Admire the first pictures of Solar System planets from NASA

The first pictures of planets are not always clear and sharp. But they are important milestones when human conquer universe.

On 07/14/1965, the spacecraft Mariner 4 flew pasted Mars, and this is the first time human saw close-up photos of the surface of another planet. Camera of Mariner 4 took 22 photos of the red planet, stored them on a tape and then successfully transmitted back to Earth.

Lunar Orbiter I shuttle of US took the first picture to Earth on 08/23/1966, when it is moved around the Lunar orbit. 1966 was a period of preparation when America sent a man on the Moon, so they launched the unmanned spacecraft to orbit the Moon, mapping to find landing sites for later.

Jupiter is the largest planet in the Solar System. Jupiter appeared dim in image sequences by the spacecraft Pioneer 10, as it approached the giant planet on 4/12/1973. This is the first close-up image of Jupiter.

This is the first picture of Venus taken by Mariner 10 spacecraft on 05/02/1974. The image mainly shows the colors of carbon dioxide (CO2) clouds covering around Venus, where the surface temperature reached almost 500°C.

Mariner 10 spacecraft of NASA for the first time photographed Mercury, the closest planet to the Sun, when it flew over the surface of the planet at a distance of 5.4 million km, on 24/03/1974.

Pioneer 11 spacecraft photographed Saturn and Titan moon (bottom, right) while the ship is moving through the outer ring of Saturn, in September 1979. Pioneer 11 also discovered new Saturn ring (F ring), measured the temperature on Titan and found it too cold for life to exist.

Voyager 2 spacecraft of NASA first photographed Uranus in 1986. The resulting image showed Uranus had almost uniform color and there were no cloud bands or storms like the other giant planet.

In 1989, Voyager 2 flew past Neptune and recorded images of "Large Dark Spot" in the southern hemisphere with the size equivalent "Large Red Spot" on Jupiter. This weather activity area is maintained by the winds with speeds up to 2,100 kilometers per hour, the strongest compared to other planets in the Solar System. Neptune has a ring system, but they are fainter than the famous Ring of Saturn.

New Horizons spacecraft captured the first close-up images of Pluto just July 13. The resulting image helped us to observe Pluto with more details than before. The dwarf planet is bronze color with black spots and a heart-shaped light area.
