Commercial Space Vehicle Emissions Modeling 82 A database of emissions indices was compiled for the first-stage rocket engines of current and indevelopment commercial space vehicles, including every orbital-class rocket that was built or launched in the United States in 2019. The primary emissions indices are stored in the internal fleet database, and the final emissions indices are calculated within the commercial space vehicle emissions model using the first-order estimates.

Commercial Space Vehicle Emissions Modeling 83 The existing AEDT user interface will accommodate most of the inputs for the commercial space vehicle emissions model without modifications. Relatively minor modifications will be required to enable users to add spaceports, select space vehicles from the fleet database, and specify detailed spacecraft trajectory data.

Commercial Space Vehicle Emissions Modeling 86 formed due to afterburning in the extremely high-temperature Falcon 9 exhaust plume than in the lower-temperature exhaust of the Boeing 737-800. The results shown in Figure 43 demonstrate one useful application of the commercial space vehicle emissions model.
