The Australian continent has the highest solar radiation per square metre of any continent in the world. That’s 10,000 times LARGER than our energy consumption!
69 hours, 8 minutes and 16 seconds after launch, the crew reached the far side of the Moon. They burned their engines for a lunar orbit insertion (LOI), which lasted four minutes. The burn slowed the spacecraft down so it could be captured by the Moon’s gravitational pull, making it the first ever manned satellite of another world.
The Moon is tidally locked to Earth, which means it rotates on its axis at the exact same rate that it orbits Earth. As a result, we only see one side of the Moon from Earth’s surface. Borman, Lovell and Anders were the first to see the far side…
Lovell described it during a live telecast as,
“essentially gray, no color…like Plaster of Paris or some sort of grayish beach sand.”

Just 5% of the world lives in the entire blue area. Another 5% lives in the red area.
Good to see discussion of Gall-Peters v Mercator. I sit with Gall-Peters when a globe is not available!. [Am pretty sure the GTAV were one of the first to introduce this in the 80’s… had one in my classroom in 1987!]
