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.

Kevin

Oh, my condolences! Still looking forward to hearing more from the university 
team!

All the best,
