Understanding the life cycle of coronal mass ejections (CMEs)—from their initiation at the Sun to their propagation through the heliosphere and geoeffective impacts at Earth—is crucial for improving space weather forecasting. Equally important is the role of the ambient solar wind, which governs CME propagation, evolution, and interaction processes throughout the heliosphere. Observations from missions such as PSP, Solar Orbiter, STEREO, SOHO, Aditya-L1, PUNCH, and the upcoming Vigil mission, along with ground-based radio facilities, enable increasingly robust three-dimensional reconstructions of CME structure and dynamics. Advances in magnetohydrodynamic (MHD) simulations, solar wind modeling, and AI/ML techniques are further transforming predictive capabilities. This session invites contributions that comprehensively investigate CME initiation, evolution, and solar wind processes using a synergistic approach that combines multi-wavelength and multi-vantage point observations, numerical modeling, and AI/ML-based methodologies. We also encourage studies linking these processes to space weather effects across other planetary environments in the inner heliosphere.
