IMAP probe seeks out the edge of the solar system

IMAP probe seeks out the edge of the solar system

IMAP rotates four times a minute. From its orbit about 1.5 million kilometers from Earth, it can absorb atoms from all directions.

IMAP should provide the most comprehensive data yet over the entire heliosphere. For example, IMAP-Hi alone is expected to capture 25 times more particles than the equivalent sensor on its predecessor, IBEX.

This gives us new insights into the shape of the solar atmosphere and its changes over time.

Only through IMAP’s precise measurements can astrophysicists determine the shape of the heliosphere and gain a detailed view of the boundary between the solar system and interstellar space.

They hope to create a detailed 3D model of the heliosphere. This could be useful, for example, when astronauts travel long distances. The deflection of cosmic rays by the heliosphere is crucial for space travelers to be able to make long journeys without serious damage to their bodies.

For example, it is important to know any weak points in the heliosphere shield so that the path and timing can be adjusted accordingly when astronauts travel to Mars.

The next step is to better understand how cosmic rays affect the outer edge of the heliosphere.
