The primary goal of the Mariner 10 was to study the atmosphere (if any), surface and physical characteristics of Mercury. Soon after leaving Earth orbit, the spacecraft returned striking photos of both Earth and the Moon as it sped to its first destination, Venus. The Earth-Moon system, as seen by NASA’s Mariner 10 spacecraft in 1973.

Mariner 10 was an American robotic space probe launched by NASA on 3 November 1973, to fly by the planets Mercury and Venus. It was the first spacecraft to perform flybys of multiple planets. [3] Mariner 10 was launched approximately two years after Mariner 9 and was the last spacecraft in the Mariner program.
The 10 Mariners visited Venus, Mars and Mercury for the first time, and later returned to Venus and Mars for a closer look. The final mission in the series, Mariner 10, flew past Venus before going on to Mercury for a total of three flybys. Mariner 9 became the first spacecraft to orbit another planet when it reached Mars in 1971.
Feb 5, 2019 · The spacecraft approached Venus from its night side, and passed within 3,584 miles of the planet on Feb. 5, 1974. During the fly-by, Mariner 10 performed flawlessly and sent back information about Venus’ atmosphere and environment and beamed back the first close-up images of the cloud-shrouded planet. Photographs taken in visible light ...
Nov 5, 2018 · Planetary scientists had learned a great deal about Venus from both Earth-based observations and spacecraft encounters. Two American spacecraft, Mariner 2 in 1962 and Mariner 5 in 1967, studied Venus during their fly-bys and revealed much about the planet’s atmosphere, showing it to be much hotter (527o C) and denser (75-100 atmospheres) than previously expected, and found only a very weak ...

On November 3, 1973, Mariner 10 was placed in a parking orbit after launch for approximately 25 minutes, then placed in orbit around the Sun en route to Venus. The orbit direction around the Sun was opposite to that of the Earth. Mariner 10 flew past Venus on February 5, 1974, at a distance of 4,200 kilometers (2,610 miles).
