Workshop

The Community Science (Ad ASTRA) Workshop is organized by the NASA Astrophysics Division to engage the community in defining future large, strategic astrophysics missions. Structured over three thematic days—Science, Capabilities, and Missions—the workshop provides a comprehensive framework to connect scientific priorities with technological readiness and mission implementation. Across all three days, plenaries, panels, breakout sessions, and poster contributions are designed to maximize community input. The outcomes of the workshop will help NASA prioritize mission concepts and shape a balanced, forward-looking astrophysics portfolio.

This workshop is organized by the NASA Astrophysics Program Offices in partnership with the Infrared Processing and Analysis Center (IPAC).

Important Dates: 

  • Registration opens: March 31, 2026
  • Abstract deadline: June 24, 2026
  • Contributed talks/posters selection: July 1, 2026

This cropped horizontal image has layers of semi-opaque rusty red colored gas and dust that starts at the bottom right and goes toward the top left. There are three prominent pillars rising toward the top left. The left pillar is the largest and widest. The peaks of the second and third pillars are set off in darker shades of brown and have red outlines.
