Martian mountain may answer big question:

One Martian volcano is about three times Mount
Everest's height. But it's the small details that
two geologists are looking at.

The Mar­tian vol­ca­no Olym­pus Mons is about three times Mount Ever­est’s height. But it’s the small de­tails that ge­ol­o­gists Pat­rick Mc­Gov­ern and Jul­ia Mor­gan are look­ing at in think­ing about wheth­er the Red Plan­et ev­er had – or still sup­ports – life.

In sim­u­lat­ing the moun­tain’s forma­t­ion by com­put­er, Mc­Gov­ern and Mor­gan reached the con­clu­sion that an­cient wa­ter may still be trapped un­derneath. Their find­ings are pub­lished in Febru­ary’s is­sue of the re­search jour­nal Ge­ol­o­gy.
