An artist’s illustration of NASA’s Interstellar Mapping and Acceleration Probe, a mission to research the interplay of the solar’s photo voltaic wind with the winds of different stars. It will launch in 2024.
NASA will launch a new mission in 2024 to assist scientists higher perceive the bubble that surrounds the photo voltaic system, company officers mentioned.
This enormous bubble, which often known as the heliosphere, is created by the sun; it consists of charged photo voltaic particles and photo voltaic magnetic fields. The heliosphere helps defend Earth and different photo voltaic system our bodies from area radiation, blocking some extremely energetic cosmic rays that originated in interstellar area.
But the heliosphere boundary is way from impenetrable. The new NASA mission, referred to as the Interstellar Mapping and Acceleration Probe (IMAP), will gather and research fast-moving particles that handle to make it by means of. [Solar Quiz: How Well Do You Know Our Sun?]
“This boundary is where our sun does a great deal to protect us. IMAP is critical to broadening our understanding of how this ‘cosmic filter’ works,” Dennis Andrucyk, deputy affiliate administrator for NASA’s Science Mission Directorate in Washington, said in a statement Friday (June 1). “The implications of this research could reach well beyond the consideration of Earthly impacts as we look to send humans into deep space.”
IMAP was chosen from a steady of candidate proposals submitted late final 12 months, NASA officers mentioned. The probe will launch to the Earth-sun Lagrange Point 1, a gravitationally steady spot in area about 930,000 miles (1.5 million kilometers) sunward from our planet.
IMAP will use 10 onboard science devices to characterize the particles streaking by means of that neighborhood. Such work ought to make clear the interplay between the interstellar medium and the solar wind — the stream of charged particles flowing consistently from the solar — and assist researchers higher perceive how cosmic rays are accelerated inside the heliosphere, amongst different issues, NASA officers mentioned.

The price of the mission is capped at $492 million, not together with the launch automobile. IMAP’s principal investigator is David McComas of Princeton University, and the mission will likely be managed by The Johns Hopkins University’s Applied Physics Laboratory in Laurel, Maryland.
IMAP is the fifth mission in NASA’s Solar Terrestrial Probes program. The different 4 are the Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics mission (TIMED), which launched in December 2001; Hinode, a collaboration with the Japan Aerospace Exploration Agency that lifted off in September 2006; the Solar Terrestrial Relations Observatory (STEREO), a joint mission with the European Space Agency that launched in October 2006; and the Magnetospheric Multiscale mission, which launched in March 2015.
