MAST is seeking suggestions from the entire astronomical community regarding possible new datasets for this initiative through a public questionnaire. Any non-Roman datasets, which are publicly available by September 2027, can be considered. (Datasets not already held at a NASA archive, or not currently cloud-hosted, will be prioritized.) Submissions should include a description (of approximately 1-3 paragraphs) addressing how the dataset will impact Roman science, which surveys/science cases will be facilitated by its inclusion, and why its current location is insufficient for co-analysis with Roman data and thus hosting it at MAST is critical. Final selections will be made by MAST and Roman leadership, considering (1) Impact to Roman science, (2) Cost given available resources, and (3) Ensuring balance of which surveys and science cases are facilitated. Multiple submissions are welcome; please only include a single dataset per submission. Submissions will be accepted through **31 March 2026**. Please direct questions regarding this questionnaire and initiative to the MAST Help Desk at archive@stsci.edu. ## News Straight to Your Inbox Subscribe to your community email news list We will never share your email address.

The goal is to give the mission concept teams opportunities to identify potential new science cases; to identify interested community members who might want to support or join the mission concept effort; and to increase the visibility of all relevant projects at this early stage in the process. The first of these will be on **7 May 2026** at **4p Eastern** (1p Pacific), where we will hear presentations from: * Nautilus * Ardua * HOEE: Hybrid Observatory for Earth-like Exoplanets * MIRECLE: MIR Exoplanet CLimate Explorer We anticipate having another 1-2 such webinars before the 14 June (hybrid) ExoPAG34 meeting, which will also focus mainly on mission concepts and ASTRA; stay tuned.

Reminder: NASA Astrophysics... * About * Community * Program Analysis Group (PhysPAG) * Science Groups * News & Events * Cosmic Pathfinders * Science Gaps * Early Career Workshops * Opportunities * Missions * Studies * News & Events * Resources # Reminder: NASA Astrophysics Division Update Webinar 10 March 2026 9 March 2026 The NASA Astrophysics Division Director, Shawn Domagal‑Goldman, will provide an update in a webinar on **10 March 2026** , **12 noon-1p Eastern** (9a-10a Pacific). NASA’s Astrophysics Division is dedicated to pushing the boundaries of discovery and ensuring that America remains at the forefront of space science. We study how the universe began and evolved, how it works, and where life might exist beyond the solar system. NASA’s Astrophysics Division established three focused programs that provide an intellectual framework for advancing science and strategic planning: Physics of the Cosmos (PhysCOS), Cosmic Origins (COR), and Exoplanet Exploration (ExEP). Each program primarily addresses one of the three most fundamental questions related to astrophysics: “How did we get here?” (COR), “How does the universe work?” (PhysCOS), and “Are we alone?” (ExEP). The community members of the three programs, referred as Program Analysis Groups, serve as an interdisciplinary forum for soliciting and coordinating community analysis and input in support of the Programs’ objectives. In this talk, Shawn Domagal‑Goldman will address the community from the three Program Analysis Groups and will present updates from NASA’s Astrophysics Division, recent scientific and technical achievements, and upcoming funding opportunities. He will also announce two workshops that will be held during 2026 to begin engagement between NASA and the community, the _Innovation for Astrophysics Missions Workshop_ (27-28 May) and the _Astrophysics Community Workshop_ (September, dates TBD). Opportunities for the Program Analysis Groups to get involved with these activities will be discussed. The session will include a Q&A period. Connection details and a link to the Q&A portal are available on this webpage. ## News Straight to Your Inbox Subscribe to your community email news list We will never share your email address.

This talk surveys the scientific motivation across four complementary regimes. At low radio frequencies, the radio-quiet lunar farside opens a window onto the cosmological Dark Ages and the magnetospheres of exoplanets. In the mid-band gravitational-wave regime, the Moon's low seismic activity bridges the sensitivity gap between terrestrial and space-based detectors. At ultraviolet wavelengths, its natural vacuum and long coherence times allow high-resolution stellar imaging beyond what is possible on Earth. And in the far-infrared, the cold, stable conditions of permanently shadowed regions offer a naturally cryogenic, absorption-free site for probing star and planet formation and the obscured Universe. For each regime, I will share updates from the mission concept leads on the efforts now developing within the Astrophysics from the Moon, Mars & Beyond (AMMB) Science Interest Group. Together, these cases point to a paradigm shift: astrophysics from the Moon is becoming not just desirable but necessary. ## Seminar Connection Join the Seminar ## News Straight to Your Inbox Subscribe to your community email news list We will never share your email address.
