{{p}}{{span style="font-family: arial, helvetica, sans-serif;"}}{{span style="font-family: arial, helvetica, sans-serif;"}}{{span style="font-size: 17.3333px;"}}One of the objectives of the space agencies with the challenge is to find ways for astronauts to consume fresh food during longer journeys, both for food autonomy and for the health of the travelers. Participants in the challenge were provided with some studies indicating physiological and psychological damage in people who consume only ultra-processed foods over a long period.{{/span}}{{/span}}{{/span}}{{/p}}

{{p}}{{span style="font-family: arial, helvetica, sans-serif;"}}{{span style="font-size: 13pt;"}}In this way, growing vegetables in space would provide a healthier diet for the astronauts, minimizing mental health problems, as well as serving as a therapeutic activity, forming part of their routine by being adapted to the adverse conditions they face. During the project we even had to calculate the time that caring for each plant would take on a daily basis so that it would fit into the astronauts' daily lives,” professor Paulo Hercílio Viegas Rodrigues, from the {{/span}}{{a style="font-size: 14px;" href="http://www.lpv.esalq.usp.br/lab/laborat%C3%B3rio-de-cultura-de-tecidos-de-plantas-ornamentais"}}{{span style="font-size: 13pt; color: #333333;"}}Ornamental Plant Tissue Cultivation Laboratory{{/span}}{{/a}}{{span style="font-size: 13pt;"}} (LCTPO), told {{strong}}Jornal da USP{{/strong}}.{{/span}}{{/span}}{{/p}}

As a result, two different vegetable crops were presented in the proposal: strawberries and taioba.{{/span}}{{/span}}{{br style="font-family: arial, helvetica, sans-serif; font-size: 17.3333px;" /}}{{span style="color: #444444; font-family: arial, helvetica, sans-serif;"}}{{span style="font-size: 17.3333px;"}}Rodrigues says that the strawberry had been one of the last plants they had grown in the absence of natural light when they found out about the challenge. Previous studies carried out by Rodrigues with terpenes during the cultivation of tomatoes found that the concentration of carotenoids was higher than usual in the fruit. Terpenes, also known as essential oils, are substances naturally produced by some plants and which can act as natural pesticides.{{/span}}{{/span}}{{br style="font-family: arial, helvetica, sans-serif; font-size: 17.3333px;" /}}{{span style="color: #444444; font-family: arial, helvetica, sans-serif;"}}{{span style="font-size: 17.3333px;"}}The significant increase that the fruit showed in terms of nutrients is something new and was included in the award-winning project. According to the researcher, “this was probably the difference that took our project to the second stage, because the vertical garden model was also used by other participants, but improving the nutritional quality of vegetables in a natural way was an important discovery,” he says.{{/span}}{{/span}}{{br style="font-family: arial, helvetica, sans-serif; font-size: 17.3333px;" /}}{{span style="color: #444444; font-family: arial, helvetica, sans-serif;"}}{{span style="font-size: 17.3333px;"}}Rodrigues also believes that these agricultural improvements could contribute to a new line of research within the university that would be reflected for the population in the form of food with higher nutritional values.{{/span}}{{/span}}{{/p}}

Food production needs to cover around six months inside the spacecraft during the outward journey, the time spent on Mars, around 18 months, and the return journey, which would take the same amount of time as the outward journey. For this reason, there are different conditions to take into account when choosing what to plant..{{/span}}{{/p}}

It's protein-rich and rich in iron, B vitamins, as well as having a large leaf surface that doesn't need as much light intensity to develop, which would be very beneficial for astronauts.”{{/span}}{{/p}}

As such, the Esalq project focused on guaranteeing quality nutrients through plants that are easy to maintain for these astronauts.{{/span}}{{/p}}

Five finalists will then be selected for Phase 3, which has not yet been announced. Phase 3 won't take place until 2023. Therefore, USP will have an active international technical and scientific project with Nasa and the CSA for at least 12 months,” says Rodrigues. Competitors in the International category do not receive cash prizes, but technical and scientific recognition, as well as access to partnerships in this area of knowledge.{{/span}}{{/p}}

With the announcement that they had qualified for the next phase, they have already started looking for funding for the project, which involves assembling a prototype of what was presented in the first phase. “The project is theoretical, so there is nothing physically working. That's why we're worried about resources, since we're going to represent Brazil in this challenge and we don't have the funds to assemble the prototype,” he says.{{/span}}{{/p}}
