I. Introduction
On February 18, 2021, the Mars 2020 Perseverance rover successfully entered the Martian atmosphere and landed safely on the surface. During entry, the Mars 2020 aeroshell was outfitted with a sensor suite, known as Mars Entry, Descent, and Landing Instrumentation 2 (MEDLI2), which measured pressures, in-depth temperatures, and surface heat fluxes at various points on the...
An overview of the Dragonfly aerothermal environments and simulations performed will be presented. Titan’s atmosphere predominantly consists of nitrogen (~98% by mole) with small amounts of methane (~2% by mole) and other trace gases. CN is a strong radiator and is found in nonequilibrium concentrations for Titan entry, and is of particular importance on the backshell, where radiation...
This paper presents preliminary stagnation point VUV radiation measurements taken over a 25 mm diameter, 75 mm wide semicylindrical model at 13 and 14 km/s Mars return re-entry conditions using the X2 expansion tube facility at the University of Queensland.
In February 2021, the Perseverance rover was brought to the surface of Mars by the Mars 2020 mission. A feature of the Mars 2020 capsule was instrumentation to measure its entry, descent and landing (EDL) with the so-called Mars EDL Instrumentation 2 (MEDLI2) [1]. The MEDLI2 introduced, among other things, backshell instrumentation, including a broadband radiometer. The radiometer was mounted...
