NOAA has a research priority to observe solar wind parameters at sub-L1 points along the Sun-Earth line. We present a proposed mission based on the Solar Cruiser architecture that can meet the first step of these research observations using solar sail propulsion technology. The mission will also fly a science payload to observe the solar wind particles and the magnetic field at sub-L1.
