Summary

Story summary

NASA's Mars Reconnaissance Orbiter (MRO) used a 120-degree roll to extend Shallow Radar (SHARAD) subsurface penetration, revealing a potential buried lake beneath about 1 mile of ice that may be briny.
The maneuver was developed with the Jet Propulsion Laboratory and Lockheed Martin to improve subsurface measurements.
The findings were published in Geophysical Research Letters.
The analysis builds on signals detected by the European Space Agency's Mars Express in 2018.
