Z Suits • NASA is developing the next generation Space Suit for future missions including Mars Exploration – ILC delivered Z 1 – We will deliver Z 2 – Z 3 planned 2011 2014 2018 • Z 1 and Z 2 trace their history to prior suit technology demonstrators ILC Dover Proprietary Information 2

Types of Space Suits • Intravehicular Activity (IVA) – Launch, entry, abort – Contingency suit • Cabin depressurization • Cabin smoke – “Self-rescue” mobility • Pad abort • Egress after landing • ILC Pathfinder Suit shown ILC Dover Proprietary Information 3

Types of Space Suits • Microgravity Extravehicular Activity (EVA) – ISS Extravehicular Mobility Unit • • Environmental protection Ability to do work No walking-type locomotion Feet/legs provide anchor points – React loads from doing work with arms – Commercial EVA Suit developed • Limited walking required ILC Dover Proprietary Information 4

Types of Space Suits • Planetary Surface EVA – Environmental protection – Ability to do work – Locomotion – Dust protection – Lower body used to do work • Apollo suit: – Still the only suit used in planetary exploration ILC Dover Proprietary Information 5

Z Suit Series Overview Z 1 - 2011 Z 2 - 2014 Z 3 – 2018+ ILC Dover Proprietary Information 6

Z Suit Strategy • Purpose – Provide the most capable suit architecture to support challenging mission requirements, largely represented in a Mars mission, that is applicable to any surface, and adaptable for microgravity • Methodology – Develop, test, and understand the capabilities and limitations of each prototype mobility joint system and at assembly level • Goal – Flight fidelity suit system in a vacuum chamber by 2018 (Z 3 Suit, PLSS, avionics) ILC Dover Proprietary Information 7

Z Suit Approach • Mobility is key – As near nude body as possible – Increase crew productivity – Decrease mental and physical fatigue • Safety is critical – Reduced mechanisms and likelihood of use related injury – Increase structural margins • Weight is important – Reduce the weight for vehicle launch mass and EVA on back • Durability is required – Assuming 3 year Mars mission – Minimize maintenance ILC Dover Proprietary Information 8

Z Suit Key Features • Rear Entry Suit • Test bed for suitport hardware concept • Incorporates enhancements from previous ILC suit builds • Each version builds on previous (Z 1, Z 2, Z 3) • Planetary walking suit – mobility • 8. 3 psi versus 4. 3 psi ISS EMU • Each version raises TRL ILC Dover Proprietary Information 9

Z 1 Space Suit • Z 1 Suit features – Walking capability; different gravity fields • Ranging from Mars to microgravity – Rear entry • Improve donning; safety – Suit port compatible • Don pressurized suit; keep dust outside – Higher (8. 3 psi) pressure • address bends risk; increase efficiency – Soft upper torso, brief • Lower cost; weight (126#) ILC Dover Proprietary Information 10

Z 1 Precursers Original ILC I-Suit (I for ILC) - being tested on zero-G flight - Circa 1998 - Soft upper torso; brief - 8 psi - Bottom entry - Lightweight (77#) Rear Entry I-Suit (REI-Suit) - being tested at Desert Rats - Circa 2005 - Soft upper torso; brief - 8 psi - Rear Entry - Lightweight (84#) ILC Dover Proprietary Information 11

Z 1 Space Suit • Accolades: – Z 1 named one of Time Magazine’s Best Inventions of 2012 – The Z-1 space suit provides go-anywhere garb featuring more-flexible joints, …and a hatch on the back that allows the suit to dock with a portal on a spacecraft or rover so an astronaut can crawl through without letting dust in or air out. ILC Dover Proprietary Information 12

Z 2 Precursors • Mark III Zero Prebreathe Suit (ZPS) – Original Mk. III delivered to NASA 1990 – Modified Mk. III at Desert Rats 2005 – Hard upper torso, brief; hybrid shoulder – 8. 3 psi ILC Dover Proprietary Information 13

Z 1 and Z 2 Differences • Soft versus hard elements – Z 1 has soft upper torso, brief – Z 2 has these elements made of advanced composites – Intent is to increase durability • TRL – Z 1 undergoing Earth atmosphere testing – Z 2 will undergo human vacuum testing • Increased Z 2 requirements, goals, testing – Kick loads – Anti-microbial material use – Range of motion testing at 8. 3 psi • Mass – Z 1, 126# – Z 2, 140# goal (with Suit Port Interface Plate) ILC Dover Proprietary Information 14
