CHESS mission will check out the space between stars

Deep in space between distant stars, space is not empty. Instead, there drifts vast clouds of neutral atoms and molecules, as well as charged plasma particles called the interstellar medium—that may, over millions of years, evolve into new stars and even planets. These floating interstellar reservoirs are the focus of the NASA-funded CHESS sounding rocket mission, which will check out the earliest stages of star formation.

CHESS—short for the Colorado High-resolution Echelle Stellar Spectrograph—is a sounding rocket payload that will fly on a Black Brant IX suborbital sounding rocket late in the night on June 26, 2017. CHESS measures light filtering through the interstellar medium to study the atoms and molecules within, which provides crucial information for understanding the lifecycle of stars.
