The countdown is underway for VV27. MicroCarb and CO3D are completing their ground preparations.

The CO3D and MicroCarb satellites have arrived in French Guiana for their launch on board Vega-C, scheduled for 25 July from Europe’s Spaceport. Check out a photo gallery of the mission preparations.

Europe’s Spaceport is gearing up for a new launch: on 25 July 2025, at 23:03 local time. Vega-C will place CO3D satellite and MicroCarb satellite into orbit.

The launch sites include all the infrastructure needed on the ground to carry out assembly and integration operations for the various components of a launch vehicle, as well as for the launch itself.

With just a few hours to go before the launch of the Biomass mission from Europe’s Spaceport in French Guiana, here is a look back at the key stages in the preparation of this unique satellite.

On Tuesday, 29 April 2025, at 6:15 a.m., as the sky over Kourou was bathed in the first light of dawn, the Vega C rocket successfully lifted off from Europe's Spaceport in French Guiana.

On April 29, 2025, Vega-C will launch Biomass, the European Space Agency’s Earth Explorer satellite from Europe spaceport at 6:15 a.m. local time (09:15 a.m. UTC, 11:15 a.m. CEST).

The hot-fire test of the new P160C motor, intended for Ariane 6, Vega-C, and Vega-E, is scheduled for 24 April between noon and 4 p.m. It will be conducted at Europe’s Spaceport on the solid booster test bench (BEAP).

On April 29, 2025, Vega-C will launch Biomass satellite from Europe’s Spaceport in French Guiana at 6:15 a.m. local time (09:15 a.m. UTC, 11:15 a.m. CEST).

ESA’s Biomass satellite has arrived at Europe’s spaceport, where it will prepare for a launch scheduled for late April onboard a Vega-C rocket.
