Space Exploration as a Mirror of Earth's History 🚀

Published on February 26, 2026 | Translated from Spanish

Environmental historian Dagomar Degroot, in his book Ripples on the Cosmic Ocean, offers a distinct perspective on the exploration of the solar system. Far from being mere scientific curiosity, he argues that it has been a key factor in human history. The study of our planetary neighbors has shaped the understanding of terrestrial phenomena, from climate dynamics to the assessment of cosmic risks.

From Venus to Earth: Technology for Modeling Climates 🌍

One case that Degroot analyzes is Venus's runaway greenhouse effect. Space probe missions, such as the Soviet Venera or NASA's Magellan, provided critical data on the extreme conditions of that planet. This information was integrated into computational climate models developed in the second half of the 20th century. Thus, the technology to study alien atmospheres was refined and applied to simulate climate change scenarios on Earth, improving the accuracy of projections.

Our Neighbor Venus: The Best (and Worst) Example to Follow ☄️

It seems that, unwittingly, we have found in Venus the manual of what not to do. While here we debate emissions, our planetary brother has been proudly displaying for millennia the final result of an uncontrolled greenhouse effect. It's like having the neighbor who turned his house into a smoking dump: it doesn't inspire envy, but it instills a fear that helps keep ours a little more orderly. A cosmic lesson with nightmare nuances.
