On Monday, the United States celebrated the 40th anniversary of the first moon walk — but since 1969, the space race has widened far beyond U.S-Russian competition to include countries such as China, India and Japan.
Last September, China launched a 60-hour mission highlighted by the country’s first space walk. China hopes to land an unmanned rover on the moon by 2012 and a manned mission by around 2020, the same year the U.S. hopes to return to the moon.
