Leaving Mercury behind, the spacecraft looped around the Sun and headed back to its target, helped along by subsequent course corrections May 9, May 10 and July 2, 1974. Mariner 10 flew by Mercury once more on at 20:59 UT Sept. 21, 1974, at a range of about 29,869 miles (48,069 kilometers), adding imagery of the southern polar region.

Nov 3, 1973 · Mariner 10. The first mission to employ gravity assist, or using the gravity of a planet to alter a spacecraft's speed and trajectory to fly by its target planet, the Mariner 10 mission flew by both Venus and Mercury, snapping photos and collecting data. Launch Date. Nov. 3, 1973. Type. Flyby Spacecraft. Target. Mercury, Venus. Status.
Reprocessed Mariner 10 data was used to produce this image of Mercury. The smooth band is an area of which no images were taken. 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.
Jan 6, 2022 · The vehicle’s first planetary encounter was with Venus on 3 November 1973. Mariner 10 took some 4,000 photos of Venus, which revealed a nearly round planet enveloped in smooth cloud layers. The Venus flyby deflected Mariner 10’s trajectory towards Mercury, which it flew past at 756 km altitude on 29 March 1974.
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.
