This question asks how much mass has been launched into Space. I would like to know how much mass was required to launch that mass into Space. What is the ratio between mass launched and the resources required to make the worlds (successfull & unsuccessfull) launches since Sputnik?
If we assume around 4000 total launches, and make the wildly inaccurate assumption that the average is 3000Tons (Saturn V plus maximum LEO payload)... 12 million tons. (Actual is less).
Earth Mass 5.972E21Tons.
12E6 tons versus just shy of 6E21 =0.5E15=5E14
So under 1/4.976E14 or 2 quadrillionths. Given the stupidly high assumption of mass launched, and the ignoring the returned to planet mass, easily less than 1 quadrillionth has actually remained in space.
