Analyzing the density of impact craters on planetary surfaces is the only known technique for
learning their ages remotely. As a result, crater statistics have been widely analyzed on the …

A committee of the Mars Exploration Program Analysis Group (MEPAG) has reviewed and
updated the description of Special Regions on Mars as places where terrestrial organisms …

A new catalog of 210 open-basin lakes (lakes with outlet valleys) fed by valley networks
shows that they are widely distributed in the Noachian uplands of Mars. In order for an outlet …

Subsurface radar sounding data indicate that lobate debris aprons found in Deuteronilus
Mensae in the mid‐northern latitudes of Mars are composed predominantly of water ice. The …

We used a grid‐mapping technique to analyze the distribution of 13 water‐and ice‐related
landforms in Acidalia Planitia as part of a joint effort to study the three main basins in the …

Today, a 34 m global equivalent water layer (GEL) lies in the Martian polar‐layered deposits
and shallow ground ice. During the Amazonian, 3 m was outgassed, and 31 m was lost to …

Although ice in the Martian midlatitudes is typically covered by a layer of dust or regolith, it is
exposed in some locations by fresh impact craters or in erosional scarps. In both cases, the …

Lobate debris aprons (LDA) and lineated valley fill (LVF) have been known to characterize
the mid-latitude regions of Mars since documented by Viking; their flow-like character …

Abstract On February 18, 2021 NASA's Perseverance rover landed in Jezero crater, located
at the northwestern edge of the Isidis basin on Mars. The uppermost surface of the present …

Glacial landforms on Mars, including concentric crater fill (CCF), lineated valley fill (LVF),
and lobate debris aprons (LDA), were mapped between~±30 and 50° latitude, and …
