The Hellas Quadrangle on Mars

The mapping of MC-28 has evolved through successive Mars exploration programs. Early telescopic observations were replaced by data from orbiters like Mariner 9, Viking, and later high-resolution missions like MRO.

The region features the Hellas Planitia, which is approximately 2,300 kilometers in diameter. It also contains various cratered terrains and evidence of glacial or periglacial processes.

The Hellas quadrangle (MC-28) is a defined region on the Martian surface. It is centered on the Hellas Planitia, a vast, low-lying impact basin that dominates the southern hemisphere's topography.

The quadrangle is significant for planetary science because the Hellas Basin provides a window into the crustal history of Mars. The depth of the basin allows for the study of atmospheric pressure and surface materials at lower elevations.

Geologists utilize remote sensing data, including thermal emission imaging and high-resolution stereo cameras, to identify stratigraphic units and landforms within the quadrangle.
