PETITION: CHANGE THE WAY ESA HIRES AND CONTRACTS

I recently posted an opinion piece entitled "ESA, the European 
Suboptimal Agency". In it I express my concern and thoughts about why 
I think the geo-return policy at ESA for hiring and contracting needs 
to change.

From received feedback I conclude that more people have similar 
concerns. Following a suggestion from this feedback I set up a 
petition. Find the full story with all links at:

Infrared observations from JWST have rapidly become a cornerstone in 
the current era of Solar System exploration. The Planetary Science 
Group within Leicester's School of Physics and Astronomy is inviting 
applications for a Postdoctoral Research Associate (PDRA) in planetary 
atmospheres. The PDRA will join a team led by Professor Leigh 
Fletcher, and will be supported by a European Research Council (ERC) 
Advanced Grant known as "JWSTVoyager."  This project aims to study the 
origins, atmospheres, and variability of the four giant planets using 
a combination of JWST, ground-based, and Juno observations. The PDRA 
will have access to existing (and forthcoming) observations from JWST, 
coupled with cutting-edge data processing tools. You will work to 
invert infrared and microwave spectra with a suite of radiative 
transfer and retrieval tools, using these to derive temperatures, 
winds, composition, and clouds, which will then be used to address 
the core themes of JWSTVoyager.

EUROPA CLIPPER LECTURE SERIES: ALL EYES ON EUROPA CLIPPER 

Speaker: Dr. Bonnie Buratti (JPL)

Date: Tuesday, October 13, 2026, 10am PT/ 1pm ET

Calling all professional and amateur astronomers and Europa 
enthusiasts! Come hear a talk about imaging NASA's Europa Clipper 
spacecraft during its Earth flyby on December 3, 2026 UT, given by 
Deputy Project Scientist, Dr. Bonnie Buratti.

The spacecraft is unlikely to be visible to the naked eye, yet 
professional and amateur astronomers can observe and image Europa 
Clipper during nighttime following the gravity assist. Closest 
approach takes place over Africa on December 3, 2026 UT, with 
visibility for at least a week. Time has already been assigned on the 
200-inch Hale Telescope. Public engagement will include schools, 
especially higher education institutions with access to medium-sized 
telescopes, astronomy clubs, and individuals, providing the public an 
avenue to engage in and support the mission.

The plan is to publish a paper in a scientific journal on the 
campaign, and its success in advancing outreach and public engagement, 
and in conducting a successful citizen science effort.

sign up for notice of future Europa Clipper Lecture Series talks:

[DPS-58] ALL EYES ON EUROPA CLIPPER SPLINTER WORKSHOP AT DPS

"All Eyes on Europa Clipper" is a public outreach and engagement 
activity for both professional and amateur astronomers and students to 
image the path of the Europa Clipper spacecraft with medium-sized 
telescopes during its gravity assist at the Earth on December 3, 2026. 
There will be a lunchtime splinter workshop on the Program at the 2026 
DPS meeting on Tuesday October 27. Sign up to participate in "All Eyes

[DPS-58] ANNOUNCEMENT OF PROPOSAL WRITING WORKSHOP AT DPS58

58th Division for Planetary Science Conference:

https://aas.org/meetings/dps58

Proposal Writing Workshop: Using NASA ROSES as an example

Sunday, October 25, 2026, 9:00 AM-4:00 PM Pacific.

Spokane Convention Center Room 205

Note: In person only; available to all registered participants of DPS

The success of scientists depends upon their ability to obtain 
funding. One of the largest challenges is to create strong proposals. 
Using Research Opportunities in Space and Earth Sciences (ROSES) from 
NASA Science Mission Directorate as a template, this presentation will 
focus on teaching the audience key points to communicating science 
through successful proposal writing. As a result of this session, 
participants will be able to understand the proposal writing, 
reviewing, and selection process for federally funded research. How to 
understand one's values and maintain those throughout this process 
will also be focused on. We greatly appreciate support for this (and 
other upcoming workshops) from the NASA Science Mission Directorate!

[DPS-58] DPS WORKSHOP: URANUS SOLSTICE CAMPAIGN

The Uranian northern summer solstice in 2030 marks an important 
transitional period for the planet itself and presents a unique 
viewing geometry of the planet, its satellites, and its rings. This 
DPS workshop is a kickoff meeting for the community to identify key 
observations uniquely attainable during the 5 year time frame leading 
up to and following solstice in 2030. Science areas include Uranus' 
atmosphere, ionosphere, rings, satellites, magnetosphere, and more. 
The workshop will discuss critical needs for modeling efforts and 
which facilities could be used to acquire the requisite observations. 
We expect to produce a white paper that captures the results of the 
kickoff and future community discussions in order to best guide 
planned observations during the Uranian Solstice period.

at 11:45am Pacific. This will be a hybrid meeting, taking place in 
person at the DPS Meeting in Spokane WA, and also accessible via Zoom. 
The meeting will take one hour.  

The PDS Ring-Moon Systems Node (RMS) hosts data and tools in which the 
focus is on planetary systems in the outer Solar System. Topics of 
interest include icy satellite surfaces and planetary atmospheres, in 
addition to rings and other dynamical systems. 

This meeting is an opportunity for friends of the PDS Ring-Moon 
Systems Node to hear us report on RMS Node updates and accomplishments 
during the past year, and for us to solicit your feedback regarding 
how we should proceed. 
 
Those attending the DPS Meeting are welcome to join us in person. 

For remote attendees, the Zoom coordinates and agenda will be sent by 
email. To be added to our list, please contact Matt Tiscareno 
(matt@seti.org).

[NASA] PDS: ARTEMIS II MISSION DATA RELEASE

The NASA Planetary Data System announces the release of the data
archives from the Artemis II mission. Artemis II was a crewed flight 
test to demonstrate that the Space Launch System (SLS) rocket and the 
Orion spacecraft could safely support human life in deep space beyond 
low Earth orbit. Orion launched April 1, 2026 and splashed down in the 
Pacific Ocean on April 10, 2026.

This release contains source, raw, processed, derived, browse, and 
document products from the mission: crew handheld camera images, Orion 
vehicle camera images and video, mission audio with transcripts and 
crew annotations, Orion storage locker temperature and humidity data, 
mission documents, and SPICE kernels. The data are archived at various 
PDS nodes.

Mission documents and Orion environment data at the Geosciences Node 
Crew camera, Orion camera, and mission audio data at the Cartography 
and Imaging Sciences Node SPICE data at the NAIF Node

The data may be accessed at:

https://pds-geosciences.wustl.edu/missions/artemis2/index.htm

Or for a bundle-oriented view:

https://pds.nasa.gov/datasearch/subscription-service/SS-20261007.shtml

Images acquired by the crew with the Apple iPhone 17 are not included 
in this delivery and will be archived at a later date.

New Horizons continues its operation, now at 65au from the Sun. Since 
2015 it has made ground-breaking discoveries of the Pluto-Charon 
system, flown past the small contact KBO binary Arrokoth and collected 
phase and light curve data for some three dozen additional KBOs and 
the ice giants. It has also been sampling dust density throughout the 
Solar System and studying the cosmic optical background. Please join 
us for our spotlight webinar this week (30 min, fourth week each 
month), or watch recorded at your convenience.

Our speaker will be Parisa Mostafavi (JHU/APL) and she will be 
speaking on:
