Scientists have achieved a groundbreaking feat by capturing the first-ever views of Mars from a perspective replicating what an astronaut would see from the Worldwide Area Station (ISS).
NASA’s Mars Odyssey orbiter, tasked with making ready for future human missions to Mars, took a sequence of panoramic photos in Might from an altitude of roughly 250 miles (400 kilometers) – matching the ISS’s orbit round Earth.
The stitched-together photos reveal the Martian panorama beneath layers of clouds and mud, offering a singular and informative perspective.
The unprecedented view not solely presents gorgeous visuals of Mars but additionally aids scientists in gaining new insights into the planet’s ambiance. Whereas no astronauts are presently on Mars, the captured imagery gives an approximation of the view they may have when orbiting the Pink Planet.
Jonathan Hill of Arizona State College, operations lead for Odyssey’s Thermal Emission Imaging System (THEMIS), highlighted the importance of the attitude, stating:
“If there have been astronauts in orbit over Mars, that is the attitude they’d have. No Mars spacecraft has ever had this sort of view earlier than.”
Creating this view offered technical challenges that engineers at NASA’s Jet Propulsion Laboratory and Lockheed Martin Area addressed throughout three months of planning. The THEMIS digital camera, which is delicate to heat, often factors straight down, limiting its capability to seize a broader view of the Martian ambiance.
To beat this limitation, the spacecraft needed to be rotated virtually 90 levels, briefly interrupting communication with Earth in the course of the operation.

THEMIS, with its infrared capabilities, can map varied options on Mars, together with ice, rock, sand, and mud, and measure temperature modifications. The captured photos will contribute to enhancing fashions of Mars’ ambiance by revealing the positioning of water-ice clouds and mud layers in relation to one another.
The Odyssey mission goals to seize comparable photos sooner or later, offering insights into the Martian ambiance throughout a number of seasons.
Jeffrey Plaut, Odyssey’s venture scientist at JPL, described the achievement as akin to “viewing a cross-section, a slice via the ambiance,” emphasizing the added element that this distinctive perspective gives for scientific understanding.
