2023 Heliophysics Space Weather Vigil Focused Mission of Opportunity (Vigil FMO) Announcement of Opportunity

Background
The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) has released the Announcement of Opportunity (AO) final text for 2023 Heliophysics Space Weather Vigil Focused Mission of Opportunity (Vigil FMO). This AO was generated by the SMD Heliophysics Division’s Heliophysics Space Weather Program to solicit an investigation that includes an instrument(s), e.g., extreme ultraviolet (EUV) imager, to be hosted on the European Space Agency (ESA) Vigil mission. Vigil is a European Space Agency (ESA) Space Safety Programme space weather mission to observe the Sun from the Sun–Earth Lagrange point L5. SMD's Heliophysics Space Weather Program conducts Principal Investigator (PI)-led space investigations and will manage this AO. All Heliophysics Space Weather investigations, including the Vigil FMO, must address NASA’s strategic heliophysics science goals.

Work Details
The 2023 Heliophysics Space Weather Vigil Focused Mission of Opportunity (Vigil FMO) seeks to solicit an investigation that includes an instrument(s), such as an extreme ultraviolet (EUV) imager, to be hosted on the European Space Agency (ESA) Vigil mission. The investigation should advance understanding of solar variability, enable the development of advanced methods for forecasting and nowcasting of solar eruptive events and space weather, make effective use of ESA’s Vigil instrument data, and support objectives of the Vigil mission with the provision of low latency data for operational space weather applications. The AO makes a series of changes including costing of contributed labor and services, points of contact for further information, increased page limit for proposal sections, references to NASA Procedural Requirement (NPR) 7123.1B changed to 7123.1C in Requirement B-29, reinstatement of Appendix B Section J.4 Summary of Proposed Program Cooperative Contributions, and addition of Appendix B Section J.10a Draft Mission Definition Requirements Agreement.
