Arianespace Prepares to Launch the First Ariane 6 Space Rocket with P160C Boosters for an Amazon Leo Mission
The launch cadence of the European space rocket Ariane 6 by Arianespace is gradually increasing. The latest mission was completed at the end of April, successfully placing 32 satellites into orbit for the Amazon Leo constellation (which aims to compete with SpaceX's Starlink). Thanks to institutional and commercial missions, the heavy launcher is carving out its space in the launch market.
Thanks to the first mission for Amazon Leo, which took place in February of this year, we witnessed the debut of version 64 of Ariane 6. This model features four solid-state side boosters called P120C, manufactured by the Italian company Avio. The evolution of the European space rocket is not yet at an end. Although no additional side boosters are planned, Arianespace will debut the more powerful P160C with the next launch.
Ariane 6 with P160C Boosters Ready for Debut
At the end of February, there was discussion about the possibility of debuting the P160C boosters this summer, and the plans seem to be on track. Mission VA269 or Leo Europe 3 (LE-03) will be the first to feature four P160C side boosters, further enhancing overall performance without substantial modifications to the vehicle's design. Testing has been ongoing for some time, and we will see the results in the coming weeks.
It's interesting to note that Amazon Leo might see the debut of another launch vehicle soon. ULA is completing its Atlas V rockets and will then fully transition to Vulcan Centaur, which continues to suffer from reliability issues with the side boosters produced by Northrop Grumman. Mission LA-07 will be one of the last Atlas V launches, expected to take place around 6:30 PM on May 29.
Following that, ULA will launch the Leo Vulcan 1 (LV-01), the first with Vulcan Centaur. The rocket will place a remarkable 38 satellites into orbit simultaneously, setting a new record for the Amazon constellation. Looking further ahead, Blue Origin's New Glenn is set to debut, promising even better performance.
In general, it is expected that by the end of the year, Amazon Leo could start being available to its first customers (initially corporate-type). The gap with Starlink is still quite significant, but it seems that the production of units is occurring in numbers that could ensure Amazon a high overall launch cadence, recovering some of the disadvantage (while SpaceX is focusing on the new third-generation Starlinks to further enhance performance, but we will have to wait for the operational readiness of Starship).
