less than you would think, as you get further away from the earth, the shadow of 
the earth is smaller (think about a lunar eclipse, the shadow of the earth is 
barely the size of the moon, and the eclipse doesn't last very long)

Shuttle was ~50k/Kg
pre-spacex expendable rockets were ~$10k/kg
Falcon 9 has driven costs down into the ballpark of $1k/Kg (with indications 
that SpaceX internal costs may be significantly lower, but they price their 
launches at what the market will bear, under their competitors pricing)
Starship could get this down to under $10/Kg
