[NASA] SMD RFI: PRIVATE SECTOR ACTIVITIES IN ASTROBIOLOGY, PLANETARY
PROTECTION, AND SPACE BIOLOGY RELEASED

NASA's Science Mission Directorate (SMD) has released a new Request for
Information (RFI) entitled, Private Sector Activities in Astrobiology,
Planetary Protection, and Space Biology, seeking expressions of
interest from U.S. private sector, academic, nonprofit, and government
organizations interested in potential partnerships in astrobiology,
planetary protection, and space biology.

This RFI is intended to help NASA identify potential collaborators who
can contribute to advancing research, technology development, and
applications that support our broader efforts to understand the
origins, evolution, and distribution of life in the universe. Please
note that the RFI is not a solicitation. NASA does not intend to award
contracts, grants, cooperative agreements or Space Act Agreements. This
RFI is voluntary and strictly for planning purposes. For the full RFI,
please visit:

https://go.nasa.gov/PSPRFI

The RFI will be open for at least 60 days following the date of
release. All responses must be submitted through the NASA Solicitation
and Proposal Integrated Review and Evaluation System (NSPIRES) by
August 10, 2026, to be considered.

Other inquiries must be submitted using subject line "PSP RFI" by email
to:

[NASA] ROSES-25 AMENDMENT 58: F.17 RESEARCH INITIATION AWARDS FINAL
TEST AND DUE DATE

Research Initiation Awards (RIA) program aims to broaden the base of
institutions involved in the SMD research and technology development
ecosystem.

Eligibility requirements on both the PI and institution include:

- The proposing institution may not be an R1 institution according to
  the Carnegie Classification guide.
- The PI may not have received federal funding as PI of a project that
  is related to the proposed research activities within the last five
  years (with exceptions described in Section 2.2).

This opportunity is designed to support the executive order (EO)
Improving Oversight of Federal Grantmaking. In particular: Section 4
(D) iv that "Discretionary grants should be given to a broad range of
recipients rather than to a select group of repeat players" by
excluding R1 institutions (see Section 2.1). See also Section 4 (D).

Neither an NOI nor Step-1 proposal is requested. Proposals are due
August 18, 2026. An informational webinar about this opportunity will
occur at 1 p.m. EDT on June 16. Register for the webinar at:

https://tinyurl.com/bzd4fvz6

For the full announcement, go to:

https://solicitation.nasaprs.com/ROSES2025

Questions concerning F.17 RIA may be directed to Maggie Yancey at
hq-smd-ria@mail.nasa.gov.

COORDINATED ANALYSIS OF ASTROMATERIALS WORKSHOP AT THE UNIVERSITY OF
ARIZONA

We cordially invite non-UA student researchers to participate in an
in-person workshop on the coordinated analysis of astromaterials. The
workshop is scheduled for July 14-16, 2026, in Tucson, Arizona, at the
University of Arizona's Kuiper-Arizona Laboratory for Astromaterials
Analysis (K-ALFAA). Participants will receive both hands-on and
instructional training in analyzing planetary materials using various
types of instrumentation and in coordinating data sets. This training
opportunity is limited to 5 to 10 participants to ensure personalized
instruction. The workshop will focus on the various skills required to
optimize and coordinate micro- to nanoscale analysis of planetary
materials.

[DPS-58] LOW-COST MEETING OBSERVER OPTION

Are you interested in planetary science, and ready to attend
professional talks on topics of interest, but costs of a professional
conference are not affordable? DPS is pleased to announce a virtual
attendance option that can fit a tightly constrained budget, as a
virtual meeting observer. This option is meant for a wide variety of
planetary science amateurs and professionals:

- Amateurs who want a deeper dive than what is in the popular press
- Leaders of high-school science clubs who will share with a group
- Students and faculty at community colleges and tribal colleges
- Retired professionals who lack emeritus status in a professional
  society
- Active professionals who don't have funding to attend *all* the
  conferences they would like

The virtual attendance option, available for $50, allows full watching
and listening to oral presentations and access to recorded sessions.

[DPS-58] TRAVEL GRANT APPLICATIONS

The Division for Planetary Sciences (DPS) offers travel grants to
support attendance at DPS-58 to be held 25-30 October 2026 in Spokane,
Washington, U.S.A. At least 30 grants may be awarded at $500-$1500
each.

Hartmann Student Travel Grants support student presentations at the
annual DPS meeting. (Postdoctoral scholars may also be eligible, but
students are prioritized.) Award of a travel grant assumes submission
of a DPS abstract, to be described in the application.

Underrepresented Minority (URM) Communities in Planetary Science
Travel Grants support attendance by students and professionals who are
members of groups that have had inadequate access to the planetary
science community.

Applicants for DPS travel grants do not need to be U.S. citizens or
permanent residents. Eligible candidates are welcome to apply for both
grants, but if selected would receive only one. Apply here:

[DPS-58] DEPENDENT CARE APPLICATIONS

The Division for Planetary Sciences (DPS) offers Susan Niebur
Dependent Care grants to support attendance at DPS-58 to be held 25-30
October 2026 in Spokane, Washington, U.S.A. These grants provide
financial assistance to qualifying members to facilitate their meeting
attendance by offsetting costs for child care, elder care, spousal

[DPS-58] CONFERENCE LODGING

Please consider arranging your hotel for DPS-58 at official conference
lodging. There is a block of rooms at government rates, and lodging is
connected to the conference venue-the Spokane Convention Center-via a
covered a walkway. The hotel features an onsite restaurant and other
options are located nearby. Utilizing this lodging will cut both cost
to attend the conference and carbon footprint to attend the conference
by eliminating the need for car rental.

[DPS-58] STUDENT-LED REU PRESENTATIONS

The Science Organizing Committee for DPS-58 is aware that the regular
abstract deadline comes early for students participating in a summer
internship program such as Research Experiences for Undergraduates
(REU). When submitting a student-led abstract to DPS-58 that describes
work completed as part of an REU or other internship, authors are asked
to note in the "Special requests" field that the abstract is
student-led work from an REU or other internship, and whether oral or
poster presentation is desired. For such abstracts, oral presentation
will be considered even for submissions made as "late abstracts" by
July 2.
