Mars orbiter captures 1st-ever pic of volcano above clouds: It's twice as tall as Mauna Loa
A NASA spacecraft that has been circling Mars for more than two decades recently spotted something it never has before in well over 100,000 orbits of the Red Planet. On a morning horizon in May, the Odyssey spacecraft caught a stunning glimpse of one of the planet's largest volcanoes peeking out above a canopy of clouds. Known as Arsia Mons, the volcano dwarfs Earth's tallest volcanoes. Odyssey snapped some photos of the volcano in May, which NASA released in June in a blog post. Scientists at the U.S. space agency say the images provide far more than just a striking never-before-seen view of the Martian geography. In fact, studying the features detailed in Odyssey's photos could help NASA prepare for future crewed missions to Mars by better understanding the planet's weather and atmosphere. Here's a look at what Odyssey captured and what to know about the volcano, Arsia Mons. The new panorama captured by the Odyssey orbiter shows one of Mars' tallest volcanoes poking through clouds just before dawn. The image marks the first time a Martian volcano can be seen on the planet's horizon, offering what NASA says is a view akin to what astronauts on the International Space Station have of Earth. Odyssey's camera, called the Thermal Emission Imaging System (THEMIS,) is built to study the Martian surface. The THEMIS camera is equipped to view Mars in both visible and infrared light, the second of which allows scientists to identify subsurface areas that contain water ice. Such a resource would be an invaluable source of not only water, but a means to produce oxygen and fuel for crewed spacecraft when the first astronauts land on Mars. Odyssey rotated 90 degrees while orbiting Mars so that its camera had the correct angle to capture the shot, which, by revealing the horizon, allows scientists to observe seasonal changes on the Red Planet. Understandin the planet's weather, including its dust storms, could also help the space agency plan for future human spaceflights, according to NASA. The volcano Odyssey spotted is known as Arsia Mons, which is one of three on Mars forming the Tharsis Montes, or Tharsis Mountains. While clouds composed of carbon dioxide are common on Mars, the Martian mountain range is instead often surrounded by water ice clouds, especially in the morning, NASA says. Odyssey's latest horizon image, captured May 2, indicates that Arsia Mons stands 12 miles high. That's roughly twice as tall as Earth's largest volcano, Mauna Loa in Hawaii, which rises six miles above the seafloor. The southernmost of the Tharsis volcanoes, Arsia Mons is also the cloudiest of the three. The clouds, which form when air expands as it blows up the sides of the mountain and rapidly cools, are especially thick when Mars is farthest from the sun. The band of clouds that forms across the planet's equator at this time of year, called the aphelion cloud belt, is on prominent display in Odyssey's new panorama. 'We picked Arsia Mons hoping we would see the summit poke above the early morning clouds," Jonathon Hill, a researcher at Arizona State University who is the operations lead for THEMIS, said in a statement. "And it didn't disappoint.' Launched in 2001, Odyssey is the longest-running mission orbiting any planet besides Earth. The orbiter is also one of two spacecrafts orbiting Mars under threat of being axed under President Donald Trump's budget proposal for NASA. Managed by NASA's Jet Propulsion Laboratory in California, Odyssey completed its primary science mission from February 2002 through August 2004. Since then, the orbiter has set out to study Martian clouds, fog and frost while mapping the surface to pave the way for future crewed landings. The newest panorama, NASA said, represents the kind of science the orbiter began pursuing in 2023, when it captured the first of its now four high-altitude images of the Martian horizon.

NASA captures image of Mars' Arsia Mons volcano, nearly twice the height of Earth's tallest mountain
Image source: NASA Jet Propulsion Laboratory NASA has captured a breathtaking image of Arsia Mons, one of Mars' most massive volcanoes, towering nearly twice the height of any mountain on Earth. Captured at dawn by the 2001 Mars Odyssey orbiter, the photograph shows the volcano piercing through a layer of early morning haze, offering a surreal glimpse into the Martian horizon. Beyond its visual beauty, the image provides crucial scientific insights into Mars' volcanic past and atmospheric behaviour. Located in the Tharsis region, Arsia Mons' immense scale and persistent cloud cover make it a key subject for studying the Red Planet's evolving climate and geology. NASA's Mars Odyssey captures stunning image of Arsia Mons volcano NASA's Mars Odyssey spacecraft captured the breathtaking photo of Arsia Mons using its Thermal Emission Imaging System (THEMIS). The image is of the volcano above a green-colored haze of clouds passing over the Martian horizon at sunrise. The summit caldera of Arsia Mons is 120 kilometers wide, and it is larger than most volcanoes on Earth. For comparison, Arsia Mons is approximately 20 kilometers high, roughly twice as tall as Mauna Loa in Hawaii, the tallest volcano on Earth and roughly 9 kilometers higher than the sea bed. "We were hoping to grab Arsia Mons rising above morning clouds—and it surely didn't disappoint," joined Arizona State University's THEMIS operations lead Jonathon Hill. NASA studies Martian clouds and seasons using Arsia Mons observations Arsia Mons is located in the Tharsis province of volcanoes on Mars, which has three colossal volcanoes. The southernmost and typically cloudiest of the three is Arsia Mons. Its thick cloud cover is most common at Mars' aphelion—the time when Mars is farthest from the Sun. The clouds play an important role in Martian climate observation and phenomena like the planet's notorious dust storms. To record such seldom-observed horizon vistas, the Mars Odyssey orbiter performs a special 90-degree rotation maneuver so that its primarily ground-pointing camera may take pictures of the planet's atmospheric horizon. This special technique enables scientists to track dust and water-ice clouds and analyze their seasonal trends. Planetary scientist Michael D. Smith at NASA's Goddard Space Flight Center commented, "The horizon images exhibit large seasonal variations. These measurements are teaching us new things about how Mars' atmosphere varies with time." Why Arsia Mons volcano image matters In addition to its photographic attractiveness, the image of the Arsia Mons contains rich scientific information about Mars' geology and climate. Scientists gain a better understanding of predicting weather, dust storm formation, and the workings of larger-scale planetary phenomena by examining such volcanic formations and their interaction with the atmosphere. This image is particularly important as the space agencies of the world hasten plans to send man to Mars and increase robotic missions to the Red Planet. Such images pave the way for more safe and informed voyages to the Red Planet and take man one step closer to discovering its mysteries.

NASA Captures Mars Volcano Twice The Height Of Earth's Tallest Peaks
NASA's 2001 Mars Odyssey orbiter has captured a stunning picture of a 20-kilometer-high volcano, peeping through the clouds on the Red Planet. The image captured from the upper atmosphere at dawn, shows a green haze with Arsia Mons standing roughly twice as tall as Earth's largest volcano, Mauna Loa, located in Hawaii, which rises nine kilometers above the seafloor. At 120 kilometres wide, the Arsia Mons summit caldera is also larger than many volcanoes on Earth. The panorama image taken on May 2, using the Thermal Emission Imaging System (THEMIS), shows the planet's massive volcano for the first time. Arsia Mons is the southernmost of the Tharsis volcanoes and cloudiest of the three. 'We picked Arsia Mons hoping we would see the summit poke above the early morning clouds. And it didn't disappoint,' said Jonathon Hill of Arizona State University in Tempe, operations lead for THEMIS. Researchers said the clouds are especially thick over Arsia Mons when the Red Planet is farthest from the sun, a period called aphelion. "Understanding Mars' clouds is particularly important for understanding Martian weather and how phenomena like dust storms occur," NASA stated. Something big is peeking through Martian clouds. 🌋 The Odyssey orbiter captured a stunning view of Arsia Mons, a volcano that dwarfs the tallest ones here on Earth. This perspective helps scientists study how dust and ice clouds change over the seasons. — NASA JPL (@NASAJPL) June 6, 2025 Also Read | US Researcher Proposes Detonating Massive Nuclear Bomb Under Ocean To Save Earth The Odyssey orbiter was launched in 2001 and is regarded as the longest-running mission orbiting another planet. To click the picture, the orbiter rotates 90 degrees while in orbit so that its camera, built to study the Martian surface, can capture it cleanly. The angle of the camera allows scientists to see dust and water ice cloud layers, enabling them to observe changes over the course of seasons. 'We're seeing some really significant seasonal differences in these horizon images,' said planetary scientist Michael D. Smith of NASA's Goddard Space Flight Center in Greenbelt, Maryland. 'It's giving us new clues to how Mars' atmosphere evolves over time.'
