ESA ministers decided in 2014 to develop a new launcher family comprising Ariane 6 and Vega C, based on the existing Ariane 5 and Vega. The promise to secure autonomous access to space and reduce the price by a factor of 2 proved sufficiently compelling to secure ESA member states’ agreement to finance the development. At that time, I succeeded in placing environmental concerns and the possible development of reusability among the high-level requirements:
Maintain and ensure European launcher competence with a long-term perspective, including possibility of reusability/fly-back.
Ensure possibility to deorbit upper stage directly
Due to time and cost pressure, however, these aspects did not make it onto the agenda for Ariane 6 and Vega C. Yet in the meantime, the world has moved on and today’s situation requires that we re-assess the situation and identify the possible consequences.
In many discussions on ...
