Summary:
- NASA's Interstellar Mapping and Acceleration Probe (IMAP) spacecraft is being prepared for launch, which is scheduled for 2025.
- IMAP will study the boundary between the solar system and interstellar space, known as the heliosphere, to better understand the interaction between the Sun's solar wind and the surrounding interstellar medium.
- The information gathered by IMAP will help scientists understand the effects of this interaction on the Earth and other planets, as well as the broader environment of our solar system.
