You raise an interesting point. When Venus is on the side of the Sun opposite to Earth (in its superior conjunction), it is positioned closer to the Sun from our perspective. During this time, Venus is not visible from Earth because it gets lost in the Sun's glare.
However, Venus goes through phases similar to our Moon. When it is on the same side of the Sun as Earth, it is positioned further away from the Sun (its inferior conjunction). At this point, Venus can be observed in the early morning (before sunrise) as the "Morning Star" or in the evening (after sunset) as the "Evening Star."
Regarding the Moon landing, it's important to note that the Moon reflects sunlight, allowing it to be visible even during nighttime on Earth. The Moon is not entirely dependent on direct sunlight for visibility because it reflects light back to us.
During the Apollo Moon missions, NASA astronauts landed on the illuminated side of the Moon, where sunlight was present. They were able to navigate and perform their tasks using the sunlight, as well as their own artificial lighting sources when on the dark side of the Moon.
In summary, while Venus may not be visible during certain periods when it is closer to the Sun from our perspective, the Moon landing was possible because the Moon reflects sunlight and astronauts had access to artificial lighting sources during their missions.
