Saturn
the megellan space probe was sent to venus.
The Mariner10 space probe and the Mercury Messenger space probe.
To orbit the planet Venus
Viking 2, a space probe sent to Mars, discovered evidence of water-ice in the Martian soil and photographed the planet's surface with its cameras. It also conducted experiments to search for signs of life in the Martian soil, but results were inconclusive.
The US sent the Voyager probes, Viking probes, and New Horizons probe to explore space, while the USSR sent the Venera probes, Luna probes, and the Mars probes. These space probes played crucial roles in advancing our understanding of the solar system and beyond.
The probe "Venera 7" sent by the USSR was the first. It landed on the planet Venus, in 1970 I think.
Yes. It is correct to say that viking was a name of a lunar probe.
First ever satellite to land on the planet Mars was a Russian probe called Mars 2. Albeit it did not land but crashed. The first successful probe to land on Mars was Mars 3 sent by the Russians, however the probe was operational for 15 minutes after landing on Mars. The first American probe to land on Mars was the Viking 1 on the 20th of July 1976.
if you mean CASSINI, then it was Saturn.
The Viking Space Probe was actually two different probes. Viking 1 and Viking 2 were used to explore Mars. The probes took photographs, did experiments and deployed instruments to the surface of Mars.
