Why in news?

Recently, NASA launched the IMAP to study the heliosphere of the sun.

Launched by – NASA
Launch Site – NASA’s Kennedy Space Center
Goal – To map the heliosphere’s boundary, trace energetic particles, and improve space weather forecasting.
Objective – Explore and map the very boundaries of our heliosphere and study how the heliosphere interacts with the local galactic neighborhood beyond.
Launch Vehicle – Falcon 9
Location of the spacecraft – Lagrange point (L1), at around one million miles from Earth toward the Sun.
Equipped with – 10 scientific instruments, each designed to detect different types of particles or phenomena in space.

Significance –
- Uncover fundamental physics at scales both tiny and immense.
- Improve forecasting of solar wind disturbances and particle radiation hazards from space.
- Draw a picture of our nearby galactic neighborhood.
- Help determine some of the basic cosmic building materials of the universe.
- Increase understanding of how the heliosphere shields life in the solar system from cosmic rays.

Quick Facts

Heliosphere	A vast magnetic bubble created by the Sun's solar wind, which contains and protects our solar system from galactic radiation.
Solar Wind	The outward flow of energetic particles from the Sun.
Lagrange Point 1 (L1)	A stable location between the Sun and Earth where the gravitational forces of both bodies and the centripetal force for a smaller object balance out. Situated about 1.5 million kilometers from Earth towards the Sun L1 provides an unobstructed, continuous view of the Sun, making it an ideal position for solar observation missions
Interstellar Medium (ISM)	The matter that fills the space between stars and within the galaxy, which the solar wind encounters to form the heliosphere.
