Neil Armstrong may have taken the first small step for the moon, but it was John Glenn, the first apple of apple sauce for mankind.
Until we gathered in the world in 1962, scientists at NASA were not sure if humans could swallow food while they were eating. Fortunately, in zero gravity it chewed down with no hardship. Today's astronauts sometimes spend months in a month living on the International Space Station, so they're getting hungry without a few snacks!
Of course, while the human body is happy for a meal while wandering 250 miles of the Earth, the cooking and eating process is not exactly the same as returning home. That's why NASA scientists are working for the perfect astronaut menus. For people traveling in space, a healthy diet is more important for space travelers, as the body begins to lose bone and muscle mass by spending time in space. NASA has to send food to the rocket, keep it as long as possible and ensure that it provides an excellent nutritional balance – and astronauts should not be bored!
Edin Imagine eating the same food at each meal for six months. You can get bored with food and eat less than you need to lose weight, health and performance. That's why we have prepared a wide range of healthy foods for the astronauts to choose. D It's the food system manager F. Ryan Dowdy from NASA's Johnson Space Center in Houston, Texas.
There are about 200 meals that the astronauts can take. According to Dowdy, many options are surprisingly similar to the dishes we eat in the World.
Or It's important for astronauts when you're reminded of cooking at home, whether it's pasta or cheese or a chocolate pudding cake, “he says. ”Food can be an important psychological comfort in the stressful environment of the area.“
This is a unique preparation: food usually goes into space for six months before going into the tank – and once it's there it takes weeks or months – so NASA designs everything with a shelf life of at least two years. . Pasta and cheese are freeze-dried (removing most of the moisture, allows storage at room temperature) and astronauts are added to the space station hot water. The chocolate pudding cakes are preserved in a similar way to canned food, but the NASA puts it in a flexible bag, taking up less space.
Some Earth foods provide the perfect fit for zero gravity consumption. For example, they have a bread that is very good for bread, which is a very good alternative to bread – they last a long time in storage and do not form crumbs that float around and attach to the important places of the ship. Astronauts can demand small amounts of fresh fruit and vegetables according to when NASA supplies the product, but they often consume a variety of super-durable stored foods.
With NASA looking at the future of the spaceship – Mars – and perhaps even further – missions must design more stable foods. It takes about eight months to get to Mars, and the astronauts will have to bring food for the trip home. Dowdy says NASA is working to extend the shelf life of food for about five years, but experiments in space farming are part of the plan.
The astronauts in the ISS can plant plants such as lettuce in small quantities, but Dowdy says it will take some time for it to be a sustainable source of calories.
He thinks that 3D printed treats can be on the menu one day. One thing is certain: he will have a lot of scientific knowledge to feed the future space researchers.
