Table 2.3. Effects of SPS Deployment3 aThe SPS impacts are for the total system and the U.S. totals are annual rates. Caution must be exercised in interpreting these data. ^Source: Ref. 2.8.3. Based on early version of SPS configuration (Scenario A). Does not reflect more recent designs. CSPS data from mining, processing, fabrication. U.S. total data for all sources from Ref. 2.8.6, 1973. ^From steel, aluminum, copper, cement processes. eSPS data from propellant manufacture, launch pad coating, construction.
