Volcanic craters and cones in central Kachchh mainland, western India: Potential analogue for the Martian studies?

Chavan, Anil; Bhandari, Subhash

The role of pre-existing faults and fractures in shaping polygonal impact craters and its tectonic implications in the southern Margaritifer Terra region, Mars

Bhattacharya, Satadru; Dasgupta, Dipayan; Kundu, Abhik +2 more

The presence of polygonal-shaped craters, i.e., craters with complete or incomplete polygonal rims along with circular or elliptical outlines, on the surface of celestial bodies has been known for nearly a century. However, many investigations on their distribution and formation have not been carried out, until recently. Scientists have proposed t…

Simulation of photoelectron flux, electron density, emission rate and limb intensity of CO(a³π) Cameron bands in the Martian thermosphere: Comparisons with (1) SPICAM and IUVS observations and (2) other model calculations

Haider, S. A.; Thirupathaiah, P.; Masoom, J.

Using analytical yield spectrum approach based on Monte Carlo method, the current study calculated the photoelectron flux, electron density, emission rate and limb intensity of carbon monoxide (CO)(a³π) bands between altitudes 90 and 200 km. The observation conditions that prevailed when the spectroscopy for investigation of the charact…

Landform evolution of Tharsis Montes and Olympus Mons of Mars: Insights from morphometric, hypsometric and chronologic evidences

Ahmad, Adnan; Nair, Archana M.

We studied the growth and evolutionary history of four major volcanoes of the Tharsis Province based on morphometry, age and hypsometric studies. Shield volcanoes of Tharsis volcanic province demonstrate marginally dissimilar landform evolutionary trends. Arsia Mons is distinct with a single caldera of large diameter and showed the highest asymmet…

Retrieval of Martian ozone and dust from SPICAM spectrometer for MY27-MY28

Montmessin, Franck; Modak, Ashimananda; Sheel, Varun

Ozone (O₃) is important in the stabilisation of CO_{{2}} in the Martian atmosphere and thus it is important to study the spatio-temporal variability of O_{{3}}. We retrieve two years of total columnar O_{{3}} from raw spectral data provided by the SPectroscopy for the Investigation of the Characteristics of the Atmosphere of Mars (SPICA…
