ICAPS (Interactions in Cosmic and Atmospheric Particle Systems) is a new international microgravity research program for the International Space Station (ISS).
Interactions of solid and liquid particles with other particles, with gas, and with light will be investigated, including aggregation phenomena, light scattering properties, evaporation and condensation cycles, and phoretic effects.
ICAPS is subdivided into six Central Research Topics (CRT):
CRT1: Aerosol Microphysics
CRT2: Phoretic Effects
CRT3: Dust Agglomeration
CRT4: Simulated Regoliths
CRT5: Light Scattering (exp.)
CRT6: Light Scattering (theor.)
Compared to several previous attempts to build a multi-user microgravity facility for particle experiments in microgravity, ICAPS is the most modern approach and was judged scientifically "outstanding" by the international peer reviewers. Preparatory laboratory work is in progress. ICAPS is sponsored by the European Space Agency (ESA) and the national space agencies of the team members' countries.
ICAPS will be realized within ESA’s IMPACT laboratory (International Microgravity Plasma, Aerosol and Cosmic dust Twin laboratory).
