I, You, We, Us

How Do You Like Your Turkey? Home-Cooked or Rocket-Launched?

It’s Thanksgiving, which means that you’re probably thinking about food right now. And here at NASA, we have to think about food very seriously when we explore space!

Astronauts Need to Eat, Too!

Like for you on Earth, nutrition plays a key role in maintaining the health and optimal performance of the astronauts. The Space Food Systems team is required to meet the nutritional needs of each crew member while adhering to the requirements of limited storage space, limited preparation options, and the difficulties of eating without gravity. 

Good food is necessary being comfortable on a mission a long way from home — especially for crewmembers who are on board for many months at a time. It’s important that the astronauts like the food they’re eating everyday, even given the preparation constraints!

Astronaut Food Has Not Always Been Appetizing

The early space programs were groundbreaking in a lot of ways — but not when it came to food. Like today, crumbs had to be prevented from scattering in microgravity and interfering with the instruments. Mercury astronauts had to endure bite-sized cubes, freeze-dried powders, and semi-liquids stuffed into aluminum tubes. The freeze-dried food were hard to rehydrate, squeezing the tubes was understandable unappetizing, and the food was generally considered to be, like spaceflight, a test of endurance.

However, over the years, packaging improved, which in turn enhanced food quality and choices. The Apollo astronauts were the first to have hot water, which made rehydrating foods easier and improved the food’s taste. And even the Space Shuttle astronauts had opportunities to design their own menus and choose foods commercially available on grocery store shelves. 

 The Wonders of Modern Space Food

Nowadays, astronauts on the International Space Station have the opportunity to sample a variety of foods and beverages prepared by the Space Food Systems team and decide which ones they prefer. They can add water to rehydratable products or eat products that are ready to eat off the shelf.

All the cooking and preparation has been done for them ahead of time because 1) they don’t have room for a kitchen to cook on the space station 2) they don’t have time to cook! The crewmembers are extremely occupied with station maintenance as well as scientific research on board, so meal times have to be streamlined as much as possible. 

Instead of going grocery shopping, bulk overwrap bags (BOBs!) are packed into cargo transfer bags for delivery to the space station. Meal based packaging allows the astronauts to have entrees, side dishes, snacks, and desserts to choose from. 

Taste in Space

The perception of taste changes in space. In microgravity, astronauts experience a fluid shift in their bodies, so the sensation is similar to eating with a headcold. The taste is muted so crewmembers prefer spicy foods or food with condiments to enhance the flavor. 

We Can’t Buy Groceries, But We Can Grow Food!

Growing plants aboard the space station provides a unique opportunity to study how plants adapt to microgravity. Plants may serve as a food source for long term missions, so it’s critical to understand how spaceflight affects plant growth. Plus, having fresh food available in space can have a positive impact on astronauts’ moods!

Since 2002, the Lada greenhouse has been used to perform almost continuous plant growth experiments on the station. We have grown a vast variety of plants, including thale cress, swiss chard, cabbage, lettuce, and mizuna. 

And in 2015, Expedition 44 members became the first American astronauts to eat plants grown in space when they munched on their harvest of Red Romaine. 

Earthlings Can Eat Space Food, Too

To give you a clear idea of how diverse the selection is for astronauts on board the space station, two earthlings gave the astronaut menu a try for a full week. Besides mentioning once that hot sauce was needed, they fared pretty well! (The shrimp cocktail was a favorite.)

Space Technology for Food on Earth

Not only has our space food improved, but so has our ability measure food production on Earth. Weather that is too dry, too wet, too hot, or too cool can strongly affect a farmer’s ability to grow crops. We collaborated with the United States Agency for International Development to create a system for crop yield prediction based on satellite data: the GEOGLAM Crop Monitor for Early Warning.

This map measures the health, or “greenness” of vegetation based on how much red or near-infrared light the leaves reflect. Healthy vegetation reflects more infrared light and less visible light than stressed vegetation. As you can see from the map, a severe drought spread across southern Mexico to Panama in June to August of this year. 

The Crop Monitor compiles different types of crop condition indicators — such as temperature, precipitation, and soil moisture — and shares them with 14 national and international partners to inform relief efforts.

Thanksgiving in Space 

Space food has certainly come a long way from semi-liquids squeezed into aluminum tubes! This year, Expedition 57 crewmembers Commander Alexander Gerst and Flight Engineer Serena M. Auñón-Chancellor are looking forward to enjoying a Thanksgiving meal that probably sounds pretty familiar to you: turkey, stuffing, candied yams, and even spicy pound cakes!

Hungry for More?

If you can’t get enough of space food, tune into this episode of “Houston, We Have a Podcast” and explore the delicious science of astronaut mealtime with Takiyah Sirmons. 

And whether you’re eating like a king or an astronaut, we wish everybody a happy and safe Thanksgiving!

Past projects? Similar concepts?

During specialism, I have explored the concept of healing by sharing my experience in hospital due to having frequent asthma attacks in the Radio project. I found the medium of sound very effective when telling my experience as there are so many sounds relating to the hospital and sickness in general. There is also the unmistakable inhaler sound that is very specific to asthma. I wish to build upon this project during FMP by interviewing my parents not only because I cannot recall most of what happened, but also gives an insight into what it was like from their perspective.

Although I had difficulty with it at first, I wish to utilise stop motion animation in my FMP because it creates the more character and materiality than digital animation. I feel like digital animation would suit the more impersonal areas, where as the materiality is needed to create more personal details.

I wish to also somehow incorporate rubber stamping as again, it’s material nature would lend itself quite well in the subject.

Best Thing Since Sliced Bread

I really enjoyed the researching aspect of this project, however I struggled with being strict and selective with what I wanted to communicate in the final outcome. My plan was to make an interactive book showing the properties of tape without being obvious... which then turned into an interactive roll.... which then ended up showing the ‘origin story’ of each type of tape. I feel as though I just wasn’t clear enough with what I wanted to communicate, which is reflected in my final outcome. I’m determined to develop on what I have already done and create a sufficient outcome which clearly communicates the properties of tape.
