NASA's Psyche spacecraft captured intriguing images of Mars' south polar cap during its flyby on May 15, 2023. The bright feature, initially resembling a storm, is actually the frozen south pole, measuring over 430 miles across. Ongoing studies continue to investigate the potential for underground liquid water beneath the ice, a key factor in understanding Mars' climate history.
- 01The south polar cap of Mars was photographed at a resolution of just over half a mile per pixel during Psyche's flyby.
- 02Psyche passed within 2,864 miles of Mars, using the planet's gravity to increase its speed by approximately 1,000 mph.
- 03Radar observations have suggested the possibility of underground liquid water, but newer studies indicate the signals may come from buried rock or dust instead.
- 04The polar caps of Mars are crucial for understanding the planet's climate history, with layers of ice and dust acting like pages in a history book.
- 05The Psyche mission aims to explore the asteroid Psyche, believed to be the exposed metallic core of a failed planet, with arrival expected in three years.

NASA's Psyche spacecraft recently provided stunning new images of Mars' south polar cap during its flyby on May 15, 2023. The bright white feature, which initially appears to be a storm or cloud, is actually the frozen south pole, spanning over 430 miles. Psyche captured these images at a resolution of just over half a mile per pixel while passing within 2,864 miles of the Martian surface, using the planet's gravity to boost its speed by approximately 1,000 mph. Scientists are particularly interested in this region due to ongoing debates about what lies beneath the ice. While earlier radar observations hinted at the presence of underground liquid water, newer data suggests the signals might indicate buried rock or dust layers instead. The polar caps are essential for understanding Mars' climate history, as they contain layers of water ice, frozen carbon dioxide, and dust that record changes over billions of years. The Psyche mission, which aims to explore the asteroid Psyche, is expected to arrive at its destination in three years, but the spacecraft will continue to gather data on Mars during its journey.
