Date traditionally ascribed to Dom Perignon's invention of champagne; it is not clear whether he actually invented champagne, however he has been credited as an innovator who developed the techniques used to perfect sparkling wine.

Dom Perignon is traditionally hailed as the inventor of champagne, pioneering the sparkling wine method in 1693.
Dom Perignon, cellar master at the Abbey of Hautvillers, is long credited with perfecting the methode champenoise around 1693. He experimented with techniques to control secondary fermentation in the bottle, improving clarity and effervescence. His innovations in blending grapes and managing cork pressure laid the foundation for modern champagne production. Although historians debate his direct role, his name became synonymous with luxury sparkling wine. The methods he developed would spread throughout the Champagne region, fueling its global reputation. His legacy endures in every bottle that bears his name.

NASA's Phoenix spacecraft is launched.

NASA launches the Phoenix spacecraft to explore the Martian arctic in search of water and signs of life.
Phoenix was launched by NASA on 4 August 2007 aboard a Delta II rocket from Cape Canaveral, Florida. Tasked with landing near Mars’s north polar region, the spacecraft carried instruments to analyze soil chemistry and search for water ice. Its robotic arm dug trenches in the Martian regolith, delivering samples to onboard laboratories to detect organic compounds. The mission confirmed the presence of perchlorate salts and subsurface water ice, reshaping our understanding of Mars’s climate history. Phoenix operated successfully for over five months, sending back valuable data and images before concluding its mission in November 2008. Its achievements paved the way for future Mars landers and the ongoing search for past life on the Red Planet.
