The MinXSS-2 Mission – Overview

September 9

The MinXSS-2 mission, scheduled to launch in 2018 November, improves several aspects of MinXSS-1. The primary science instrument, an Amptek X123 silicon drift detector, has been upgraded with higher energy resolution and greater dynamic range. That means we’ll be able to resolve spectral lines better and we’ll be able to observe larger solar flares without […]
