PARIS (CNES PR) — With a view to preparing for the future, the development of new dense and energetic propellants (HEDM) is one of the avenues to be explored to optimize the performance of launchers.

PARIS (CNES PR) — What will the launcher look like the day after tomorrow? It is far too early to tell, but CNES is already working to imagine the disruptive technologies that will make it fly.

In the field of launchers, you have to know how to look far ahead. While the qualification of Ariane 6 has entered its final phases, its successor Ariane Next is envisaged for the 2030s, and reflections for the post-2040 are well underway with the Ariane Ultimate project . At this stage, it is still only a concept, that is to say a pool of new technologies which are in an embryonic state but which we want to make mature by this time, in order to develop a launcher that must be carbon neutral, fully reusable and at almost zero marginal launch cost. It is also a question of projecting on the new uses of space in the coming decades as we can imagine them on this horizon: for example the need for high speeds to reach the low orbits which could serve as hubs of exchange towards the Moon or towards Mars.
