1) Second Planetary Decadal Survey Newsletter Available

Steven Squyres, chair of the National Research Council's Planetary
Science Decadal Survey, has posted the second of his planned series of
community newsletters on the survey's website. The newsletter is
available at

2) Planetary Decadal Survey Panel Appointed

The National Research Council has appointed Ellen Stofan (Proxemy
Research), Philip Christensen (Arizona State University), Joseph
Veverka (Cornell University), Heidi Hammel (Planetary Science
Institute) and John Spencer (Southwest Research Institute) as,
respectively, the chairs of the Inner Planets, Mars, Primitive Bodies,
Giant Planets and Satellites panels of the Planetary Science Decadal
Survey. Additional details about the panels and their memberships can
be found at

3) Call for Abstracts for Decadal Survey Session at Fall AGU Meeting

The Planetary Science Decadal Survey is organizing a scientific
session at the Fall AGU meeting entitled “Recent Results in Planetary
Science and Their Impact on Future Science and Mission Priorities”
for details). Members of the geosciences, planetary sciences and
astrobiology communities are encouraged to submit abstracts focusing
on recent discoveries from solar system exploration missions and
associated ground based activities that will likely inform decisions
concerning spacecraft missions to be undertaken during the period
2013-2022. The session conveners are specifically looking for
abstracts that: 1. Focus on results announced since 2002; 2. Explain
why these results are significant relative to current solar system
goals/priorities; and 3. Outline how these results should influence
the next generation of solar system exploration missions. Abstracts
will be accepted from 30 July until 3 September (see for details).

Additional information about survey's goals, organization, activities
and meeting dates is available at



Members of the planetary science and astrobiology communities are
strongly encouraged to draft white papers and submit them via the
decadal survey’s website. See for

1) Site for announcement of planned white papers

To assist the decadal survey plan for the handling, distribution and
best use of the white papers submitted, authors are strongly
encouraged to make use of the white-paper proposal site established by
the Lunar and Planetary Institute:
Use of the LPI site tells the decadal survey what it can expect to
receive and it allows you to accrete coauthors. Remember that broad
community participation is one of the hallmarks of a decadal survey
and that consensus is compelling. More information about the
planetary science decadal survey can be found at

Members of the planetary science and astrobiology communities are
strongly encouraged to draft white papers and submit them via the
decadal survey’s website. See for

2) Primitive Bodies White Papers Sought for Decadal Survey

On behalf of the NASA Small Bodies Assessment Group, anyone interested
in the future study of near-Earth objects, asteroids, comets, dwarf
planets, centaurs and irregular TNOs, interplanetary dust and
irregular satellites are invited to go to

and register to participate in community white papers covering these
topics. Subdiscipline white papers must be completed by September 4 to
accommodate the meeting schedule of the primitive bodies discipline
panel of the decadal survey. This will be followed, over the following
month, by an open discussion of priorities across these subdisciplines
online and at special forums, including one at the DPS (schedule
TBD). A non-anonymous poll open to all registrants and a report
summarizing those results will conclude the primitive bodies community
input to the survey. The report, polling data and discussion records
will be forwarded to the decadal panel before their second meeting in

You are also encouraged to go to the SBAG website

and fill out the Indication of Interest Form to keep updated with the
latest meetings and opportunities to input to NASA planning in the
area of small bodies science.

3) MARS Polar Science White Paper Solicits Coauthors

Dear Colleagues, We have prepared a white paper for the consideration
of the Planetary Science Decadal Survey promoting the idea of a
subsurface drilling mission focused on paleoclimatology to the north
polar cap of Mars. Deep drilling is one possible approach, but not the
only one. The purpose of the White Paper is to indicate to the panel
the strong community support for such a project. The white paper may
be viewed at:

If you would like to lend your support to this white paper please
reply by email to Michael Hecht ( as

"I would like to be listed as a co-author on the Decadal Survey white
paper entitled "Next Steps in Mars Polar Science."

Thanks for your consideration,
Michael Hecht and coauthors.



On 2009 July 19 at approximately 13:30 UTC, Anthony Wesley was
observing Jupiter from his home observatory just outside
Murrumbateman, New South Wales, Australia. He noted a black mark in
Jupiter's South Polar Region (SPR). This might be due to the impact
of either an asteroid or comet - similar to the impacts of comet
Shoemaker-Levy 9 in 1994, and exactly 15 years later. Antonio Cidadao
of Portugal identified the spot in weak methane-band images,
supporting an impact interpretation. Dr. Glenn Orton (JPL) was at the
NASA IRTF and has tentatively confirmed the singleton impact with
methane-band and continuum IR imaging.

The University of Central Florida in Orlando is collecting images and
other information about this event on the following web page:

We invite anyone with relevant news to contact us. In particular, we
seek pre-impact images to constrain the time of impact, images of the
developing impact site, deep circumjovian imaging that might identify
the impactor, and lists of teams submitting DDT proposals, to
coordinate efforts.
