The ISS weighs approximately 450 tons. What I was wondering is, what is the combined mass of all payloads we’ve put into orbit since the dawn of the space age? Is it more or less than the cargo capacity of a large container ship like the Emma Mærsk?
Sub-orbital payloads don’t count. I’m wondering about the total mass put into orbit and beyond in the case of space probes. For bonus credit, you could also tell me how much of it has fallen back to Earth due to orbital decay.
