Hi Fabien - I echo Marcus' condolences and am sorry to hear that the sad news that the flight was terminated.
I am hopeful your team will be able to launch a new CASSA-SAT payload on an upcoming mission opportunity. Still, many congratulations to the CASSA-SAT team for the payload development successes - that is a huge accomplishment and is not diminished.
