of small-, medium-, and large-class missions, and matching these efforts with a robust program of research and analysis and theory and modeling activities that will exploit, complement, add value, and, in effect, extend experimental observations. Further, in order to take advantage of future opportunities, there is an evident need to develop a well-trained workforce The survey committee's recommended core program for heliophysics includes the following elements, in descending order of priority: 1.

Note that the MO&DA augmentation begins in 2016, at a time when the Solar Dynamics Observatory will have moved out of prime mission, adding greatly to data covered by the general guest investigator program. Implementation of the NASA portion of DRIVE ramps up by 2022 to an augmentation to existing program lines that is equivalent to approximately $33 million in current (2013)

The dashed line represents the recommended base funding level for the LWS program, including a 2 percent inflation slope. Funding at the full level occurs near the end of the decade, with a 6-year mission cadence beginning with GDC.

1 accordance with its charge, the survey committee did not reprioritize any NASA mission that was in formulation or advanced In development. In June 2011, the survey committee's charge was modified by NASA to include a request for it to present "decision rules" to guide the future development of the Solar Probe Plus mission.

Nevertheless, fast solar wind streams typical of polar coronal holes will still be adequately sampled, albeit at larger radial distances from the Sun. Only one remote sensing instrument remains on SPP, but the most significant impairment comes from the lack of in situ solar wind composition measurements; the survey committee urges NASA to consider restoring this capability.

Finally, NASA support for the U.S.-Taiwanese FORMOSAT-3/COSMIC microsatellite science mission for weather, climate, space weather, and geodetic research illustrates the range of possible collaborative opportunities that might arise. The augmented Explorer line is the recommended source of funding for participation in most such international collaborations.
