TL;DR: The MAVEN spacecraft has eight science instruments (with nine sensors) that measure the energy and particle input from the Sun into the Mars upper atmosphere, the response of the upper atmosphere to that input, and the resulting escape of gas to space as mentioned in this paper.

TL;DR: SOLAR2000 captures the essence of historically measured solar irradiances and this expands knowledge about the quiet and variable Sun including its historical envelope of variability.

TL;DR: In this article, the authors used observations of the Mars upper atmosphere made from the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft to determine the loss rates of gas from the upper atmosphere to space for a complete Mars year (16 Nov 2014 − 3 Oct 2016).

TL;DR: Observations and models both show an enhancement in escape rate of ions to space during the Mars upper atmosphere, ionosphere, and interactions with the Sun and solar wind during an interplanetary coronal mass ejection impact in March 2015.

TL;DR: In this paper, the authors decomposed the solar extreme-ultraviolet (EUV) irradiance observations from the NASA Solar Dynamics Observatory (SDO) EUV Variability Experiment into four distinct characteristics during flares.
