#apollo 11

• Aldrin — A surname of Germanic or Anglo-Saxon origin, famous due to the American astronaut Buzz Aldrin (b. 1930), the second man to walk on the Moon during the Apollo 11 mission. In the chemical industry and ecotoxicology, the lowercase term (aldrin) designates a highly toxic organochlorine insecticide, banned globally under the Stockholm Convention due to its heavy structural persistence in the environment.
• Moon landing — The act of moon-landing and its result; the complete aerospace operation of descent, structural contact, and securing of a cosmic vehicle on the crust of the Moon. This engineering phenomenon represents one of the most complex phases of a lunar mission, requiring real-time dynamic velocity and altitude corrections.
• Armstrong — A proper surname of Anglo-Saxon origin borne by prominent historical figures, most notably Neil Alden Armstrong (1930–2012), the American astronaut who became the first person to walk on the Moon during the Apollo 11 mission in July 1969. Etymologically, it literally translates to 'strong arm'.
