Dr. John Barentine FRASThe updated text of the #EU #Space Act (https://data.consilium.europa.eu/doc/document/ST-16437-2025-INIT/en/pdf) removes the previous requirement for satellites to be fainter than 7th magnitude at all times. It now merely calls on operators to "minimise the impact of satellites on astronomical observations" without stipulating any particular brightness threshold.
The updated version of Article 72 now reads: “Union spacecraft operators shall establish a plan containing measures that are adequate to limit light and radio pollution in accordance with paragraph 2. That plan shall include all of the following elements: (a) a description of the technical and operational measures implemented by the Union spacecraft operator to reduce the visible brightness of the spacecraft and to minimise the impact of satellites on astronomical observations, including through low reflectivity coating or shielding; (b) a description of the technical and operational measures implemented by the Union spacecraft operator after the end of life to limit disruptions for radio astronomy observatories and to minimise the impact of satellites on astronomical observations.”

“Reflections cast by a growing number of #satellites orbiting the Earth could ruin more than 95% of images taken by some #space telescopes in the next decade, according to a #NASA-led study. The reflected light shows up as streaks called satellite trails. It's been seen in images taken by NASA's Hubble Space Telescope. The situation is only getting worse as more satellites accumulate in orbit, according to researchers.”
Mike K3LOEFirst attempt at receiving #sstv from #RS38S was a bust. It was also the first time I tried to program my GD77 with qdmr. I think I got that wrong.

Study by The Ohio State University Highlights LEO Satellites as Potential GPS Alternatives for Enhanced Arctic Navigation
Researchers are investigating the use of LEO satellites as a backup for GPS navigation, particularly in challenging environments like the Arctic, to enhance accuracy and security against signal disruption.
