Beautiful chart depicting space exploration from 1959-2015 by Pop Chart Lab. From mental floss:
With all of NASA’s recent (and historical) explorations and achievements, it’s only natural that the visualization masters over at Pop Chart Lab would decide to make a poster dedicated to humankind’s expeditions into the final frontier. This stunningly detailed poster catalogs all of them—from Luna 2 in 1959 to DSCOVR in 2015. There are over 100 exploratory devices featured, from orbiters to rovers to landers. The color-coded poster traces the path each craft took on its trip through space, weaving a delightful web. Planets, moons, asteroids, and even Pluto appear as points of interest for the cosmic explorers.
