In recent weeks the spotlight has moved from Mars to Venus. A major question in the search of life outside our own planet is if Venus was one day more earth-like.
In a new study scientists from Yale have formed a hypothesis based on pieces of Venus that have likely made it to the moon. During an era of a planetary bombardment of Earth’s twin sister, Venus as many as 10 billion rocks could have been blasted off-planet. Yale astronomer Samuel Cabot said, “Such catastrophic impacts such as these only happen every hundred million years or so — and occurred more frequently billions of years ago.”
Some of these rocks could of very likely made it all the way to the Moon. Gregory Laughlin, an astronomer from Yale, said, “There is a commensurability between the orbits of Venus and Earth that provides a ready route for rocks blasted off Venus to travel to Earth’s vicinity. The moon’s gravity then aids in sweeping up some of these Venusian arrivals.”
“An ancient fragment of Venus would contain a wealth of information. Venus’ history is closely tied to important topics in planetary science, including the past influx of asteroids and comets, atmospheric histories of the inner planets, and the abundance of liquid water.”
With the nearing Artemis deadlines for a moon landing in 2024 by American astronauts, it could very well be that we will be learning a lot more about Venus by going to the Moon.
