Journal ArticleDOI

Loss of the Martian atmosphere to space: Present-day loss rates determined from MAVEN observations and integrated loss through time

Bruce M. Jakosky, +131 more
- 15 Nov 2018 - 
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).
Journal ArticleDOI

MAVEN observations of the response of Mars to an interplanetary coronal mass ejection

Bruce M. Jakosky, +93 more
- 06 Nov 2015 - 
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.
Journal ArticleDOI

Mars’ atmospheric history derived from upper-atmosphere measurements of 38Ar/36Ar

TL;DR: A large fraction of Mars’ atmospheric gas has been lost to space, contributing to the transition in climate from an early, warm, wet environment to today’s cold, dry atmosphere.
Journal ArticleDOI

Structure and composition of the neutral upper atmosphere of Mars from the MAVEN NGIMS investigation.

TL;DR: The Mars Atmosphere and Volatile EvolutioN (MAVEN) Neutral Gas and Ion Mass Spectrometer (NGIMS) provides sensitive detections of neutral gas and ambient ion composition and reveals persistent and unexpectedly large amplitude density structures.
Journal ArticleDOI

Early MAVEN Deep Dip campaign reveals thermosphere and ionosphere variability

S. W. Bougher, +93 more
- 06 Nov 2015 - 
TL;DR: In situ measurements of the upper atmosphere reveal previously unmeasured populations of neutral and charged particles, the homopause altitude at approximately 130 kilometers, and an unexpected level of variability both on an orbit-to-orbit basis and within individual orbits.
