In a matter of months, a NASA probe referred to as the Mars Reconnaissance Orbiter (MRO) will commence its 20th year surveying the Red Planet from orbit. And, akin to most 20-year-olds on Earth, MRO’s digital album is undoubtedly overflowing.

Per NASA’s details, MRO has just captured its 100,000th image of the Martian terrain utilizing its HiRISE camera. Stated differently, that calculates to about 5,000 images each year, 417 images each month, or roughly 14 each day since March of 2006.

The new landmark image, taken on Oct. 7, depicts a dim panorama of mesas, craters, and dunes recognized as Syrtis Major. This zone resides just southeast of Jezero Crater, the former lakebed where NASA’s Perseverance rover is exploring for indications of prior life, and manifests as an immense shadowy area when observed from a distance by astronomical observatories such as Hubble.

MRO has scrutinized this region on numerous previous occasions, and has previously uncovered evidence suggesting that the sand dunes there are gradually shifting across the planet’s surface.

“HiRISE has not merely unveiled how different the Martian topography is from Earth’s, it has additionally illustrated the ways in which that topography evolves across time,” Leslie Tamppari MRO’s deputy project scientist located at NASA’s Jet Propulsion Laboratory, expressed in an announcement. “We’ve noticed dune expanses advancing in tandem with wind currents and snowslides plummeting down precipitous inclines.”

The full view of Syrtis Major

Examining the shifting characteristics of the Red Planet over a duration will facilitate unraveling the mysteries of the governing influences and assist in determining whether it once hosted a flourishing water-based biosphere akin to Earth. Set aloft from Florida on Aug. 12, 2005, and positioned into Mars’ orbit on March 10, 2006, the MRO will prolong its undertaking to capture photographic records of the planet as long as it is capable.

Occasionally, MRO interrupts its main directive to peer outward into space. During October, the orbiter glanced skyward to capture a representation of the interstellar comet 3I/ATLAS as it swept approximately 19 million miles (30 million kilometers) away from the spacecraft – markedly nearer than the comet approached Earth at its closest proximity on Dec. 19.

While MRO was not engineered to monitor diminutive, rapidly traversing objects at such broadened distances, it still supplied initial substantiation that 3I/ATLAS presented the diagnostic traits of a genuine comet, encompassing a minute core enclosed within a luminous aura of gas and particulates.
