Overarching Principles
NASA Living with a Star Program
Targeted Research & Technology
Steering Committee
At the center of the solar system there is a
magnetic variable star, the Sun, that drives the
Earth and other Planets, and structures
interplanetary space itself .
All of NASA’s activities, all human endeavor,
are subjected to forces in this neighborhood.

Targeted

Steering Committee
Understanding the Sun and its effects on the Earth and
the solar system.
1. This is a complex system with many different temporal
and spatial scales
2. The study of heliophysics involves three forces, and
their interactions: pressure, gravity, and magnetic fields.
3. The Sun is coupled to the planetary system and space
by radiation, charged particles, and magnetic fields.

SDO Accomplishments
 A year after SDO's first light, researchers submitted 191 abstracts to
the first SDO science meeting. This corresponds to a new result
almost every two days--a remarkable output.
Some Highlights!
 Solar flares are more powerful than we thought. EVE data show
that flares produce as much as five times more energy than
previously believed. The extra radiation comes out at relatively long
wavelengths (longer than soft x-ray) that powerfully effect Earth's
atmosphere. The Sun-Earth connection just got 5 times stronger!
 Solar activity is fundamentally global. Solar physicists have long
suspected this. The famous August 1st eruption plus many lesser
examples have extinguished all doubt.
 The Sun is more beautiful than anyone imagined. Many of the
phenomena SDO routinely record have no textbook names. Stories
on SDO continues to be covered by all sorts of news magazines,
science or otherwise.

NSWP Updates
A new strategic plan is available
http://www.ofcm.gov/nswp-sp/2010/NSWP%20StratPlan%20for%20web.pdf
The Grand Challenges for Disaster Reduction is a ten-year strategy crafted by the National
Science and Technology Council’s Subcommittee on Disaster Reduction (SDR).
http://www.sdr.gov/185820_Space_FINAL.pdf
At the request of OSTP NSWP is initiating a new assessment in response to the 2010 NASA
Authorization Act, Section 809. (The Act also requires the Director of the Office of Science and
Technology Policy (OSTP) to submit a report to the appropriate committees of Congress that: "(A)
details the current data sources, both space- and ground-based, that are necessary for space
weather forecasting; and (B) details the space- and ground-based systems that will be required to
gather data necessary for space weather forecasting for the next 10 years)
The plan calls for the formation of a Joint Action Group for Space Environmental Capabilities
Analysis (JAG/SECA) to conduct the assessment.

ISWI
The International Space Weather Initiative was established in
February 2009 to continue the aspects of the International
Heliophysical Year that need long-term support.
It is endorsed by the United Nations, and is supported by the U.S.
State Department, which enables activities in nations that have had
little involvement in space weather science.
ISWI prioritizes collaborations with scientists in areas of the world
that have been underrepresented.
A key component is the instrument program, which forms
partnerships between instrument builders and institutes to host
the instruments. There are currently fourteen instrument arrays
participating in the program (see http://iswi-secretariat.org for a
list of current instrument arrays, and instrument sites).
The data and modeling program operates in a similar way, forming
new partnerships between nations.
Heliophysics Text Books
The sub-disciplines within Heliophysics have a rich variety of available
textbooks, but no textbooks currently exist that present the diverse materials
from their common physical principles, and help teachers well-versed in one
discipline to teach the directly related areas within other disciplines.
Three affordable textbooks will be produced for each year of the Summer
School. The books will be aimed for senior level undergraduates, graduate
students and beginning postdoctoral students in all of the sciences related to
climate physics, space physics, and heliospheric and solar physics, plus
relevant branches of astrophysics and plasma physics. The three textbooks
will cover all of the topics in heliophysics.
NOTE: The Heliophysics textbooks will be published by Cambridge
University Press. All appendices will be online. The physical textbooks will
not have 'numerical modeling descriptions' nor 'problem sets'.

Issues and Challenges
 NRC Heliophysics Decadal Survey Team has been provided with revised
resource boundaries assuming flat budget and impacts of NLS2 contract.
 An augmentation of the Heliophysics Explorer program has a strategic
impact for the national SWx program. NRC Decadal Survey expected to
recommend as a high priority in 2013 report.
 Eroding R&A Funding impacts national research community. Restructuring
of the Research and Analysis portion of the Division is a prime issue for
2011/2012.
 International partnership challenges:
 NLS2 cost increases for launchers is a threat to international
collaboration. US reduces scope of contribution.

From Here to 2022
2012 SWx Contribution by NASA missions includes
the beacon mode data from the newly launched
RBSP,SDO, STEREO, ACE, and the SOHO data
system .
The Mission Data are stored in the VxO, and the
CCMC provides NRT Models from this data. The
R&A and TRT (LWS) develop Theory for inclusion
into new models.
2022 It is possible that some of the missions
of 2012 will be operational, such as SDO and
ACE - but harder to predict the effects due
to age on STEREO, SOHO and RBSP.
The Future of NASA data systems, the NASA
modeling efforts, and the Theory Program
will be influenced by the upcoming (2013)
NRC Decadal Survey.
