| Term: | Susceptibility |
| Definition: |
The response of a material or substance to a change in conditions. In the spacecraft case, this may be characterised by e.g. SEP susceptibility: Rate of destructive and non-destructive SEEs in specified components under specified shielding levels due to an SEP event Surface charging susceptibility: Surface potentials of defined materials due to ambient plasma Internal charging susceptibility: Internal charging levels of specified dielectric components under specified shielding Degradation due to radiation susceptibility: Dose and NIEL degradation of specified components under specified shielding (including solar cell degradation) Satellite attitude change susceptibility: Deviations in magnetic torque Satellite orbit change susceptibility: Orbit alteration due to drag enhancement in LEO EM interference susceptibility: Telecommunications interference (TBC) |
