ROSES-25 Amendment 2: Exoplanets Research Program Step-1

17 July 2025

Due Date Deferred to November 25, 2025

The Exoplanets Research Program (XRP), element F.3 of ROSES-25, solicits basic research proposals to conduct scientific investigations that significantly improve our understanding of exoplanets and exoplanet formation. This program element is cross-divisional and jointly managed by three of the Divisions within NASA’s Science Mission Directorate: Astrophysics, Planetary Science, and Heliophysics. Proposed investigations that combine multiple scientific disciplines or cross traditional Divisional science boundaries, for example, by including topics or analysis techniques from Heliophysics, are highly encouraged.

ROSES-2025 Amendment 2 defers the Step-1 due date for F.3 XRP to November 25, 2025.

On or about July 17 2025, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2025" (NNH25ZDA001N) will be posted on the NASA research opportunity homepage and will appear on SARA's ROSES blog.

Questions concerning F.3 XRP may be directed to John Wisniewski at hq-xrp@mail.nasa.gov.

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
