Lunar Expeditions: Unearthing or Erasing Life's Ancient Origins?
As humanity prepares for a return to the Moon through programs like Artemis, new research reveals a critical concern: the exhaust from spacecraft could contaminate ancient lunar ice, potentially destroying invaluable prebiotic organic molecules. These molecules, preserved in the Moon's polar craters for billions of years, are believed to hold the molecular blueprint for life's genesis on Earth. Scientists are now urging a careful balance between ambitious space exploration and the paramount need to safeguard these pristine cosmic archives, which offer an unparalleled window into our planet's earliest biological history.
