Mars

(well-explored planet in the solar system)

Mars is the fourth solar system planet from the Sun and the second smallest. Characteristics:

  • 1.5 AU - orbital radius.
  • .1 Earth masses.
  • .5 Earth radii.

It has two small Moons, Phobos and Deimos both smaller than 25km in radius.

Far more space missions have been sent to Mars than to any other planet, more than 40, beginning in the 1960s with the NASA Mariner and Viking programs and the Soviet Mars program. Recent years have had orbiters (e.g., NASA's Mars Reconnaissance Orbiter (MRO)) and rovers (e.g., NASA's Curiosity) and other missions Swinging By.

Future missions and proposals include missions from numerous countries: Mars 2020 from NASA, and others by the EU, Japan, Russia, China, and other countries, including the ExoMars, rover mission from the European Space Agency and Russia.
