What do astronauts eat when they're on Mars for nearly 3 years?

At the end of a labyrinth-like passage leading into the depths of the building from the 1960s is a group of scientists wearing white shirts churning, mixing, counting, and most importantly tasting the flavors of the dishes. Their mission is to menu for the journey to bring people to Mars by 2030.

The menu must be suitable for a group of 6-8 astronauts, helping them stay healthy and happy with a variety of delicious and varied dishes. This is not simple because the journey for astronauts to set foot on Mars will last 6 months. After that, the astronauts will stay there for 18 months, then take another 6 months to return to earth. The hard work of the chefs serving the astronauts is comparable to having to go shopping for the entire family for 3 years with just one go.

'Mars is very different, not only because it is far from the earth. We were unable to deliver aircraft carrying supplies every 6 months as on the International Space Station (ISS) , " said Maya Cooper, a researcher at Lockheed Martin and also a team leader for menu research. onion to Mars, said.

Experts are trying food for astronauts on Mars.

Astronauts flying to ISS can choose among 100 dishes. But all are cooked or chilled food, with a shelf life of up to 2 years. The astronauts tried and accepted the food before taking off, but the taste of the dish was greatly reduced in places where there was no gravity.

There is a bit of gravity on Mars, allowing NASA to consider some changes in the menu. Journey to Mars can allow astronauts to do some things like pick up vegetables or cook a little. Although gravity on Mars is less than on earth, scientists think they can still boil water with a pressure cooker.

American scientists are considering building 'Mars' green houses , which grow many kinds of fruit trees and vegetables - from carrots to peppers - in the water. The astronauts will take care of the garden and harvest and process, along with the materials brought from the earth, to serve daily meals.

The purpose of this plan is to help astronauts get enough nutrients and minerals to ensure their health, in order to perform well their assigned tasks.

Jerry Linerger, a retired astronaut who stayed on ISS for 132 days, said food is a very important factor for astronauts' psychology. The boredom of eating every day is the same thing that is extremely annoying.

Currently, the special kitchen area has built 100 recipe recipes, all of which are vegetarian because astronauts will not have dairy or meat products. The preservation of milk and meat for such a long time is not possible, and it is not feasible to bring a dairy cow to Mars.
