The rotational reorientation of the Moon, a phenomenon that has left its mark on the Moon’s geological configuration, has been studied in light of the large impacts that occurred on its surface during its early evolution. This work investigates the possibility that a single impact from a massive object, similar to those described on other celestial bodies in the solar system, may have caused a significant redistribution of lunar mass at an early stage in its history. This redistribution would have led to and promoted its rotational reorientation and its current state of tidal locking with Earth. Such an event would not only have altered the Moon’s rotational orientation but also affected the distribution of craters and tectonic structures on its surface

This paper analyzes the challenges and achievements in the creation of digital visual effects in the movie Tron (1982). The film was a pioneer in the extensive use of digital imagery directly integrated into its footage, which required groundbreaking collaboration among several specialized companies and a significant budget (a working method that complex visual effects-heavy films routinely employ today). The text explores the evolution of technology and methods used in the production of that pioneering film, stemming from one of the film studios that had long been engaged in research and development, Disney, throughout its history. It also delves into the logistical and technical challenges faced by the visual effects teams. The significance of this film in the history of visual effects in cinema is emphasized, as well as its influence on subsequent generations of filmmakers and digital artists.
