SPECIAL SYMPOSIUM "PLANETARY AEROSOLS: FROM EARTH TO EXOPLANETS"

We invite you to join a special symposium "Planetary Aerosols: From
Earth to Exoplanets" at the American Association for Aerosol Research
(AAAR) Conference October 21-25, 2024 in Alburquerque, New Mexico.

We invite submissions from laboratory, observational, modeling, and
instrument/method development work that focus on aerosols in
atmospheres different from that of the modern Earth. A goal of the
session is to facilitate multi-disciplinary connections between
planetary and aerosol scientists. The Symposium Abstract can be found
here:

The regular abstract deadline is May 8, 2024, with late-breaking
posters accepted until July 22, 2024. The conference website,
including links to submission information is at:

MEPAG/EXMAG WORKSHOP ON MARS SAMPLE SCIENCE

Dear MEPAG Community, the upcoming MEPAG/ExMAG Workshop: Connecting
Community Scientific Hypotheses to Mars Sample Science will take place
on April 22-23 in a hybrid format (virtual/Washington, DC). Details are
available on the meeting website:

https://www.lpi.usra.edu/mepag/meetings/mepag-exmag-workshop/

Registration is required for this workshop, whether attending in person
or virtually. Registration for in-person attendance will be available
through April 15, 2024, or when the in-person limit of 100 is reached,
whichever occurs first. There will be no onsite registration.
Registration for virtual attendance will be available through April 21,

LAST CALL FOR THE PLANETARY SOCIETY'S DAY OF ACTION IN WASHINGTON, D.C.
ON APRIL 28-29, 2024

The Day of Action is The Planetary Society's premier advocacy event.
Following a successful return to in-person advocacy in 2023, this
year's event will include a training on Sunday, April 28, and a full
day of scheduled and drop-in meetings on Monday, April 29. The
deadline to register is Monday, April 15!

The Day of Action is an opportunity for members of the community to
take direct action to support space science, research, and
exploration. In-person meetings are the most effective way to defend
science priorities and advance our shared goals. As NASA faces major
budget cuts after Congress already slashed the agency's science budget
in 2024, now is the time to stand united for a robust and balanced
space science program.

Anyone is welcome to participate, whether you're an experienced space
advocate or new to the endeavor. The Planetary Society will provide
you with the training, resources, and scheduled meetings to enable
you to channel your passion and expertise into successful grassroots
advocacy. For more information and to register, go to:

- One to three names of local organizers who will be willing and able
  to join the SOC
- Meeting venue (conference center, university or other institute), A/V
  facilities, seating capacity (at least 100, preferably closer to
  150), space for poster sessions, and amenities (coffee, snacks,
  etc.)
- Level of IT support available
- Expected funding levels to support the conference and expected

mission, the other focuses on moon-magnetosphere interaction and
machine learning.

Closing date May 17, 2024.

Both vacancies can be accessed through this link:

https://www.dias.ie/vacancies/

Prospective applicants are encouraged to directly contact and discuss
scientific opportunities with Dr. Mika Holmberg (mika@cp.dias.ie)
regarding Ganymede's aurora and spacecraft charging position and
Dr. Hans Huybrighs (hans@cp.dias.ie) regarding the moon-magnetosphere
position.

At DIAS, we are committed to building an inclusive scientific
community, distinguished by scientific excellence, gender balance,
and diversity. Proposals for flexible working will be considered.
Applicants are welcome to include in their CV (if applicable) any
career breaks, and a short statement on any impact the Covid-19

TWO OPEN RANK PROFESSORS OF PLANETARY SCIENCES AT THE UNIVERSITY OF
BERN

The Division of Space Research and Planetary Sciences within the
Physics Institute of the University of Bern has two openings, as of
2025, for two professors in experimental planetary sciences. The
Division is one of the leading research groups in the field of space
instrumentation for experimental Solar System exploration and is
looking for professors in the fields of planetary remote sensing and
in situ mass spectrometry or in related fields. The initial hiring
level can range from assistant professor tenure track to full
professor according to qualifications (open rank). The successful
candidates are expected to have or further develop an excellent and
internationally recognized track record in the development,
construction, and exploitation of scientific instrumentation flying on
spacecraft missions. The Division offers excellent conditions in terms
of laboratory infrastructure, engineering, and manufacturing
capabilities to build space-grade hardware. The University of Bern has
set the aim of increasing the percentage of women in leading academic
positions and thus strongly encourages female scientists to apply for
the positions.

The application deadline is 1 August 2024. More information can be
found at:
