Gaia leaves for retirement orbit

From 25 July 2014 to 15 January 2025, the Gaia space observatory performed high-precision measurements of nearly two billion stars from its Lissajous orbit around the L2 Lagrange point, 1.5 million km from Earth. After 10.5 years of groundbreaking observations, Gaia’s cold gas supply for attitude control has been depleted. On 27 March 2025, Gaia will leave its Lissajous orbit and transition into a stable heliocentric orbit. Soon after, the spacecraft will be passivated, with its instruments and transmitters switched off. While Gaia will no longer collect new data, its scientific mission is far from over! The team continues working on Gaia Data Release 4 (expected 2026) and the final legacy catalogue (to be published not before the end of 2030), ensuring that Gaia’s discoveries will shape astronomy for decades to come. This video visualises how Gaia leaves its Lissajous orbit and enters its final heliocentric orbit.
