The research was conducted using an instrument on board the NASA Mars Reconnaissance Orbiter that allowed an unprecedented examination of “the most recent Martian ice age recorded in the planet’s north polar ice cap,” according to a NASA press release. Research was led by planetary scientist Isaac B. Smith at the Southwest Research Institute in Boulder, Colorado. “We found an accelerated accumulation rate of ice in the uppermost 100 to 300 meters of the polar cap,” Mr. Smith said in a statement on the SRI website. “The volume and thickness of ice matches model predictions from the early.
