Many discoveries have been made on Mars lately.  First, a giant pool of water ice was located at the south pole of the Red Planet and now seven possible cave entrances were found on the surface of the planet. 

The authors say that the possible discovery of caves on the Red Planet is significant.

The caves may be the only natural structures capable of protecting primitive life forms from micrometeoroids, UV radiation, solar flares and high energy particles that bombard the planet's surface.
