新星 - Season 3 Episode 4 第 4 集 ()

The last fourteen years have been a revolution in our understanding of our place in the stars, the Solar System. Beginning in 1961 with a Russian spacecraft flying to Venus, quickening with the Apollo manned missions to the Moon, it came of age in the Spring of 1974, when there were six spacecrafts traveling simultaneously from the Earth to the planets. NOVA looks at the era of manned and unmanned exploration of the Solar System.
