Mission

IMAP (Interstellar Mapping and Acceleration Probe) is a NASA mission to study interactions between solar wind and the local interstellar medium. Carrying a suite of 10 scientific instruments, IMAP is able to investigate how particles are accelerated, determine their composition, as well as help to advance space weather forecasting models.

The IMAP launch also includes the space weather satellite SWFO-L1 (Space Weather Follow-On - L1) for NOAA and the GLIDE (Global Lyman-alpha Imagers of the Dynamic Exosphere/Carruthers Geocorona Observatory) mission to study far ultraviolet emission in the Earth's exosphere.

Launch Provider

SpaceX

Commercial · United States of America · Founded 2002 · CEO Elon Musk

Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.
