July 10 has witnessed groundbreaking developments in science and technology. This remarkable day features both revolutionary discoveries and the brilliant scientists who shaped human history. Interestingly, the 2025 Buck Moon (Full Moon) also falls on this very day.
Here are some key scientific milestones from July 10 in history:
📡 1921 – First Successful Transatlantic Radio Broadcast
On July 10, 1921, the first successful transatlantic radio transmission was completed. This technological achievement marked the beginning of a new era in global communication.
🧬 1925 – The Scopes “Monkey” Trial Begins
The Scopes Trial, which began on July 10, 1925, saw American teacher John Scopes on trial for teaching evolution in school. The trial became a symbol of the clash between science and religion in public education.
🛰️ 1962 – First Active Communications Satellite: Telstar Launched
On July 10, 1962, Telstar 1 was launched into orbit. It enabled the first transatlantic satellite TV broadcast, ushering in a new age of global media and telecommunications.
🌕 1969 – Final Preparations for Apollo 11 Moon Landing
By July 10, 1969, NASA was making final preparations for the Apollo 11 mission. Just six days later, on July 16, the spacecraft would launch, and by July 20, Neil Armstrong and Buzz Aldrin would walk on the Moon.
🌊 1985 – Greenpeace Ship “Rainbow Warrior” Sunk
On July 10, 1985, the Rainbow Warrior, a Greenpeace ship, was sabotaged and sunk by French intelligence agents in Auckland Harbor, New Zealand. The incident became a global symbol of environmental activism.
🧬 1997 – Neanderthal DNA Supports “Out of Africa” Theory
Scientists in London announced DNA findings from Neanderthal remains on July 10, 1997. The study supported the “Out of Africa” theory of human evolution and revealed genetic links between Homo sapiens and Neanderthals — a turning point in paleogenetics.
🌿 2018 – Rising CO₂ and Its Effect on Crops & Milk Production
On July 10, 2018, University of Michigan researchers reported that increased atmospheric CO₂ levels caused biochemical changes in forage crops vital for milk production. The study shed light on the impact of climate change on agriculture and food security.
🧠 2019 – Discovery of Ancient Homo sapiens in Greece
A 210,000-year-old Homo sapiens skull found in Apidima Cave, Greece, was revealed on July 10, 2019. It suggested that modern humans lived in Europe much earlier than previously thought, reshaping the map of human evolution.
🌕 2025 Buck Moon and Its Scientific Relevance
The 2025 Buck Moon (Full Moon) will occur on July 10 at 10:37 PM CEST / 4:37 PM EDT / 1:37 PM PDT in the sign of Capricorn. It holds significance for astronomers and science enthusiasts alike.
The name “Buck Moon” comes from the Algonquin tribe of North America, referring to the time when male deer grow new antlers. According to NASA, this may be a regular full moon astronomically, but its proximity to the anniversary of the Apollo 11 Moon landing gives it special symbolic value.
