Can Current Earth-Based Telescopes See Astronauts on the Moon?

The idea of using Earth-based telescopes to observe astronauts walking on the Moon has intrigued many. However, the technical challenges are immense, and the current capabilities of Earth-based telescopes fall far short of what would be required.

Why Earth-Based Telescopes Fall Short

The primary obstacle is the vast distance between Earth and the Moon, which is approximately 240,000 miles (384,400 km). Even with the most powerful Earth-based telescopes, the minuscule size of the Moon makes detailed observation challenging. A simple calculation reveals the magnitude of the problem:

Calculate the fraction of the Earth-Moon distance that 6 feet (1.8 meters) represents. Estimate the magnification required to resolve such a small feature. Account for atmospheric distortion, which can further limit the clarity of the images.

No existing Earth-based telescope can show anything smaller than 4000 feet across on the Moon. To put this into perspective, even the largest optically corrected telescopes on Earth have apertures around 10 meters, which falls far short of what would be needed, with the theoretical requirement being a 100-meter aperture telescope to resolve surface features with reasonable clarity.

Key Considerations on Telescope Resolution

The resolution of a telescope is determined by the diameter of its aperture. The larger the aperture, the better the resolving power. For instance, to resolve a surface feature on the Moon, such as the Apollo landing site, with a rough estimate using the moon's distance of about 385,000 km and a feature size of 10 meters, one needs a telescope with a diameter of approximately 100 meters.

Technological Challenges of Moon Missions

Even without the need for such an enormous telescope, going to the Moon itself poses significant technological hurdles. The energy requirements for both ascent and descent, as well as maintaining a human environment, are immense and current technologies fall short. Here are a few key challenges:

The fuel necessary to blast off from the Moon and into lunar orbit is too heavy to carry, exacerbating the launch mass issues. Soft landings require sufficient fuel, which adds to the weight issue and the complexity of the mission. Rapid changes in temperature from the intense sunlight to the deep darkness of lunar shadows pose a significant threat to human survival without bulky and heavy life support systems.

Given these constraints, current technology is insufficient to support a moon mission. While future advancements in technology, such as nuclear-powered systems or alternative energy technologies, may eventually provide a feasible solution, current mission concepts remain in the realm of science fiction.

Official Apollo Claims and Skepticism

Fraction of genuine belief in the Apollo moon missions has been growing skepticism. Doubts have been fueled by several alleged losses of crucial evidence:

Designs for the Lunar Module are claimed to be lost. Original video footage from the alleged moonwalks is missing. Telemetry data from the alleged Apollo missions is not available.

These allegations suggest a level of secrecy and potential credibility issues. If one is to accept the official Apollo narrative, one must also believe in the existence of a magical space suit, invisible rocket fuel, and a gigantic telescope capable of watching astronauts from Earth. Many argue that such claims are highly unlikely and more likely part of a conspiracy theory rather than historical fact.

In conclusion, while the idea of watching astronauts on the Moon from Earth is fascinating, the current state of technology does not support such an observation. The challenges in both telescope resolution and the practical execution of a moon mission highlight the immense gap that still exists in our technological capabilities.
