National Aeronautics and Space Administration A New Space Enterprise Presentation to the Planetary Protection Subcommittee of the NAC Dr. Laurie Leshin Deputy Associate Administrator NASA Exploration Systems Mission Directorate August 5, 2010
The New Path for Human Space Exploration • The FY 2011 budget request challenges NASA to embark on a new human space exploration program that is sustainable and affordable • The budget balances investments in future human spaceflight systems with obtaining key knowledge about future destinations and demonstrating critical enabling technologies for human spaceflight and exploration, including: – Research & development of heavy-lift and propulsion engines and other key technologies – Technology development and demonstrations to reduce cost and prove required capabilities for future human exploration – Exploration precursor robotic missions to multiple destinations to cost- effectively scout human exploration targets and identify hazards and resources for future human exploration – Increased investment in Human Research to prepare for long journeys beyond Earth – Expanded efforts to develop U. S. commercial human spaceflight capabilities, making space travel more accessible and affordable • The FY 2011 budget will continue the development of the human crew capsule, an Orion-derived vehicle that will serve as an emergency return vehicle from ISS, and will be part of the technological foundation for advanced spacecraft to be used in future deep space missions 2

Changing Technology Development Design and Development of Heavy-Lift and In-space capabilities Human Exploration Missions to Solar System Destinations 3
What is the Strategy and Destination? • The future human spaceflight program will build through a steady sequence of achievements, from a set of crewed flights to test and prove systems required for exploration beyond Low-Earth orbit (LEO) early in the next decade, to a near-Earth object (NEO) mission in 2025, to missions to Mars’ environs by mid-2030 s, followed by landing on Mars • This approach builds experience and capability through time, results in successive “firsts” (much like the Mercury and Gemini approach) and allows the human spaceflight systems to be developed serially rather than concurrently, making the endeavor affordable to the taxpayer • Although we cannot provide a date with certainty for the first human landing on Mars, we can identify essential capabilities needed for such a mission. These are reflected in the programs within this budget request. – They are capabilities that have been recommended consistently for over two decades in national level reports of committees addressing future human space exploration – They are the near-term steps NASA must take to create the new knowledge and capabilities required for humans to venture beyond LEO to stay 4
New Program Planning Underway • NASA has established initial plans for the programs announced in the FY 2011 Budget Request – A “point of departure” has been established which will continue to be refined • Allows NASA to make informed decisions and establish program objectives and expectations – Provides a starting point for engagement with outside organizations (international, industry, academia, and other government agencies) – Determine capabilities needed and identify technology development and demonstration cost, schedule and associated risks – Enables high level integration across programs to develop full framework of future human exploration – Specific launch dates and missions are likely to change to reflect the addition of Emergency Rescue Vehicle, updated priorities, and new information from NASA’s space partners • These investments are being integrated into a long-term plan and decision framework by the Human Exploration Framework Team (HEFT) 5

PRM mission. 7

Thoughts on Planetary Protection Issues – ESMD understands the importance of incorporating Planetary Protection requirements into new Programs early – such conversations have already begun • Objectives for NEO missions being considered at Workshop next week – New Programs provide near term opportunities to continue research related to Planetary Protection, including considering new modes of remote operation – Increased focus on NEOs/asteroids as targets necessitate new Planetary Protection considerations • Will need to work specific requirements as individual targets are considered and precursor missions planned • Human Mars surface exploration will continue to figure in future planning but is not subject of intense near-term discussions wrt Planetary Protection 17
ESMD: Blazing a Trail Into the Solar System • NASA’s human spaceflight program seeks to extend human presence throughout the solar system • The President's FY 2011 Budget Request takes a new approach to this goal, focusing on capabilities that will allow us to reach multiple destinations, including the Moon, Asteroids, and Mars and its moons • The investments seek to create the new knowledge and capabilities required for humans to venture beyond low Earth orbit to stay • Approach expands alternatives available for human exploration, currently limited by lack of strategic investment in technology development over past decades www. nasa. gov/exploration 18
