NASA's PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission aims to unravel the mysteries of how the Sun's corona transforms into the solar wind, a stream of charged particles that permeates our solar system. The mission is unique in its focus on bridging the gap between solar physics and solar wind physics, studying the transition of the Sun's outer atmosphere into the heliosphere – the vast region surrounding our solar system formed by the solar wind.
PUNCH will provide continuous observation of the Sun's corona and its influence on space weather, offering valuable insights into the complex processes that drive this fundamental aspect of our solar system.
