NASA's IMAP mission, launched on September 24, 2025, aboard SpaceX's Falcon 9, will study the Sun's magnetic influence. Exploring the heliosphere, it aims to map charged particles and solar wind, crucial for understanding space weather. This mission will analyze how the Sun affects satellites, astronaut safety, and conditions for life on Earth.

NASA research reveals that the heliosphere, our solar system's protective bubble, may resemble a deflated croissant rather than a comet. This new model, based on the behavior of solar wind particles, has significant implications. It impacts understanding cosmic radiation shielding, space travel safety, and the potential for life on exoplanets by influencing astrosphere effectiveness.
