This animation depicts NASA's Mars Reconnaissance Orbiter (MRO) performing what's called a "very large roll": a 120-degree roll that can increase the capabilities of the spacecraft's subsurface radar instrument, called Shallow Radar, or SHARAD. Very large rolls boost SHARAD's signal by 10 times or more, giving scientists a clearer and deeper look below the Martian surface than MRO has ever had before. The orbiter was designed to roll up to 30 degrees in any direction so that it can point its instruments at surface targets. These standard rolls give cameras like the High-Resolution Imaging Sci…
