Noctilucent cloud sampling by a multi-experiment payload.
Two multi-experiment payloads were launched into noctilucent cloud displays above Kiruna, Sweden, on the nights of July 31 and Aug. 1, 1971. The payloads were part of the continuing Pandora II cosmic dust collection series and included: (1) Pandora 2 dust collection with in-flight shadowing photoele...
