This program element is for the Heliophysics Environmental and Radiation Measurement Experiment Suite (HERMES) Interdisciplinary Science (IDS) Teams that propose investigations that address HERMES Objectives (Section 1.2) using data products from HERMES and from other sources. Proposed Interdisciplinary Science objectives beyond the HERMES objectives are allowed so long as they complement the HERMES Objectives, including those of the sister payload ESA’s Radiation Sensor Array (ERSA) – see Section 1.3. Investigations focused on theory and modelling are encouraged.
HIDS is a component of the Heliophysics Research Program and proposers interested in this program element are encouraged to see B.1, The Heliophysics Research Program Overview for Heliophysics-specific requirements. Common requirements for all ROSES elements and proposals are found in the ROSES Summary of Solicitation and the 2020 NASA Guidebook for Proposers. The order of precedence for proposers is the following: ROSES Element B.18 (this document) takes precedence followed by B.1, The Heliophysics Research Program Overview, followed by the ROSES Summary of Solicitation and, finally, the Proposer’s Guidebook. Proposers should be familiar with all of these resources.
This program element solicits proposals for HERMES Interdisciplinary Science Teams (HIDS) that will conduct science investigations addressing the HERMES science objectives and additional science objectives enabled by HERMES observations at Gateway, using HERMES data products. Other data sources are allowed. These investigations should have as one of their goals the timely production of results of importance to HERMES.
The science objectives of the HERMES payload take advantage of the Near-Rectilinear Halo Orbit around the Moon to be utilized by Gateway and the presence of the two THEMIS/ARTEMIS spacecraft in equatorial lunar orbit. With this triad of observing points of HERMES and ERSA, and the two THEMIS/ARTEMIS spacecraft, investigations of solar wind dynamics are possible at scales not currently available. Furthermore, in coordination with other spacecraft in Geospace, investigations at lunar distances are possible as the Moon traverses Earth’s magnetotail. The science goals and objectives of the HERMES payload are fully consistent with the NASA Artemis Program.
