhibiting the 'Black Sun' effect, where extreme brightness causes sensor pixels to appear dark. This visual artifact, rather than a failure, serves as a critical reference point for determining a spacecraft's attitude and orbit. The mission, led by the University of Maribor and SkyLabs, aims to develop miniaturized imaging technology for autonomous navigation in deep space. The satellite also tested advanced hibernation technologies and was launched by Isar Aerospace, marking the first European company to reach orbit with its own launch vehicle.

"SpaceX Partners with Unseenlabs to Enhance Maritime Surveillance"

French maritime surveillance provider Unseenlabs plans to expand its constellation with the launch of its 12th and 13th nanosatellites on a SpaceX Falcon 9 rocket, aiming to offer near-real time maritime surveillance services by the end of 2025. The constellation, currently consisting of 11 satellites, can monitor and track signals from ships every four to six hours, providing valuable data for commercial and government customers. Unseenlabs aims to launch a total of 25 satellites by 2025 to enable a revisit time of around 30 minutes over the same area, enhancing services for environmental monitoring, maritime disaster response, and pollutant emissions tracking.

Cosmonauts Brave Coolant Mishap During Spacewalk on ISS

Roscosmos cosmonauts successfully completed a spacewalk, inspecting the Nauka module radiator and releasing a nanosatellite. However, they encountered a coolant leak and partial solar sail deployment issues. The cosmonauts wiped down their suits and tools to prevent contamination before reentering the space station. This was the sixth spacewalk for Oleg Kononenko and the first for Nikolai Chub. NASA astronauts Loral O'Hara and Jasmin Moghbeli are scheduled for the next spacewalk to replace faulty equipment and complete maintenance tasks.

"Spacewalking Cosmonauts Successfully Locate and Address ISS Radiator Coolant Leak"

Russian cosmonauts conducted a spacewalk outside the International Space Station to isolate a leaking radiator and observed residual coolant spewing out into space. One of the cosmonauts attempted to sop up the pooling coolant but was instructed to leave the area when some liquid reached a safety tether. The cosmonauts also worked on attaching a synthetic aperture radar antenna and released a small student-built nanosatellite, although the solar sail propulsion system failed to deploy. The radiator's installation had gone normally, but on October 9, frozen coolant flakes were observed streaming from the radiator. This marks the third coolant leak incident for the Russians in less than a year.
