Soybeans in space? MN Soybean leaders visit NASA facility
Minnesota Ag Connection - 03/17/2023

Prior to Commodity Classic, American Soybean Association Director and Minnesota farmer George Goblish and Minnesota Soybean Director of Market Development Kim Nill participated in a field trip to the NASA Vegetable Production System (aka the “Veggie Lab”) facility near Orlando.

This NASA facility, overseen by Dr. Gioia Massa, has long researched the challenges of growing plants on the International Space Station (ISS). It is now addressing which crops will be grown during the upcoming NASA mission to Mars.

Kim Nill had been corresponding about NASA’s earlier growing of soybeans in space with the previous Director of NASA’s Veggie Lab, during the past two decades as part of the various positions he held within ASA and the U.S. Soybean Export Council.

“I was pleased to hear the Veggie Lab director state to our group that NASA plans for soybeans to be the first crop they plant on Mars as soon as they erect a greenhouse on that planet,” Said Kim Nill.

Dr. Massa noted one of the crucial lessons they learned growing plants on the ISS is that water and soil particles (e.g., from dead plant root removal post-harvest) must be controlled, so that neither dust nor water droplets “float” around the spacecraft in zero gravity. Thus, they invented sponge-like “pillows” to hold water near roots, and they invented the hollow plastic “screw” shown in photo, with which to remove dead plant roots post-harvest while containing the soil around those roots.

To save crucial space on the spacecraft, these “gardening tools” are created via an onboard 3D printer only several weeks after launch (by when the astronauts’ consumption of prepackaged food has cleared enough space for the growing of plants in the prior food-storage space). The 3D printer “plastic resin” is a mixture of very tiny wood chips suspended in polylactic acid (PLA), an oilseed-source plastic resin that is not compostable in spacecraft unless the tiny wood chips are mixed-in to it.
