For your Consideration: NASA Engineer Owned STS-87 Lewis Experiments On USMP-4 Handouts Stickers This is an original handout from The Fourth Unite States Microgravity Payload (USMP-4). The folder contains document handouts and stickers for most of the experiments done on STS-87. Almost everything is in excellent condition. The sticker from the ?OARE? experiment has a bend and separation on one corner. The main handout has some slight wear at the top from storage as it is slightly taller than the folder. Also included is an original patch for the ?Bismuth Tin Solidification Experiment.? All of the Stickers and Patch are unused. Please see pictures for condition.
