So far, station crews have harvested peas, leafy greens and a variety of dwarf wheat, all of which have now been certified as safe to eat, according to Russian researcher Margarita Levinskikh, who spoke this week at a conference in Moscow, the Russian news service RIA Novosti reports.
After undergoing repairs this year, the greenhouse will be restocked with rice, tomatoes and bell peppers, RIA said.
In addition to eventually supplementing the crew's diet, the crops will be analyzed to see if they genetically change in space.
