Because we're skilled enough to build rockets that can go to mars and land a vehicle there w/o having people along.
No, not yet. So far, we've only managed to send machines there.
Three spacecraft that have explored Mars are the Mars rovers Spirit, Opportunity, and Curiosity. These robotic vehicles have conducted various experiments to study the Martian surface, geology, and atmosphere since landing on the planet.
The Earth is the only planet people have landed on. Humans have landed on Earth's Moon and have landed robotic probes on the surfaces of Mars, Venus, and Saturn's Largest moon Titan.
No, Mars is not the most visited planet in our solar system. The most visited planet is Earth, followed by Mars and Venus. Multiple spacecraft have been sent to Mars to study its surface and atmosphere, but Earth remains the most visited due to human presence and satellite communications.
Nobody. We have sent robotic rovers to Mars, but never any people. No human has ever gone farther than the moon.
So far, no people have visited Mars, although robotic probes have been sent there in the search for scientific knowledge.
NASA has landed several robotic probes on Mars. No astronauts have visited Mars,and the Administration itself has remained on E St SW in Washington.
No. The only object in space that people have visited is the moon. The US has, however, sent several robotic rovers to Mars.
No humans have visited Mars yet. Only robotic spacecraft, like the Mars rovers, have been sent to explore the planet.
No, not yet. So far, we've only managed to send machines there.
Plenty of spacecraft, orbiters, landers, and rovers, have been sent to Mars.The Soviet Union, the United States, Europe, and Japan have sent craft to study the planet's surface, climate, and geology.See related link for a full list of exploration

No one went to Mars. It was an unmanned robotic expedition.
The Earth is the only planet people have landed on. Humans have landed on Earth's Moon and have landed robotic probes on the surfaces of Mars, Venus, and Saturn's Largest moon Titan.
2001 Mars Odyssey is a robotic spacecraft orbiting the planet Mars
Robotic missions help us understand mysterious features on the surface of Mars. Holes on Mars.
The only two objects in space that humans have visited are the Moon and Mars. This was achieved through various manned missions, including the Apollo missions to the Moon and robotic missions like the Mars rovers.
