NASA skips 2026 research call, The Planetary Society reports
The reported gap affects a major funding route for US researchers, while NASA continues existing opportunities and plans its next call by January 2027.
The reported gap affects a major funding route for US researchers, while NASA continues existing opportunities and plans its next call by January 2027.

NASA is skipping the 2026 proposal round for Research Opportunities in Space and Earth Sciences (ROSES), The Planetary Society reported on October 23, 2026. The programme is a major route through which NASA funds scientists at universities and research institutes across the United States.
According to the Society, ROSES typically funds hundreds of millions of dollars’ worth of research projects. The reported omission concerns the annual proposal round, not a halt to all research funding: NASA continues to add opportunities to ROSES-25, the current edition.
In its October 20 announcement, NASA said it plans to release ROSES-27 no later than January 2027. That announcement sets out the next call’s timetable without explicitly confirming cancellation of ROSES-26.
NASA’s listed ROSES-25 proposal deadlines run from November 10, 2026, to March 16, 2027. Some programmes require an earlier notice of intent—a statement that a researcher plans to apply—or a first-stage submission. The mandatory notice deadlines for the astrophysics networks and cryosphere programmes have already passed.
| Programme | Earlier requirement | Proposal deadline |

| Planetary Science Enabling Facilities | None listed |

The NIH–NASA competition seeks better measurements in laboratory drug-safety models, with submissions scheduled to open on 15 December 2026.

NASA expects ROSES-27 to invite proposals through approximately 50 programme elements, or individual research opportunities. These would span astrophysics, biological and physical sciences, Earth science, heliophysics, lunar and planetary science, and research crossing those fields.
NASA says publishing the planned release window helps researchers and institutions prepare proposals, build teams and support students and early-career scientists. Its next stated step is to release ROSES-27 by January 2027.

The programme brings together national laboratories, universities and industry partners, with plans for a sensor-equipped test bed and self-adjusting pilot production lines.
