Each rock and soil sample is a testament to the geological processes that transpired over millions of years on this extraterrestrial celestial body.
One of the enormous revelations from the analysis of lunar samples was the confirmation of the Giant Impact Hypothesis or the Theia Impact. This suggests that the Moon originated from the violent, cosmic collision of a Mars-sized body, dubbed Theia, with Earth approximately 4.5 billion years ago. Two key lunar samples – a basaltic rock and an anorthosite rock – extend corroborative evidence towards this theory. The basaltic rock is a testament of volcanic activity on the moon, while the anorthosite is indicative of a primordial crust. Together, they narrate an ancient tale of planetary conflict, fire, and reforming.
Another striking find in the samples was the tiny orange glass beads, popularly known as the ‘orange soil’- a crucial piece of evidence highlighting the moon’s active volcanic history. The presence of volatile elements in the orange soil twisted previous beliefs about the Moon’s inherent dryness and pointed towards the existence of internal lunar water. The volatile element, specifically Titanium, suggests that the lunar mantle, contrary to prior beliefs, might not be homogenous but complex and diverse.
Schmitt’s extensive geological observations on the lunar surface led to the realization that the moon had been geologically active in the past, heralding a significant shift in our understanding of our celestial neighbor. For instance, the repeated references to ‘boulders’ across his transects were indicative of the moon’s past seismic activity. Moreover, his observation of the lunar regolith’s composition and texture has provided a richer understanding of space weathering processes.
As serious strides were taken by the astronaut-geologist during surface excursions using the Lunar Roving Vehicle (LRV), high resolution, close-up images of the moon’s surface could be obtained.
