[EDITORIAL] THE NEED FOR LUNAR GEOLOGISTS
NASA has launch fever to hire commercial space companies to land on the
Moon and develop a booming lunar economy. But there's a huge, glaring
problem: the mission planners, technologists, and engineers don't seem
to realize how badly they need lunar geologists!
Let's talk about the rocks you'll find up there. The lunar highlands
are made of a mineral called anorthite, while the lowlands are mostly
the volcanic rock basalt-basically the same lava rocks as Hawaii. Want
to mine titanium? You need to know the difference between high-titanium
and low-titanium basalt. Want heavy metals? Look for pyroclastic
deposits around volcanic vents. The Procellarum KREEP terrain is rich
in the rare earth elements we need for consumer electronics, plus a
radioactive element called thorium that we can use for lunar nuclear
reactors.
So, commercial mission planners: hire a lunar geologist. We promise
we're fun, even if we just want to stare at dusty rocks all day.
Because that's where the money is.

LAST CALL TO COMMENT ON PROPOSED RULES FOR FEDERAL GRANT-MAKING
The comment period for the White House Office of Management & Budget's
proposed "Uniform Guidance" for federal grants closes on Monday, July
13, at 11:59 PM ET. The OMB's proposed rules would add new bureaucratic
barriers, partisan political review, and restrictions on publication
and public outreach for federally-funded research.
More than 100,000 comments, nearly all in opposition, have already been
submitted to the proposed rule from scientists across every discipline
and members of the general public. The near unanimous opposition saw a
major win when Senator Susan Collins, the top Republican on the Senate
Appropriations Committee, warned in a July 6 letter that the new rules
"would impose new, burdensome requirements on award recipients that
would harm small and rural communities, undermine scientific and
biomedical research, and conflict with Congress' control over the
federal funding process."
Add your voice to inform federal regulators, legislators, and the
courts about the harmful impacts these proposed rules will have on
planetary and space science. Read more about the issue and submit your
comment using The Planetary Society's advocacy action center:

[NASA] SMD: DRAFT SOLAR SYSTEM EXPLORATION RESEARCH VIRTUAL INSTITUTE
(SSERVI) COOPERATIVE AGREEMENT NOTICE (NNH26ZDA013J) RELEASED FOR
COMMENT
The National Aeronautics and Space Administration (NASA) Science
Mission Directorate (SMD) and Human Spaceflight Mission Directorate
(HSMD) have released the draft of the fifth Solar System Exploration
Research Virtual Institute (SSERVI) Cooperative Agreement Notice
(CAN-5) as NNH26ZDA013J for public comment.
SSERVI CAN-5 invites the submission of multi-institutional team-based
proposals for research as participating members of the Solar System
Exploration Research Virtual Institute (SSERVI). Proposals must
clearly articulate an innovative research program addressing basic
and/or applied research fundamental to understanding the nature of the
Moon and its near space environment to enable future human exploration
of the Moon with Artemis. "Mars forward" proposals that use
lunar-focused research to develop approaches to Mars exploration also
are welcome.
A SSERVI Draft CAN 5 Pre-Proposal Conference is scheduled for July 17
at 1:00 PM ET. During this Pre-Proposal Conference, representatives
from the co-sponsoring organizations will provide an overview of
SSERVI, the scientific and exploration focuses sought in the CAN, as
well as answer community questions. This event will NOT be recorded.

PARTNERS IN DISCOVERY: ADVANCING NASA SCIENCE WITH NEW MODELS OF
COMMERCIAL AND UNIVERSITY COLLABORATION
The Commercial Space Federation, The Planetary Society, and Arizona
State University will host the "Partners in Discovery" workshop,
reception on August 31 and meeting days on September 1 & 2, 2026 at ASU
DC. Registration is filling up and attendance is limited.
With the exception of a few programs that comprise a very small portion
of NASA's budget, NASA's basic approach to supporting science hasn't
changed much in the past 25 years. PI-led missions and flagships have
comprised the vast majority of the mission portfolio. With NASA's
recent announcements at the Ignite event and growing commercial
involvement in lunar exploration, this approach is ripe for evolution.
While the opportunity to drive change is great, there are fundamental
questions to be addressed to enable the transition into a more
aggressive commercial-university partnership mode to advance NASA
Science. We seek to start answering those questions at the workshop
through panels of invited speakers and time for breakout discussions
amongst attendees.

ICE GIANT SYSTEMS SEMINAR SERIES: RICHARD ANDERSON AND JACOB ENGLANDER
(APL)
Date/Time: July 14, 11am ET
Speaker: Richard Anderson and Jacob Englander (APL)
Topic: A High-Heritage, Low Risk Approach to Uranus Orbiter and Probe
Abstract: Following the decadal survey, it became clear that NASA's
funding profile did not support the recommended 2031 or 2032 launch for
Uranus Orbiter and Probe (UOP), nor does it support a spacecraft with
three next generation radioisotope thermal generators (RTGs). Starting
in 2023, a team of scientists and engineers at the Johns Hopkins
Applied Physics Laboratory and NASA's Goddard Space Flight Center
worked together to further develop UOP such that it could launch in any
year and operate under a more restrictive energy budget. This study
included a detailed design of the orbiter and probe, as well as a
solar-electric propulsion (SEP) transfer stage to take the place of the
Jupiter gravity assist that is no longer available in the years that
UOP may launch.

[AGU 2026] SESSION IN019: EMULATION FRAMEWORKS FOR PHYSICS-BASED
MODELS: A CROSS-DOMAIN ASSESSMENT OF METHODOLOGIES
We invite you to submit an abstract to a new AGU 2026 session that
fosters a cross-domain conversation about emulator frameworks. Abstract
submission is open and the deadline to submit is August 5, 2026:
https://agu.confex.com/agu/agu26/prelim.cgi/Session/282994
Emulating physics-based models is vital for maximizing the science
return of next-generation instruments and enabling near-real-time
digital twins, rapid discovery, and rigorous uncertainty
quantification. This session seeks to showcase an assemblage of
specific emulator or surrogate frameworks - whether using reduced-order
physics, statistical methods, or machine learning - that are well
suited for different modeling challenges such as overcoming
computational bottlenecks or improving model understanding and
uncertainties. We invite contributions that discuss motivations for
emulator and surrogate technology and present architectures tested for
specific scientific applications. We encourage sharing lessons learned,
particularly regarding interactions across varying spatial, temporal,
and spectral scales, adherence to physical laws, and domain-specific
validation strategies. By bringing together these techniques, this
session aims to map the landscape of advanced computational methods,
evaluate transferability between domains, and advance our collective
technical literacy of this emergent technology space.

Abstracts due: Wednesday, 5 August 2026, 23:59 PM EDT (03:59 UTC)
Session Link:
https://agu.confex.com/agu/agu26/prelim.cgi/Session/282972
We invite submissions to the following session focused on planetary
volcanism. Silicate volcanism has fundamentally shaped the surfaces
and interiors of terrestrial bodies, including Mars, the Moon, Venus,
and Io. From extensive ancient volcanic eruptions to geologically
recent activity, volcanic processes play a key role in interior thermal
evolution, crustal production, atmospheric replenishment, and
regulation of habitable environments. Recent observations of diverse
eruption styles on Mars, potentially ongoing activity on Venus, and
anomalously young volcanism on the Moon, have challenged established
timelines of volcanic and thermal evolution. Many questions still
remain regarding the mechanisms of volcanic processes across different
planetary environments, eruption styles, and atmospheric interactions,
making a review and discussion of these processes across multiple
planetary bodies timely. This session invites contributions that
advance our understanding of planetary volcanism, including through
numerical modeling, remote sensing analyses, in situ observations, and
terrestrial analog studies. Contributions focusing on individual bodies
and/or cross-body comparisons are welcome.

[AGU 2026] SESSION: P023: RADAR INVESTIGATIONS OF PLANETARY SURFACES
AND SUBSURFACES
Call for abstracts: We welcome and encourage you to submit abstracts to
the AGU26 Fall Meeting Session: P023 - Radar Investigations of
Planetary Surfaces and Subsurfaces.
Session Link:
https://agu.confex.com/agu/agu26/prelim.cgi/Session/279957
Description: Proposed and existing radar instruments are enabling an
unprecedented range of radio geophysical observations of the surfaces
and subsurfaces of Solar System bodies. This has spurred the
development and application of new instrumentation, processing,
modeling, analysis, and interpretation approaches to planetary radar
science and engineering. We invite abstracts on any topic involving the
use of radar data to understand planetary bodies. These may describe
(but are not limited to) new results from existing radar observations,
the development and application of new observation or data processing
techniques, numerical modeling of existing or future observations,
and/or the analysis of airborne or orbital radar data from terrestrial
analog studies for Solar System observation.
Abstract Submission Deadline: 5 August 2026 (23:59 EDT / 03:59 UTC)
We look forward to receiving your abstracts and creating an engaging
session for the community!

[AGU 2026] SESSION SA011: ENABLING ADVANCES IN SPACE SCIENCE THROUGH
CITIZEN SCIENCE INVESTIGATIONS
Please join us at the 2026 AGU Annual Meeting by submitting an abstract
to our session, SA011: Enabling Advances in Space Science through
Citizen Science Investigations:
https://agu.confex.com/agu/agu26/prelim.cgi/Session/281425
With the push for expanding citizen science-based projects and recent
science results, such as those related to the Heliophysics Big Year
(HBY), citizen science is becoming an enabling mechanism for scientific
investigations. These investigations also incorporate an increasingly
diverse array of datasets and methodology, including crowd-sourced
spatially distributed datasets, different kinds of visual
classifications of auroral, solar, and lunar terrain images, feature
identification in particle spectra, and auditory classifications of
wave power spectral densities. This session focuses on the scientific
motivation and outcomes of citizen science projects in the space
sciences, highlighting studies that have been actively developing and
using citizen science-derived datasets across heliophysics and
planetary science. Along with results from citizen science
investigations, presentations describing challenges and lessons learned
(i.e., working with different platforms, interfacing with volunteers,
tailoring tasks for accessibility while still retaining scientific
usability, etc.) are welcome.
Hope to see you there!

[AGU 2026] SESSION U010: EARTH AND SPACE SCIENCE IN THE ERA OF NASA'S
ARTEMIS - A LUNAR SURFACE BASED OBSERVATORY CONCEPT
Please consider submitting an abstract to U010:
https://agu.confex.com/agu/agu26/prelim.cgi/Session/280185
The concept of an Earth-viewing lunar observatory was first proposed at
the 2007 NASA Lunar Workshop and noted certain advantages including a
stable platform, serviceable instrumentation, and unique views of the
Earth. With the recent success of NASA's Artemis II Mission and the
planned increase of future missions leading to a lunar base by late
2028, an opportunity will exist for an outward looking 'lunar eye'
science observatory on the surface. With the potential of permanent
power stations and the involvement of the commercial sector, this
observatory concept could host not only Earth, but Planetary,
Heliophysics, and Astrophysics instruments that enable new
multi-decadal observations and answer novel science questions of the
Earth, the Sun, and the cosmos. This session is designed to bring
together those interested in the potential science, instruments, and
observatory infrastructure concepts for conducting future Earth and
Space science not of the moon, but from the moon.
Thank you!
