Our project intends to place several components inside a spacecraft, depending on its dimensions and load capacity. Initially using PHOTOBIOREACTORS (already under development by NASA), water tanks for fish farming and culture tables (AQUAPONIA), and tanks for algae farming. Part of these structures can stay in centrifugal systems to create a false gravity through centrifugal energy, which would allow fish to be reared and prevent the escape of microparticles of water inside the aircraft.

The Triangle project is divided into three main pillars:

- Food production and diversity;

- Capture of CO2 and production of O2;

- Maximum use of waste;

1 – Food production and diversity

Initially, the production of algae food is a priority, since algae have nutritional value, they depend on small spaces for production.

Next, the goal is to create an aquaponics system, integrating it into a closed system for raising fish, vegetables and greens.

In a third moment, create fungi and bacteria with the objective of creating alternative sources of food and probiotics.

2 – CO2 capture and O2 production

One of the challenges for long-term flights will be the production or storage of O2 and the production of CO2 resulting from the breathing of astronauts and other living organisms, since the human being produces about 1 kilo of CO2 per day by breathing.

In view of this, the production of algae for food production also contributes to solving this problem because algae have a high CO2 capture rate and there are already tests and functional equipment for aerospace travel (Photobioreactors). The way this happens is through Fotosynthesis, a process carried out by plants to produce the energy necessary for their survival. Photosynthesis also plays another important role in nature: air purification, as it removes the carbon dioxide released in our breathing and, in the end, releases oxygen into the atmosphere.

Carbon sequestration is so important that with the removal of CO2 from the atmosphere plus the photosynthesis process, it contributes to the maintenance of living beings, as photosynthesis releases O2 into the spacecraft's closed atmosphere.

3 - Maximum use of waste

Another objective is to create a closed system where the generation of waste is canceled due to use in the system itself. This already occurs with the urine and sweat of astronauts, through equipment that produces water and nitrites and nitrate salts for planting. There is also an opportunity to use the gases emitted by plants (in addition to O2) to create a planting system that promotes synergy between cultivars.

AQUAPONIA

Aquaponics – defined as the integration of aquaculture with hydroponics – is increasingly consolidated worldwide as an activity of great importance for agribusiness. This has meant that this practice is no longer indicated only for small-scale production. As the system is based on water recycling (RAS - Recirculation Aquaculture System), it minimizes the generation of nutrient-rich effluents and thus avoids the eutrophication of the receiving water bodies. Keeping the system closed regarding the production and emission of pollutants.

The system involves raising fish in a tank that feeds a vegetable production table. The fish create a residue (ammonia) which, through biofiltration - a natural two-stage process with the intervention of two species of nitrifying bacteria, transforms ammonia into nitrite and nitrite into nitrate. After passing through the filter tank, the water with nitrate passes to the planting tables, where vegetables absorb the nitrate creating a self-sustaining closed system. Fish, on the other hand, will feed on lemna, a genus of free-floating aquatic flowering plants belonging to the subfamily Lemnoideae (ex-family Lemnaceae) of the family Araceae. Some of the species of this genus are used because they are fast growing (under favorable conditions the number of specimens can double in 48 hours) and easy to cultivate in a controlled and soilless environment, they are used as a model organism for community ecology studies, studies of basic plant biology, ecotoxicology and biopharmaceutical production. They are also used as a food source for animals in livestock and aquaculture and as a constituent of sewage treatment facilities.

The aquaponics system must be in a space on the spacecraft where there can be a constant rotation movement allowing the existence of a centrifugal force to ensure that the elements produced remain within a watertight area (tanks, production tables, etc.).

Our pitch:

"We accepted the challenge to create better conditions for the Mars trip. Among the great problems faced by astronauts is the lack of food options, the quality and the freshness of food, the production of oxygen and carbon dioxide, the generation of energy and the waste from this trip.

Our project aims to ensure a safe and quality mission to Mars.

For real, we thought about supplying the ship with water that will be used in different ways.

First, through electrolysis, this water will produce a supply of oxygen, essential for life, and hydrogen that will be used as fuel.

This water will also be used to produce algae in a PHOTOBIOREACTOR in order to absorb the CO2 produced by the crew and, through photosynthesis, produce oxygen.

Likewise, this algae can also be consumed. In parallel to this, also, we will use an AQUAPONIA system, which is the integrated farming of fish and vegetables, ensuring the production of quality food in a continuous and self-sustainable system."

our first pitch

"This project aims to solve the food issue and the production of CO2 and consumption of O2.

Initially, we planned to build an integrated system using water, integrated agricultural production and fish farming.

In the model we are developing, the suggestion is to create fish that have a high reproduction rate as well as vegetables with high nutritional value and that complement the astronauts' diet.

This system would guarantee the diversity of foods to be offered to astronauts, guaranteeing a more balanced and nutritious diet, as well as considerably reducing thas considerably reducing the stress caused by a very restricted diet. In parallel we suggest the creation of algae and macroalgae

it was incredible, we had the help of many mentors who were participating in the stages of Belem and São Caetano do Sul.

"I'm older and the group accepted me. it was a fantastic journey and i have to thank Takaki's mentors and team" - Eliete

We started early and have been working until now. It was a great adventure and we hope to participate in other editions.

Mentoring and support were very important.

Algas e aquaponia

Cientistas do mundo todo têm realizado pesquisas de como o homem poderia produzir seu próprio alimento na lua e também em marte... Você sabia que a aquaponia é uma das técnicas de produção fortemente considerada por eles?

“...projeto social de aproveitamento dos resíduos da dessalinização no cultivo de microalgas (spirulina) e seus derivados que foi implantado em São João do Cariri, semiárido brasileiro”

“...diversas espécies de peixes, crustáceos e algas que apresentaram nos últimos anos, significativas taxas de crescimento e potencial para serem utilizadas em unidades aquapônicas. Dentre as espécies de peixes, destacam-se a: tilápia (Oreochromis niloticus), carpa (Cyprinus carpio), truta (Salmo trutta fario) e catfish (Ictalurus punctatus); espécie nativa como o tambaqui (Colossoma macropomum), além de peixes ornamentais... Em relação as algas, a mais estudada até o momento na aquaponia é a microalga Spirulina (Arthrospira platensis) utilizada para fabricação de fármacos. O pH é uma variável crítica, para os organismos aquáticos, sendo que o pH ótimo fica entre a faixa de 6,5 e 9,0.”

“A aquaponia tem sido predominantemente difundida por todo o mundo e envolve a integração entre a aquicultura e a hidroponia em sistemas de recirculação de água e nutrientes. Além disso, apresenta-se como alternativa real para a produção de alimentos de maneira menos impactante ao meio ambiente, por suas características de sustentabilidade. Assim, está entre as técnicas sustentáveis dentro do sistema de produção de organismos aquáticos em cativeiro integrado com a hidroponia, capaz de garantir benefícios para ambos ao permitir que as plantas utilizem os nutrientes provenientes da água do cultivo de peixes, melhorando a qualidade da água.”

Spirulina e Chlorella em aquaponia de água doce

“Há uma enorme variedade de microalgas na Terra, mas a chlorella e a biomassa de cianobactérias conhecida como spirulina são as duas mais comumente produzidas e usadas como suplementos alimentares”

“Comprimidos e farinhas de spirulina e chlorella passaram a ser comercializados e anunciados como ricos em vitaminas e minerais, ferro e proteínas.”

“O alto teor de proteínas faz das microalgas uma alternativa à carne.”

“Por enquanto, elas tendem a ser adicionadas aos alimentos em pequenas medidas, mais como um complemento.”

Desvantagem da spirulina – cheiro e sabor

"A spirulina é composta essencialmente entre 55 e 70% de proteína e possui um melhor perfil de aminoácidos do que outros alimentos de origem vegetal", diz a nutricionista Rhiannon Lambert, "mas isso não significa que seja melhor que a proteína de origem animal."

“As microalgas contêm Omega 3, mas é menos biodisponível e acessível para nós do que o Omega 3 que encontramos nos peixes. O mesmo vale para a vitamina B12, que não é biodisponível no corpo”

"Microalgas e spirulina podem ser cultivadas em todos os tipos de local. Na água, nos oceanos, em lagoas, em lagos e assim por diante. Até mesmo no seu quintal e na neve", diz Alison Smith.

As microalgas podem até ser cultivadas no espaço — e podem ser usadas para alimentar astronautas em longas missões a Marte.
