Policy is the prime mover of space exploration. It sets in motion government resources, defines regulatory requirements, and releases funds from national treasures. Good policy is therefore critical for success in space.
In this submission to the 2023 - 2032 planetary science decadal survey, The Planetary Society argued for the importance of the search for life, not just as an inspiring goal, but as a means to achieve a scientific revolution within the biology and medicine. Unlike past revolutions, searching for life presents a clear pathway for success: we know how to do it and we know where to look.
Increasing the Scope of Planetary Defense Activities: Programs, Strategies, and Relevance in a Post-COVID-19 World (PDF)
In this submission to the 2023 - 2032 planetary science decadal survey, The Planetary Society argued that, due to COVID-19, the public is very aware of the value of disaster preparation. Combined with the coming Apophis flyby, there is a new immediacy for investments into planetary defense, the ultimate "low probability, high impact" event. We recommended that the scientific community embrace planetary defense and endorse a permanent mission line.
Thinking Big: How Large Aperture Space Telescopes Can Aid the Search for Life in Our Lifetimes (PDF)
In this submission to the Astrophysics decadal survey, The Planetary Society discussed the capabilities needed to conduct the most scientifically compelling endeavor currently facing space science: the search for life elsewhere. It includes context for NASA's search for life beyond the Earth, including the organization's assessment of public support for this effort, and ways for the Astro2020 process to address this goal, including "going big" on large space telescopes to enable statistically-significant detections of biosignatures in the atmospheres of exoplanets.
NASA's Mars Exploration Program has systematically worked to understand the Red Planet through robotic missions of exploration. It enabled a revolution in humanity’s knowledge of Mars and methodically worked to achieve the top Mars science goal—sample return to Earth. The Planetary Society's analysis, however, found a fundamental contradiction in NASA’s extant Mars plans: there is not much of a program anymore within the Mars Exploration Program. This is a troubling path of decline—and decisions must be made now in order to stop it.
Presented to the Trump transition team prior to taking office in 2017, this report outlined ways in which space science and exploration could be pursued at the U.S. space agency.
The Planetary Society held a workshop on the future of human exploration of Mars in Washington, D.C. in 2015. Nearly 80 participants from various NASA centers, the scientific community, academia, and government attended. The workshop featured the orbit-first concept of Mars exploration as proposed by a team from NASA's Jet Propulsion Laboratory. Orbit-first would send astronauts near the Moon throughout the 2020s, to Mars orbit and Phobos in 2033, and finally to the surface of Mars by 2039 to begin an ongoing program of exploration.

The cost of the Perseverance rover disappears into the noise of U.S. spending and represents a more modest investment than you might think.
Advocating for space at every step in the process, The Planetary Society submitted two papers to the forthcoming planetary science decadal survey—one on the search for life and one on the importance of planetary defense.
NASA's commercial crew program stands to be the agency's lowest-cost human spacecraft effort in nearly 60 years.
