5Project Prometheus Overview
- Safety is the absolute highest priority
- Key components of Project Prometheus
- Radioisotope power systems development
- Nuclear propulsion research
- Jupiter Icy Moons Orbiter (JIMO) development
- Project Prometheus is in addition to the In-Space
Propulsion Program already in the baseline
Project Prometheus will enable a new strategic
approach to planetary exploration and is
likelyto play a key role in NASAs future
6Space Propulsion Power
- Today (chemical propulsion radioisotope power)
- Launch, then coast
- Constricted ability to operate science
instruments (power limits) - Constricted ability to transmit science data to
Earth - Constricted launch opportunities due to gravity
assists - Cannot orbit multiple moons of outer planets
- Limited to fleeting observation from flyby
- Cannot change target mid-mission
- Future (nuclear electric propulsion)
- Much greater ability to change speed
- Much greater (practically unlimited) power for
instruments - Vastly greater ability to transmit science data
to Earth - No launch constraint to use gravity assists
- Can orbit multiple objects or moons
- Vastly greater, persistent observation time
- Can change target mid-mission (to support change
in priorities)

Communication
13What is Risk?
- RISK
- Probability of a Hazard
- X
- Impact of the Hazard Occurring
14What is Risk Communication?
Risk Communication is not Telling people what we
want them to know, in order to get them to behave
rationally, that is, the way we think they
should behave.
15What is Risk Communication?
- A defined by the Society for Risk Analysis An
interactive process of exchange of information
and opinion among individuals, groups, and
institutions often involves multiple messages
about the nature of risk or expressing concerns,
opinions, or reactions to risk messages or to
legal or institutional arrangements for risk
management. - Our working definition The method by which the
public can be informed as to the potential risks
and benefits of specific projects and programs. - Risk communication deals with all written and
verbal external communication with the media,
public, interest groups, Congress, and other
government agencies regarding NASA missions or
programs that are controversial or related to the
controversial aspects of a mission or program
16Risk Communication is Based on Perception of Risk
- Risks Perceived to
- Be voluntary
- Be under an individuals control
- Have clear benefits
- Be distributed fairly
- Be natural
- Be statistical
- Be generated by a trusted source
- Be familiar
- Affect adults
- Are More Accepted Than
- Risks perceived as being imposed
- Risks perceived to be controlled by others
- Risks perceived to have little or no benefit
- Risks perceived to be unfairly distributed
- Risks perceived to be manmade
- Risks perceived to be catastrophic
- Risks perceived to be generated by an untrusted
source - Risks perceived to be exotic
- Risks perceived to affect children
Understanding the perception of a risk is key to
creating effective Risk Communication products
and opportunities
17Developmental Stages in Risk Communication
- All we have to do is get the numbers right
- All we have to do is tell them the numbers
- All we have to do is explain what we mean by the
numbers - All we have to do is show them that theyve
accepted similar risks in the past - All we have to do is show them that its a good
deal for them - All we have to do is treat them nice
- All we have to do is make them partners
- All of the above

Communication Unplugged Twenty Years of
Process, Journal of Risk Analysis, 15137-45
(1995).
18Risk Communication Can Fail Because
- On a personal basis
- It doesnt take into account the psychological
basis for the perception of risk - It fails to recognize why people respond to risks
the way they do. - It refuses to accept that this irrational
behavior is how humans are programmed to try to
protect themselves - Perception of risk is hardwired and we cant
help it its how we, as a species, survived - It has the goal of making everyone see the risk
as the communicator sees it - Decide-Announce-Defend or Just-the-Facts-Maam
approaches dont work
19Risk Communication Can Fail Because
- On an organizational basis
- It is not done proactively, but only after a
problem has arisen and public responses and ideas
have already formed - It is a lecture, not a conversation
- It is done by people with a vested interest that
conflicts with the audience, so it appears that
the facts cannot be trusted - It focuses solely on the facts and the facts
are not the cause of the controversy
Crisis Heightened public emotions Limited
access to facts Rumor, gossip, speculation,
assumption and inference An unstable
information environment. US HHS 2002
Communicating in a Crisis Risk Communication
Guidelines for Public Officials
20Risk Communication Can Be Successful if
- It accepts that the dialogue sometimes may be
more about feelings than facts - Information is shared and concerns acknowledged
- All sides appreciate diverse opinions and
perspectives in an atmosphere of consensus
building - If the communicators are proactively prepared and
understand their role - Consistent messages, open and accountable
processes, and a solid understanding of the
importance of good risk communication are
important.
21Keys to Good Risk Communication
- Before Controversy Develops
- Determine and coordinate the messages
- What information is crucial to convey and are the
messages different prior, during or after an
event? - What are the obstacles to effective
communications and how can they be minimized? - Ensure that spokespersons are identified and
prepared - What are the opportunities for effective
communications and how can they be maximized? - What is the environment into which we are
introducing information? - Who are the audiences and what are their
attitudes? - Engage the public and media in a long-term
coordinated dialogue, using a variety of formats - What questions can we anticipate from the public
when we communicate risk messages? - What are the new medias responsibilities and how
can we help reporters meet them? - How can we come to understand our audiences?
22Risk Communication Components
- The Risk Message
- A written, verbal, or visual statement containing
information about risk may or may not include
advice about risk reduction behavior a formal
risk message is a structured written, audio or
visual packaged developed with the express
purpose of presenting information about risk. - Ease public concern
- Stay on Message
- Deliver Accurate and Timely Information
- US HHS 2002 Communicating in a Crisis Risk
Communication Guidelines for Public Officials
23Risk Communication Components
- The Risk Communicator
- The individual or office sending a risk message
or interacting with other individuals, groups or
organizations in a risk communication process
may also be the risk manager, the risk message
preparer, risk analyst or other expert - Use consistent names and terms
- Avoid acronyms and jargon
- Carefully consider the use of visuals
- Answer not only the question how much? but also
will it hurt me? to ensure the information is
relevant - Use familiar frames of reference
- US HHS 2002 Communicating in a Crisis Risk
Communication Guidelines for Public Officials
24Risk Communication Components
- Acknowledge Uncertainty
- If information is not known or not available,
admit it - I dont know can actually build credibility
- Provide as much information as possible
- Demands for 100 certainty are more likely based
on underlying values and process, not the
science. Try to identify the real concerns behind
the demand - Understand the Public Perceptions of Risk
- Key barrier is the term risk how it is
measured, described, and ultimately received - People do not believe that risks are of the same
type, size or importance - Perception of risk for the technical and lay
audiences are often dissimilar - US HHS 2002 Communicating in a Crisis Risk
Communication Guidelines for Public Officials
25Conclusion if risk communication is successful
- Institutional and interpersonal trust could be
increased - Controversies could be reduced in length,
strength or frequency - Frequency or magnitude of lawsuits could be
reduced - Programmatic success could become more achievable

27Why is NASA Doing This?
- Public attitudes toward NASAs use of space
nuclear power have changed - Pre-Challenger few concerns, NASAs safety
record unquestioned - Post-Challenger issues over shuttle safety
included concerns about RPS - Galileo, Ulysses and Cassini faced media,
Congressional, and public opposition - Opposition increased with each mission
- Lawsuits filed to stop launches and Earth
swingbys - Letters to White House and Congress, local
editorials, local political actions,
international actions - NASA forced to spend increasing resources
- Sources Sandra Dawson, NASA JPL, Risk
Communication Coordinator, - Victoria Friedensen, Protesting SpaceA Study of
Technology Choice, - Perception of Risk, and Space Exploration
28Why Bother?
- Risk communication, if done right, with a
coordinated message and proactive public
engagement, can - Increase NASAs understanding of what the issues
and concerns are or might be - Reduce misinformation and possible resulting
concern - Increase trust among the public, media, and
local/state/national governments
29A Managed Approach to Risk Communication
- NASA OSS is instituting a set of long-range plans
that will bring risk communication strategies to
mission and program planning - OSS has plans that are either approved or in
review that encompass nuclear power for
spacecraft and planetary protection - OSS as a whole
- Mars Exploration Program
- New Horizons mission
- Project Prometheus
- Jupiter Icy Moons Orbiter
- Project Prometheus is implementing a three-fold
approach - Risk communication
- Public engagement
- Education and public outreach
- The goals of these plans are to increase public
opportunity to learn, reduce controversy, and
increase trust
30Project Prometheus Early Risk Communication
Focus
- Two major areas of prevention
- Saying the wrong thing
- Legal risks
- NEPA and decision making
- Out of context quotes, misstatements
- Bad press can be misquoted, sound uninformed,
appear to be lying, etc. - Not communicating
- Lack of concern perception of arrogance, not
clear, not enough information - Attention to these areas can reduce perception of
risk - Source Sandra Dawson, NASA JPL, Risk
Communication Coordinator
31Risk Communication Goals for Project Prometheus
- Ensure clear, consistent, open, accountable,
quality, communication processes and products by
providing training and skills development for
NASA, DOE, and contractor personnel - Enable extended, inclusive engagement with
stakeholders the scientific community,
environmental and other public interest groups,
Congress, Federal Agencies, the media, and the
public - Develop and expand communications products and
processes to enable public access, public
engagement and inclusive communications
processes, such as internet websites, stakeholder
meetings, public fora, and other opportunities to
engage the interest of the public
32Conclusion
- Project Prometheus will enable a new paradigm in
the scientific exploration of the Solar System - The proposed JIMO mission will start a new
generation of missions characterized by more
maneuverability, flexibility, power and lifetime - Project Prometheus organization is established at
NASA Headquarters where - Risk Communication, Public Engagement, and
Education and Outreach are considered integral
parts of Project Prometheus, and like safety, are
being designed into the program from the
beginning - Risk Communication will become an Agency-wide
function, with training and support provided for
all Project Prometheus teams
