When NASA’s Apollo 11 astronauts Neil Armstrong and Buzz Aldrin stepped on the moon in 1969 as the first humans, the length and extent of their extravehicular venture were mostly dictated by the extreme environmental conditions on the surface of the moon. Surface temperature at the area where they landed was 200 degrees Fahrenheit, one of the reasons for which they kept their foray limited to a short period.
Apart from the conspiracy claims disputing the validity of the moon landing, the astronauts’ testimony and scientific evidence present a gripping story of human determination and strength in the face of utmost adversity. Armstrong himself gave authoritative evidence to the challenges he and Aldrin encountered.
One of the main worries of the Apollo 11 planners was how well the astronauts’ high-tech, water-cooled space suits would work, as it had yet to be tested on the moon’s strange environment where standard air conditioning would not be sufficient. They had no idea what data to apply to calculate how long their little water bottle in their packs would keep their cool, and NASA bureaucrats restricted their surface working duration to 2 and 3/4 hours to avoid the onset of hyperthermia.
In addition, lunar surface conditions were another variable that was not known. The moon’s low gravity, being one-sixth the Earth’s, plus the vacuum and cold of space, made up an environment that could not be precisely duplicated on the planet. Armstrong said, “We were operating in a near perfect vacuum with the temperature well above 200 degrees Fahrenheit.”
Despite the hot and non-aerospace environment, the astronauts were also tasked with deploying experiments, sampling, and photography. Armstrong and Aldrin took these responsibilities with utmost commitment. The crew had to balance their scientific curiosity and the necessity of staying within the range of the TV camera as planners would like to observe their activities to learn for future space missions. Armstrong confessed to temporarily straying out of camera view to take pictures of potentially important bedrock features, indicating the astronauts’ eagerness to see as much as their means permitted.
Their haste was so great that after completion of the initial moonwalk, water remaining in the astronauts’ backpacks was measured to compare against estimates, providing useful data for future missions.
Armstrong equated the limited surface exploration of the moon to previous missions of our planet when he said, “Americans have visited and examined 6 locations on Luna, varying in size from a suburban lot to a small township. That leaves more than 14 million square miles yet to explore.” He did this for the purpose of stimulating additional exploration of the moon, noting the vast expanses of the moon that lie unmapped.
Despite the shortness of their stroll, the astronauts’ returns were staggering. The Lunar Laser Ranging Retroreflector, placed by Armstrong and Aldrin, still helps aid scientific experiments to this day. Later Apollo missions would benefit from the foundation laid by Apollo 11, venturing further using the Lunar Rover.
