Did you know that astronauts are growing lettuce in space?
NASA notes that “they are conducting plant research aboard the International Space Station because during future long-duration missions, life in space may depend on it. The ability of plants to provide a source of food and recycle carbon dioxide into breathable oxygen may prove critical for astronauts who will live in space for months at a time. In addition, plants provide a sense of well-being. At the McMurdo Station for research in Antarctica -- a site that in the dead of winter resembles the space station in its isolation, cramped quarters, and hostile environment -- the most sought after section of the habitat is the greenhouse.”
