Mars. Viking 1 and Viking 2 both landed on the planets surface in 1976.
Not yet. And there never will be a spacecraft landing on Neptune. The reason being, because Neptune is a gas giant, it has no solid surface for a spacecraft to land on. Neptune is also freezing cold. Electronic equipment such as a spacecraft would freeze up and malfunction in its atmosphere and most likely end up being consumed by the exposed molten ammonia core.
A moon or artificial object orbiting around a planet is called a satellite.
The presence or absence of spacecraft near Mars will have no effect whatsoever on the planet's gravitational field.
It was Mars 2, from the Soviet Mars Lander Program.
Jupiter ;)
yes
The Viking 1 and Viking 2 spacecraft took pictures of Mars in 1976 as part of NASA's Viking program. These missions were the first to successfully land and operate on the surface of Mars, providing valuable data and images of the planet.
pluto
The planet that the two Viking spacecrafts landed on in 1976 is Mars. They were the first spacecraft to successfully land and operate on the Martian surface, conducting experiments to search for signs of life.
The mariner spacecraft first landed on Mars 1971 I think.
No, because Uranus is a gaseous planet, which means it has no surface. Nowhere to land a spacecraft.
NASA's Viking 1 and Viking 2 landed on Mars in 1976.
that you can see the wonders of hashem and you can be the one to go up and see all the amazing creations
The Viking 1 spacecraft landed on Mars in 1976, followed by Viking 2 also in the same year. These missions were the first to successfully land and send back images and data from the Martian surface, providing valuable insight into the planet's geology and atmosphere.

No, because there is no surface to Jupiter, it is a gaseous planet with nowhere to land a spacecraft. Temperatures and pressure on Jupiter are also very extreme.
No spacecraft has visited all the planets.
