On June 2, 1896, Italian inventor Guglielmo Marconi submitted his application for a patent covering wireless telegraphy. His invention utilized radio waves to transmit Morse code over great distances without using wires. Marconi's work built on earlier experiments by Heinrich Hertz and Nikola Tesla. The patent, granted later that year, laid the legal foundation for modern radio broadcasting. He established the Wireless Telegraph & Signal Company to commercialize his technology. Marconi's wireless system revolutionized maritime communication and global news dissemination. This milestone marked the beginning of the age of wireless connectivity.

On June 2, 1910, British aviator Charles Rolls became the first man to make a non-stop double crossing of the English Channel by airplane. Flying in a Wright biplane, Rolls completed the out-and-back journey in under eight hours. This achievement followed his founding role in Rolls-Royce and passion for mechanical innovation. The flight demonstrated both pilot endurance and aircraft reliability at the dawn of powered flight. Thousands observed the daring attempt from coastal vantage points in England and France. Rolls' success helped inspire public confidence in aviation as a viable mode of transport. Tragically, he would lose his life in a flying accident later that year, cementing his legacy as a pioneering aviator.

As part of NASA's Surveyor program, Surveyor 1 touched down in Oceanus Procellarum on June 2, 1966. It transmitted over 11,000 images of the lunar surface and soil mechanics data to Earth. The successful soft landing demonstrated America's growing capabilities in the space race. The spacecraft's robotic arm scooped lunar soil, helping engineers understand the Moon's composition. Surveyor 1's achievements paved the way for the Apollo manned missions that followed. It remains a critical step toward human exploration of the lunar surface.

STS-91 launched from Kennedy Space Center aboard Space Shuttle Discovery as the ninth and final mission in the groundbreaking Shuttle-Mir series. The crew included both American and Russian astronauts who conducted joint scientific experiments and tested long-duration spaceflight operations. Discovery docked with Mir for a week, enabling crew exchanges and delivering new supplies and equipment to the station. The mission returned nearly 2,000 pounds of research samples and hardware for analysis on Earth. STS-91 helped solidify NASA’s partnership with Roscosmos and paved the way for the assembly of the International Space Station. The successful mission demonstrated key technologies and international collaboration that continue to shape human space exploration.

Mars Express launched aboard a Soyuz-FG rocket from Baikonur Cosmodrome, marking the European Space Agency’s inaugural mission to another planet. The orbiter carried a suite of scientific instruments designed to study Mars’ surface, atmosphere, and subsurface structure. Key objectives included mapping mineralogy, searching for water ice, and monitoring weather patterns. After a six-month cruise, Mars Express entered orbit in December 2003 and began transmitting high-resolution images. The mission discovered evidence of subsurface water ice at the Martian south pole and provided detailed data on the planet’s geology. Mars Express remains one of Europe’s most successful planetary missions, extending our understanding of Mars for over a decade.
