New Space projects require “traditional” Space projects equipment-level testing. Typical testing campaigns for any kind of satellite or subsystem include:
Vibration, Shock Response Spectrum (SRS), Electromagnetic Compatibility (EMC) / EMI, Thermal vacuum (TVAC), TID, Other more specific tests needed for subsystems may include: Optical tests, Electrostatic Discharges (ESD), Materials tests (mechanical, electrical, cleanliness), Magnetic tests

The most relevant result of this work is that all tested samples passed satisfactory the test without relevant changes in the measured parameters, with the exception of one of the WG-EO switches which had a catastrophic failure, as it will be commented later. The pass/non-pass criteria were defined comparing the results of the electro-optical characterization after each test with the corresponding results for each parameter prior to the tests, taking into account the measurement uncertainty.

High thermal conductivity plastics filled with graphene have high thermal conductivity and good thermal stability, and their development prospects are very broad. Besides the thermal conductivity, graphene has other excellent properties, such as high strength, high electrical and optical properties, and is widely used in mobile devices, aerospace, and new energy batteries.
