Our Martian heritage must be preserved, say leading scientists

Academics agree that by protecting robotic vehicles and landing sites we will help archaeologists of the future

Just as the outline of an iron-age hut or remains of a Roman sword cause excitement today, archaeologists of the future could be brushing Martian dust off metal and marvelling at one of Nasa's rovers.

Researchers have said that such instruments, as well as other forms of human activity on Mars, including landing sites and debris, must be preserved as part of the archaeological record of space exploration.
