The NASA-credited images below are from the BBC News article Europe pushes ahead with 'dune buggy' Mars rover which explains that it will drive around quickly on it's big 70 cm wheels (see article for more details) and:
The new rover is dubbed "Fetch" because its mission will be to find and retrieve the rock samples that have been collected and cached on the surface by the American Perseverance rover, which is heading to Mars next month.
The image depicts a rocket launching from a lander carrying the retrieved samples to orbit, where they will be transferred to another spacecraft that will bring them back to Earth where they hopefully won't start another pandemic.
The article goes on to explain that several large European space contractors will be involved, including Airbus.
Question: Who will build this particular rocket to be launched from the surface of Mars? What kind of rocket is this likely to be? What kind of propellant(s), how many stages, etc.
- Does NASA still plan for the Mars Ascent Vehicle to burn wax from the surface to orbit?
- Why NASA's sudden renewed (apparently) interest in Wax hybrid engines? Which property is so attractive now?
- What properties define a good solid propellant for a hybrid engine? (e.g. why not use wood?)
