Scientific Assemblies

COSPAR Scientific Assemblies are held every two years (even numbered years). These events attract currently between 2000 and 3000 participants. National COSPAR Committees interested in organizing a Scientific Assembly are invited to contact the COSPAR Secretariat (aaron.janofsky – at – cosparhq.cnes.fr) for further details.  Please note that expressions of interest and bids will only be accepted from appropriate national scientific institutional authorities.  General Guidelines for Organizing COSPAR Scientific AssembliesCOSPAR Assembly Requirements Document.
