Prompt-Driven AI Models Enable On-Orbit Spacecraft Inspection Without Retraining
Researchers demonstrate that prompt-driven vision-language models can perform zero-shot instance segmentation of spacecraft components on orbit without modifying onboard weights, enabling post-launch semantic expansion. The approach achieves 0.385 mAP@0.5 on a test set of 129 images of unseen satellites, with strong performance on large structures but challenges on fine-scale appendages. Structured prompts improve accuracy by up to 82% over simple category names.
Technology European GPS Disruptions Linked to Russian Satellites
Research from the University of Texas and Stanford University suggests that Russian satellites are behind GPS interference in Europe. The study identifies the Russian satellite Kosmos 2546 as a potential source, raising concerns about electronic warfare.
Technology FCC Grants Amazon Extension for Satellite Launch
The FCC has granted Amazon an extension for launching its Leo satellite constellation due to rocket capacity issues. This decision, opposed by SpaceX, allows Amazon more time to deploy its satellite internet service.
