#What is the density of water series

Across the Red Planet's history, the axial tilt of the planet's poles is understood to have varied quite chaotically. The ice's existence could be the result of Mars' wandering axis.

Curiosity rover spots Starfleet symbol on Red Planet Strange underground polygons on Mars hint at Red Planet's wet past 'How long did these ice deposits form, and what was Mars like at the time?' 'This latest analysis challenges our understanding of the MFF and raises as many questions as answers,' said Colin Wilson, who is an ESA Project Scientist for Mars Express and the Trace Gas Orbiter, in the statement. The presence of subsurface water-ice at low and equatorial latitudes hints at how Mars' climate was very different in the distant past. Additionally, the remains of ancient glaciers, called relict glaciers, have been spotted in Eastern Noctis Labyrinthus, which is just 7.3 degrees south of the equator. More recently, ESA's Trace Gas Orbiter detected hydrogen from water ice just beneath the surface of Candor Chaos, which is a segment of the immense rip in the surface of Mars that we call Vallis Marineris. Meanwhile, early in its mission, Mars Express detected abundant water-ice extending down into the mid-latitudes, and NASA's Mars Odyssey even found clues to the presence of water in the MMF in 2009. Sub-surface ice has been found in plentiful quantities on Mars before NASA's Phoenix mission dug up ice just beneath the dusty surface at the lander's polar landing site in 2008. More pertinent is the question of how the water ice ended up buried at the equator. (Image credit: CReSIS/KU/Smithsonian Institution)

The graph shows that the ice deposit is thousands of meters high and hundreds of kilometers wide. The graph below shows the shape of the land and the structure of the subsurface, with the layer of dry sediments (likely dust or volcanic ash) in brown and the layer of suspected ice-rich deposits in blue. In this image, the white line on Mars' surface (top) shows a stretch of land that was scanned by MARSIS. Instead, the deposits are low in density and fairly transparent to MARSIS' radar, which is exactly how one would expect water ice to appear in the data. 'This would create something far denser than what we actually see with MARSIS.' 'Given how deep it is, if the MFF was simply a giant pile of dust, we'd expect it to become compacted under its own weight,' said Andrea Cicchetti of the National Institute for Astrophysics in Italy in a press statement. New observations by MARSIS, which is a subsurface radar on board Mars Express, now have the answer - and it's not dust.

The MFF consists of a series of wind-sculpted deposits measuring hundreds of kilometers across and several kilometers high. This perspective view shows Eumenides Dorsum, part of Mars’s Medusae Fossae Formation (MFF).
