Our First Close Look at Venus

Mariner10_Venus47 years ago today, Mariner 10 took this first close-up photo of Venus.

The original image was taken using an ultraviolet filter. This photo has been color-enhanced to show the planet’s cloudy atmosphere as the human eye would see it. Venus’ atmosphere is rich in carbon dioxide and is perpetually blanketed by a thick veil of clouds. Its surface temperature approaches 900 °F.

Mariner 10 flew by Venus in 1974.
