NASAEstablished in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion." NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]” tabindex=”0″ role=”link”>NASA’s research on the ISS, including the XROOTS and VEG-05 experiments, focuses on growing food in space, essential for long-term missions.

Growing food aboard the International Space StationThe International Space Station (ISS) is a large spacecraft in orbit around the Earth that serves as a research laboratory and spaceport for international collaboration in space exploration. It was launched in 1998 and has been continuously occupied by rotating crews of astronauts and cosmonauts from around the world since 2000. The ISS is a joint project of five space agencies: NASA (USA), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). It orbits the Earth at an altitude of approximately 400 kilometers (250 miles), and provides a unique platform for scientific research, technological development, and human space exploration.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]” tabindex=”0″ role=”link”>International Space Station (ISS) is one of the many research investigations ripe for long duration spaceflight missions to the Moon and MarsMars is the second smallest planet in our solar system and the fourth planet from the sun.

NASA astronaut Frank Rubio recently shared the saucy story of two rogue tomatoes, which he had accidentally lost track of while harvesting for the eXposed Root On-Orbit Test System (XROOTS) experiment he conducted aboard the space station in 2022. The experiment uses hydroponic and aeroponic techniques to grow plants without soil or other growth media and could provide suitable solutions for plant systems needed for future space exploration missions.
Two rogue tomatoes have been recovered nearly a year after astronaut Frank Rubio accidentally lost track of them while harvesting for the XROOTS experiment, proving Rubio did not eat the tomatoes as they previously suspected. The rogue fruit was found in a plastic bag dehydrated and slightly squished with some discoloration but with no visible microbial or fungal growth.
While celebrating the space station’s 25th anniversary of operations, Expedition 70 crew members revealed they found the lost tomatoes, joking that Rubio did not eat the tomatoes as they suspected. Despite being nearly a year after the initial disappearance of the tomatoes, the fruit was found in a plastic bag dehydrated and slightly squished. Other than some discoloration, it had no visible microbial or fungal growth.
Extended Missions and Plant Research
During his U.S. record-breaking 371-day stay aboard station, Rubio also conducted another a-peeling experiment for the VEG-05 study, which helps address the need for a continuous fresh-food production system in space. This experiment used the space station’s Veggie facility to grow dwarf tomatoes focusing on the impact of light quality and fertilizer on fruit production, microbial food safety, nutritional value, and taste acceptability by the crew.

While the rogue tomatoes found from the XROOTS experiment will not be returning to Earth for analysis as they were discarded, plant research aboard space station continues with Plant Habitat-03, returning to Earth during the upcoming splashdown of SpaceXCommonly known as SpaceX, Space Exploration Technologies Corp. is a private American aerospace manufacturer and space transport services company that was founded by Elon Musk in 2002.

Plant Habitat-03 is one of the first multi-generational plant studies aboard the space station which could help researchers assess whether genetic adaptations in one generation of plants grown in space can transfer to the next. Results from this study could help identify genetic elements that increase the adaptability of plants to spaceflight providing insight into how to grow repeated generations of crops to provide food and other services on future space missions.
Benefits Beyond Food Production
The benefits of growing plants in space don’t stop there, astronauts report there are psychological benefits to time spent gardening, increasing their quality of life in space, and boosting their morale. Research aboard the space station is advancing the technology and scientific knowledge needed to successfully grow plants in space and help humans push the boundaries of space travel. This work also helps efforts to improve plants grown for food and other important uses here on Earth.
