Headline: Preserving Mars’ Historical Treasures: Anthropologists Urge NASA to Catalog and Protect Artifacts on the Red Planet
Subheading: From astronauts’ lunar leftovers to Mars mission remnants, space debris gains new appreciation as invaluable historical records.
MARS, the red planet some 140 million miles away from Earth, has witnessed humanity’s presence through various exploration missions. Since 1971, when the Soviet Union’s Mars 2 craft left behind debris, a parachute, and rover tracks, humankind’s footprint has grown increasingly visible on the Martian surface.
Now, a group of anthropologists led by Justin Holcomb from the University of Kansas is calling on NASA and other space agencies to document and safeguard artifacts left behind on Mars. Their concern? The planet’s harsh environment could bury or destroy these historical objects.
Holcomb advocates for an international registry, similar to that used by the United Nations, to track and protect these objects. "These aren’t just space trash; they’re significant heritage. The solution for trash is disposal, but for heritage, it’s preservation," Holcomb asserts.
The term "space debris" often refers to orbiting junk that poses risks to satellites and astronauts aboard the International Space Station (ISS). While larger objects are tracked—around 27,000 pieces larger than four inches are currently monitored by the U.S. Department of Defense—the abundance of smaller, untracked items, such as bolts or screws, poses serious threats due to their high speeds, up to 15,700 mph.
Ironically, the idea of viewing space debris as historical artifacts is not new. In 2012, NASA released an inventory of roughly 800 items left on the Moon, including dirt, tools, cameras, and even a golf ball. Rather than seeing these items as clutter, they are regarded as crucial historical records.
Now, with more nations engaging in space exploration, new missions leave behind additional artifacts on both the Moon and Mars. However, while lunar items face less severe environmental threats, Mars’ extreme conditions demand heightened attention from geoarchaeologists, who study how the Red Planet’s harsh conditions might affect these objects over time.
Mars’ notorious dust storms, like those seen by the Mars Reconnaissance Orbiter around a decade ago, could churn up terrain and bury items. Wandering sand dunes pose another threat to the preservation of Mars’ historical record.
While no unified inventory plan exists yet for Mars, each mission team keeps tabs on their own equipment. Combining these lists would create a comprehensive catalog—a task that’s overdue, given the escalating number of missions and artifacts strewn across the Martian landscape.
