For nearly a year, the world waited with baited breath for closure to a whodunit orbiting over 250 miles above everyone’s heads. Last week, the wait came to an end, clearing astronaut Frank Rubio’s name in the process. NASA posted a brief rundown of the saga detailing the multi-month search for the MIA produce.
Whatever happened to the disappearing dwarf tomatoes?
Back in November 2022, the International Space Station received a cargo delivery containing materials for Veg-05, a project aimed at furthering NASA researchers’ and astronauts’ understanding of hydroponic and aeroponic growing methods in microgravity, without soil. Access to fresh food will be an absolute necessity during humans’ long-term missions to the moon, Mars, and perhaps one day even beyond. Regular grocery runs won’t exactly be an option for the first residents of a potential Martian base, so growing healthy, nutritious produce like tomatoes will be a must.
Veg-05 offered astronauts a chance to investigate various growing techniques, which ultimately resulted in an impressive yield of dwarf tomatoes. At the time, astronauts including Frank Rubio intended to eventually taste test their ISS garden bounty. After picking the first two fruits off the vine, Rubio reportedly sealed them in a Ziploc bag and “velcroed it where I was supposed to velcro it,” he recounts in NASA’s video.
“And then I came back, and it was gone,” he continued.
While missing items are often recovered within the many ISS intake vents, Rubio estimates he spent somewhere between 18 and 20 hours of his spare time searching for the missing tomatoes, all to no avail. All the while, lighthearted rumors began to spread aboard the ISS that he simply ate the snacks without telling anyone. Rubio eventually returned to Earth on September 27 having broken the record for longest time spent in space (371 days), but still an accused man. During a subsequent December 6 livestream, however, ISS’s current residents broke the news: Rubio’s innocence could finally be confirmed.

“We can exonerate him; we found the tomato[es],” astronaut Jasmin Moghbeli said during last week’s broadcast.
Almost a year after their disappearance, the two tiny tomatoes were rediscovered—dehydrated, somewhat squishy, but very much intact and in their original Ziploc container.
That said, Rubio wasn’t the only one to miss out on eating the space-grown produce. In April 2023, NASA announced that while astronauts successfully grew their tomatoes, an unexpected risk of fungal and microbial contamination prevented anyone from actually tasting the final products. For what it’s worth, however, Rubio’s rediscovered tomatoes reportedly displayed no outward signs of contamination—perhaps a bit of cosmic karma
