SVOM

French-Chinese Gamma-Ray Burst Detection Satellite · CNES (France) / CNSA (China)

SVOM launched just two days after the first Kinéis satellites reached orbit — a coincidence, but a fitting one, since SVOM represents an entirely different kind of French-led space ambition: hunting gamma-ray bursts, the single most energetic explosions in the universe since the Big Bang, typically marking the death of a massive star collapsing into a black hole. Built jointly by France's CNES and the Chinese space agency CNSA — a genuinely rare France-China scientific space collaboration — SVOM can detect a burst, calculate its position, and alert ground telescopes worldwide within minutes, catching an afterglow that fades within hours of the initial explosion.
