During its flyby of Venus, Mariner 10 discovered evidence of rotating clouds and a very weak magnetic field. Using a near-ultraviolet filter, it photographed Venus's chevron clouds and performed other atmospheric studies. The spacecraft flew past Mercury three times.
On Feb. 5, 1974, the spacecraft began returning images of Venus, the first picture showing the day-night terminator of the planet as a thin bright line. Overall, Mariner 10 returned 4,165 photos of Venus and collected important scientific data during its encounter. The closest flyby range was 3,584 miles (5,768 kilometers) at 17:01 UT Feb. 5, 1974.

Mariner 10 flew past Venus on February 5, 1974, at a distance of 4,200 kilometers (2,610 miles). More than 4,000 photos of Venus revealed a nearly round planet enveloped in smooth cloud layers. Venus exhibited a slow rotational period of 243 days and had only 0.05 percent of Earth's magnetic field.
