Using his self-built 24-inch telescope in Malta, William Lassell spots Umbriel and Ariel, two previously unknown satellites of Uranus. This discovery expands our understanding of the outer solar system and demonstrates the capabilities of mid-19th century telescopic technology. Lassell’s methodical observations laid groundwork for future planetary studies. The naming of the moons after Shakespearean characters adds a cultural touch to the scientific achievement. The dual discovery highlights the era’s rapidly advancing astronomical research.

On October 24, 1911, aviation pioneer Orville Wright achieved a remarkable glider flight of nine minutes and 45 seconds at Kill Devil Hills, North Carolina. This achievement demonstrated the Wrights’ deep understanding of aerodynamics and control surfaces. The flight helped validate gliding principles that would influence future aircraft design. Orville meticulously adjusted wing angles and used warp controls to maintain stable flight. His long-duration glide captured the attention of engineers and the public alike, signaling a new era in aviation exploration. The experiment laid groundwork for continuous improvements in powered and unpowered flight technology.

Developed from captured German technology, the V-2 No. 13 rocket was launched from White Sands Missile Range. On October 24, 1946, a camera mounted on its nose reached an altitude of 65 miles (104 km) above Earth. The image produced was the first-ever photograph taken from outer space, revealing Earth's curvature. This milestone demonstrated the potential of rocketry for space exploration and scientific research. The experiment paved the way for future space photography and satellite imaging.

On October 24, 1957, the United States Air Force launched Project Dyna-Soar (Dynamic Soarer), its first crewed spaceplane initiative. The program aimed to build a hypersonic glider capable of reconnaissance, bombing, and rescue missions from orbit. Engineers explored advanced materials and aerodynamic designs to endure reentry. Despite extensive research and several design revisions, the project faced technical challenges and budget overruns. The Dyna-Soar program was eventually cancelled in 1963, but its innovations influenced later spacecraft development.

On October 24, 1998, NASA launched Deep Space 1 aboard a Delta II rocket from Cape Canaveral. It was the first mission under the New Millennium Program, designed to validate innovative spacecraft systems. Key technologies included ion propulsion, autonomous navigation, and advanced remote sensing instruments. Deep Space 1 conducted a successful flyby of asteroid 9969 Braille in 1999, capturing valuable images. It went on to fly by Comet Borrelly in 2001, providing detailed cometary data. The mission demonstrated the reliability of its experimental systems and paved the way for future deep-space probes. Its achievements influenced the development of subsequent NASA missions such as Dawn and New Horizons.

On October 24, 2007, the Chang'e 1 spacecraft lifted off from Xichang Satellite Launch Center aboard a Long March 3A rocket. It became China’s inaugural mission under the Lunar Exploration Program. The orbiter carried instruments for lunar surface imaging and topographical mapping. Chang'e 1 successfully entered lunar orbit in November 2007 after a week-long transit. It mapped the Moon’s surface, providing valuable data on composition and terrain. The mission lasted 16 months, concluding with a controlled impact on the lunar surface in March 2009. Its success laid the groundwork for subsequent Chinese lunar missions, including Chang'e 5.

On October 24, 2014, Chang'e 5-T1 lifted off to execute a circumlunar trajectory and return to Earth. The mission aimed to validate re-entry and precision landing technologies for China’s planned Chang'e 5 sample-return probe. It performed a flyby behind the Moon before heading back, testing deep-space communication systems. After 7 days in space, the spacecraft re-entered Earth’s atmosphere, landing safely in Inner Mongolia. The successful mission demonstrated China’s growing capabilities in spacecraft navigation and control. Data collected informed the design and planning of the subsequent Chang'e 5 mission. Chang'e 5 later achieved the nation’s first lunar sample return in 2020, benefiting from these tests.
