2. ILC Dover Proprietary Information Z Suits NASA is developing the next generation Space Suit for future missions including Mars Exploration –ILC delivered Z1 2011 –We will deliver Z22014 –Z3 planned 2018 Z1 and Z2 trace their history to prior suit technology demonstrators 2

3. ILC Dover Proprietary Information 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 3

4. ILC Dover Proprietary Information 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 4

5. ILC Dover Proprietary Information 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 5

6. ILC Dover Proprietary Information Z Suit Series Overview 6

7. ILC Dover Proprietary Information 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 (Z3 Suit, PLSS, avionics) 7

8. ILC Dover Proprietary Information 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 8

9. ILC Dover Proprietary Information 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 (Z1, Z2, Z3) Planetary walking suit – mobility 8.3 psi versus 4.3 psi ISS EMU Each version raises TRL 9

10. ILC Dover Proprietary Information Z1 Space Suit Z1 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 (8.3psi) pressure address bends risk; increase efficiency –Soft upper torso, brief Lower cost; weight (126#) 10

11. ILC Dover Proprietary Information Z1 Precursers 11 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#)

12. ILC Dover Proprietary Information Z1 Space Suit Accolades: –Z1 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. 12

13. ILC Dover Proprietary Information Z2 Precursors Mark III Zero Pre- breathe Suit (ZPS) –Original MkIII delivered to NASA 1990 –Modified MkIII at Desert Rats 2005 –Hard upper torso, brief; hybrid shoulder –8.3 psi 13

14. ILC Dover Proprietary Information Z1 and Z2 Differences Soft versus hard elements –Z1 has soft upper torso, brief –Z2 has these elements made of advanced composites –Intent is to increase durability TRL –Z1 undergoing Earth atmosphere testing –Z2 will undergo human vacuum testing Increased Z2 requirements, goals, testing –Kick loads –Anti-microbial material use –Range of motion testing at 8.3 psi Mass –Z1, 126# –Z2, 140# goal (with Suit Port Interface Plate) 14
