Research in Biological and Physical Sciences in Space (BPS) has enabled the United States to be a trailblazer for both human and robotic space exploration, while sparking a wealth of technological advances to help society.

The United States has an unprecedented opportunity to lead the way to the Moon and Mars, but to do so, the nation must also be at the forefront of innovation for science and technology in space. However, despite more experiments being performed in space than ever before, NASA’s BPS program is severely underfunded compared to investments made during the space shuttle era.

If the United States wants to maintain its leadership role for the next generation of space science and exploration, funding for BPS research will have to increase tenfold before the end of the decade. This level of funding is necessary to support a robust and resilient program that can meet the nation’s needs.

Key Scientific Questions Focusing the Next Decade of BPS Research

Prioritizing eleven key scientific questions, spanning three major themes of research in and about the space environment, will position the nation to travel and prosper in space sustainably, all while returning benefits to Earth.

Adapting to Space
Life in space operates differently than life on Earth. It is critical to understand how the space environment impacts human beings as well as the plants and microbes that will be part of future habitat systems.

Advancing Space Exploration and Supporting the BPS Community

  • NASA responded to the 2011 BPS Decadal Survey by standing up what is now the Biological and Physical Science Division (BPS) within the Science Mission Directorate. As a result, the scientific community in these important and diverse fields has begun to be rebuilt. However, much work remains to establish a healthy and sustainable BPS community with resources commensurate with its long-term scientific and technological mission.

    A robust and resilient BPS program requires:

    • a healthy and regular cadence of proposal calls and grant funding that are consistent with sustaining a diverse and productive BPS community over the course of the next decade and beyond
    • broadened and more inclusive participation in the U.S. BPS community, including diversity of both scientific expertise and by lived socioeconomic experience
    • a total science budget sufficient to meet current national needs and international competitor/collaborator challenges
    • interactions with other U.S. government and non-U.S. space agencies necessary for optimal BPS community productivity in science and technology development
    • significant awareness and collaboration with emerging commercial space science platforms and activities

  • Access to spaceflight and the wide range of platforms where BPS research is undertaken—including remote environments on Earth, suborbital flights, Earth orbit, the Moon, and Mars— is essential for building a strong BPS program. NASA BPS should work with the Space Technology Mission Directorate to coordinate funding opportunities and provide access to space platforms, particularly for research that informs technology development for space exploration.

    The International Space Station has been a critical platform for BPS research, but it is nearing retirement and will be replaced by new capabilities before the end of the decade. New innovations from the private sector have reduced launch costs and opened up brand new opportunities for space exploration.

    Given that future U.S. BPS research will depend on the development of commercial space platforms, NASA should:

    • actively engage with commercial spaceflight firms to ensure that national science needs are met, and
    • establish an office or mechanism for commercial sponsorship and collaboration with government research agencies and academia

  • The BPS program and the community it supports are increasingly diverse and inclusive. However, much work remains to be done to address the persistent and troubling concerns of underrepresented groups in BPS research and to broaden participation at all levels of the research enterprise. NASA should ensure that diversity, equity, inclusion, and accessibility are integral to the nation’s space exploration science priorities.

    Two recent National Academies’ reports identify best practices for improving the health and vitality of NASA’s research communities. Many of their recommendations could be applied to BPS:

  • NASA’s commitment to open science—in the form of curated, maintained databases and physical repositories—encourages the research community to use existing data to improve experiment design, and offers the potential to build the space science research community beyond those investigators who are directly funded to generate such data.

    NASA should continue and expand the investment in open and shared computational infrastructure (CI) to support storage, analysis and dissemination of its biological and physical data, while ensuring linkage to the original and archived samples.

  • Many federal agencies, companies, and non-profit organizations have goals that are synergistic with the mission of the BPS community. The decadal survey recommends that NASA work with other U.S. government agencies to establish an office or mechanism to facilitate public-private partnerships.

    Beyond the U.S. government and industry, it is important that NASA continue to facilitate appropriate international partnerships on behalf of the BPS community that requires access to space. NASA should work with appropriate government agencies to establish clear guidelines for international collaborations within the biological and physical sciences, with the goals of advancing U.S. leadership in BPS research, fostering responsible partnerships with other space programs, and enabling U.S. access to other nations’ ground-based and space research assets.

    Finally, it is critical that BPS, and NASA as a whole, work to build public trust and ensure that space exploration moves forward in a transparent, responsible manner where the benefits are shared. This includes expanding efforts to communicate to the public about the value of BPS research.
