[NASA] SMD: CURRENT ROSES REMAINS OPEN, NEXT ROSES LATE 2026

NASA's Science Mission Directorate (SMD) traditionally releases
Research Opportunities in Space and Earth Sciences (ROSES), its
umbrella Notice of Funding Opportunity for research grants, on an
annual basis. The current edition was released in July 2025. NASA plans
to release ROSES-27 no later than January 2027. 
 
ROSES-27 will support research addressing fundamental questions about
our planet and the universe, connecting scientific discovery with
exploration. It advances the President's National Space Policy and the
goals outlined through NASA's Ignition, Faster to Science, and Golden
Age of Science initiatives: accelerating discovery, enabling bold
research, and investing in the next generation of scientists. By
engaging the research community in advancing these initiatives, SMD is
creating opportunities to pursue bold ideas, answer fundamental
questions about our planet and the universe, and prepare the next
generation of scientists to carry that work forward.
 
Questions regarding those individual ROSES-25 program elements should
be directed to the points of contact for those programs. Questions
regarding ROSES generally may be directed to SARA@NASA.gov

PHD POSITION IN PLANETARY SCIENCES/ASTROBIOLOGY - UNIVERSITY OF
CALIFORNIA, RIVERSIDE

The Center for Astrobiology and Analog Worlds at the University of
California, Riverside invites applications for a PhD position studying
the Uranian system. The successful candidate will work with Stephen
Kane and Fabian Klenner to investigate the major icy moons of Uranus as
potential ocean worlds. The research will focus on volatile outgassing
and the evidence it may provide for subsurface oceans, as well as the
dynamical and tidal processes that drive interior heating and surface
activity. The student will work with data from a range of observing
facilities, including high-resolution spectroscopy from the W. M. Keck
Observatory and the MINERVA-Australis array, and will develop the
modeling framework needed to connect these observations to the moons'
interior states. This research directly supports the science case for
NASA's planned Uranus Orbiter and Probe (UOP) flagship mission,
positioning the student at the forefront of ice giant system science in
the lead-up to the mission era. The position offers training spanning
observational astronomy, geophysics, and planetary geochemistry. For
more information, please contact either Stephen Kane (skane@ucr.edu) or
Fabian Klenner (fabiank@ucr.edu).

POSTDOCTORAL RESEARCHER POSITIONS AT THE UNIVERSITY OF VIRGINIA

The University of Virginia (UVA) invites applications for multiple
Postdoctoral Research Associate positions as part of the new,
interdisciplinary Interconnected Cosmos Initiative (ICI). ICI brings
together astronomy, physics, chemistry, environmental sciences,
engineering, and partners such as the National Radio Astronomy
Observatory (NRAO) to tackle major questions in modern planetary
science, astrophysics, astrochemistry, and cosmology. Each Postdoctoral
Research Associate will have two mentors whose primary appointments
cross departments or institutions. Prospective applicants interested in
planetary surface processes are encouraged to contact Prof. Ajay Limaye
(ajay@virginia.edu) in the Department of Environmental Sciences to
discuss potential interdisciplinary collaborations.

All positions will be based at UVA in Charlottesville, Virginia, and
will begin with an initial one-year appointment, with the expectation
of annual renewal up to three years, contingent upon satisfactory
performance and the availability of funding.

JWEBBINAR #53: THE OPTICAL CONSTANTS DATABASE AND JWST

Please join us for a James Webb Space Telescope (JWST) webinar
(JWebbinar) dedicated to the Optical Constants database (OCdb) and its
use in PICASO and VIRGA models to analyze and interpret JWST
observations of brown dwarfs and exoplanets. This JWebbinar will be
presented by Ella Sciamma-O'Brien, Lora Jovanovic, Sarah Moran, and
James Mang.

The JWebbinar is scheduled for Wednesday November 4, 8-10 a.m. (PST)
and is organized by the Space Telescope Science Institute (STScI).

Register by October 29 at:

https://tinyurl.com/v497rx25

The Optical Constants database (https://ocdb.smce.nasa.gov), developed
at NASA Ames, centralizes published optical constants of materials
relevant to (exo)planetary and astrophysical environments, making them
more accessible to the community.

This JWebbinar will provide: 

1) a demo of the OCdb website: how to search the database content,
   utilize its online tools for simple analyses, and download data; 
2) how to use OCdb data in the PICASO (https://lnkd.in/grvYG4Gc) and
   VIRGA (https://lnkd.in/geWHaCnn) models to analyze and interpret
   JWST observations of brown dwarfs and exoplanets.

In this hand-on session, there will be time for participants to ask
questions, discuss OCdb and exoplanet/brown dwarf-related topics, and
provide input on next steps for OCdb.
