Abstract: Physiological adaptive changes may occur in astronauts under the particular space environmental conditions such as microgravity, noise, vibration, and hermetic cabin during long-term manned space flight. Space nutrition supply is an important research issue for mankind to explore space, especially in the case of long-term manned space flight. This paper reviews recent progress in research on space nutrition in the United States, Russia and other countries for long-term manned space flight activities such as space station, manned lunar landing and manned Mars exploration. Compared with mid- and short-term manned space flight mission, space nutrition for long-term manned space flight is more focused on improving nutritional balance, resource recycling, healthcare function and sensory acceptance.

Key words: space nutrition, space food, manned space flight, space station, manned landing on the moon, manned Mars exploration
