1. Imager for Magnetopause-to-Aurora Global Exploration IMAGE Senior Review Presentation July 9, 2001 Reprise for Yosemite February 8, 2002 pre-1981 1981 (DE-1/SAI) J. L. Burch, Principal Investigator (SwRI) T. E. Moore, Project Scientist (NASA/GSFC) P. H. Reiff, Co-Investigator (Rice Univ.) 2000 (IMAGE/EUV) “The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.” - M. Proust

2. IMAGE Senior Review Presentation • July 9, 2001 Purpose of the Senior Review: Allocate scarce MO&DA resources for missions. Strong impetus to turn off missions whose additional science is not as cost-effective Winners: IMAGE, Cluster Loser: IMP-J

3. IMAGE Senior Review Presentation • July 9, 2001 The extended IMAGE mission focuses on geomagnetic activity during the declining phase of the solar cycle. The evolution of the IMAGE orbit provides a new, mid- and low-latitude and ultimately southern hemisphere viewing perspective.

4. IMAGE Senior Review Presentation • July 9, 2001 The sunspot cycle has passed a double peak, and the magnetic field flip. It should be on its way down now. But CIR storms and major storms can still occur (like Aug 1972)

5. IMAGE Senior Review Presentation • July 9, 2001 Prime Mission (2000-2002) Extended Mission (2002-2005) • solar maximum • declining phase of the solar cycle • high-latitude, northern hemisphere viewing • mid- & low-latitude, southern hemisphere viewing (e.g. plasmasphere refilling, RC pitch angle hanges)

6. IMAGE Senior Review Presentation • July 9, 2001 Extended Mission (2005) Perigee over the Northern hemisphere Allows good correlation With ground-based instrumentation And VLF propagation Experiments; excellent aspect for ENA imaging •

7. IMAGE Senior Review Presentation • July 9, 2001 Specific studies to be undertaken during the new mission include: Solar Cycle Dependence of Ionospheric Outflow Magnetic Field-aligned Plasma Dynamics Dynamics and Structural Changes in the Magnetopause and Cusp Cusp Plasma Injection Field-aligned Densities and the Closed Field Line Length over Substorm Time Scales Ring Current Pitch Angle Distributions; storm dynamics Substorms versus storms; convection jets and eddies Plasmasphere Refilling Dynamics High-resolution Ionospheric Imaging Most of these studies are made possible by the new viewing perspective that results from the precession of the IMAGE orbit to middle and low latitudes. Open data policy encourages collaborations with other missions and new initiatives from non-team members (Guest Investigators and others).

8. IMAGE Senior Review Presentation • July 9, 2001 Geomagnetic Activity at Solar Max vs. during Declining Phase of the Solar Cycle How does the inner magnetosphere respond to CIRs? How does a cooler exosphere affect polar ion outflow? Bastille Day Storm, 15-18 July 2000

9. IMAGE Senior Review Presentation • July 9, 2001 Examples of New Science Results Since Proposal Submission

10. IMAGE Senior Review Presentation • July 9, 2001 IMAGE provides first global look at substorm tail dynamics. Sun contamination Dipolarization and injections reach geosynchronous. Auroral onset. Injection complete Stretched tail field. Dense plasmasheet Ions drift earthward in dipolarization E-field faster than they can be replenished from tail convection field Flux increase due to conservation of adiabatic invariance

11. IMAGE Senior Review Presentation • July 9, 2001 IMAGE/RPI’s ability to observe ducted echoes makes possible the determination of field-aligned densities and field-line length and topology, including refilling after drainage.

12. IMAGE Senior Review Presentation • July 9, 2001 IMAGE discovers source of kilometric continuum radiation. EUV imager observes previously unknown “bite outs” in plasmasphere. RPI demonstrates that kilometric continuum is generated deep within bite outs and is beamed along magnetic equator from a confined source region.

13. IMAGE Senior Review Presentation • July 9, 2001 IMAGE sounds the magnetopause - putting “M” into IMAGE. . RPI observes the magnetopause echoes (getting farther away) while the plasmapause echoes become closer.

14. IMAGE Senior Review Presentation • July 9, 2001 IMF Dependence of Subauroral Proton Emissions: the “Q” Aurora

15. IMAGE Senior Review Presentation • July 9, 2001 In addition to its investigation of the geospace environment, IMAGE will continue to exploit LENA’s unique capability to observe solar wind and interstellar neutrals. Specifically, IMAGE will: Study seasonal and solar cycle variations in solar wind neutral flux Search for ENAs formed by charge exchange between solar wind ions and interstellar neutrals, and as interaction between the solar wind and exosphere - magnetosheath! Determine the angular width and start and stop dates of the interstellar neutral signal observed between late December and early February Although primarily a magnetospheric mission, IMAGE contributes to understanding of how the Sun and the galaxy interact (Quest III, SEC Roadmap 2000).

16. IMAGE Senior Review Presentation • July 9, 2001 IMAGE detects solar wind and interstellar neutrals.

17. Seasonal variation of solar wind neutral atoms as probe of gas and dust in the inner heliosphere Theory: Hydrogen Flux at Earth Theory: Years after Solar Maximum

18. IMAGE Senior Review Presentation • July 9, 2001 New Questions, areas of research: PMEC: polarization fields making major changes in ENA location, localized E-fields make biteouts or shoulders Q-aurora: low-altitude evidence of plasma tail, drainage plume? DUCTS: Evidence of wrapped-up plasma tails?? CUSP ACCELERATED IONS: need to nail that down ANTIPARALLEL RECONNECTION: how resolve the IMAGE results with other low latitude results that look more like component merging? RING CURRENT/Plasmasphere interactions

19. And many many many more exciting results that have been presented in this meeting!! Years after Solar Maximum

20. IMAGE Senior Review Presentation • July 9, 2001 IMAGE provides real-time auroral imaging to the NOAA Space Environment Center.* http://www.sec.noaa.gov/IMAGE/ Given the importance of the plasma drainage tail, Maybe we should also have EUV data realtime! (Foster’s report this meeting) *IMAGE will provide critical extended auroral imaging that Polar will lose once its fuel is depleted.

27. IMAGE Senior Review Presentation • July 9, 2001 The IMAGE extended mission addresses three of the four fundamental quests set forth in the 2000 SEC Roadmap. Quest II. How do the planets respond to solar variations? IMAGE provides nearly continuous global imaging of the solar-wind magnetosphere interaction at solar maximum and, during an extended mission, during the declining phase. Quest III. How do the Sun and galaxy interact? IMAGE obtains measurements of interstellar neutrals and is conducting a search for neutral atoms produced at the termination shock. Quest IV. How does solar variability affect life and society? As the first space weather satellite, IMAGE provides the only global monitor of space weather. And the IMAGE extended mission offers an effective and imaginative approach to the SEC E/PO goals described in the Roadmap.

28. Keep up the good work!!
