TL;DR

This roadmap outlines a 30-year strategic vision for NASA Astrophysics, dividing future exploration into three eras—Near-Term, Formative, and Visionary—each building on technological advances and scientific discoveries to address fundamental questions about the universe, life beyond Earth, and cosmic origins. It proposes a science-driven, mission-based approach to enable transformative discoveries across astrophysics over the next three decades.

ABSTRACT

The past three decades have seen prodigious advances in astronomy and astrophysics. Beginning with the exploration of our solar system and continuing through the pioneering Explorers and Great Observatories of today, NASA missions have made essential contributions to these advances. This roadmap presents a science-driven 30-year vision for the future of NASA Astrophysics that builds on these achievements to address some of our most ancient and fundamental questions: Are we alone? How did we get here? How does the universe work? The search for the answers constitutes the Enduring Quests of this roadmap. Building on the priorities identified in New Worlds, New Horizons, we envision future science investigations laid out in three Eras, with each representing roughly ten years of mission development in a given field. The immediate Near-Term Era covers ongoing NASA-led activities and planned missions. This will be followed by the missions of the Formative Era, which will build on the preceding technological developments and scientific discoveries, with remarkable capabilities that will enable breakthroughs across the landscape of astrophysics. These will then lay the foundations for the Daring Visions of the Visionary Era: missions and explorations that will take us deep into unchartered scientific and technological terrain. The roadmap outlined herein will require the vision and wherewithal to undertake highly ambitious programs over the next 30 years. The discoveries that emerge will inspire generations of citizen scientists young and old, and inspire all of humanity for decades to come.

Motivation & Objective

• To define a long-term, science-driven roadmap for NASA Astrophysics over the next 30 years to address fundamental cosmic questions.
• To identify and prioritize key scientific missions across three distinct eras—Near-Term, Formative, and Visionary—based on technological readiness and scientific impact.
• To build on prior frameworks like New Worlds, New Horizons to ensure continuity and strategic progression in astrophysical exploration.
• To inspire future generations through ambitious, transformative missions that push the boundaries of scientific and technological innovation.
• To guide investment and mission development by aligning priorities with enduring scientific quests in cosmology, exoplanets, and high-energy astrophysics.

Proposed method

• Divides the 30-year vision into three 10-year eras: Near-Term (ongoing and planned missions), Formative (technology-driven breakthroughs), and Visionary (ambitious, exploratory missions).
• Uses science-driven prioritization based on key questions: 'Are we alone?', 'How did we get here?', and 'How does the universe work?'
• Leverages technological advancements from previous missions, such as the Great Observatories and Explorer-class missions, to inform future mission design.
• Emphasizes mission development cycles with phased investment and technology maturation to ensure feasibility and scientific return.
• Integrates input from leading astrophysicists across diverse subfields to ensure broad scientific coverage and interdisciplinary alignment.
• Proposes a structured, scalable approach to mission planning that balances near-term progress with long-term visionary goals.

Experimental results

Research questions
