New SMD AAs Priorities

• To advance priorities of Decadal Survey
• To get more from SMD budget (some examples)
• Control mission costs
• More frequent small missions
• International partnerships encouraged
• Revitalize sub-orbital science program
• Streamlined processes inside SMD and for
  grantees
  
• Proposal and funding triage
• Strategic investments in RA and data analysis
  across SMD
  
• Zero-sum adjustments to achieve the above
• To increase communication with the science
  community
  
• To support the Vision for Space Exploration
  through solid science efforts

HUMANITYS FIRST VISIT TO A STAR - highest
priority for a major- Class mission in the 2003 D
ecadal Survey. FIRST GROUND TRUTH CONCERNING
PROPERTIES AND CONDITIONS NEAR THE SUN -
DIRECT CONFRONTATION BETWEEM ASTROPHYSICAL
THEORY AND PHYSICAL MEASUREMENT.
UNDERSTAND HOW OUR STAR COUPLES TO THE SOLAR SYS
TEM - AND HOW SOLAR PARTICLES ARE ACCELERATED AND
INJECTED IN TO PLANETARY ENVIRONMENTS
SCIENTIFICALLY COMPELLING AND TECHNOLIGICALLY SO
PHISTICATED MISSION WITH THE FASTEST MOVING SPACE
CRAFT EVER AT A SPEED OF .1 THE SPEED OF LIGHT.
11
Solar Probe-Lite Study(intent only)

• Intend to perform a study for a mission which
  addresses the implied Goals and Priorities of
  the Decadal survey
  
• Design a mission that can be achieved at a
  notional budget of about half that estimated by
  the JSTDT study for Solar Probe
  
• Candidate trades may include
• Non-Nuclear powered spacecraft,
• Reduced s/c mass,
• Reduced payload capability,
• Review choice of orbit/perihelion,
• and other choices as seen effective.

12
Solar Orbiter/Solar Sentinels

• Elements
• Sentinels LWS future mission, ranked as high
  priority (third for moderate missions) by
  National Research Council in the 2003 Decadal
  Survey.
• Program Future
• US Science and Technology Definition Team report
  complete
  
• Outgrowth of 2nd last Bi-lat Is it possible to
  define a joint Solar Orbiter (ESA) - Solar
  Sentinel Mission that provides scientific and
  programmatic advantages.?
• Joint Science and Technology Definition Team
  finding scientific goals and priorities for a
  combined investigation (next page)
  
• Recent ESA-NASA bilateral went well for the joint
  mission.
  
• The results will be made known shortly by
  the two agencies.

13
Focus of Joint Mission
How does the Sun generate the environment of
theinner solar system? Primary Objectives
Determine the sources, acceleration
mechanismsand transport processes of solar
energetic particles. Determine how coronal mass
ejections evolve from the Sun to the inner
solar system. 3. Determine the origins of solar
wind streams andinterplanetary magnetic
fields. JSTDT Report to be finished by Septembe
r, 2007
