1. Doodle poll poster session results

We had 151 participants in the DPS straw poll concerning whether to
continue to keep posters up all week or to go to just 2 days to give
us more of a choice of less expensive smaller venues. The result was
118 voted for the shorter poster session / less expensive option,
vs. 36 for having posters up a full week. We used this unambiguous
result to save money on the 2011 PSG in Nantes, and we are considering
a wider range of locations for 2012. Thank you also to the members
that additionally took the time to write in comments.

2. DPS Survey

We are conducting a new full DPS survey, which will be open until July
31. You should receieve an e-mail very shortly from
inviting you to participate. If you don't see it, please check your
spam filter.

Many of the questions are the same as in 1995 and 2005– our goal is to
repeat these questions every 5 years to track the continuing evolution
of our division, and to be able to respond to the priorities of our
members. We will repeat the poster session question to test whether
doodle polls give us an accurate picture of the position of our
members, and whether this is a viable means for getting quick
responses to questions that arise with short timescales. It should
take just 10-15 minutes to respond. Your answers will guide future
decisions that we make in terms of allocation of DPS resources
(e.g. support for education and outreach, budget allocated to the
Federal Relations Subcommittee, etc.). Responses to the last survey
influenced NASA R&A decisions.

Results will be reported at the October business meeting.

Candy Hansen, DPS Chair

Exploring the solar system opens up a new frontier for future
generations; it is one of the best things done for the future of all
people on this planet. I am very proud of the accomplishments of the
Planetary Science community and deeply grateful to be a part of
it. Just participating in this most fascinating of all fields is an
awesome responsibility.

The DPS has a central role in maintaining and expanding our
exploration of this and other solar systems. However, at the present
moment we are facing a number of serious challenges.

The first is to repair and expand DPS finances. Our financial state
has been ravaged by the down-turn in the economy and a series of DPS
meetings that have been deeply in deficit. The DPS needs to explore
alternatives to the current division of responsibilities between the
DPS and the AAS for meeting organization, which I believe has resulted
in substantially increased costs. My background in economics, my
experience in meeting organization, my contacts with meeting
organization professionals (Orlando is a major center for professional
meeting organizers) and my success in fundraising for past meetings
will all be assets in finding a resolution to this issue.

Second, the change in NASA's exploration directions will provide a new
collection of opportunities and challenges for Planetary Science. The
DPS needs to be a strong advocate for excellence in exploration and
science as the new plans, infrastructure, and programs are
developed. The DPS Vice-Chair needs to take a leadership role in
providing community input to NASA and Congress and representing (and
defending) DPS members' interests to Congress and the Public, who in
the final analysis are our bosses. These issues include responding
effectively to Congressional concerns about unspent R&A carryover;
advocating strongly for the robotic exploration and the research
programs that underpin what we do and are critical to the future of
the human exploration program; and being an advocate for effective
programmatic infrastructure at NASA Headquarters (where the program
offices are chronically understaffed and overworked to the point where
it stymies decisions and slows research). As a former Economist, a
past member of the DPS Board and a past member of the DPS Federal
Relations Subcommittee, I am already familiar with the people, the
politics, and the cash flow of Washington.

I would be proud to serve the DPS and welcome the opportunity to
represent our community. What we do involves some of the highest and
best aspirations of humanity and it is my goal to see that those
aspirations get translated into tangible progress and real science.



Torrence Johnson is currently the Chief Scientist for Solar System
Exploration at Caltech’s Jet Propulsion Laboratory, Pasadena

He earned his undergraduate degree in physics from Washington
University in St. Louis in 1966 and went on to graduate studies in
planetary science at Caltech, receiving his PhD in 1970. His
dissertation dealt with telescopic observations of the spectral
reflectance of Jupiter’s Galilean satellites. After postdoctoral
studies at MIT, he returned to California as a NRC Research Associate
at the Jet Propulsion Laboratory and became a member of the technical
staff at JPL in 1973. Since then he has worked in many areas of
modern planetary research, including ground based telescopic
observations, laboratory and theoretical studies, and planetary
spacecraft missions. His primary research interests have been in the
geochemistry and geophysics of planetary satellites, the Moon and
asteroids. On the Voyager mission, he played a major role as a member
of the Imaging Science Team, chairing the Satellite Working Group and
planning and analyzing observations of satellites at Jupiter, Saturn,
Uranus, and Neptune. In 1977 he was named Project Scientist for the
Galileo mission and was a Co-I on the Near Infrared Mapping
Spectrometer. During the course of the Galileo mission he directed
the activities of the Galileo science teams, which spectacularly
achieved its primary goals in the Jupiter system and continued with
extended studies of Europa and Io. He is currently involved in ongoing
research into the properties of giant planet satellites as a team
member of the Cassini imaging team and a Co-Investigator on the Cosmic
Dust Analyzer experiment.

Honors and Awards: In the course of his career he has received
numerous awards, including two medals for scientific achievement from
NASA and one for outstanding leadership. His is a member of the
American Academy of Arts and Sciences, and an elected Fellow of the
American Association for the Advancement of Science, the American
Geophysical Union, the International Academy of Astronautics, the
American Association for the Advancement of Science, and the Explorers
Club. He is a member of the IAU. He has an asteroid (2614 Torrence)
named for him in recognition of contributions to asteroid science. In
1997 he received an honorary degree in astronomy from the University
of Padua, where Galileo made his original observations of the
satellites of Jupiter in 1610.

Publications: He has published over 180 research articles as well as
numerous popular articles and book chapters. He is also an editor of
the reference work (with Lucy McFadden and Paul Weissman),
Encyclopedia of the Solar System (Academic Press).

Community Service: He has been a member of numerous NASA advisory and
science working groups, including the Jupiter Orbiter Probe (later
Galileo) Science Working Group, the NASA/ESA joint Cassini Science
Working Group, NASA Space Science Advisory Committee and currently the
steering group of the Outer Planet Analysis Group. He served as the
third DPS Secretary Treasurer (1977-1980), is a past President of the
AGU’s Planetology Section, and has been a Vice-Chair of COSPAR
Scientific Commission B (Solar System) and is the current Commission B


Since its inception, the DPS has played a unique and important role in
providing a focus for planetary researchers of all types from around
the world. It is emblematic of the breadth of the DPS that the
initial organizing committee and early Chairs included luminaries in
such diverse fields as atmospheric science (Chamberlain), meteoritics
and geochemistry (Anders), planetary photometry (Irvine) and exo (now
astro-) biology (Sagan). During the first decade of the new
millennium, the DPS is now playing a leading role in expanding the
study of the origin and nature of planets in our solar system to
planetary systems around other stars. With the advent of increasingly
powerful ground-based and space-based observing facilities and with
spacecraft active at, on the way to, or planned for, virtually every
class of planetary target, never has our science created more
excitement, both professionally and publically. But what of the

A professional organization such as the DPS rests on three pillars:
1. Meetings, to provide the community with a forum for reporting
results and exchanging ideas, 2. Publications, to provide a high
quality vehicle for documenting and reviewing research results, and
3. Communications with the public and government agencies supporting
our science. All three require constant attention and development as
conditions change, and all three face significant challenges in the
coming years. If elected Vice-Chair, I would purpose to work with the
Chair and the Committee to assess the current state of each of these
pillars and develop plans to strengthen them for the future.

In the area of meetings, I am sure the membership is well aware of the
stresses that economic conditions have put on the overall finances of
the DPS, including meetings. The challenge is to conduct vibrant
useful meetings, maintaining opportunities for students, in the
current environment where major scientific meetings have thousands of
attendees, require large, modern conference facilities and can sport
registration fees of $500-1000. Holding the type of meeting that the
membership has come to expect will undoubtedly require more resources
in the future, and probably larger registration fees. The Committee
and the organizers will need to find ways to provide more student
support (along the lines of the Hartmann Student Travel Grants).
Continuing recent innovative efforts to exploit web-based broadcasts
and social networking will also be an important part of enabling the
meetings to serve the needs of the membership. In addition, in a
community such as ours, individual donations of time and resources can
make a big difference. The AGU, for instance, maintains a standing
Development Board to find ways to finance the activities of the Union
that the membership want. While not operating at the scale of the
AGU, I would propose a small committee of DPS members to investigate
ways of promoting more contributions and support from members and
outside sources.

In the publications arena, we have seen many societies and journals
struggle with the rapid transition to electronic publication. Icarus
has its own set of specific problems but is not alone in these.
Indeed electronic publication and new forms of media are changing the
face of nearly every aspect of society as a whole. The DPS will need
to stay current with the changing conditions and business models
affecting electronic publishing generally.

Finally, it is the taxpayers and our governments that support the
science that we do. The DPS has been proactive in supporting outreach
to the public and legislative sectors to explain and promote our
science, but we can do more.

A major element of the Communications pillar is advocating a strong
solar system exploration and research program. This effort is
increasingly international in character, with India, China and Japan
having all begun serious planetary exploration, in addition to the
strong ESA program already in place. In the US, as the current
Decadal Survey approaches completion, the planetary community will
have the responsibility in the coming years to educate the public and
lawmakers about its recommendations and advocate implementation of its
scientific priorities. If elected, an important part of my job would
be to help the DPS and its members vigorously promote an exciting new
solar system exploration program for the coming decade and the
required investments in education, research and data analysis needed
to sustain major advances in understanding our (and other) planetary

The DPS is the professional society with which I feel most closely
identified and defined as an active planetary scientist. As a newly
minted Ph.D., I joined the DPS at the time of its founding, and over
the years have served in all the elected offices, starting with the
Committee in 1974. I do not propose to repeat the entire cycle again,
but I feel that I can bring the useful perspective of a senior
scientist to the Committee again beginning in 2010, and I am again
eager to serve this venerable organization for which I have such
respect and warmth of association.

As a NASA employee for nearly 23 years, I have seen a strong and
troubling shift in the agency's view of Civil Servant scientists
employed at the various NASA centers. This is not an issue that can
be solved by the DPS or the community of planetary scientists, but it
is important for the community to be aware of the changes and make
appropriate accommodations in their career choices. At the same time,
R&A funding remains critically deficient at NASA; it would also
benefit from a increase at the NSF. As research scientists and as
educators of future generations of our own kind, we need to discuss
openly the issue of the volume of new scientists we release into the
wild every year. Cuts in university faculty positions across the
country and in Europe, as well as a paucity of post-doc positions, add
to the strain on our profession. Yet, the pace of extraordinary
discoveries in planetary science not only continues, but expands with
every passing year, and there is no end in sight. I would like to
explore ways in which the DPS can foster focused discussion of these
issues so that when opportunities might arise to influence (or at
least inform) policy decisions at the federal level, we are prepared.

Over the last few years, I have felt that the DPS membership at large
is essentially unaware of the issues and discussions that occur in the
Committee, both at the annual meeting and throughout the year. The
DPS newsletter edited and issued by John Spencer is an enormous asset
to the society, but I would like to know more about the nuts and bolts
of DPS organizational issues as they arise and as actions and
decisions are taken. Accordingly, the principal plank in my candidacy
for the Committee is the issue of information and openness in the
internal operations of the DPS, insofar as is possible and practical.
Attendance at the annual business meeting suggests that not all
members are as interested in these matters as I am, but I have a
practical solution to propose. As a DPS Committee member, I would
prepare brief reports on issues under discussion to the membership as
needed, to be distributed as part of the DPS newsletter, after having
them screened by the Chair and other Committee members. As a member,
I know that I would appreciate an occasional report "from the
discussions of the Committee". Two items that I would especially like
to know more about concern the unexpected and debilitating cost of the
Ithaca meeting, and the stance of the DPS vis-a-vis Icarus and
Elsevier. There may be other issues of gravity known to the
Committee, but that might also be usefully discussed openly by the
membership at large. I would like to help encourage and facilitate
such discussion, insofar as it might affect our profession and our
premier professional society.



Andy Rivkin is currently a Senior Staff member at the Johns Hopkins
University Applied Physics Laboratory, a position he has held since 2005.
His work focuses on asteroids, ranging from infrared spectroscopic
observations and modeling of volatiles to leading and participating in
mission studies. His interests extend to other small bodies like comets,
TNOs, and planetary satellites.

He received his BS degree from MIT in 1991 in Earth, Atmospheric, and
Planetary Sciences, following that with his PhD in 1997 from the Planetary
Sciences department at the University of Arizona. In between his time in
Arizona and Maryland, he returned to MIT as a Research Scientist.

Andy has served numerous times (as have we all) as a reviewer for NASA and
NSF proposals as well as journal manuscripts. He led the Science Organizing
Committee for the 2008 Asteroids Comets Meteors meeting in Baltimore and
served as a guest editor for the Meteoritics and Planetary Sciences special
issue resulting from that meeting. He is a member of the Planetary System
Science MOWG, and served as a member of the Characterization Committee for
the 2006 NASA NEO study. From 2004-2007 he was a member of the DPS
Nominating Subcommittee, leading the group in 2007. In addition to being a
DPS member, he is also a member of the AAS and Meteoritical Society.

When not doing science, Andy is likely to be watching baseball or noodling
on his guitar, or both.


The DPS faces a number of challenges and new opportunities in coming years.
The continuing growth of the field of planetary science makes it difficult
to see how to maintain meetings with talks of a reasonable length and a
minimum number of parallel sessions, while minimizing reassignments from
talk requests to posters. There is understandable concern among many
members that the DPS meeting experience will change. One possible avenue is
to take fuller advantage of social media and the internet. The promise of
webcasting meetings was glimpsed at the Ithaca meeting, along with a sense
of the learning curve we face. Podcast presentations, virtual conferencing,
and on-line meetings are ideas the DPS membership, with the guidance of the
committee should continue to examine.

In tension with the meeting-related concerns, there are excellent reasons to
continue to expand the breadth of DPS membership, whether strengthening
newly formed links with the exoplanet community or (re)forging links with
the Mars and lunar communities. As the largest group of U. S. planetary
scientists, and in light of our political activities, we should strive to
include all those who identify as planetary scientists. On this point the
DPS might consider having mini-members meetings at the LPSC, AGU, or
Meteoritical Society meetings (for instance) where possible, to update
non-member planetary scientists on our activities and to demonstrate our
advocacy for the entire field.

These are just a few possible roads to take. While it is not obvious how
best to solve these problems (otherwise it’d already be done!) it is
important that the DPS committee continue to build effective lines of two
way communication with the DPS membership. I look forward to the opportunity
to try and help our society move forward either as part of the DPS
Committee, or by continuing my current role as an active DPS member.

Today, the DPS is the preeminent organization for planetary science in
the world. Throughout my career, I have greatly benefited from
attending its meetings and from countless interactions with its
members. It would be an honor to serve the planetary science community
by being elected to the DPS committee. If elected, I will work to
improve the scientific collaboration, education and public outreach
that are the foundations of our Division. Below are three areas I see
as priorities for DPS in the near future.

First, I believe the face-to-face meetings and personal interactions
that occur at the DPS meetings are invaluable. To keep this
opportunity available to the greatest number of our members it is
important to keep the costs of attending DPS meetings reasonable. This
may result in some difficult decisions about the format or venues of
future meetings. These decisions should be made in a transparent
manner with the full input of the community.

Second, as the DPS grows, multiple parallel sessions are likely to
become the norm at our annual meetings. To facilitate our members
seeing all the talks in which they are interested, I will work to
include webcasts of the meeting, similar to what was done for the 2008
DPS meeting in Ithaca, NY. In particular, I believe it would be a
great resource to the community if, given the speaker’s permission,
the talks could be archived and accessed by DPS members at some later
time. Who among us hasn’t missed a relevant talk because they were in
another session or learned of a particularly good talk only after the

Third, affordable journal access is vital to the exchange of ideas and
cross-pollination that an interdisciplinary field like planetary
science requires to thrive. The discounted subscription to Icarus
available to DPS members is a significant benefit in this regard.

In light of the recent financial difficulties of the Division, all of
these goals must be accomplished in a way that keeps the DPS strong
and in good financial health. If our ambitions exceed our means, we
must (hopefully only temporarily) scale back those ambitions. Thank
you for the honor of being nominated in this election.

There are currently many challenges facing the DPS, especially in
these difficult economic times when, moreover, the gap between the
public and the scientific community in general appears to be ever
increasing. We need to address a wide variety of problems, ranging
from the logistics of the increasing size of the annual DPS meeting to
the long-term impact the paucity of Pu-238 will have on Solar System

It is, of course, excellent that attendance at our annual meetings
continues to grow, and there is much we can do to address the
accompanying logistical complications. The challenge is to preserve
the high level of scientific interaction we all look forward to at DPS
meetings while adopting changes that will help keep costs manageable
(e.g. potentially adjusting the amount of time for posters to be
displayed). Furthermore, finding ways to incorporate new technologies
such as webcasting, as was demonstrated at the 2008 meeting at
Cornell, will help to broaden participation further by making it
possible for people who might be prevented from traveling to the
meeting to participate remotely. It is important that we make our
annual meetings and the resources we have as a community as accessible
as possible, especially to younger scientists for whom travel costs
can be particularly prohibitive. I would work to find more avenues to
encourage involvement of young scientists in DPS activities and to
keep them involved.

As our numbers have grown so has the diversity of our membership, in
large part the result of substantial efforts that have been dedicated
to providing support for underrepresented groups. There is still a
need to work to identify and remove barriers to participation by those
who all too frequently "leak" out of the pipeline. I would look for
opportunities to expand existing programs and develop new ones for
mentoring, professional development, and networking among scientists
at all levels in our community. I would also work to strengthen and
increase participation in public outreach projects to communicate the
significance and the excitement of our diverse projects to as wide an
