Baby Zucchini Sprouts

Astronaut Don Pettit described his zucchini growing experiment aboard the ISS in his blog. He writes: "We have two new crewmates, 'Sunflower' and 'Broccoli'. Sunflower has a long stem for the size of his leaves. He is standing tall. Broccoli is small and weak. His sprout is so small that without the normal gravitational signals, surface tension forces keep his cotyledons from breaking free from the damp pigmat medium. Effectively, his first two leaves are glued down to a wet layer. Within a day or two mold takes over and the poor sprout dies. It grieves me to see them die. Life can be tough on the frontier."
