Mission Name: NASA’s Interstellar Mapping and Acceleration Probe (IMAP)
Launch Date: September 2025
Objective: Study the heliosphere, the bubble created by solar wind that protects the solar system from harmful cosmic radiation
Purpose:
- Understand how charged particles travel and accelerate in space
- Improve space weather prediction and protection for satellites and astronauts
Instruments: 10 advanced instruments, including:
- Energetic neutral-atom detectors
- Sensors for charged particles
- Magnetic field sensors
- Interstellar dust detectors
Location: Operates from Sun-Earth Lagrange Point 1 (L1), ~1.6 million km from Earth
Significance: Enables continuous observation of solar wind and energetic particles, helping scientists better understand the boundaries of the heliosphere and space weather effects
