This proposal is intended to evaluate Final Frontier Design's IVA space suit in the relevant environment of microgravity. The testing would include comparative human-in-the-loop data of subject performance both in 1G and 0G, and both suited and unsuited. Data collected will include metabolic and biometric data, suited range of motion, and subject comfort. The flight profile includes 3 flights with 4 personnel and a total of 75 parabolas. This flight campaign would mark a significant step in TRL advancement for an innovative and high performance IVA space suit.
