The atmosphere of Mars as observed by InSight [PDF]

Nature Geoscience, 2020
The atmosphere of Mars is thin, although rich in dust aerosols, and covers a dry surface. As such, Mars provides an opportunity to expand our knowledge of atmospheres beyond that attainable from the atmosphere of the Earth. The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander is measuring Mars’s atmosphere ...

A three-dimensional atmospheric dispersion model for Mars

Progress in Earth and Planetary Science, 2021
Atmospheric local-to-regional dispersion models are widely used on Earth to predict and study the effects of chemical species emitted into the atmosphere and to contextualize sparse data acquired at particular locations and/or times. However, to date, no

Study on Effect of Aerodynamic Configuration on Aerodynamic Performance of Mars Ascent Vehicles

Space: Science & Technology, 2022
The Mars surface take-off and ascent technology is one of the key technologies for realizing the Mars sample return mission. Different from that on the moon, the gravity acceleration on the surface of Mars is 3.71 m/s2, so that the gravity loss is larger
