LeoLabs flags Starlink COPV anomaly
LeoLabs says a Starlink satellite likely suffered a COPV‑related propulsion failure and is fragmenting, with debris now on decaying orbits and expected to de‑orbit soon — a reminder of composite overwrapped pressure vessel and propulsion reliability risks in constellations. (x.com)
LeoLabs’ global radar network flagged a “fragment creation event” tied to Starlink‑34343 and reported “tens” of new objects in the satellite’s vicinity after the March 29 anomaly. (spacenews.com) (spacenews.com) The vehicle lost communications at roughly 560 km altitude (≈348 miles), where it had been operating since launch on May 27, 2025 from Vandenberg as part of Starlink Group 17‑1. (engadget.com) (engadget.com) (keeptrack.space) (keeptrack.space) LeoLabs said the motion and signatures of the liberated debris are “consistent with an internal energetic source rather than a collision with space debris,” a diagnostic the firm used to compare this event with a December 17, 2025 anomaly. (pcmag.com) (pcmag.com) (earthsky.org) (earthsky.org) A December 17, 2025 Starlink failure (sat‑ID 35956) involved venting of the propulsion tank, a roughly 4‑km rapid semi‑major axis decay and the release of trackable objects while the parent bus remained largely intact. (prismnews.com) (prismnews.com) SpaceX’s posts say the 34343 debris poses no new risk to the International Space Station or the upcoming Artemis II launch, and multiple trackers expect most of the fragments to reenter and burn up within weeks given the altitudes involved.
