Mars is the most accessible planet beyond the Earth-Moon system where sustained human presence is believed to be possible. The technical objectives of Mars exploration should be to understand what would be required to sustain a permanent human presence beyond Earth.
History :
Mars is the fourth planet from the Sun and the seventh largest:
Orbit : 227,940,000 km from Sun
diameter : 6,794 km
mass : 6.4219e23 kg
Mars (Greek: Ares ) is the god of War. The planet probably got this name due to its red color; Mars is sometimes referred to the Red Planet.
Mars has been known since prehistoric times. ...
The first spacecraft to visit Mars was Mariner 4 in 1965. Several others followed including Mars 2, the first spacecraft to land on Mars was the Viking lander in 1976. Mars Pathfinder landed successfully on Mars on 1997 July
4th .
Mars orbit is significantly elliptical. ... This has a major influence on Mars climate. While the average temperature on Mars is about -55°C, Martian surface temperatures range widely from as little as –133°C at the winter pole to almost 27°C on the day side during summer.
Though Mars is much smaller than Earth, its surface area is about the same as the land surface area of Earth.
Except for Earth, Mars has the most highly varied and interesting terrain of any of the terrestrial planets, some of it quite spectacular :
- Olympus Mons: the largest mountain in the Solar System rising 24 km above the surrounding plain.
