Deep Hole Found on Mars

Deep hole has been found on Mars and scientists believe that life may be found within this hole. The hole is estimated to be 330 feet across (100 meters); such information was gathered through the high resolution feature of The Mars Reconnaissance Orbiter (MRO). NASA says they see two dark spots near the equator and believe they are entrances to underground caves. So far the NASA Mars Odyssey and its Thermal Emission Imaging System (THEMIS) are near by, allowing exploration of such areas to be pursued. Scientists say that holes such as the one mentioned earlier and caves are highly targeted locations on Mars due to the likelihood of microbial life being found in such locations.
