Princeton’s McComas will lead IMAP, a NASA mission to study the heliosphere

(Princeton University) Princeton astrophysicist David McComas will be the principal investigator for a $492 million science mission to sample, analyze and map particles from the sun and from the edges of interstellar space. He is presenting the mission's goals and status at the international Committee on Space Research (COSPAR) meeting today in Pasadena, California. Slated to launch in 2024, the Interstellar Mapping and Acceleration Probe mission will investigate the heliosphere, which surrounds and protects our solar system.
