Michael Collins spent roughly 21 hours alone in the Apollo 11 command module while Armstrong and Aldrin were on the surface, and for 48 minutes of each orbit he was on the far side of the Moon with no radio contact to Earth, further from another human than anyone before him🔒 SSL Verified

"During the Apollo 11 mission, Michael Collins spent about 21 hours alone in lunar orbit aboard Columbia, losing radio contact with Earth for roughly 48 minutes of every orbit as he passed behind the far side of the Moon — a physical isolation no human has matched since."

"In November 1969, Apollo 12 astronauts retrieved the television camera from Surveyor 3 after 31 months on the lunar surface. When NASA opened it in Houston, technicians reported finding live Streptococcus mitis inside the foam — a claim later challenged, but one that reshaped how spacecraft are built."

"Singapore meets nearly 40 percent of its daily water demand with NEWater — sewage pushed through microfiltration, reverse osmosis, and UV disinfection at five plants run by PUB. Here's how a city-state of 5.9 million built the world's largest civilian closed-loop water system."

"South Korea's hills were stripped bare by 1953 after colonial logging and war. Seventy years later, forest cover stands at roughly 63 percent — one of the highest in the industrialised world — while the North remains largely denuded. The difference came down to a fuel switch, an authoritarian planting programme, and a border visible from orbit."
