In solar system, Mars which has the most similar environment with the Earth has been steadily studied for the purpose of habitable environment for the future manned exploration and settlement. During the daytime, Martian ionosphere can be used for the ground-ground communications between lander and rover through the reflection of the radio wave from ionosphere. In addition, researches about Martian ionosphere provide the link of revolution of water and atmosphere. Martian ionospheric observations were performed by the occultation experiments onboard Mariner, Mars, Viking series during early Martian explorations as well as recent Mars Global Surveyor. Low frequency radar and plasma analyzer are on board Mars Express and Viking-1, 2 lander obtained the only vertical plasma density profile during their entry phase. In this paper, we studied the characteristics of scientific payloads observing Martian ionosphere and then analyzed the usability of ionospheric research according to the communication and climate on Mars.

Endlessly, mankind has been pursuing its dream toward understanding and conquering our neighboring planet, Mars since Mars has been identified as a planet. After the development of advanced science and technology of human race in 1960, the Union of Soviet Socialist Republics (USSR) had initiated its dream toward Mars and finally at present mankind acquires numerous important clues of Mars through over forties of space programs toward Mars. Furthermore, mankind takes its effort in colonizing Mars within several decades. This manuscript introduces the history of space mission programs of Mars up to date and major scientific findings to understand the Mars.
