After nearly 20 years of operations, NASA’s Mars Reconnaissance Orbiter (MRO) is on a roll, performing a new maneuver to squeeze even more science out of the busy spacecraft as it circles the Red Planet. Engineers have essentially taught the probe to roll over so that it’s nearly upside down. Doing so enables MRO to look deeper underground as it searches for liquid and frozen water, among other things.
The new capability is detailed in a paper recently published in the Planetary Science Journal documenting three “very large rolls,” as the mission calls them, that were performed between 2023 and 2024.
The orbiter was originally designed to roll up to 30 degrees in any direction so that it can point its instruments at surface targets, including potential landing sites, impact craters, and more.
