Summary:
- NASA has delayed the launch of two heliophysics missions, the Interstellar Mapping and Acceleration Probe (IMAP) and the Polarimeter to Unify the Corona and Heliosphere (PUNCH), from 2024 to 2025.
- The delays are due to supply chain issues and the need for additional time to complete spacecraft integration and testing.
- IMAP will study the interaction between the solar wind and the interstellar medium, while PUNCH will provide a comprehensive view of the corona and how it connects to the heliosphere.
