How do you know so much about the surface of Mars when no man has ever set foot on the planet?
We know the specific answers to specific questions that the probes were designed to find out. There have been several Mars landers, starting with two Viking probes that landed on July 20, 1976. (The first one was supposed to land on July 4, 1976 on the Bicentennial day - but there were Martian duststorms that lasted for weeks. So it landed on the anniversary of the Apollo 11 landing on the Moon.) Then the Mars Rover landed in the 1990's, and then two more - Spirit and Opportunity - five years ago. Between the satellite photography and the landers, we learned a LOT about Mars from our robot probes.
Who was on the viking 2 mission?
Viking 1 and Viking 2 were launched by the US in 1975. Both probes traveled to Mars, took photos of large expanses of the planet's surface from orbit, and released landers. The Viking 1 lander later transmitted the first pictures from the Martian surface. Both landers carried experiments designed to detect living organisms or life processes, but neither of them found any convincing signs of life. The Vikings and their landers were unmanned (robotic) spacecraft.
Which planets have been visited?
None of the 7 other planets in the solar system have been landed upon by humans. All of them have had space probes perform flybys to study and map them. Only Mars and Venus have had unmanned landers land on them.
Do space probes carry humans?
No, space probes are unmanned.
What do space probes explore in space?
Space probes explore space for a quite obvious reason; they are SPACE probes. They probe space.
Do space probes carry space landers?
Some space probes carry landers, but most do not.
How are space probes alike?
They are all alike in that they are in space.
Who went to Venus what is the name?
No one has been to Venus, though man made probes and landers have been sent there.
What are the three celestial bodies were landers have successfully landed?
Controlled landings by probes or spacecraft have been achieved on the Moon, Venus, and Mars.
Can you hear anything on mars?
Air is on mars' surface so sound can travel. Many landers/probes have landed with a microphone, and you can listen to it online.
Does mars have satellites orbiting it?
Yes, we have satellites orbiting mars. The last few probes that we've sent contained both landers and satellites intended to orbit the planet. They not only photograph the planet but they also serve as relays and retransmitters for the landers when communicating with Earth.
How Can Gold Dissvolve?
It can't. Gold is a noncorroding metal. This is why NASA uses it in space probes and landers for studying Mars and other planets, along with the rest of the Sol System.
When and how was Mars explored Has man explored on Mars?
Mars has been explored by telescopes, satellites, probes, landers and a few rovers. No human has ever set foot on Mars so far.

Was there any spaceship that passed through the asteroid belt?
Any of the several probes and landers that have ever reported data from Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, or beyond, had to pass through the asteroid belt.
