Are Slope Streaks Indicative of Global-Scale Aqueous Processes on Contemporary Mars?

Zorzano, María-Paz; Bhardwaj, Anshuman; Sam, Lydia +1 more

Slope streaks are prevalent and intriguing dark albedo surface features on contemporary Mars. Slope streaks are readily observed in the equatorial and subequatorial dusty regolith regions with low thermal inertia. They gradually fade over decadal timescales. The proposed mechanisms for their formation vary widely based on several physicochemical a…

The Martian Atmospheric Boundary Layer

Spiga, A.; Vázquez, L.; Määttänen, A. +10 more

The planetary boundary layer (PBL) represents the part of the atmosphere that is strongly influenced by the presence of the underlying surface and mediates the key interactions between the atmosphere and the surface. On Mars, this represents the lowest 10 km of the atmosphere during the daytime. This portion of the atmosphere is extremely importan…

Mars ionosphere: A review of experimental results and modeling studies

Kallio, E.; Haider, S. A.; Mahajan, K. K.

In this paper we review results from atmospheric and ionospheric experiments on the early planetary missions like the Mariners, Mars, and Viking 1 and 2 Orbiters/Landers. We then discuss the new results obtained from the two latest missions, namely, the Mars Global Surveyor (MGS) and Mars Express (MEX). The MGS had three ionospheric and atmospheri…
