For a space elevator, the cost varies according to the design. Bradley C. Edwards received funding from NIAC from 2001 to 2003 to write a paper, [7] describing a space elevator design. In it he stated that: "The first space elevator would reduce lift costs immediately to $100 per pound" ($220/kg). [8] [9]
This equates to a price of US$2,350 per kg to LEO and US$5,620 per kg to GTO. In 2022, the published price for a reusable launch was $97 million. [ 98 ] In 2022 NASA contracted with SpaceX to launch the Nancy Grace Roman Space Telescope on a Falcon Heavy for approximately $255 million, including launch service and other mission related costs.
Space launch market competition is the manifestation of market forces in the launch service provider business. [1] In particular it is the trend of competitive dynamics among payload transport capabilities at diverse prices having a greater influence on launch purchasing than the traditional political considerations of country of manufacture or the national entity using, regulating or ...
2 is around 0.80 kg (1.8 lb) CO 2 per kg finished cement. Electrical power generation Varies with local power source. Typical electrical energy consumption is on the order of 90–150 kWh per tonne cement, equivalent to 0.09–0.15 kg (0.20–0.33 lb) CO 2 per kg finished cement if the electricity is coal-generated.
The variable density is normally described in kg per m 3, where regular concrete is 2400 kg/m 3. Variable density can be as low as 300 kg/m 3, [18] although at this density it would have no structural integrity at all and would function as a filler or insulation use only.
In 2010, the incremental cost per flight of the Space Shuttle was $409 million, or $14,186 per kilogram ($6,435 per pound) to low Earth orbit (LEO). In contrast, the comparable Proton launch vehicle cost was $141 million, or $6,721 per kilogram ($3,049 per pound) to LEO and the Soyuz 2.1 was $55 million, or $6,665 per kilogram ($3,023 per pound ...
