NASA’s Mars Odyssey orbiter has supplied new panoramic photographs of Mars and its moon Phobos, providing recent insights into the Martian panorama and environment.
The Odyssey orbiter captured clouds and mud within the Purple Planet’s skies, together with one among its two tiny moons.
Astronauts frequently react with awe after they see the curvature of the Earth under the Global Area Station. Now Mars scientists are getting a style of what that’s like, because of NASA’s 2001 Mars Odyssey orbiter, which finished its twenty second yr on the Purple Planet ultimate month.
The spacecraft captured a chain of panoramic photographs that showcased the curving Martian panorama under gauzy layers of clouds and mud. Stitched finish to finish, the ten photographs be offering no longer just a recent, and shocking, view of Mars, but in addition one that can lend a hand scientists achieve new insights into the Martian environment.
This odd view of the horizon of Mars was once captured via NASA’s Odyssey orbiter the use of its THEMIS digital camera, in an operation that took engineers 3 months to plot. It’s taken from about 250 miles above the Martian floor – about the similar altitude at which the Global Area Station orbits Earth. Credit score: NASA/JPL-Caltech/ASU
The spacecraft took the photographs in Might from an altitude of about 250 miles (400 kilometers) – the similar altitude at which the distance station flies above Earth.
“If there have been astronauts in orbit over Mars, that is the viewpoint they’d have,” stated Jonathon Hill of Arizona State College, operations lead for Odyssey’s digital camera, referred to as the Thermal Emission Imaging Gadget, or THEMIS. “No Mars spacecraft has ever had this sort of view earlier than.”
NASA’s Mars Odyssey orbiter captured the first-ever perspectives of Mars that show off the curving horizon and layers of environment, very similar to what an astronaut sees of Earth from the Global Area Station. Whilst there are not any astronauts but at Mars, this view offers us a way of what they could see. Laura Kerber, deputy challenge scientist for NASA’s Mars Odyssey orbiter, explains how and why the spacecraft captured a view of the Purple Planet very similar to the Global Area Station’s view of Earth.

How It Was once Finished
The explanation why the view is so unusual is on account of the demanding situations excited by developing it. Engineers at NASA’s Jet Propulsion Laboratory in Southern California, which manages the undertaking, and Lockheed Martin Area, which constructed Odyssey and co-leads daily operations, spent 3 months making plans the THEMIS observations. The infrared digital camera’s sensitivity to heat allows it to map ice, rock, sand, and mud, together with temperature adjustments, on the earth’s floor.
It may well additionally measure how a lot water ice or mud is within the environment, however most effective in a slender column immediately under the spacecraft. That’s as a result of THEMIS is mounted in position at the orbiter; it most often issues immediately down.
The undertaking sought after a extra expansive view of the ambience. Seeing the place the ones layers of water-ice clouds and mud are in the case of every different – whether or not there’s one layer or a number of stacked on most sensible of one another – is helping scientists enhance fashions of Mars’ environment.
“I bring to mind it as viewing a cross-section, a slice throughout the environment,” stated Jeffrey Plaut, Odyssey’s challenge scientist at JPL. “There’s a large number of element you’ll be able to’t see from above, which is how THEMIS usually makes those measurements.

As a result of THEMIS can’t pivot, adjusting the attitude of the digital camera calls for adjusting the placement of the entire spacecraft. On this case, the crew had to rotate the orbiter nearly 90 levels whilst ensuring the Solar would nonetheless shine at the spacecraft’s sun panels however no longer on delicate apparatus that might overheat. The very best orientation grew to become out to be one the place the orbiter’s antenna pointed clear of Earth. That intended the crew was once out of verbal exchange with Odyssey for a number of hours till the operation was once whole.
The Odyssey undertaking hopes to take identical photographs one day, shooting the Martian environment throughout a couple of seasons.
Over the Moon
To profit from their effort, the undertaking additionally captured imagery of Mars’ little moon Phobos. This marks the 7th time in 22 years that the orbiter has pointed THEMIS on the moon with a purpose to measure temperature diversifications throughout its floor.
“We were given a special attitude and lights prerequisites of Phobos than we’re used to,” Hill stated. “That makes it a novel a part of our Phobos dataset.”
The brand new imagery supplies perception into the composition and bodily homes of the moon. Additional learn about may just lend a hand settle a debate over whether or not Phobos, which measures about 16 miles (25 kilometers) throughout, is a captured asteroid or an historic bite of Mars that was once blasted off the skin via an have an effect on.

NASA is taking part with JAXA (Japan Aerospace Exploration Company) in a pattern go back undertaking to Phobos and its sister moon, Deimos, referred to as Mars Moon eXplorer, or MMX. Odyssey’s Phobos imagery will likely be useful to scientists running on each Odyssey in addition to MMX.

THEMIS was once constructed and is operated via Arizona State College in Tempe. JPL is a department of Caltech in Pasadena.
