  1. Agency Update ILWS: History Madhulika Guhathakurta NASAHeadquarters Science Mission Directorate Heliophysics Division ILWS WG, Beijing, China, August 27-September 3, 2011

  2. Overarching Principles 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.

  3. Heliophysics: (aka Science of Space Weather & Climate) 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.

  4. System of Systems Surveillance

  5. Heliophysics and Space Weather (SWx) • Heliophysics research provides Theory, Data, and Modeling development at services to the national efforts in operational SWx. • The five research missions most often utilized are ACE, SOHO, STEREO (ahead and behind spacecraft) and SDO Anticipated NASA flt Systems 2012

  6. Heliophysics and Sun-Climate galactic cosmic rays solar dynamo solar energy output comparable to man-made energy solar wind near UV VIS IR radiation space weather 0.0003 Wm-2 Xrays EUV radiation energetic particles heliosphere & IMF UV radiation electron aurora III 0.06 Wm-2 0.003 Wm-2 thermosphere ionosphere magnetosphere 15.4 Wm-2 energetic particles mesosphere & lower thermosphere 0.0000007Wm-2 1366 Wm-2 stratosphere & ozone climate A very important part is the study of the connection between the regions and how one drives a response in another.

  8. 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.

  9. SPP Accomplishments • Science Investigations Selected on Sep. 2, 2010 • FIELDS Experiment: PI – Stuart Bale, University of California Space Sciences Laboratory in Berkeley, CA • Solar Wind Electrons Alphas and Protons (SWEAP) Investigation: PI – Justin C. Kasper, Smithsonian Astronomical Observatory in Cambridge, MA • Wide-field Imager for Solar PRobe (WISPR): PI – Russell Howard, Naval Research Laboratory in Washington, DC • Integrated Science Investigation of the Sun (ISIS): PI – David McComas, Southwest Research Institute in San Antonio, TX • (EPI-Hi – JPL and EPI-Low – APL) • Heliospheric Origins with Solar Probe Plus: PI – Marco Velli, NASA Jet Propulsion Laboratory in Pasadena, CA • Mission Observatory Scientist

  10. Major Milestones • Mission Design Review – October, 2011 • Preliminary Design Review – January 2014* • Critical Design Review – November 2015* • Integration and Testing start – August 2016* • Pre-Environmental Review – July 2017* • Pre-Ship Review – May 2018* • Launch Readiness Date – August 2018 • End of Mission – September 2025 * Preliminary and subject to change

  11. 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.  Space Weather Week: in Boulder, April 25-28, 2011 SWEF on June 21st Theme: "Here comes the Sun! National Space Weather Priorities to prepare for Solar Maximum"

  12. 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.

  13. 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'.

  15. 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.

  16. 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. From Here to 2022 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.
