Having successfully dropped off its three tons of hardware and supplies to the International Space Station (ISS) 12 hours earlier, the capsule-like craft returned laden with a more miscellaneous cargo. Inside were stem cells, a sextant designed for emergency navigation in deep space, and tissue chips created to help treat heart conditions on Earth. And nestled alongside them, 320 snippets of Merlot and Cabernet Sauvignon grapevines, individually wrapped in small bundles of soil and carefully placed in containers, each vine nestled inside its own beehive-like cell.
