Space GrainsThe aim of the Space Grains project is to study the dynamics and the statistical mechanics of an ensemble of particles that dissipates due to collisions. The experiments focus on clustering mechanisms, thermal fluctuations, convection, segregation and physical phenomena related to excited granular systems.
Coordination : E.Falcon and N.Vandewalle.

The Space Grains collaboration will use the Vip-Gran instrument during the 67th ESA Parabolic Flight Campaign, November 6 to November 16, 2017 at Novespace, Bordeaux (France)
The fourth parabolic flight campaign (PFC66) of the Vip-Gran instrument were performed in Bordeaux (France) in May 2017. We observe for the first time a transition for rods between a gas-like regime of to a cluster-like regime when the density … Continue reading
The Space Grains collaboration will use the Vip-Gran instrument during the 66th ESA Parabolic Flight Campaign, May 9 to May 19, 2017 at Novespace, Bordeaux (France)
The meeting is dedicated to prepare the 4th Parabolic Flight Campaign (ESA PFC66) of the Vip-Gran instrument. We will define the sets of parameters for the 3 flights of the PFC66 campaign scheduled from 9 to 20 May 2017. The … Continue reading
The goal was to defined the ESR (Experimental Scientific Requirements) for the ISS prototype of the Vip-Gran instrument. Various cells have been defined, among them: 3D and 2D dry cells, Wet cell, Sound cell, Shear cell…
After our presentation at ESTEC in January 2017, the ESA Programme Board approved the plan to proceed with no further delay with the development (phase δB/C) of the VIP-GRAN instrument for ISS as part of the ESA E3P SciSpace programme.
The third parabolic flight campaign of the Vip-Gran instrument were performed in Bordeaux (France) in November 2016. Granular convection, segregation for heterogeneous granular media, and quasi-elastic limit of a dissipative granular gas were studied.
