摘要

The effect of hypervelocity impact on spacecraft materials and structures is a subject that has received extensive attention in the context of space debris in Earth orbit. Motivated by forthcoming missions to small bodies and recent results on hypervelocity impacts on solar panels returned to Earth from the Hubble Space Telescope, I consider the damage to spacecraft solar arrays during the spacecraft flybys of comet Halley in 1986 and show that the performance loss seems to be related to the fluence of the smallest impactors and is around three orders of magnitude higher than would be expected from crater-area considerations. The nonlinearity and the magnitude of the solar array degradation with dust fluence are consistent with open-circuit failures of solar cell strings, possibly by impacts on or near cell interconnects.
