LESIA - Observatoire de Paris

Test facilities

Monday 7 January 2019, by Jérôme Parisot


The important heritage of activities at LESIA has allowed the MESPAL group to collect a wide range of test facilities. These are proposed for LESIA projects and by extension proposed in the frame of GIS-PARADISE of INSU (pooling & sharing of facilities). The different instruments are describred here below.


  • SimEnOm
    Thermal vacuum chamber for space environment simulation, 1m3, temperature range: 80K-370K (cooling with liquid nitrogen).
