The southernmost member of this group of shield volcanoes is called Arsia Mons (the other two being Ascraeus Mons and Pavonis Mons).
That would make Mars's giant mid-latitude mountains -- Ascraeus Mons, Pavonis Mons and Arsia Mons.
The High Resolution Imaging Science Experiment camera aboard NASA's Mars Reconnaissance Orbiter found the heart-shape on the south of the huge shield volcano Ascraeus Mons which measures approximately 200 meters across, Discovery News reported.
Morning clouds and frost can sometimes settle in the broad, low plains of this region, making the giant Tharsis volcanoes Arsia Mons, Pavonis Mons, and Ascraeus Mons, as well as nearby Olympus Mons, appear as dark spots above the bright plains.
Here we report on specific white clouds forming in the afternoon over Alba Patera, Olympus Mons (aka Nix Olympica), the Tharsis Montes (Ascraeus Mons, Pavonis Mons and Arsia Mons) and Elysium Mons.
The most obvious volcanic features on Mars are four extremely large ([?]600 km diameter, heights up to >20 km) shield volcanoes (Olympus Mons, Ascraeus Mons, Pavonis Mons, and Arsia Mons) with the same general morphology as basaltic shield volcanoes found on Earth (Fig.
Estienne made a similarly uncompromising decision when he chose that the first text his reader would encounter on turning the title-page of the Thesaurus would be a poem by himself, in Greek, starting with a reference to a certain Ascraeus: "`The tongue's best treasure,' Ascraeus said...." (46) The first words of the introduction to the reader were a couplet, also in Greek, again citing Ascraeus as the authority: "`The tongue's best treasure among men is when it is sparing, and its greatest charm is when it goes in measure,' as Ascraeus the poet once sang." (47) Ascraeus was not exactly the name of a poet; Estienne's readers must remember that just as Theocritus was supposed to have been born in Syracuse, so Hesiod had been born in a small town called Ascra.
Ovid in referring to Hesiod used the adjective "ascraeus." The poet, himself heir to the traditions of minstrelsy in this colony of Hellas, says that he once sailed to Chalcis in Euboea where he competed in a poetry contest held by Amphidamas and won the prize, a tripod with handles, which he gave to the Muses of Helicon.
"Combined with the varying height of the volcanoes, we can say that Arsia Mons is the oldest, then Pavonis Mons formed and finally Ascraeus Mons," said Mikael Beuthe of the Royal Observatory of Belgium and lead author of the paper.
Here we report on specific white clouds over Alba Patera, Olympus Mons ('Nix Olympica'), the Tharsis Montes (Ascraeus Mons, Pavonis Mons and Arsia Mons) and Elysium Mons (Figures 14-16; and Part I, Figures 4F, 5).
