INTERNATIONAL COMMISSION ON SPACE INFRASTRUCTURE RESILIENCE -
APPLICATIONS OPEN

The winners of the 2026 Schweickart Prize in Planetary Defense have
opened a global call for applications from experts interested in
shaping a safer and more resilient future in space.

As critical human systems and activities expand into orbit and across
the Earth-Moon system at an increasing rate, emerging infrastructure
will face natural planetary hazards that remain insufficiently
understood. Damage or disruption to orbital assets will produce
cascading consequences for the Earth-based systems and services that
increasingly depend upon them.

Anticipated periods of heightened meteoroid activity between 2028 and
2034, coinciding with rapid growth in orbital infrastructure,
underscores the urgency of the Commission's work.

The International Commission on Space Infrastructure Resilience will
convene specialists across science, engineering, space operations,
policy, law, economics, insurance, security, and related disciplines.
Together, they will develop authoritative multidisciplinary reports
examining natural space hazards, infrastructure risk, and practical
measures the international community can take now to strengthen
resilience, inform responsible development, and protect humanity's
expanding presence beyond Earth and systems on Earth.

Applications are invited from individuals able to contribute relevant
expertise, evidence, analysis, organization, management, and/or
institutional perspectives.

NEW HORIZONS OPEN SCIENCE TEAM MEETING #60 ON THE KUIPER BELT AND OUTER
HELIOSPHERE: ABSTRACTS DUE 31 AUGUST

Please join us at the next New Horizons (NH) Science Team Meeting #60
at Lowell Observatory, Flagstaff, AZ, 28-30 September 2026!

Currently at 65 au, NH is the only mission in the outer heliosphere and
Kuiper Belt, and is beyond most of the obscuring foreground of the
zodiacal cloud. It is measuring interstellar pick-up ions for the first
time together with solar wind plasma, energetic particles, and Galactic
Cosmic Rays. The encounter with the Termination Shock is estimated
between 2027 to the mid 2030's. NH's UV spectrometer and optical
telescope have uncovered unprecedented spectra of the cosmic background
and other features that may reveal new astrophysical processes in the
galaxy and beyond. NH's dust counter continues to detect a high dust
flux that is contrary to the theoretical expectations of a Kuiper
cliff, potentially pointing to a significantly extended Kuiper Belt.
Lastly, together with a ground-based search program, further, new
distant KBOs are being detected that NH can observe remotely to provide
critical constraints on planetesimal formation.

RISKS TO THE MARS EXPLORATION PROGRAM FROM SKYFALL (MEPAG UPDATE)

NASA announced that the SkyFall payload on the SR-1 mission will be
managed and funded out of the Mars Exploration Program (MEP), under
the MEP future missions budget line. SkyFall is an uncompeted payload
not identified as a priority in the Decadal Survey or Mars Future Plan.
Due to assignment of SkyFall to the MEP budget, plans for future
low-cost and commercial missions have been indefinitely delayed.
Extreme schedule and budget pressure to launch SkyFall in 2028 puts all
MEP activities at risk, including active missions.

In the strongest terms, MEPAG encourages NASA to continue supporting
the MEP program of record and the Mars Future Plan in parallel with
SkyFall to ensure progress on Decadal Survey science, preserve science
and engineering workforce capabilities, and build on the past success
of the MEP.

To increase awareness of this issue, I have shared the memo linked
below with key members of Congress (my own product, not a product of
MEPAG). Please use and share this document as needed to help spread the
word.

[AGU 2026] SESSION DI012: THE ROLE OF CORES - MULTIDISCIPLINARY
PERSPECTIVES ON THERMAL, CHEMICAL, AND MAGNETIC INFLUENCES IN EARTH AND
TERRESTRIAL PLANETS

We are convening the AGU 2026 session "The Role of Cores:
Multidisciplinary Perspectives on Thermal, Chemical, and Magnetic
Influences in Earth and Terrestrial Planets". We hope to bring together
researchers from across seismology, mineral physics, geochemistry, core
dynamics, (paleo)magnetism, geodesy and related fields to discuss how
metallic cores influence the properties and evolution of Earth and
other terrestrial bodies. We anticipate a lively and interdisciplinary
discussion and believe that your perspective would be a valuable
addition. Further details of the session can be found here:

https://agu.confex.com/agu/agu26/prelim.cgi/Session/281042

Thank you for your time and consideration. We hope to see you there!

[AGU 2026] SESSION SY029: OPEN SOURCE TOOLS FOR THE EARTH & SPACE
SCIENCES - BREAKING DISCIPLINE SILOS TO ACCELERATE DISCOVERY

Abstracts due: Wednesday, 5 August 2026, 23:59 PM EDT (03:59 UTC)

Link to session:

https://agu.confex.com/agu/agu26/prelim.cgi/Session/282486

This session invites contributors and users of open-source scientific
software from across the full breadth of AGU, from Earth's deep
interior to its surface, oceans, ecosystems, and beyond into space, to
share tools, workflows, and lessons learned. We welcome presentations
on software that enables reproducible science, supports FAIR data
principles, or integrates AI/ML approaches to accelerate discovery. A
central goal is cross-disciplinary exchange: exposing the community to
tools they may not encounter within their own discipline and fostering
new collaborations. Submissions may address software design, community
governance, interoperability with existing infrastructure,
cross-disciplinary reuse, AI and LLMs, or the challenges of sustaining
open-source projects. We aim to build a more connected and open science
software ecosystem.

Invited speakers: Tasha Snow, University of Maryland - College Park
(UMD), Nicolas Featherstone, Southwest Research Institute (SwRI),

[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] FIELD TRIP AT DPS-58 MEETING

The DPS-58 Local Organizing Committee is hosting a field trip to the
Channeled Scablands Sunday, 25 October, 8:00 am - 5:00 pm for
$165/person. Spokane, WA sits on the Columbia River flood basalt that
is an analog for basaltic flows on the Moon, Mars, Mercury, and Venus.
The Channeled Scablands were formed on the lavas by megafloods from
Pleistocene glacial Lake Missoula, and are an analog to Martian outflow
channels. The cost covers lunch and bus transportation from the
conference center and back in time for the opening ceremony. Most stops
are overlooks, but some have very short walks to outcrops. You must
register for the meeting and add the trip to your registration. Login
to the registration page with the same username and password that you
used to register, scroll down, add the trip to your itinerary, and
proceed to checkout.

[NASA] ROSES-25 AMENDMENT 68: NEW OPPORTUNITY - D.8 HABITABLE
WORLDS OBSERVATORY PRECURSOR SCIENCE INVESTIGATIONS

The Habitable Worlds Observatory (HWO) is a large-aperture
ultraviolet/visible/near-infrared observatory concept recommended by
the National Academies of Science, Engineering, and Medicine decadal
survey, "Pathways to Discovery in Astronomy and Astrophysics for the
2020s" (Astro2020). The HWO mission concept would be the first space
mission designed specifically to search for life outside our Solar
System and would be capable of performing transformative science across
astrophysics, areas of planetary science, and more. Habitable Worlds
Observatory Precursor Science Investigations (HWO-PSI) program element
D.8 of ROSES aims to advance the scientific foundation that would
reduce risk for a potential future HWO mission.

ROSES-2025 Amendment 68 releases D.8 Habitable Worlds Observatory
Precursor Science Investigations (HWO-PSI) as a new opportunity in
ROSES-25. Mandatory NOIs are due by September 10, 2026, and proposals
are due by October 26, 2026. Proposals submitted to this program will
be evaluated using dual anonymous peer review.

Questions concerning D.8 HWO-PSI may be directed to Megan Ansdell at
Megan.C.Ansdell@nasa.gov.
