d. Concordes consume 9 to 16 tons of fuel per hour and emit 13 to 15 pounds of NO per 1000 pounds of fuel. e. Based on 10% of booster exhaust weight for upper bound calculation. Other Booster Emissions. The effects on the environment caused by all of the components of the Shuttle booster exnaust are being evaluated by NASA. Studies of HC1 reactions affecting ozone concentrations in the stratosphere and acidity of rain in the troposphere are in process. The characteristics of the A12O3 particulates are being established to allow prediction of stratospheric accumulation effects, their participation in heterogeneous chemical reactions, and their seeding effects in low clouds. The program also includes measurements of effects caused by current launch vehicles using solid boosters. The best estimates at this time are that none of these potential problems will be insurmountable, even at the launch rates necessary for the Satellite Solar Power Station program.
