Mars orbiter that launched from Florida captures 1st-ever pic of volcano above clouds
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, which launched on its mission about 24 years ago from Florida, 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.' Odyssey, which launched in 2021 from the Cape Canaveral Space Force Station in Florida, 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 stunning image of Mars' towering volcano Arsia Mons
NASA Captures Stunning Image of Mars' Towering Volcano Arsia Mons Piercing Through Dawn Clouds In a breathtaking new image, NASA's 2001 Mars Odyssey spacecraft has captured the massive Martian volcano Arsia Mons rising through pre-dawn clouds, offering an Earth-like yet entirely alien view from orbit. Photographed on May 2, 2025, the image shows Arsia Mons breaking through a blanket of water ice clouds, captured in a greenish atmospheric haze. The image was taken while the orbiter was turned 90 degrees midway around Mars — a rare maneuver to capture the planet's horizon, much like how astronauts see Earth from space. A Unique Vantage Point Mars Odyssey, the longest-operating spacecraft in orbit around another planet, used its THEMIS (Thermal Emission Imaging System) to collect this image. THEMIS, primarily designed to study surface temperature, has been used since 2023 to scan Mars' upper atmosphere and horizon. The latest capture showcases a rare and fleeting Martian weather pattern: early morning water ice clouds forming over the massive Tharsis Montes volcanoes. These clouds are most prominent during Mars' aphelion — when the planet is farthest from the Sun — creating a cloudy equatorial band, with Arsia Mons towering above. Colossal and Cloudy: Arsia Mons Standing at 20 kilometers high, Arsia Mons is nearly twice as tall as Mauna Loa in Hawaii, making it one of the tallest volcanoes in the solar system. Its height and shape encourage thick cloud formation each Martian morning as cold air condenses while rising up its slopes. NASA scientists, hoping to catch this exact moment, aimed Odyssey's camera at Arsia Mons — and the result did not disappoint. 'It's not just visually stunning; it's scientifically valuable,' said Jonathon Hill of Arizona State University, operations manager for THEMIS. Cracking the Code of Martian Weather The horizon view helps scientists understand seasonal and atmospheric changes on Mars. Michael D. Smith from NASA's Goddard Space Flight Center noted that these images are revealing critical patterns that could impact future mission planning, including spacecraft landings. THEMIS also detects visible and infrared light, helping identify subsurface water ice — a potential resource for future astronauts. It even observes Mars' moons, Phobos and Deimos, for surface composition data. A Mission That Keeps on Giving With support from NASA's Jet Propulsion Laboratory and Lockheed Martin Space, Odyssey continues to inspire after more than 20 years in orbit. THEMIS, designed by Arizona State University, remains a cornerstone in Martian exploration. Thanks to this new perspective, the Martian sky is offering more secrets — and scientists are ready to uncover them one image at a time.

Mars Orbiter Captures Rare View of Ancient Volcano Poking Above the Clouds
Floating in orbit above Mars, NASA's 2001 Mars Odyssey orbiter captured a panorama of the Red Planet's biggest volcanoes, Arsia Mons, peeking over a sea of clouds. The picturesque moment offers an exceptionally rare view of a Martian volcano, showing the landform at an angle in space that captures the planet's horizon. 'We picked Arsia Mons hoping we would see the summit poke above the early morning clouds. And it didn't disappoint,' Jonathon Hill, the operations lead for Odyssey's camera and a mission planner at Arizona State University's Mars Space Flight Facility, called the Thermal Emission Imaging System, or THEMIS, said in a statement. THEMIS can view Mars in both visible and infrared light. Launched in 2001, Odyssey has been circling around Mars for over two decades, studying the Martian surface. But in 2023, the orbiter began taking breathtaking panoramic views of the Martian horizon. Because THEMIS can't pivot to get these stunning views, the orbiter flips on its side, rotating a full 90 degrees. That way, it captured Mars' 'limb,' the edge of the planet's horizon. This is THEMIS' fourth limb observation since 2023. Odyssey captured the image on May 2, just before dawn. In it, Arsia Mons stands 12 miles (20 kilometers) high and measures 70 miles (450 km) in diameter. For comparison, Earth's tallest volcano, Mauna Loa, stands 6 miles (9 km) above the seafloor and measures 75 miles (121 km) in diameter. Arsia Mons is also one of Mars' cloudiest volcanoes and the southernmost of the three Tharsis volcanoes that form Tharsis Montes, or Tharsis Mountains. These mountains are often surrounded by water ice clouds, particularly early in the morning. The clouds form when air expands as it blows up the sides of the mountain and then rapidly cools. This view also allows scientists to study Martian weather and phenomena like dust clouds and how they change over the course of the seasons. Odyssey might be able to capture a few more of these panoramas before its eventual retirement, likely at the end of this year.
