🔬 March 18, 1965 – First Spacewalk (EVA) Conducted by Alexei Leonov On this day in 1965, Soviet cosmonaut Alexei Leonov became the first human to conduct a spacewalk, an event that revolutionized space exploration and technology. Leonov exited his Voskhod 2 spacecraft, tethered by a 16-foot cord, and floated in the vacuum of space for 12 minutes. However, his spacesuit ballooned due to the lack of atmospheric pressure, making reentry into the capsule difficult—forcing him to manually vent air to fit back inside. This historic feat paved the way for modern extravehicular activity (EVA), crucial for satellite repairs, space station construction, and future missions beyond Earth’s orbit. It also influenced the development of advanced spacesuit technology and life-support systems, key innovations still evolving today. 💡 How It Changed the World - Led to further development of spacewalking suits and safety protocols. - Helped advance the design of spacecraft with airlocks for EVA missions. - Set the stage for the Apollo Moon missions and the International Space Station (ISS). Would you take a spacewalk if given the chance? 🌌 Let us know in the comments! 🚀✨ #InventorHistory #OnThisDay #SpaceTech
