Grainy Moon photos were a ruse!

Those grainy Moon photos the public saw back in the early days of NASA's Moon missions were a ruse! No, not that ruse. Humans really went to the Moon. The ruse is that NASA actually captured much higher resolution images, but didn't disclose them publicly because they didn't want the Soviets to know how good…

Voyager 2 enters interstellar space and all I can think about are Klingons
