Ariane Next[2]—also known as SALTO (reusable strategic space launcher technologies and operations)[3]—is a future European Space Agency rocket being developed in the 2020s by ArianeGroup. This partially reusable launcher is planned to succeed Ariane 6, with an entry into service in the 2030s. The objective of the new launcher is to halve the launch costs compared with Ariane 6. The preferred architecture is that of the Falcon 9 rocket (a reusable first stage landing vertically with a common engine model for the two stages) while using an engine burning a mixture of liquid methane and liquid oxygen. The first technological demonstrators are under development.
