The MAVEN magnetic field investigation is part of a comprehensive particles and fields
subsystem that will measure the magnetic and electric fields and plasma environment of …

Recent measurements by Mars Global Surveyor and Mars Express have greatly increased
the number of observations of the martian dayside ionosphere available for study. Together …

The presence of an atmosphere over sufficiently long timescales is widely perceived as one
of the most prominent criteria associated with planetary surface habitability. We address the …

When the supersonic solar wind reaches the neighborhood of a planetary obstacle it
decelerates. The nature of this interaction can be very different, depending upon whether …

Magnetohydrodynamics (MHD)-based global space weather models have mostly been
developed and maintained at academic institutions. While the “free spirit” approach of …

Mars was once wet but is now dry, and the fate of its ancient carbon dioxide atmosphere is
one of the biggest puzzles in martian planetology. We have measured the current loss rate …

The evolution and escape of the martian atmosphere and the planet's water inventory can
be separated into an early and late evolutionary epoch. The first epoch started from the …

Abstract The Mars Atmosphere and Volatile Evolution mission has obtained comprehensive
particle and magnetic field measurements. The Solar Wind Electron Analyzer provides …

Two of the primary goals of the MAVEN mission are to determine how the rate of escape of
Martian atmospheric gas to space at the current epoch depends upon solar influences and …

This tutorial deals with the question of atmospheric escape on Mars. After a brief introduction
describing the general context of Mars escape studies, we will present in Section 2 a …
