Prelude to Apollo 17 Mission
Decoding the Genesis of Apollo 17: A Confluence of Ambitions and Discoveries
It’s an indelible imprint on the annals of human history – that iconic photograph of the last man standing on the moon, the Earth a lonesome sphere in the vast expanse of space. That man was Eugene Cernan, the Commander of Apollo 17, and his cohort on the lunar surface, Harrison Schmitt. The culmination of a series of intense scientific endeavours and human aspirations, this mission was the unique product of various integral catalysts and motivations.
The chief impetus behind the Apollo 17 mission was the Cold War rivalry between the United States and the Soviet Union. Thence emerged the compelling space race, with both nations vying for technological and ideological superiority. The U.S. had resolved, following the Apollo 11 moon landing in 1969, to maintain the momentum of their lunar exploits. This resolution was fortified by the favourable public opinion and support – an acceptance driven by national pride and the intoxication of human achievement in uncharted territories.
Simultaneously, continued lunar exploration would yield invaluable scientific data and expand our understanding of the universe. Specifically, the Apollo 17 mission aimed to collect samples from an unexplored region of the moon – Taurus-Littrow, renowned for its rich geological diversity. Lunar rock and soil from this area would provide significant insights into lunar volcanism, the potential presence of water ice, and the moon’s violent impact history.
Facilitating these scientific pursuits was the inclusion of Schmitt, a professional geologist, on the Apollo 17 crew. This was, in great part, a result of the scientific community’s advocacy and insistence for representation in lunar crews. Schmitt’s presence epitomized the growing recognition of the significant role of trained scientists in space missions.
Equally significant was the pressure mounted by budgetary constraints that plagued NASA by the early 1970s. As costs soared, political zeal for lunar exploration waned, and appropriations for the space agency dwindled. In effect, the pressing threat of the program’s truncation hastened the planning for Apollo 17, prompting it to be packed with multiple objectives and experiments.
Similarly, the escalating technicism in the space exploration domain was influential. Emerging technologies like the Lunar Roving Vehicle (LRV) allowed astronauts to cover larger surface areas and collect an unprecedented amount of lunar samples. The LRV was eponymous with the Apollo 17 mission – enabling the deeper and broader exploration that would comprehensively exploit its last moon visit.
Delving into the genesis of the Apollo 17 mission thus reveals a fascinating confluence of motivations – geopolitical rivalry, scientific curiosity, individual expertise, budgetary pragmatism, and technological advancements. Together, they sparked the execution of one of the most ambitious space missions of the 20th century, leaving a legacy that continues to inspire future explorations of the final frontier.

The Apollo 17 mission, launched in December 1972, remains the most recent mission to land humans on the lunar surface. This mission held numerous key objectives that were both innovative and imperative to the scientific community and aimed at furthering our understanding of the moon’s geography and history.
Primarily, the Apollo 17 mission, like its predecessors, sought to continue the assessment and investigation of the lunar surface’s environment. However, this mission marked a more specialized approach as it aimed to understand the geological context of the Taurus-Littrow landing site, an area rich in distinctive geology offering a unique and pivotal opportunity for in-depth study. The astronauts were tasked specifically with obtaining a diverse array of samples, such as lunar surface material and bedrock samples from the landing area, which was nestled on the edge of a deep valley ringed with high mountains and dark-colored volcanic material.
The second major objective was to deploy the Apollo Lunar Surface Experiments Package (ALSEP) – innovative equipment designed to gather data on seismic activity, lunar atmospheric pressure, and composition, among other environmental factors. These distributed experiments were of paramount importance to streamline scientific understanding of the lunar surface over a long period and offered an opportunity for continuous remote data collection even after the mission had ended.
An underlying objective, underscored by the inclusion of Harrison Schmitt, was to bridge the gap between terrestrial and lunar geology, creating a link to better understand our own planet’s geology. He was tasked with reading the moon’s “geologic story” inscribed within its rocks and mountains, thus humanizing an otherwise machine-dominated exploration.
Furthermore, Apollo 17 also aimed to demonstrate the feasibility of a scientist-astronaut in future space missions. The inclusion of Schmitt, a scientist, and not just a test pilot, incorporated a new dimension into the astronaut corps. It signified a transition from purely exploratory missions to missions with a strong emphasis on scientific research and findings.
Lasty, the Apollo 17 mission also held technological objectives. It aimed to further demonstrate the performance, capabilities, and reliability of the Lunar Roving Vehicle (LRV) in the challenging lunar environment as well as assess modifications placed upon it following its previous use in the Apollo 15 and 16 missions.
On a more abstract note, the Apollo 17 mission carried the torch of human curiosity and exploration, fostering an appreciation of the majestic human ingenuity. It stood as a testament to our relentless quest for understanding and symbolized humanity’s collective capacity to rise above the ordinary, stimulating global imagination and providing a distinct, first-hand, scientific perspective of our celestial neighbor.

Armed with the knowledge of a professional geologist, Schmitt provided detailed, on-the-spot analyses of the lunar surface and its various features. Documented through photographs and voice transmissions, these analyses created a priceless source of firsthand geological insights. The Lunar Roving Vehicle, a four-wheeled rover deployed on the Moon for the first time on Apollo 15 and subsequently utilised in Apollo 16 and 17 missions, aided in these comprehensive surveys by expanding the crew’s exploratory range.
The astronauts also played a significant role in expanding humanity’s comprehension of the lunar atmosphere—or lack thereof. Through a series of deployments and data collections using scientific instruments, profound insights into the extremely thin exosphere were derived. These results clinched critical debate points back on Earth regarding whether the lunar surface possessed an atmosphere—a unified acceptance of the vacuum-like conditions around the Moon was achieved.
The astronauts extended the fra mauro formation, a geological complex formed as a result of the giant impact that formed the Imbrium Basin, by analyzing the samples collected. This activity enabled them to outline the surface’s subsequent evolution and impact history, thereby advancing the broader understanding of the Moon’s geological chronology.
Deeper implications of this vast trove of geological and atmospheric information shed an illuminating light on hypotheses about lunar origins. The astronauts’ diligent sample collection enriched studies back on Earth, contributing significant evidence to the prevailing theory of the Moon’s formation, commonly known as the Giant Impact Hypothesis. This hypothesis suggests that the Moon was formed from the debris left over after an impact between Earth and a Mars-sized body.
Space exploration is a carefully measured risk, and operational testing under actual lunar conditions was an integral part of these missions. Every instrument deployed, from the LM to the ALSEP, played a crucial role in demonstrating the feasibility of different technologies under severe lunar conditions.
