Why ISS will soon smell like freshly baked cookies

Space food has come a long way from powders,mashed potatoes and tubes up to, if not products prepared by professional chefs, then at least the usual "earthly" food. But can astronauts ever really cook homemade dishes in space? The case, of course, has not yet reached the steaks and fried potatoes, but it will be possible to prepare a delicious dessert on the International Space Station this fall already this autumn.

What is the drawback of current space food?

Considering the fact that food forAstronauts are carefully selected and only the best of them get to the “table”; space food is quite healthy and nutritious. However, in the process of cooking it is carefully preserved, which affects the taste. In fact, we have different types of canned food, and this is not at all like freshly prepared dishes. In addition, cooking on their own has an important psychological aspect.

“The very act of cooking helps. When we trained on survival expeditions on Earth, cooking added a sense of normality to what was happening. And I think that this is to some extent lacking in space, ”says former NASA astronaut Mike Massimino.


One of the chambers of the space furnace in which you can make cookies. The dough will fit into the chamber.

How does the space oven for making cookies

The device was developed by Zero G Kitchenco NanoRacks. Inside the oven on Earth, the air heats up and rises, baking dishes. It then cools and moves down where it heats up again. This causes the air to circulate continuously. But in the conditions of microgravity of the ISS, the air will not “float” to the top of the furnace.

To overcome this problem, there is a tray in the oven,which keeps the food in place, and the heating elements installed around its inside evenly distribute heat. But airflow is not the only problem. Fire poses a huge risk, so the developers equipped the furnace with special ventilation components and insulating modules in order to be tested in the NASA security department. In this case, "from scratch" to cook cookies on the ISS still will not work, because ingredients like eggs and flour for the dough will just fly throughout the station. Therefore, the “cosmic culinary specialists” will be forced to use dough blanks previously made and frozen on Earth.

Only now enjoy the astronauts can onlythe smell of freshly made biscuits. The fact is that after baking the first batch, they will have to send all the samples to Earth to study and determine whether it is dangerous to use cosmic cookies. And if all goes well, the brave astronauts will be able to eat the second batch.
