Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s 2001 Mars Odyssey orbiter captured this single image of Olympus Mons, the tallest volcano in the solar system, on March 11, 2024. Besides providing an unprecedented view of the volcano, the image helps scientists study different layers of material in the atmosphere, including clouds and dust.NASA/JPL-Caltech/ASU The 23-year-old orbiter is taking images that offer horizon-wide views of the Red Planet similar to what astronauts aboard the International Space Station see over Earth.
NASA’s longest-lived Mars robot is about to mark a new milestone on June 30: 100,000 trips around the Red Planet since launching 23 years ago. During that time, the 2001 Mars Odyssey orbiter has been mapping minerals and ice across the Martian surface, identifying landing sites for future missions, and relaying data to Earth from NASA’s rovers and landers.
Scientists recently used the orbiter’s camera to take a stunning new image of Olympus Mons, the tallest volcano in the solar system. The image is part of a continuing effort by the Odyssey team to provide high-altitude views of the planet’s horizon. (The first of these views was published in late 2023.) Similar to the perspective of Earth astronauts get aboard the International Space Station, the view enables scientists to learn more about clouds and airborne dust at Mars.
Taken on March 11, the most recent horizon image captures Olympus Mons in all its glory. With a base that sprawls across 373 miles (600 kilometers), the shield volcano rises to a height of 17 miles (27 kilometers).
“Normally we see Olympus Mons in narrow strips from above, but by turning the spacecraft toward the horizon we can see in a single image how large it looms over the landscape,” said Odyssey’s project scientist, Jeffrey Plaut of NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission. “Not only is the image spectacular, it also provides us with unique science data.”
In addition to offering a freeze frame of clouds and dust, such images, when taken across many seasons, can give scientists a more detailed understanding of the Martian atmosphere.
This infographic highlights just how much data and how many images NASA’s 2001 Mars Odyssey orbiter has collected in its 23 years of operation around the Red Planet.NASA/JPL-Caltech A bluish-white band at the bottom of the atmosphere hints at how much dust was present at this location during early fall, a period when dust storms typically start kicking up. The purplish layer above that was likely due to a mixture of the planet’s red dust with some bluish water-ice clouds. Finally, toward the top of the image, a blue-green layer can be seen where water-ice clouds reach up about 31 miles (50 kilometers) into the sky.
How They Took the Picture
Named after Arthur C. Clarke’s classic science-fiction novel “2001: A Space Odyssey,” the orbiter captured the scene with a heat-sensitive camera called the Thermal Emission Imaging System, or THEMIS, which Arizona State University in Tempe built and operates. But because the camera is meant to look down at the surface, getting a horizon shot takes extra planning.
By firing thrusters located around the spacecraft, Odyssey can point THEMIS at different parts of the surface or even slowly roll over to view Mars’ tiny moons, Phobos and Deimos.
The recent horizon imaging was conceived as an experiment many years ago during the landings of NASA’s Phoenix mission in 2008 and Curiosity rover in 2012. As with other Mars landings before and after those missions touched down, Odyssey played an important role relaying data as the spacecraft barreled toward the surface.
Laura Kerber, deputy project scientist for NASA’s Mars Odyssey orbiter, explains how and why the spacecraft in May 2023 captured a view of the Red Planet similar to the International Space Station’s view of Earth.

Scientists were intrigued when they noticed that positioning Odyssey’s antenna for the task meant that THEMIS would be pointed at the planet’s horizon.
“We just decided to turn the camera on and see how it looked,” said Odyssey’s mission operations spacecraft engineer, Steve Sanders of Lockheed Martin Space in Denver. Lockheed Martin built Odyssey and helps conduct day-to-day operations alongside the mission leads at JPL. “Based on those experiments, we designed a sequence that keeps THEMIS’ field-of-view centered on the horizon as we go around the planet.”
The Secret to a Long Space Odyssey
What’s Odyssey secret to being the longest continually active mission in orbit around a planet other than Earth?
“Physics does a lot of the hard work for us,” Sanders said. “But it’s the subtleties we have to manage again and again.”
These variables include fuel, solar power, and temperature. To ensure Odyssey uses its fuel (hydrazine gas) sparingly, engineers have to calculate how much is left since the spacecraft doesn’t have a fuel gauge. Odyssey relies on solar power to operate its instruments and electronics. This power varies when the spacecraft disappears behind Mars for about 15 minutes per orbit. And temperatures need to stay balanced for all of Odyssey’s instruments to work properly.
“It takes careful monitoring to keep a mission going this long while maintaining a historical timeline of scientific planning and execution — and innovative engineering practices,” said Odyssey’s project manager, Joseph Hunt of JPL. “We’re looking forward to collecting more great science in the years ahead.”

Two large asteroids will safely pass Earth this week, a rare occurrence perfectly timed to commemorate this year's Asteroid Day. Neither poses any risk to our planet, but one of them was only discovered a week ago, highlighting the need to continue improving our ability to detect potentially hazardous object in our cosmic neighbourhood.

Comicpalooza, the largest annual pop culture festival in the southern United States, is home to thousands of comic book, science, anime, and gaming fanatics in Houston. Guests have the opportunity to celebrate their passions through a variety of entertainment, panels, and meet and greets.
NASA’s Johnson Space Center has participated in Comicpalooza’s festivities for the last decade, giving attendees the chance to interact with NASA experts and learn more about human space exploration and the agency’s mission.
Comicpalooza guests listen to a presentation by NASA astronaut Marcos Berríos at the agency’s exclusive booth and stage area.NASA/Robert Markowitz Over 52,000 fans attended this year’s Comicpalooza, held May 24-26 at Houston’s George R. Brown Convention Center. NASA shared with them the exhilarating future of the Artemis campaign that will take humans further in space exploration than ever before, plans for human exploration of the Moon and Mars, and showcased innovative spacesuits, lunar terrain vehicles, and spacewalk tools. Fans also had an opportunity to meet and take photos with NASA astronaut Marcos Berríos.
NASA astronaut Marcos Berríos talks about his journey to becoming an astronaut and experiences to date during a presentation at 2024 Comicpalooza. NASA/Robert Markowitz The NASA exhibit featured immersive experiences with the Extravehicular Activity and Human Surface Mobility Program; Exploration Architecture, Integration, and Science Directorate; Human Health and Performance Directorate; and STEM engagement programs. These unique exhibits provided guests with insight into the exciting opportunities and discoveries ahead for human spaceflight. NASA’s presence at Comicpalooza also caught the attention of legendary Hollywood actor Christopher Lloyd, who met NASA officials and participated in a tour of Johnson Space Center after the event concluded.
Johnson Space Center volunteers and NASA experts who led interactive exhibits and panel discussions as part of the agency’s presence at 2024 Comicpalooza.NASA/Robert Markowitz NASA’s exclusive Comicpalooza stage featured 13 unique panels and discussions from agency experts, programs, and Berríos. These panels included:
