A Water Ice Map for Mars
Dec 10, 2019
This rainbow-colored map shows underground water ice on Mars. Cool colors represent less than one foot (30 centimeters) below the surface; warm colors are over two feet (60 centimeters) deep. Sprawling black zones on the map represent areas where a landing spacecraft would sink into fine dust. The outlined box represents the ideal region to send astronauts for them to be able to dig up water ice.
The map was created by combining data from multiple NASA orbiters, including the Mars Reconnaissance Orbiter and its Mars Climate Sounder instrument; Mars Odyssey and its Thermal Emission Imaging System; and the Mars Global Surveyor.
