intro

On August 10, 2015, the image of three crewmembers of the International Space Station (ISS) tasting a snack of a lettuce that had been grown and harvested onboard, impacted mass media all over the world. «It was one small bite for man, one giant leap for #NASAVEGGIE and our #JourneytoMars. #YearInSpace», wrote the astronaut Scott Kelly in Twitter below the videoclip showing the salad snack

He had become the first real space farmer.
This event was an outstanding outcome of the project “Vegetable Production System” (“Veggie”), a plant growth facility that had been capable of producing a small crop of a salad-type plant to provide the crew with a safe source of fresh food of good quality in terms of taste and nutrition. In addition, the culture served as a relaxing and recreational activity for the crew.

«The farther and longer humans go away from Earth, the greater the need to be able to grow plants for food, atmosphere recycling and psychological benefits», said Gioia Massa, Veggie’s payload scientist. «I think that plant systems will become important components of any long-duration exploration scenario».
These statements expressed by Dr. Massa are shared by all parties involved in the coming enterprises of space exploration, from scientists to managers and decision-makers of the most important space agencies worldwide. 
However, does this mean that all the obstacles for the successful and continuous growth of plants in space have been removed?
The answer, from the perspective of plant biology research, is “no”, or, at least, “not yet”. Plant biologists believe that the results of Veggie and other similar experiments performed in the ISS open new questions and challenges to the scientific work. It is true that a higher plant did grow in space until an adult stage showing apparently the same shape, features and composition as they display on Earth. Nevertheless, we do not know how that plant overcame the cellular and molecular alterations that were produced in many physiological processes caused by the exposure to the space environment, according to many different reports (Herranz and Medina 2014; Medina 2020). Finding the keys to solve this paradox is one of the most exciting challenges of space biology research, with the global objective of enabling plant culture outside the Earth to support human space exploration.

Our research team is involved in this enterprise.
