NASA has advanced the Chromospheric Magnetism Explorer (CMEx) mission concept to an extended period of Phase A development. This mission, led by Dr. Holly Gilbert at the National Center for Atmospheric Research (NCAR), aims to make the first continuous observations of the solar magnetic field within the Sun's chromosphere. The chromosphere, a dynamic layer above the Sun's visible surface, is crucial for understanding the genesis of solar eruptions and the solar wind, which can significantly impact Earth. The primary objective of CMEx is to bridge a critical knowledge gap by continuously tracking magnetic field changes in the chromosphere. These observations are expected to vastly improve the ability to forecast hazardous space weather events, such as coronal mass ejections and solar flares, that can disrupt radio communications, damage satellites, affect power grids, and pose risks to astronauts. While the article's headline refers to the chromosphere as the 'hidden heart' and claims 'for the first time,' this phrasing is somewhat sensationalized. The chromosphere is an atmospheric layer, not the deep core. However, the specific goal of *continuous magnetic-field observations in this region* is indeed a novel undertaking. Other missions like the Parker Solar Probe have already 'touched' the Sun's corona, and SOHO has detected g-modes in the solar core, representing other 'firsts' in solar exploration.
