Geotechnical Review of Existing Mars Soil Simulants for Surface Mobility

The purpose of this paper is to provide a thorough review of the currently available Mars soil simulants and to determine those with geotechnical properties most appropriate for vehicle mobility studies. Sourcing and processing are considered since full-scale studies require bulk quantities of material on the order of tens of tons. This review identifies the top three simulants with the highest fidelity to Mars wind drift soils. These areM90, ES-2, and ES-1. In addition, recommendations to guide the development of future Mars simulants are made.

Science Café April 2021: Fetching Samples from Mars

Perseverance rover recently landed in an ancient lakebed on Mars. Its mission is to collect rock and soil samples, and place these in strategic locations for a future mission to return them to Earth. This talk provides an overview of the combined effort between NASA and the European Space Agency to bring those samples home. This involves the use of a small, but highly mobile rover, nicknamed ‘Fetch’. Fetch rover will be the first Mars rover to use flexible tires known as Spring Tires. These tires were invented in the Cleveland area by NASA and Goodyear. The benefits and challenges of this technology will be discussed in the context of this Mars mission, future missions, as well as on Earth.
