Phobos 360

The innermost moon of Mars, Phobos, is seen here in full 360 degree glory. The images were taken by the High Resolution Stereo Camera (HRSC) on ESA's Mars Express at various times throughout the mission's 10 years.

The moon's parallel sets of grooves are perhaps the most striking feature, along with the giant 9 km-wide Stickney impact crater that dominates one face of the 27 x 22 x 18 km moon.

The origin of the moon's grooves is a subject of much debate. One idea assumes that the crater chains are associated with impact events on the moon itself.

Another idea suggests they result from Phobos moving through streams of debris thrown up from impacts 6000 km away on the surface of Mars, with each 'family' of grooves corresponding to a different impact event.

Mars Express has imaged Phobos from a wide range of distances, but will make its closest flyby yet on 29 December 2013, at just 45 km above the moon.

Although this is too close to take images, gravity experiments will give insight into the interior structure of Phobos.

Wheres the Monolith? and why is there a  ''blurred'' out section at :21 to :29?

The game Doom made this moon and Deimos known to many.  We already know about it and what we'll find there.

So... where is the base from Doom located? the Big crater at the right side at 0:08 i assume?

[vinayseth]

So where's the monolith that Buzz Aldrin talked about?

[nutier]

this phobo is a mysterious thing flying in the space as an asteroid .
Merry Christmas !

Scars all over. But still going strong. GO Phobos !!! \o/

min 0:24 an entire section of the moon is blurred out...ESA, please fix that. :(

Videos are nice, although I prefer Photos of Phobos

Dónde está el MONOLITO?? porqué lo borraron

[pigozz]

Monolith, Straight "airport-like" lines, two probes lost under strange circumstances when trying to explore it, weigh much less than it should (asi if its hollow) ... phobos definately IS a strange object

At 27 second, center of screen is what appears to be a large hole with dust or gas coming out of it. Is nobody interested in that?
