Scientists at the 55th Lunar and Planetary Science Conference in Texas revealed a groundbreaking discovery: a colossal volcano and potential glacier ice sheet found in Mars' Tharsis volcanic province.
Orbiting spacecraft, including Mariner 9 and Mars Global Surveyor, have imaged the eastern region of Mars' Tharsis province extensively since 1971. However, a massive volcano and potential glacier ice, now dubbed the "Noctis volcano," remained unnoticed until recent observations.
Provisionally named "Noctis volcano," this structure stands as one of Mars' largest, towering over 29,000 feet in elevation and stretching 280 miles in width. This surpasses even the highest peaks on Earth, Mount Everest, which stands at an elevation of 29,032 feet (8,849 meters). Its location, nestled between Noctis Labyrinthus and Valles Marineris, makes it an intriguing area for further exploration.
Evidence suggesting the volcanic origins of the Noctis volcano includes elevated mesas forming an arc around the central summit, indicative of volcanic activity. Additionally, remnants of a collapsed crater, lava flows, and pyroclastic deposits further support its volcanic identity.
A recent study highlights the presence of a thin, recent volcanic deposit covering glacier ice, indicating Mars' complex geological history. The study's lead author, Dr. Pascal Lee, underscores the significance of this find for understanding Mars' evolution and potential for life.
The discovery of the Noctis volcano opens new avenues for studying Mars' geologic evolution and searching for signs of life. The presence of glacier ice near the equator presents opportunities for future robotic and human exploration, offering access to essential resources.
This study utilized data from various Mars missions, including Mariner 9, Viking Orbiter 1 and 2, and Mars Reconnaissance Orbiter, emphasizing the collaborative nature of planetary exploration.

According to a report by SETI, the Noctis volcano's complex history, marked by fracturing, thermal erosion, and glacial activity, provides insight into Mars' geological processes over time. The volcano's enduring presence raises questions about its volcanic activity timeline and potential for future eruptions.
As scientists delve deeper into the mysteries of the Noctis volcano, it emerges as a promising site for studying Mars' past, present, and future. Its unique geological features and potential glacier ice offer tantalizing prospects for future missions and Astro biological research.
