AB: Forecasting of space weather conditions for the Space Exploration initiative will not rely on L1 monitoring alone. Spacecraft on the way to Mars will be required to depart from the Sun-Earth line. We show that in situ forecasting at the spacecraft is an option for Mars-bound space travel. Our approach of instrument requirement specification, hardware development, and data analysis tackles two possible solutions for this problem: PreSTIM, the Pre-Shock Suprathermal Ion Monitor, provides the observations necessary for interplanetary shock forecasting with low-energy foreshock ions. RAD, the Radiation Assessment Detector, is a light-weight energetic particle instrument that can be used for early radiation warnings by analyzing the onsets of solar energetic particle events. RAD continuously monitors the intensity of the radiation environment, in particular the most hazardous energetic particle species.
