What are Launch Costs? (with pictures) - wiseGEEK

2020-12-8 · Launch costs refer to the cost of sending a payload from the ground to outer space, specifically low Earth orbit (LEO). Typical launch costs today are $10,000 US Dollars (USD) to $25,000 USD per kilogram ($4,500 to $11,000 USD per pound), though some countries subsidize space launches, occasionally reducing cost as low as $4,000 USD per kilogram ($1,800 USD per pound).
