No More Support For NASA SMD Planetary Science Division Analysis and Assessment Groups

Why It Matters

The move reshapes how planetary scientists coordinate mission planning and could alter the flow of expertise into NASA’s exploration portfolio, affecting funding and priority decisions across the sector.

Key Takeaways

• NASA ends formal funding for planetary AGs.
• Grant through LPI terminates by April 2026.
• Community may self‑organize AGs without NASA support.
• Ad‑hoc analyses could receive competitive solicitation funds.
• Reduced budget forces shift to alternative communication channels.

Pulse Analysis

For decades the Planetary Science Analysis and Assessment Groups have acted as the informal backbone of NASA’s planetary strategy, gathering scientists across disciplines to synthesize research, prioritize missions, and convey community consensus to decision‑makers. Operating under NASA‑approved terms of reference and funded through a grant administered by the Lunar and Planetary Institute, the eight AGs have facilitated two‑way communication, rapid special‑action teams, and early‑career mentorship. Their collective output has shaped everything from Mars rover payload selections to outer‑planet mission concepts, making them a unique conduit between academia and the agency.

In early 2026 Director Louise Prockter announced that, due to a cascade of policy shifts—including new executive orders, the dissolution of formal advisory committees such as the Planetary Science Advisory Committee, and tightened grant‑administration rules—NASA can no longer sustain the existing support model. A constrained Planetary Science Division budget further limited discretionary spending, prompting a review of all community‑funded mechanisms. The decision culminates in the termination of the LPI grant by April 2026, effectively ending NASA’s direct financial commitment to the AGs while preserving limited ad‑hoc funding avenues.

The cessation of formal backing forces the planetary community to rethink how it coordinates large‑scale assessments. Potential pathways include self‑organized consortia that seek competitive research grants, leveraging existing virtual platforms for workshops, or partnering with other federal or private entities for targeted studies. While the loss of guaranteed resources may slow consensus‑building, it also encourages innovative, leaner structures that could respond more quickly to emerging scientific priorities. Stakeholders are watching closely, as the new model will shape the agenda for future exploration missions and the distribution of research funding.
