Space is big, humans are small, and spacecraft, well, vary more in size than you might think. Redditor Heaney555 has compiled a chart, to scale, of every rocket, spacecraft, and space station involved in human spaceflight. Look at the enormity of the Saturn V rocket – it's as long as the International Space Station.
Designed to launch the Apollo missions, the Saturn V is still the biggest and most powerful rocket ever built. The sheer size of rockets, compared with the puniness of the actual vehicles they launch into space, give a sense of just how much energy is needed to escape Earth's gravity. Heaney555's chart is inspired by an earlier version by redditor firmada, and you can zoom into the full version below. [Heaney555]
