Extended Data Fig. 1: Geometry of MAVEN apoapsis location throughout the MAVEN mission.
From: Martian water loss to space enhanced by regional dust storms

MAVEN orbit numbers and Earth Year/Month dates are shown on the bottom axis, with Mars Year and Ls on the top axis. The blue/brown and green curves show the location of MAVEN’s apoapsis in solar zenith angle (SZA) and local time, and in geographic latitude, respectively. The tan curve shows the latitude of the subsolar point. Intermittent spacecraft activities such as MAVEN Deep Dips (DD-X), Earth-Sun-Mars conjunctions, and the recent aerobraking campaigns are also indicated. IUVS Stellar occultation campaigns are indicated with the star icons. Time periods useful for IUVS H loss measurements occur when apoapsis SZA and latitude are both close to zero and occur relatively rarely in the dataset. Unfortunately these time periods are relatively rare in the dataset.
