1. The duration of a manned mission to Mars would vary between 640 and 910 days, depending on the scenario, far longer than the 12 days it takes for a mission to the Moon. The return journey is estimated at 6 months to 2 years for a Mars mission, while it is just 3 days for a trip to the Moon.

2. [1] “[...] [for such a mission] a team of six astronauts would require 30 tonnes of supplies (water, oxygen and food), without counting the amount of water needed for the astronauts’ hygiene (showers), washing dishes (dishwasher) and clothes (washing machine), nor the weight of packaging or the means of refrigeration. To date, the most powerful launcher has only been able to deliver 9 tonnes of useful cargo to the surface of the Moon.” Christophe Lasseur, Un potager sur Mars! in: Nutrition. Servir l’espace et la Santé.

3. Mars has no real soil to speak of. The planet is covered in regolith, a layer of fine dust created by the impact of meteorites and by the effects of erosion.

7. Hydroponics is a production technique that does not use soil. Plant roots grow in an inert substrate, irrigated by a nutritional solution.
8. The second phase of the MELiSSA project in Sion, entitled
MELiSSA Food Characterisation Phase 2 - Food Processing Pre-engineering, was coordinated by Serge Pieters, dietician and lecturer at the Institut Paul Lambin in Brussels. He also coordinated the first phase of the project, but without the participation of the Institute of Life Technologies.
9. For similar reasons, all preparations based on fermentation processes are excluded.
10. Okara is a very common foodstuff in Asian countries, especially in Japan.
11. During spacewalks, the estimated requirement is 7000 Kcal/day (Nutrition. Servir l’espace et la Santé

12.“During short-term stays, they [the astronauts] only eat 60% of their rations.” Boredom with the meals is one of the reasons. (Nutrition. Servir l’espace et la Santé,
