The COMET( "COMmunities of 'ExperTs")  are like  “open circles of knowledge”.

For this reason, it is an excellent means of communication and way of distributing information, a showcase for you to present your developments without any major restrictions.

The COMET Chemical and Liquid Propulsion encompasses these major fields  (excluding launcher) :

  • Passivation of satellite propulsion systems: equipment, development, protocols.
  • New chemical propellants (green propellants) and, more widely, energetic materials, including pyrotechnical applications.
  • Long term stability of energetic materials: standards, methods, use.
  • New high-performance materials and associated processes (additive manufacturing, CVD, etc.)


There are many synergies with  PAPE COMET  (Electric propulsion) et PAAE COMET (Aerothermodynamics), mainly regardy following activities : 

  • De-orbiting and controlled re-entry
  • Passivation of fluid reservoirs (explosion of reservoir if not passivated).
  • Behaviour of materials at high temperatures.
  • Particular issues linked to certain components (titanium reservoir).
  • Shared physics (e.g.: plasma in electric propulsion and aerothermodynamics)
