Design of Earth-Mars transfer trajectories using evolutionary-branching technique [PDF]

open access: yes, 2005
In this paper a novel global optimisation approach is used to search for potentially interesting solutions for a mission to Mars. The approach blends the characteristics of evolutionary algorithms with the systematic search, typical of branching 11 ...

The Absence of an Ocean and the Fate of Water all Over the Martian History

open access: yesEarth and Space Science, 2020
Existing data returned in >40 years of planetary missions to Mars provided a good basis to understand that an ocean never existed on the surface of the planet during its whole history.

Identifying and Interpreting Stratification in Sedimentary Rocks on Mars: Insight from Rover and Orbital Observations and Terrestrial Field Analogs [PDF]

open access: yes, 2013
Sedimentary rocks on Mars provide insight into past aqueous and atmospheric processes, climate regimes, and potential habitability. The stratigraphic architecture of sedimentary rocks on Mars is similar to that of Earth, indicating that the processes ...
