The Visual Monitoring Camera (VMC) on Mars Express: A new science instrument made from an old webcam orbiting Mars
Hernández-Bernal, Jorge; Cardesín-Moinelo, Alejandro; Hueso, Ricardo +17 more
The Visual Monitoring Camera (VMC) is a small imaging instrument onboard Mars Express with a field of view of ∼40°x30°. The camera was initially intended to provide visual confirmation of the separation of the Beagle 2 lander and has similar technical specifications to a typical webcam of the 2000s. In 2007, a few years after the end of its origin…
Structural study of graben within the Margaritifer Terra region of Mars
Dasgupta, Dipayan; Kundu, Abhik; Basu, Supratik +1 more
The surface of Mars preserves a variety of structural and geomorphic features such as wrinkle ridges, graben, lobate scarps, impact basins, paleochannels etc., which owe their origin to endogenic processes of deformation as well as meteorite impacts. Graben, which form in extensional stress regimes, are one of the most common structural features i…
Seasonal variation in atmospheric optical depth (AOD) and thermal inertia (TI) inter-relationship over Martian Gale crater
Shaheen, Farzana; Krishna, A. P.; Nee Lala, Mili Ghosh +1 more
Investigating the relationship between thermal inertia (TI) and aerosol optical depth (AOD) is significant in giving insights into the seasonality of dust deposition and lifting phenomenon. The present study focuses on establishing a relationship of AOD with TI and different particle sizes over different Martian seasons. Two different Martian land…
Possible influence of Martian surface mineralogy on the detectability of atmospheric trace gases - mid-infrared simulation results
Błęcka, Maria I.
The paper focuses on the influence of the optical properties of Martian surface minerals on remotely detected gaseous components of the Martian atmosphere, when the spectrometer receives a combined signal from the Martian soil and atmosphere. Our considerations are primarily concerned with the detectability of methane, but the problem may also app…
Using synthetic disk-integrated reflectance spectra to constrain direct imaging sensitivity requirements for a Mars-like exoplanet
Wolfe, C. A.; Robinson, T. D.
The 2020 Decadal Survey on Astronomy and Astrophysics 11https://doi.org/10.17226/26141. recommended the prioritization of a space-based telescope capable of directly characterizing Earth-like exoplanets in reflected light. The planned suite of instruments onboard such a mission are expected to provide disk-integrated spectra with modera…
