PISCES Settling the Near Space Frontier Doris Hamill NASA Langley Research Center FISO Telecon June 5, 2013
Mission: Incomplete 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. • 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
What is Near Space? ? asteroid moon Mars
Near-term, Value-Added Uses Solving the launch cost problem will not remove all the inhibitors to self-sustaining use of near space. Infrastructure
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
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
The System Vision Free space platform with the ability to expand modularly without limit Non-degrading orbit Serviceable, maintainable, upgradeable P ermanent IS Initially: high earth orbit Ultimately: Lagrange points, deep space n pace C enter Structural focus with infrastructure E Crystal-like geometry for growth Standard interfaces for new modules for xpandable S Multi-purpose for NASA, national security, and commercial uses ervices
Key, Integrating Element Technical capabilities in development Mission scenarios under consideration In-space robotics NASA Inflatable structures Asteroids Manned lunar Lagrange / other staging Commercial logistics Manned Mars Deployable structures Advanced telescopes Autonomous rendezvous and docking Advanced deep space probes PISCES National Security Virtual presence Rapid repair / reconstitution Ion propulsion Next generation, high-orbit assets In-space propulsion Affordable space Space solar power Commercial Commercial development of space
A Modular Paradigm Modules Pressurized volumes Open trusses Docking portals / airlocks Utilities Nodes Mechanical connection Standard utility interfaces Shaped for architecture Open-ended for space structures Thrust line for mobile spacecraft Flat for surface structures
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 PISCES PEGASUS
The Engineering Challenge Define / develop the modular paradigm P Develop and integrate independent elements for use across time hased E xpandable No inherent limit on size G An architecture that can apply to qualitatively different types of systems and missions eneral A rchitecture S Structures including systems, and subsystems for ystems U Volumes, structures, and major subsystems that can be assembled as modular segments sing S egments
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
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 P3I • LEO flight demo • Prototype for PISCES • Transition to commercial: business pathfinder for PISCES
Exit Strategy for NASA P3I time NASA PEGASUS PISCES Municipality Operate infra-structure Design Develop Establish operations Commercial Service Providers National Security Community Design, develop, deploy, operate mission modules NASA Exploration NASA Science Commercial Users
