Title: Heliophysics Research Focus Areas for a new
1Heliophysics Research Focus Areas for a
new Heliophysics Roadmap
A summary of suggested updates to the
current RFA, and some possible outcomes
2There were many, wide ranging suggestions on how
the RFAs might be modified to better reflect an
updated set of heliophysics science goals
- I thought they were basically fine
- The main RFAs are OK, but the sub-questions need
better focus/leave out some important science
questions. - These RFAs contain baffling wording, left out
lttopicgt, and this whole section ltXgt (read, J)
does not define a focused area of scientific
research.
3There were many, wide ranging suggestions on how
the RFAs might be modified to better reflect an
updated set of heliophysics science goals
- I had to read all the sub-questions to reverse
engineer the actual meaning of the specific RFA - This is hopeless, I rewrote all of them.
4F Frontier to Prediction? How about
FUNDAMENTAL SCIENCE
- F1. Understand magnetic reconnection as revealed
in solar ?ares, coronal mass ejections, and
geospace storms. - F2. Understand the plasma processes that
accelerate and transport particles. - F3. Understand the role of plasma and neutral
interactions in nonlinear coupling of regions
throughout the solar system. - F4. Understand the creation and variability of
magnetic dynamos and how they drive the dynamics
of solar, planetary and stellar environments.
5F Frontier to Prediction? How about
FUNDAMENTAL SCIENCE
- F1. Understand magnetic reconnection as revealed
in solar ?ares, coronal mass ejections, and
geospace storms. - Why just in these places?
- Reconnection in the solar wind
- Reconnection in the magnetospheres of outer
planets - SUGGEST AGNOSTIC READING
- Understand the conditions under which magnetic
reconnection occurs, and the consequences
thereof, followed by an appropriate list of
locations, scales, etc. in expanded list of
sub-questions.
6F Frontier to Prediction? How about
FUNDAMENTAL SCIENCE
- F2. Understand the plasma processes that
accelerate and transport particles. - What about - acceleration and transport of
neutral particles, - What about - understand multi-step acceleration
processes. - What about specifically calling out waves and
turbulence in the RFA? - Suggested F2. Understand plasma processes such
as waves and turbulence, which can accelerate
particles and transport mass and energy.
7F Frontier to Prediction? How about
FUNDAMENTAL SCIENCE
- F3. Understand the role of plasma and neutral
interactions in nonlinear coupling of regions
throughout the solar system. - Why nonlinear?
- The sub-questions did not mention coupling the
IMT with the lower atmosphere
8F Frontier to Prediction? How about
FUNDAMENTAL SCIENCE
- F4. Understand the creation and variability of
magnetic dynamos and how they drive the dynamics
of solar, planetary and stellar environments. - This is Heliophysics?
- Where do atmosphere-ionosphere dynamos fit?
- Rewrite to "understand the creation and
variability of the solar dynamos and its
relationship to planetary stellar dynamos".
9H - Our Home In Space Understand how human
society, technological systems, and the
habitability of planets are affected by solar
variability interacting with planetary magnetic
?elds and atmospheres.
- H1. Understand the causes and subsequent
evolution of solar activity that affects Earths
space climate and environment. - H2. Determine changes in the Earths
magnetosphere, ionosphere, and upper atmosphere
to enable speci?cation, prediction, and
mitigation of their effects. - H3. Understand the role of the Sun as an energy
source to Earths atmosphere and, in particular,
the role of solar variability in driving change. - H4. Apply our understanding of space plasma
physics to the role of stellar activity and
magnetic shielding in planetary system evolution
and habitability.

11H - Our Home In Space
- H1. Understand the causes and subsequent
evolution of solar activity that affects Earths
space climate and environment. - RFA is OK but questions are too narrow one
table suggested shortening to"...and subsequent
evolution of solar activity. - H2. Determine changes in the Earths
magnetosphere, ionosphere, and upper atmosphere
to enable speci?cation, prediction, and
mitigation of their effects. - Fails to acknowledge upward propagation of
energy from planetary surfaces/atmospheres that
modifies the planetary space environment
12H - Our Home In Space
- H3. Understand the role of the Sun as an energy
source to Earths atmosphere and, in particular,
the role of solar variability in driving change. - Reads poorly. variability in driving change. ?
- role of SEPs in driving isotopic composition.
- H.3.3 Should simply read How does long
mid-term solar variability affect Earths
climate? - H4. Apply our understanding of space plasma
physics to the role of stellar activity and
magnetic shielding in planetary system evolution
and habitability. - Why is this here?
- Do any HPS proposals ever reference this? It's
OK to leave it in for linkage with planetary
astrophysics or it might be deleted if there is
desire to reduce the number of RFA's.

14Safeguard the Journey of Exploration Maximize
the safety and productivity of human and robotic
explorers by developing the capability to predict
the extreme and dynamic conditions in space. J1.
Characterize the variability, extremes, and
boundary conditions of the space environments
that will be encountered by human and robotic
explorers. J2. Develop the capability to predict
the origin and onset of solar activity and
disturbances associated with potentially
hazardous space weather events. J3. Develop the
capability to predict the propagation and
evolution of solar disturbances to enable safe
travel for human and robotic explorers. J4.
Understand and characterize the space weather
effects on and within planetary environments to
minimize risk in exploration activities.
15J1 J4 could be combined. The distinction
between them is subtle. J4 is very strongly
aimed at Mars exploration--still necessary? J2
J3 contain good science and are clearly written
but their science topics could have also have
been included in F and H entries if J were to
disappear. J2 J3 could be combined, although
the physics involved in "origin and onset"is very
different from "propagation evolution.
16- J4 Impact -- Needs lots of work.... what is
really minimizing risk, and what is fundamental
(and thus should be in F)
