there might be life in mars
Mars has been explored by telescopes, satellites, probes, landers and a few rovers. No human has ever set foot on Mars so far.
The solar system is studied largely by observations using telescopes, helioscopes, and related equipment; the Earth itself yields many clues about the nature of the solar system and can be studied directly. For chemistry and properties of distant planets, probes can be sent to the surface (such have already been sent to surfaces of Mars, Venus, the Moon, Titan, etc.) or to perform fly-bys to take pictures, radar surface mapping through dense clouds, perform spectroscopic analyses, infrared imaging, etc.
no
venus, mars
the mars is the number four in the planets
Probably because it's the closest planet to the Earth.
Mars was discovered long before telescopes were invented. It is one of the classical planets, discovered in ancient times.
You can see some of the planets with the naked eye. The following can be seen easily; they appear as bright stars: Mercury, Venus, Mars, Jupiter, Saturn. To see other planets, telescopes are required.
The answer is mars.

human:the moon,and mars Robot:moon,mars,and the others,but no landings on gas giants
venus, mars
Mars, Pluto ( a dwarf planet )... A spaceship is going to Pluto and learn more about the planet by taking pictures.

Christiaan Huygens is someone who studied Mars. He was a Dutch scientist and mathematician.
