The final countdown has begun: four years late, the Ariane 6 rocket is set to blast off for the first time on Tuesday above the Guyanese jungle, carrying with it Europe’s hopes of regaining independent access to space.
At 3:00 p.m. (8:00 p.m. HB), the two boosters and the main stage engine will ignite for liftoff. A four-hour launch window is planned, in case an anomaly is detected or unpredictable weather arises. At first light at the Guiana Space Center (CSG) in Kourou, the mobile gantry, which houses the rocket, will be moved 100 meters, revealing the 56-meter behemoth on its launch pad.
Then at 10:00 local time, the tanks will be filled with the liquid oxygen and hydrogen that power the Vulcain engine. From this point onwards, any anomaly requiring physical intervention would necessitate emptying the tanks, leading to a 48-hour delay in the launch, explains Jean-Michel Rizzi, head of the Ariane 6 launch base for the European Space Agency (ESA).
Decided in 2014, Ariane 6 will be able to launch satellites into geostationary orbit, at an altitude of 36,000 kilometers, similar to its predecessor Ariane 5, as well as deploy constellations into orbit a few hundred kilometers from Earth.
A bit of Belgian know-how
For its maiden flight, Ariane 6 will carry 17 “passengers” on board: 11 university micro-satellites, various experiments and two atmospheric re-entry capsules, intended to prepare the space freighter that is being developed by the Europeans for resupplying the space stations.
The rocket will also carry some Belgian technological innovations. During this inaugural flight, equipment manufactured by the Walloon aerospace company Sonaca will be on board the launcher for testing. This device, developed in collaboration with CRM and Walopt, is designed to enhance thermal management of the electronics by acting as damping, the company explained in a press release on Tuesday.
A successful flight will mark Europe’s “return” to the space scene, according to ESA’s head of space transportation, Toni Tolker-Nielsen. Since the last Ariane 5 flight a year ago, Europeans have not been able to launch a satellite into orbit independently: since the invasion of Ukraine, they no longer have access to the Russian Soyuz medium launcher, and the Vega-C rocket has been grounded since the end of 2022 following an accident. However, according to Tolker-Nielsen, it will then be necessary to successfully increase the launch rate, with another flight scheduled for the end of the year, six planned for 2025 and eight the following year.

At 3:00 p.m. (8:00 p.m. HB), the two boosters and the main stage engine will ignite for liftoff. In the event of an anomaly detected up to the last moment or unpredictable weather, a four-hour launch window is planned. At first light at the Guiana Space Center (CSG) in Kourou, the mobile gantry, a vast cathedral that houses the rocket, must be moved 100 meters, revealing the 56-meter behemoth on its launch pad.
