The secrets of the solar wind will soon come under renewed scrutiny thanks to the launch of an upcoming NASA mission that will gaze at the sun and the inner solar system.
The mission, called PUNCH, which stands for the Polarimeter to Unify the Corona and Heliosphere, is a constellation of four suitcase-sized satellites that are set to blast off for a sun-synchronous low polar orbit on Sunday (March 2). Skirting the day/night terminator, these satellites will have overlapping views of the sky from overhead to the horizon, meaning they'll be able to watch as the solar wind streams towards us.
