“The directive I am signing today will refocus America’s space program on human exploration and discovery. It marks a first step in returning American astronauts to the Moon for the first time since 1972, for long-term exploration and use. This time, we will not only plant our flag and leave our footprints — we will establish a foundation for an eventual mission to Mars, and perhaps someday, worlds beyond.”
-President Donald Trump
In December 2017, President Donald J. Trump gave NASA a new direction, telling the agency to work with international and commercial partners to refocus exploration efforts on the moon, with an eye to eventually going on to Mars and even beyond. As stated in Space Policy Directive-1, “The NASA Administrator shall, ‘Lead an innovative and sustainable program of exploration with commercial and international partners to enable human expansion across the solar system and to bring back to Earth new knowledge and opportunities. Beginning with missions beyond low-Earth orbit, the United States will lead the return of humans to the Moon for long-term exploration and utilization, followed by human missions to Mars and other destinations.’ ”
The Exploration Campaign is a national and agency effort focused on three core domains: low Earth orbit; lunar orbit and surface; and Mars and other deep space objectives. The campaign has four strategic goals:
- Transition U.S. human spaceflight in low-Earth orbit to commercial operations, which support NASA and the needs of an emerging private sector market.
- Extend long-duration U.S. human spaceflight operations to lunar orbit.
- Enable long-term robotic exploration of the Moon.
- Enable human exploration of the Moon as preparation for human missions to Mars and deeper into the solar system.
Each focus area has a set of objectives:
Low-Earth orbit objectives:
- End direct support to ISS by 2025 while stimulating commercial industry to develop capabilities NASA and private sector can utilize and meet NASA’s exploration risk mitigation and science requirements.
- Starting in 2018, increase the breadth and depth of commercial and international LEO activities. Specifically:
- Offer to expand the International Space Station partnerships to new nations, including new international astronaut visits.
- Based on inputs from current ISS partners, commercial, stakeholders to shape the plan for the transition of LEO activities from direct government funding to a commercial basis on independent commercial platforms or a non-NASA operating model for some form of the ISS by 2025.
- Expand public-private partnerships to develop and demonstrate technologies and capabilities to enable new commercial space products and services.
Lunar orbit and surface objective:
- Establish a long-term presence in the vicinity of and on the Moon, realizing science and human exploration advancement, while also enabling other National and commercial goals.
Lunar orbit objectives:
- Conduct the uncrewed SLS/Orion first flight in 2020 to the lunar vicinity.
- Conduct a crewed flight sending Americans around the Moon in 2023.
- Establish a human tended lunar orbiting platform for crews to visit from earth, to transit to and from the lunar surface, and to depart to and return from Mars.
- Develop the Lunar Orbital Platform-Gateway that, at a minimum:
- Emplaces a power-propulsion (communications) element (PPE) around the Moon by 2022. The development of this first strategic element will incorporate innovative procurement and partnering strategies, capitalize on US commercial communication satellite capabilities, demonstrate high power solar electric propulsion technology, and provide the critical functionality for the rest of the cislunar orbital platform.
- Performs science and technology activities, for example, lunar sample return and the operation of lunar robotic and in-space systems.
Lunar surface objectives:
- Orchestrate a lunar robotics campaign with a focus on growing a commercial base of partnerships and activity that can support U.S. science, technology, and exploration objectives. Include international participation, where appropriate.
- Support a small commercial lander initiative with an initial strategic presence on the Moon no later than 2020.
- Develop (a mid-to-large scale lander initiative working toward human-rated lander. This initiative will focus on enabling commercial and international partnerships.
- Support an early science and technology initiative that includes Lunar CubeSats, a Virtual Lunar Institute and other activities.
- Further enable and nurture entrepreneurial and commercial market forces that will define long-term human exploration and exploitation of the lunar surface.
- Aggressively characterize lunar resources so that their potential future exploitation can be addressed.
Mars and other deep space objectives
- Maintain and grow U.S. leadership at Mars with a rover in 2020, as a first step of a sample-return strategy, searching for past life and demonstrating oxygen production. Use this mission as a building block for a subsequent round-trip robotic mission with the historic first launch off another planet and sample return through the lunar gateway and the broader exploration architecture.
- Prioritize and guide investments and partnerships in long-pole technology areas and resource characterization needed for the exploration of Mars and other deep space destinations.
- Develop standards for human long-duration deep space transportation vehicles.
- Establish NASA roles as architect, systems integrator, and expedition lead.
- Define an open architecture that meets National objectives, enables its partners, and where appropriate, interfaces with other partner and entities’ goals and objectives
- Relatedly, develop system interface standards and requirements designed, where appropriate, for commercial and international collaboration
- Seek and develop substantial new international, commercial, and inter-agency partnerships, leveraging current International Space Station (ISS) partnerships and building new cooperative ventures for exploration.
- Expand international, commercial, and inter-Agency partnerships on the ISS to provide a proving ground and incubator for new partners while helping to offset the costs of operations.
- Expand International, commercial, and inter-Agency opportunities for research and technology development to offset the costs of operations.
- Continue US Government research and technology development necessary for the broader Lunar Exploration Campaign.
- Seek potential incentives that could enable broader participation by providing commercial transportation and access for both cargo and crew to the ISS for new users of space.
- Interact with and leverage where appropriate lunar orbital and surface activities outside of NASA (e.g. depots, on-orbit assembly, inter-nodal servicing, and scientific assets and facilities).
