8 Main Features: Additional thermal and debris protection (arms, legs, and chest) Portable life support system (PLSS): Drinking H2O, O2, CO2 scrubbers, and cooling system Nominal pressure of 8 PSI Nominal operating time is 240 minutes Picture by Stephanie Johnston Specifications Mass*: 70 kg Volume: 0.20 m 3 Energy: 50 W *Note: Mass of PLSS is 20 kg

9 Uses lines of non-extension to create a mechanical counter pressure suit. Problem: Suits have to fit perfectly (must be individually made). Problem: Suits are not modular so they cannot be modified for a second person. Thermal protection, extra layers for dust/rock protection, and other life support issues have not been addressed yet. Our crew will be relying on rovers most EVAs. Image Copyright of 2005 Volker Steger / Science Photo Library Image from 2008 Silver BioSuit Mock-up Return to HF Title
