Vigil

Overview

The Vigil mission will help improve space weather services. The primary goal of the Lagrange mission is to enable improved forecasts of the arrival of space weather phenomena at Earth, through real-time monitoring of the Sun and solar wind from the unique Lagrange L5 vantage point. The Lagrange payload comprises two instrument suites, the remote-sensing instrument package that includes a solar magnetograph, an Extreme Ultraviolet Imager, a coronagraph, and a heliospheric imager, alongside an in-situ package composed of an X-ray flux monitor, a solar wind analyser, a magnetometer, a medium energy spectrometer, and a radiation monitor.

RAL Space involvement

RAL Space leads the four-spacecraft remote-sensing instrument package, as well as leading two of the instruments therein, the coronagraph and heliospheric imager.
