This orange beauty, bathing in natural sunlight for the first time, is the first Zinnia flower to have ever grown entirely in space. It’s part of the VEG-01 experiment on the International Space Station.
The Veggie experiments will allow the crew members to begin the first steps of in-orbit food production as well as educational outreach and recreation for long-duration missions. The experiment allows scientists to gain a better understanding of plant cultivation and will help determine ways to carry out self-sustaining life support systems during long distance space travel, possibly to Mars.
The facility has previously grown lettuce which was consumed by the crew last year. The next set of crops, called VEG-03, has two types of Chinese cabbage and more romaine lettuce. It will arrive at ISS in March via SpaceXâ€™s CRS-8 mission. In 2018, NASA will send a set of dwarf tomato plants to ISS and we could witness crew members eating the first space salads.
Surprising, the Zinnia flowers almost died from over watering, a mold outbreak, and too much bureaucracy from NASA:
In late December, Kelly found that the plants “weren’t looking too good,” and told the ground team, â€œYou know, I think if weâ€™re going to Mars, and we were growing stuff, we would be responsible for deciding when the stuff needed water. Kind of like in my backyard, I look at it and say â€˜Oh, maybe I should water the grass today.â€™ I think this is how this should be handled.â€
The Veggie team on Earth created what was dubbed â€œThe Zinnia Care Guide for the On-Orbit Gardener,â€ and gave basic guidelines for care while putting judgment capabilities into the hands of the astronaut who had the plants right in front of him. Rather than pages and pages of detailed procedures that most science operations follow, the care guide was a one-page, streamlined resource to support Kelly as an autonomous gardener. Soon, the flowers were on the rebound, and on Jan. 12, pictures showed the first peeks of petals beginning to sprout on a few buds.
