Ariane 6 completes first flight to geostationary orbit
What happened
Arianespace launched an Ariane 62 configuration from Kourou, French Guiana carrying Eumetsat's MTG-I2 weather satellite — Ariane 6's fourth flight of 2026 and its first-ever mission to geostationary transfer orbit (all prior flights were LEO/SSO or direct-to-GEO-adjacent institutional payloads on the heavier 64 config, per Arianespace's own mission list). Liftoff was 17:11 local time (20:11 UTC), inside the pre-announced 20:10-22:40 UTC window.
Read-across for SES
Launch bottleneck / launch economics thread — Ariane 6 is Europe's flagship non-SpaceX launcher and IRIS²/SpaceRISE's primary planned vehicle for the 2029 first launches SES is financially committed to (up to €1.35bn). A clean first GEO mission is a concrete reliability proof point at a moment the vehicle's own Block 3/ICARUS upgrade was just shelved (confirmed 08-20) — it demonstrates the un-upgraded Ariane 62/64 baseline can still expand its mission envelope, which matters for SES's launch-supply hedge against SpaceX dependence.
