Mission: Incomplete 2 Understand environment Discover civilian uses Develop enabling technology Establish engineering standards Determine safe operational practices Enable routine use science economic benefit civil space national security NASA has no plans to extend activity in near space beyond ISS. Transition NASA’s experience base in near space to self- sustaining uses. Don’t repeat post- Apollo mistake.

A Near Space, Multi-purpose “City” Capture ISS heritage / lessons learned ‒Modules and nodes ‒Standard components, interfaces Enable near-term, value-added uses ‒Urban efficiencies ‒Serve all space-faring communities ‒Multiple, smaller business cases: B2B 6

Keeping It Real Realistic budget profile ‒Economies of scale ‒Incremental build ‒Flexible, situational expansion ‒Ubiquitous robotics, optionally manned Pragmatic, value-added uses Exit strategy for NASA 7

The System Vision Non-degrading orbit Serviceable, maintainable, upgradeable Free space platform with the ability to expand modularly without limit Initially: high earth orbit Ultimately: Lagrange points, deep space Structural focus with infrastructure Crystal-like geometry for growth Standard interfaces for new modules Multi-purpose for NASA, national security, and commercial uses 8

Commercial Key, Integrating Element National Security Technical capabilities in development Mission scenarios under consideration In-space robotics Autonomous rendezvous and docking In-space propulsion Ion propulsion Virtual presence Space solar power Deployable structures Inflatable structures Commercial logistics Manned lunar Manned Mars Lagrange / other staging Next generation, high-orbit assets Advanced telescopes Rapid repair / reconstitution Advanced deep space probes Commercial development of space Asteroids Affordable space NASA 10

A Modular Paradigm Thrust line for mobile spacecraft Open-ended for space structures Flat for surface structures 11 Modules Pressurized volumes Open trusses Docking portals / airlocks Utilities Nodes Nodes Mechanical connection Standard utility interfaces Shaped for architecture

Engineering for the Modular Paradigm Mission System Feasible, near term Multi-user utility Programmatically flexible High visibility, politically supportable Engineering Development Foundational architecture Envelope dimensions and capabilities Standardize interfaces Accommodate ubiquitous robotics Useful beyond / outside PISCES 12

The Engineering Challenge Develop and integrate independent elements for use across time hased xpandable eneral rchitecture for ystems sing egments No inherent limit on size An architecture that can apply to qualitatively different types of systems and missions Structures including systems, and subsystems Volumes, structures, and major subsystems that can be assembled as modular segments 13 Define / develop the modular paradigm

Why PEGASUS? Break cost/risk paradigm – Work within available resources – Greater system-level tolerance for risk Flexible: enables multiple missions – Human and robotic – Exploration and science – Orbital, deep space, and surface – Commercial, national security Robust: Reliable, affordable, long-term solution 14

PEGASUS Program Concept Harvest lessons from ISS, others Use PISCES mission set to identify needed functionalities Define architecture(s), envelopes, interfaces – Optimize for durable, system-focused approach – Growth potential including P 3 I LEO flight demo – Prototype for PISCES – Transition to commercial: business pathfinder for PISCES 15
