Our Martian heritage must be preserved, say leading scientists
Briefly

Researchers emphasize that instruments like NASA's rovers and landing sites must be preserved as part of the archaeological record of space exploration.
Dr. Holcomb states that future excavation of Martian human activity is akin to discovering iron-age artifacts, establishing our early steps into the solar system.
The team warns that the effects of natural weathering and impacts pose a risk to space heritage, and once lost, such materials cannot be replaced.
Holcomb compares current human activity on Mars to past migrations and stresses that preserving these artifacts is essential for recording our species' history.
