Planet Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury. Billions of years later, Earth remains a blue marble while Mars has become a dry husk of its former self. While most of the desiccation resulted from the calamitous loss of Mars's atmosphere, the planet has kept some of its water.

However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen. ... Human survival on Mars would require living in artificial Mars habitats with complex life-support systems.

Mars may look hot, but don't let its color fool you -- Mars is actually pretty cold! In orbit, Mars is about 50 million miles farther away from the Sun than Earth. That means it gets a lot less light and heat to keep it warm.

Almost all water on Mars today exists as ice, though it also exists in small quantities as vapor in the atmosphere. ... Some liquid water may occur transiently on the Martian surface today, but limited to traces of dissolved moisture from the atmosphere and thin films, which are challenging environments for known life.

First Mars Mission
Mariner 9 was launched successfully on May 30, 1971, and became the first artificial satellite of Mars when it arrived and went into orbit. NASA's Viking Project found a place in history when it became the first mission to land a spacecraft safely on the surface of another planet.

Mars Exploration Rover
NASA's Mars Exploration Rover mission was a robotic space mission involving two Mars rovers, Spirit and Opportunity exploring the planet Mars. It began in 2003 with the launch of the two rovers to explore the Martian surface and geology; both landed on Mars at separate locations in January 2004.

Curiosity
Curiosity is a car-sized Mars rover designed to explore the Gale crater on Mars as part of NASA's Mars Science Laboratory mission.

How To Terraform Mars
Proponents of terraforming Mars propose releasing gases from a variety of sources on the Red Planet to thicken the atmosphere and increase the temperature to the point where liquid water is stable on the surface. These gases are called “greenhouse gases” for their ability to trap heat and warm the climate.
