NASA Launches Mariner 2 to Venus
NASA launched the Mariner 2 spacecraft to Venus to gather data about the planet's atmosphere and surface. This unmanned mission marked a significant milestone in space exploration as it was the first successful flyby of another planet. The spacecraft was designed to operate for over three months, collecting data for scientific analysis upon return to Earth. Mariner 2's successful journey provided valuable insights into Venus’s extreme temperatures and dense atmosphere, shaping future planetary exploration missions.

Venus passed in front of the star Regulus, allowing astronomers to study its geometry and atmosphere. Observations were made worldwide, focusing on measurements of the diameter of Venus as it occulted Regulus. This enabled scientists to gather critical data about Venusian atmospheric structure through precise timings and observations.

Clyde Tombaugh, an American astronomer, made a groundbreaking discovery while examining photographs taken in January. Working at the Lowell Observatory in Arizona, he was searching for a ninth planet beyond Neptune. His meticulous analysis of photographic plates ultimately led to the identification of a new celestial body, which would later be named Pluto, marking a significant milestone in astronomy.

George Mary Searle discovered the asteroid 55 Pandora, a significant celestial body, while working at the Washington observatory in the United States. This discovery added to the growing catalog of asteroids in the solar system and was part of the 19th-century scientific endeavors to explore the cosmos. Searle's identification contributed to our understanding of the size, shape, and composition of these minor planets.

Mathematical calculations revealed that the dwarf planet Pluto moved inside the orbit of Neptune for the last time before 1979. This movement demonstrated the unique orbital characteristics of Pluto, which has an elliptical orbit that periodically crosses that of Neptune, allowing for deeper insights into celestial mechanics and planetary dynamics.
