We review the origin and evolution of the atmospheres of Earth, Venus and Mars from the
time when their accreting bodies were released from the protoplanetary disk a few million …

To assess Mars' potential for both harboring life and providing useable resources for future
human exploration, it is of paramount importance to comprehend the water situation on the …

Mars has undergone three main climatic stages throughout its geological history, beginning
with a water-rich epoch, followed by a cold and semi-arid era, and transitioning into present …

Water on Mars has been explained by invoking controversial and mutually exclusive
solutions based on warming the atmosphere with greenhouse gases (the “warm and wet” …

We have mapped 18,000+ circular mounds in a portion of southern Acidalia Planitia using
their sizes, shapes, and responses in Nighttime IR. We estimate that 40,000+ of these …

Morphological evidence for ancient channelized flows (fluvial and fluvial-like landforms)
exists on the surfaces of all of the inner planets and on some of the satellites of the Solar …

Earth's biological and environmental evolution are intertwined and inseparable. This
coevolution has become a fundamental concept in astrobiology and is key to the search for …

Martian surface morphology implies that Mars was once warm enough to maintain persistent
liquid water on its surface. While the high D/H ratios (∼ 6 times the Earth's ocean water) of …

The volume of Martian valley network (VN) cavity and the amount of water needed to create
the cavity by erosion are of significant importance for understanding the early Martian …

The outflow channels of Mars are widely believed to have formed through aqueous
outbursts from aquifers, implying the past existence of large near-surface water reservoirs …
