After 15 years of leadership, Bill Nye will step down as chief executive officer of The Planetary Society and transition into two new roles: vice chair of the organization’s board of directors and chief ambassador, the nonprofit announced today. Jennifer Vaughn, the Society’s longtime chief operating officer, will assume the role of CEO on February 17, 2026.

The announcement coincides with the 15th anniversary of Nye’s appointment as CEO in 2010. Nye first joined The Planetary Society as a charter member in 1980 and later served on its board of directors before taking on the organization’s top leadership role. During his tenure, he guided the Society through a period of significant growth while advancing its mission to empower people worldwide to advance space science and exploration.

“After 15 years as The Planetary Society’s chief executive officer, I’m stepping down, or aside,” Nye said in a statement published on the organization’s website. “I will transition out of my role as CEO — but I won’t be stepping away from The Planetary Society. Jenn Vaughn has been my closest partner in leading the organization. She helped craft our mission, and she is a natural leader with a clear vision for the future. We could not be in better hands.”

Under Nye’s leadership, The Planetary Society championed and launched LightSail 1 and LightSail 2, the first small spacecraft to successfully demonstrate solar sailing in Earth orbit. Funded by Society members, the missions received recognition from TIME and Popular Science. The organization also expanded its support for scientific research through the STEP (Science and Technology Empowered by the Public) grant program.

The Society played a key advocacy role in major space missions, including New Horizons, Europa Clipper, and Mars microphone experiments, as well as in the development of PlanetVac, which successfully flew on a lunar mission. Efforts to strengthen planetary defense included global support for asteroid tracking through the Shoemaker Near-Earth Object Grant Program.

Public policy and engagement initiatives also expanded during Nye’s tenure, including the establishment of the Planetary Science Caucus in Congress and the launch of the annual Day of Action, which mobilizes hundreds of citizen advocates each year. Public outreach grew through large-scale events such as Planetfest and eclipse festivals, as well as new educational initiatives, including the Planetary Academy for children.

Internally, the Society experienced substantial growth and evolution, highlighted by its first comprehensive fundraising effort, the $40 million Beyond the Horizon campaign. Annual philanthropic support increased by nearly 300%, from $2.8 million in 2010 to $8.2 million in 2025.

In his new role as chief ambassador, Nye will continue serving on the board as vice chair and represent The Planetary Society publicly through media appearances, advocacy, and events, including ongoing work in Washington, D.C.

Incoming CEO Jennifer Vaughn has been with The Planetary Society since 1996 and has served as chief operating officer since 2011. Her work has encompassed organizational strategy, membership growth, fundraising, education and outreach programs, science funding initiatives, and operations.

“This is a moment of both reflection and renewal,” Vaughn said. “Bill’s vision, energy, and belief in our mission have helped shape who we are today. I’m honored to carry that legacy forward and lead the Society into its next chapter.”

The leadership transition follows years of succession planning and reflects a commitment to continuity. The Planetary Society remains an independent, member-funded nonprofit with a global reach, focused on advocating for space exploration, advancing science and technology, and engaging the public in the exploration of the cosmos.
