+===== Yaogan-50 =====
+== Chinese Satellite Breaks Apart in Rare Orbit That Could Hold Debris for Centuries ==
+Yaogan-50 generated a large filed of debris in a highly retrograde orbit.
+Passant Rabie - September 8, 2026, 2:20 pm ET
+A reconnaissance satellite suffered an unidentified anomaly and broke apart into pieces. Now, those fragments are trapped in a high altitude above Earth, where they risk a head-on collision with another object.
+China’s Yaogan-50 (02) satellite launched on March 15, 2026, on board a Long March 6A rocket. The satellite successfully reached its operational orbit—a highly retrograde orbit, meaning that it travels in the opposite direction of Earth’s rotation at an altitude of approximately 590 miles (952 kilometers).
+A few months into its mission, however, the satellite appears to have malfunctioned. On September 4, the U.S. Space Force cataloged 43 debris objects from the breakup of Yaogan-50 (02), according to Jonathan McDowell, a former astrophysicist at the Harvard-Smithsonian Center for Astrophysics who tracks space activity.

+Planet Labs is a 15-year-old, San Francisco-based satellite manufacturer and constellation operator. They operate or have operated four different constellations throughout their history and capture imagery of the entire Earth's landmasses every day. As of this writing, LinkedIn lists the firm as having 1,751 associated members.
+Their CEO, Will Marshall, is one of the firm's three co-founders. In February, he posted images alongside the Secretary General of NATO, Mark Rutte, French President Emmanuel Macron and Kaja Kallas, who was Estonia's Prime Minister between 2021 and 2024 and is now Vice-President of the European Commission.

+===== Rassvet =====
+== Is Russia’s rival to Starlink failing? Here’s what we know. ==
+At least three of the first 32 Rassvet satellites likely suffered outright failures, and more may be in trouble.
+Stephen Clark – Sep 2, 2026 4:15 AM
+Russia’s attempt to replicate SpaceX’s Starlink satellite network seems to be moving as slowly as the front lines in eastern Ukraine.
+The Rassvet program, often billed as Russia’s answer to Starlink, started launching its first operational satellites earlier this year. Two launches, one in March and a second in July, have delivered 32 Rassvet satellites to low-Earth orbit, some 10 percent of the roughly 300 Rassvet spacecraft Russia aims to put into orbit by the end of next year to provide connectivity for military and civilian users. The company in charge of Rassvet, Bureau 1440, wants to deploy 924 satellites by 2035.
+But none of the 32 satellites launched so far have reached the 500-mile (800-kilometer) orbit they were designed to operate in. The rockets that launched the first two batches of Rassvets released the satellites much closer to Earth, and the satellites were expected to use their own plasma engines to raise their orbits over the next few months.
+The highest altitude achieved by the Rassvet satellites so far is a little more than 300 miles (500 kilometers). Twelve of the 16 Rassvet satellites from the first launch in March have settled into orbits at this altitude, according to an assessment released Monday by the Institute for the Study of War. A chart published by Jonathan McDowell, an independent tracker of global launch and satellite activity, indicates one more Rassvet satellite may soon climb above 300 miles.
