Scientists believe that astronauts will suffer without the variety offered by fresh vegetables. The answer is to grow at least some of the food. On a short trip it is imagined that astronauts will eat vegetables such as lettuce, spinach and carrots grown in a refrigerator-sized unit known as a "salad machine". On longer journeys they will actually grow vegetables in greenhouses on Mars. Martian astronauts will eat a vegetarian diet since it will not be practical to raise animals.
