Geologic constraints on early Mars climate
ES Kite - Space Science Reviews, 2019 - Springer
Early Mars climate research has well-defined goals (MEPAG 2018). Achieving these goals
requires geologists and climate modelers to coordinate. Coordination is easier if results are …

Geological evidence for multiple climate transitions on Early Mars
Landforms and deposits observed on the Martian surface suggest that Mars' early climate
supported rivers and lakes over a time span of more than a billion years. But, like Earth …

In‐situ measurements of ion density in the Martian ionosphere: Underlying structure and variability observed by the MAVEN‐STATIC instrument
Measurement of the dense cold thermal plasma in planetary ionospheres via orbiting
spacecraft is challenging because ion energies are small (0–4 eV), densities can vary by …

Do intrinsic magnetic fields protect planetary atmospheres from stellar winds? lessons from ion measurements at Mars, Venus, and Earth
The accumulation of detailed ion flux measurements from long-lived spacecraft orbiting the
solar system's terrestrial planets have enabled recent studies to estimate the rate of solar …

Martian global current systems and related solar wind energy transfer: hybrid simulation under nominal conditions
The magnetized solar wind drives a current system around Mars that maintains its induced
magnetosphere. The solar wind also transfers its energy to the atmospheric ions, causing …

Synergies between Venus & exoplanetary observations: Venus and its extrasolar siblings
Here we examine how our knowledge of present day Venus can inform terrestrial
exoplanetary science and how exoplanetary science can inform our study of Venus. In a …

Mars‐ward ion flows in the martian magnetotail: Mars express observations
We investigate Mars‐ward planetary ions (O+ and O2+) in the Martian magnetotail that
potentially reduce the amount of esca** ions. The global properties of Mars‐ward flows in …

Did Mars Possess a Dense Atmosphere During the First Million Years?
It is not yet entirely clear whether Mars began as a warm and wet planet that evolved
towards the present-day cold and dry body or if it always was cold and dry with just some …

Olivine alteration and the loss of Mars' early atmospheric carbon
The early Martian atmosphere had 0.25 to 4 bar of CO2 but thinned rapidly around 3.5
billion years ago. The fate of that carbon remains poorly constrained. The hydrothermal …

The Venusian atmospheric oxygen ion escape: Extrapolation to the early solar system
The present atmosphere of Venus contains almost no water, but recent measurements
indicate that in its early history, Venus had an Earth‐like ocean. Understanding how the …
