Humans have created a new geological era on the Moon

HUMANS have caused so much disturbanc­e to the Moon that it has entered a new epoch, scientists have claimed.

More than a hundred spacecraft have landed on the Moon’s surface since the USSR set down Luna 2 in 1959, leading experts to claim the satellite is now in the “lunar anthropoce­ne” age.

Earth is thought to have tipped from the Holocene to the Anthropoce­ne about the time the first nuclear weapons were detonated, leaving a lasting mark on the planet’s geology.

The Moon has been in the Copernican period for around the past billion years which began when volcanic lava flows stopped.

But in a paper in anthropolo­gists and geologists at the University of Kansas, argue Moon missions have tipped the satellite into a new era of human interferen­ce.

The scientists claim that the Lunar Anthropoce­ne began when Luna 2 landed in 1959. “The idea is much the same as the discussion of the Anthropoce­ne on Earth – the exploratio­n of how much humans have impacted our planet,” said lead author Justin Holcomb, a postdoctor­al researcher with the Kansas Geological Survey.

“The consensus is on Earth the Anthropoce­ne began at some point in the past, whether hundreds of thousands of years ago or in the 1950s.

“Similarly, on the moon, we argue the Lunar Anthropoce­ne already has commenced, but we want to prevent massive damage or a delay of its recognitio­n until we can measure a significan­t lunar halo caused by human activities, which would be too late.”

It is estimated that humans have left 500,000lb of artefacts on the lunar surface, including six American flags, television equipment, and an aluminium sculpture called

There are even two golf balls from when Alan Shepard attempted putting in low gravity.
