New SMD AA’s Priorities: 

New SMD AA’s 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 R&A 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

Radiation Belt Storm Probes (RBSP) Mission Objective: Gain understanding of how changes in the solar activity and solar wind form or change the relativistic electron and ion populations in the Earth’s radiation belts Organizations: Project Management: Johns Hopkins University/Applied Physics Laboratory (JHU/APL) Spacecraft: JHU/APL Instruments: Energetic Particle, Composition, & Thermal Plasma (ECT): Boston University Electric & Magnetic Field Instrument Suite and Integrated Science (EMFISIS): Univ. of Iowa Electric Field and Waves Instrument (EFW): Univ. of Minnesota Radiation Belt Storm Probes Ion Composition Experiment (RBSPICE): New Jersey Inst. of Technology Relativistic Proton Spectrometer (RPS): National Reconnaissance Office (NRO) Contributed Ground System: Mission Operations, Flight Dynamics – JHU/APL Science Operations – Instrument-provider institutions Test Facilities, Project Oversight, NRO Instrument Delivery: GSFC Mission Description: Two identical spinning spacecraft in 9-hour lapping orbits in the radiation belts. Orbits are 500 x 30,600 km with 10o inclination. Challenges are high radiation environment, deep dielectric discharge, data collection strategy, and electric field emissions. Two-year prime operations lifetime. Launch: EELV from KSC in March 2012 Web site: http://www.lws.nasa.gov/geospace/

Slide8: 

Magnetospheric MultiScale Project (MMS) Mission Objective: Conduct definitive investigations of magnetic reconnection in the boundary regions of the Earth’s magnetosphere. Determine 3-dimensional geometry of the plasma, magnetic fields, and current structures. Organizations: Project Management: GSFC Spacecraft: GSFC Instrument Suite Contractor: Southwest Research Institute (SwRI) Fields - University of New Hampshire Fast Plasma Investigation (FPI) - GSFC Hot Plasma Composition Analyzer (HPCA) - SwRI Energetic Particles Investigation (EPI) - APL Active Spacecraft Potential Control (ASPOC) - donated by Austria Ground System: Mission Operations, Flight Dynamics - GSFC Science Operations - University of Colorado (SwRI subcontract) Mission Description: Constellation of 4 identical spin stabilized satellites flying in tetrahedron formation with 10 to 400s of km separation. Elliptical Earth orbits (~1.2 Re x 20 Re). In situ instruments measure electric and magnetic fields, ions, and electrons. Extensive orbit maintenance and orbit adjust capability. 2-year operational mission. Launch: Four satellites launched together in one EELV from KSC in 2014 Web site: http://stp.gsfc.nasa.gov/

Slide10: 

Solar Probe HUMANITY’S FIRST VISIT TO A STAR - highest priority for a major- Class mission in the 2003 Decadal 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 SYSTEM - AND HOW SOLAR PARTICLES ARE ACCELERATED AND INJECTED IN TO PLANETARY ENVIRONMENTS SCIENTIFICALLY COMPELLING AND TECHNOLIGICALLY SOPHISTICATED MISSION WITH THE FASTEST MOVING SPACE CRAFT EVER AT A SPEED OF .1% THE SPEED OF LIGHT.

Solar Probe-Lite Study(intent only): 

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.

Solar Orbiter/Solar Sentinels: 

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.

Slide13: 

How does the Sun generate the environment of the inner solar system? Primary Objectives: Determine the sources, acceleration mechanisms and 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 and interplanetary magnetic fields.
