Reactions to the threat

The Megha-Tropiques team members organize a reaction to the threat :
–    Indian colleagues are informed of the problem and alert ISRO
–    two petitions (one National, in French, and one international, in English) are signed by numerous scientists : see texts and signatures here
–    letters (and petitions) are addressed to different authorities (CNES direction, CNRS, a Commission auditing CNES, Minister of Research, Deputies in the National Assembly)
