Description

An unprecedented opportunity exists to advance heliospheric and geospace science, as well as improve space weather operations, by coordinating measurements across a constellation of current and near-term missions from NASA, NOAA, and ISRO orbiting the Lagrange 1 point. Though these missions were initially designed for diverse objectives and launched at different times, they now offer the potential to act as a powerful, distributed observatory providing unique 1-AU heliospheric measurements with diverse applications. To fully realize these benefits, close coordination is paramount, particularly during intervals of closest approach between two or more missions. These close-approach intervals, which replace rare conjunctions, are key for maximizing data collection opportunities and cross-calibration of measurements. While data processing and the development of advanced analysis techniques are important follow-up activities, considering those activities will help informs decisions regarding the length of close-approach intervals and necessary measurement resolution. This paper addresses a planned coordinated data collection concept, four prioritized high-level science objectives, and an implementation approach considering operational and scientific constraints.
