NASA’s SPACE EXPLORATION PLANNING: THE ASTEROID MISSION AND THE STEP-WISE PATH TO MARS Kathleen C. Laurini NASA, Johnson Space Center, Houston, TX, USA, [email protected] Michele M. Gates NASA, Headquarters, Washington, DC, USA, [email protected] Within the U.S. space policy framework, NASA continues to advance its space exploration programs and plans to remain a world leader and valuable partner in space exploration. NASA’s programs reflect the importance of human space exploration in the U.S. by focusing on the foundational capabilities and technologies which will ensure government investments continue to drive innovation and enable exciting missions as part of a step-wise path to Mars. NASA is focusing on developing these initial capabilities while collaboratively working with international partners to define a technically feasible and programmatically implementable strategy for deep space exploration. This paper summarizes this work and how NASA’s approach to capability development enables a step-wise path to human exploration of Mars, with missions along the way providing the opportunity to infuse new technologies, advance capabilities, learn to manage the risks of operations in deep space while using the presence of the crew to explore, discover and inspire. NASA is laying the groundwork for the partnerships necessary to explore beyond low-Earth orbit (LEO). In addition to the International Space Station enabling important learning related to long duration mission human health and performance, the heavy lift launcher Space Launch System (SLS) and the Orion crew vehicle are foundational capabilities under development for human missions beyond LEO. Initial Orion and SLS vehicles will enable near-term missions in the lunar vicinity and demonstrate capabilities and operations necessary for exploration missions further away from the relative safety of LEO. These missions also enable exploration of a near-Earth asteroid and the Moon, allowing the presence of the crew to engage the public in ways that further increase value to people on Earth. International and public-private partnerships will enable these early missions and ensure that human space exploration proceeds in a sustainable manner. This paper describes how the Asteroid Redirect Mission fits into the long term international context described in the Global Exploration Roadmap, released by space agencies participating in the International Space Exploration Coordination Group (August 2013). NASA welcomed the contribution of the January 2014 International Space Exploration Forum. The meeting of government representatives demonstrated the importance of international partnerships in exploring space and welcomed the work of space agencies on the Global Exploration Roadmap. INTRODUCTION central to NASA’s space exploration strategy. The NASA continues to advance its space exploration long-term goal of human exploration of Mars informs programs and plans to remain a world leader and robotic mission planning, technology development valuable partner in space exploration. NASA’s priorities, requirements for near-term human programs reflect the U.S. commitment to human spaceflight capabilities, and activities onboard the space exploration by focusing on the foundational International Space Station (ISS). Orion and Space capabilities and technologies which will ensure Launch System (SLS) are currently under government investments continue to drive innovation development, with Orion Exploration Flight Test-1 and enable exciting missions as part of a step-wise scheduled for this December. Technology path to Mars. As evidenced by the Global advancements in high power, long life solar electric Exploration Roadmap, Mars is the collective propulsion open new approaches for human international horizon destination (Ref 1).
