8.2.4 Prevention of Photocathode Damage

  Ideal solutions to our humidity problem (§6.1.3) would be either to devise a way to maintain the N2 purge up to the launch time or configure the payload so that it could be maintained under vacuum. Unfortunately, both options are complex and costly. Presently, our intention is to try to seal the payload aperture doors as much as possible and then install a plastic flap over the vent. This flap should impede the infusion of air before launch, but it should not significantly compromise the decompression during the ascent.
