Could 2011 seal the Ariane rocket's fate?
The European Space Agency's lofty goals of an all-new rocket, partially or completely reusable, entering service around 2020 are falling by the wayside as its 2012 re-entry vehicle technologies demonstrator flight approaches.
Celle là particulier (et c'est dommage, c'est la première) je ne la saisi pas complétement... (falling by the wayside ?)
The FLPP goal now is to inform a decision on whether Ariane 5 is evolved or replaced. ESA has its "post-[Ariane 5] ECA" improvement plan that starts this year and continues until 2011. Pilchen expects an evolve-or-replace decision at the 2011 council. The post-ECA plan would lead to the improved Ariane 5 Mid-life Evolution (ME) that would enter service in 2016. Of the four FLPP demonstrators, Cryogenic Upper Stage Technologies (see box) and Solid Propulsion are relevant to Ariane 5 ME. Pilchen does not expect the High Thrust Engine to be used for the Mid-life Evolution.
Je laisse les commentaires à ceux qui savent et comprennent
