Nyx Bikini

Maiden flight of Ariane 6. Failure of the auxiliary propulsion system precluded the third relight of the Vinci upper stage, causing the two reentry capsules and upper stage to be stranded in their 580-km circular orbit. Nine satellites, two reentry capsules, and five onboard experiments were launched. The ELaNa-48 mission, consisting of the two CURIE cubesats, was launched on this flight. The two CURIE cubesats were launched as a single spacecraft and separated in orbit (ESA Rideshares - Demo Flight).
