Abstract: In this paper, we assess the feasibility of the neoPASCAL thermal design by performing thermal analysis. NeoPASCAL is a network of compact solar-powered landers on Mars which aim to validate Mars General Circulation Models (GCMs) by measuring the diurnal variations in surface pressure. It is a modern revision of the original Pascal mission proposed in 1996, with each science station being ten times smaller in size and mass (a kg or less) by using miniaturised commercial off-the-shelf (COTS) electronic components and satellite platforms (i.e., Boardsat and CubeSat platforms). Despite the harsh thermal environments, the analysis shows that the Boardsat-based model can survive at ≤ ±60° latitude by using a large flexible-solar-cells-attached sail that was originally designed to attain soft landing. If successful, such a network would provide an unprecedented set of global meteorological data that can be used to investigate various meteorological phenomena including the general circulation.
