Exploring Shallow Subsurface of Mars and Introducing the GPR Technique for Planetary Sciences(Exploring Mars beyond the Surface Features)

Wajahat Ali and Sean R Shieh

Several geophysical techniques are available for the investigation and characterization of shallow subsurface. Most commonly used are electrical methods, seismic refraction and reflection methods, multichannel analysis of surface waves, gravity, magnetic, electromagnetic induction and ground penetrating radar. Mars is the one of the terrestrial planet, under discussion from several years due to interesting facts obtained from surface features including the evidences for the presence of water. Surface features on Mars include plans, mountains, impact crater, lava flows and dust cover. The possibility of life on the Mars is a question mark which is yet to be defined. In this article GPR technique is proposed for planetary missions to explore the subsurface of Mars. Ground Penetrating Radar (GPR) is a recent technology which provides high resolution picture for near surface structures. Due to the small size, light weight, high resolution, and simple operational system the GPR is supposed to be a best tool for the exploration of near surface features and hydrology of Mars. Launching a planetary mission at Mars with GPR could provide the information about the subsurface structures. This information could be used to define many question marks about red planet.
