It's Just the Coffee Talking: That one time when NASA used common sense and listened to an astronaut when he said "guys, I think this is how this should be handled"

On Jan. 16, 2016, Expedition 46 Commander Scott Kelly shared photographs of a blooming zinnia flower in the Veggie plant growth system aboard the International Space Station. Kelly wrote, "Yes, there are other life forms in space! #SpaceFlower #YearInSpace"

This flowering crop experiment began on Nov. 16, 2015, when NASA astronaut Kjell Lindgren activated the Veggie system and its rooting "pillows" containing zinnia seeds. The challenging process of growing the zinnias provided an exceptional opportunity for scientists back on Earth to better understand how plants grow in microgravity, and for astronauts to practice doing what they’ll be tasked with on a deep space mission: autonomous gardening.

In late December, Kelly found that the plants "weren't looking too good," and told the ground team, “You know, I think if we’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 ‘Oh, maybe I should water the grass today.’ I think this is how this should be handled.”

The Veggie team on Earth created what was dubbed “The Zinnia Care Guide for the On-Orbit Gardener,” 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.

The zinnia seeds were delivered to the space station as part of the Veg-01 experiment in April 2014. The plant pillows containing the zinnia seeds were activated Nov. 16, 2015, in the Veggie plant growth system by NASA astronaut Scott Kelly during his one-year mission. The zinnias were watered and their growth was monitored for 90 days. The plants were harvested on Feb. 14, 2016, packaged and returned to Earth on the SpaceX CRS-8 Commercial Resupply Services Mission.
