Outer Heliosphere Guest Investigators (ROSES 2019)

Funding Agency:
National Aeronautics and Space Administration

The Outer Heliosphere Guest Investigators (OH-GI) program, solicits proposals that focus on analysis of data from Voyager, the Interstellar Boundary Explorer (IBEX), and other space assets that generate data enabling the study of the outer heliosphere. This program is intended to maximize the scientific return from these mature missions by providing support for research beyond presently funded investigations. It may also act to inform future exploration and investigation opportunities of interstellar space. Funded investigators (PIs and Co-Is) of this solicitation will be considered Guest Investigators of Voyager and/or IBEX for the duration of the award and will be invited to attend and present progress at Voyager and IBEX team meetings.

Proposals should address a subset of the Heliophysics Decadal Survey Goal 3 (HDSG3): "Determine the interaction of the Sun with the Solar System and the interstellar medium," focusing only on the interaction of the Sun with the interstellar medium.

The OH-GI program 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.
