Heliophysics System Observatory Connect (ROSES 2019)

Funding Agency:
National Aeronautics and Space Administration

The goal of the Heliophysics System Observatory (HSO) Connect program is to enhance the scientific return of the HSO by supporting investigations that innovatively connect observations from one or more HSO missions with spacecraft or ground-based observations from other SMD Divisions, and/or other agencies within or outside the U.S. This instance of HSO-Connect focuses on observations from the Parker Solar Probe (PSP) mission together with other observations throughout the whole heliosphere. This includes data from currently operating space missions and ground-based observatories, and can include data from missions or observatories not yet launched or operational, but expected to be operational within the time interval of awards from this competition. In addition to PSP observations, investigations can include, but are not limited to, any HSO mission, but also Solar Orbiter, Bepi-Colombo, the Daniel K. Inouye Solar Telescope (DKIST) for example. In order to include observations not yet available, NASA Heliophysics is relaxing the requirement that all data must be in a public archive ahead of proposal submission (see Section 3.4.3 Limited Risk Waver).

Key elements for achieving this goal are advanced planning of coordinated observing campaigns, integration of data analysis activities, and modeling/simulations of the Sun, the heliosphere, geospace, planetary space environments, and the interstellar boundary. HSO-Connect (HSO-C) is intended to support science that cannot effectively be done by individual investigators but that requires a team effort, coordinating observations and using state-of-the-art tools to advance Heliophysics science. Proposals should be ambitious, should include the full range of expertise needed, but also need to be focused enough to be achievable within the lifetime of the award.

HSO-Connect is a component of the Heliophysics Research Program and proposers interested in this program element are encouraged to see the overview of the Heliophysics Research Program in Appendix B.1 of this ROSES NASA Research Announcement.
