What is the credibility of this depiction of the Mariner-1 disaster in 1962, given the abundance of historical photos and footage it includes?

The Mariner-1 disaster is a well-documented event in space history. The Mariner-1 spacecraft, an early probe intended for a flyby of Venus, failed shortly after launch due to a guidance system error on July 22, 1962. Various analyses and accounts have been made about this incident, so evaluating an account’s accuracy can involve a few […]

How might life have endured on Mars considering its climatic shifts from hot to cold and back to hot again?

Mars has experienced significant climatic changes over its geological history, which profoundly affects its potential to support life. Initially, during its early history approximately 3.8 billion years ago, Mars likely had a thicker atmosphere, which could have supported warmer, wetter conditions similar to those of early Earth. This period, known as the Noachian, might have […]

Could the moon still be geologically active? Recent findings suggest it might be.

The notion that the Moon is geologically dead has been challenged by new evidence suggesting continued dynamism beneath its surface. Traditionally, the Moon was considered a relic of the solar system’s past, with all volcanic and tectonic activities ceasing billions of years ago. However, several lines of evidence indicate ongoing geological processes. Firstly, the presence […]
