Greg Smye-Rumsby - Mapping Worlds.
The first telescopes were relatively simple providing astronomers with views of the Moon and planets that were in effect upside down. This lead to maps with an orientation different to that of Earth. This changed in the early 1960s when space agencies around the world were looking to standardise mapping systems allowing future space missions and their observations to be placed into context.
But how were mapping programs carried out on other worlds such as Venus, Mars or the many moons of more distant worlds?
All welcome.
