The general suborbital rocket designs addressed in the PEIS include vehicles resembling conventional aircraft--30 to 140 feet long with unfueled weight of up to 9,921 pounds; vehicles resembling conventional rockets--6 to 33 feet long with unfueled weight of up to 5,500 pounds; and vehicles that hover—up to 20 feet in length or diameter with unfueled weight of up to 4,400 pounds. The FAA also assumes the total rocket fuel capacity of a reusable suborbital rocket not to exceed 11,00lbs.

The PEIS examines the potential environmental impacts of issuing an experimental permit for the operation of reusable suborbital rockets anywhere in the U.S. and abroad, and the potential site-specific impacts of permitted launches from seven FAA-licensed commercial launch sites: California Spaceport, California; Mojave Air and Space Port, California; Kodiak Launch Complex, Alaska; Mid-Atlantic Regional Spaceport, Virginia; and Space Florida.”

The FAA said it prepared the PEIS with cooperation from the National Aeronautics and Space Administration (NASA) and the US Air Force and said that its ruling does not propose site- specific environmental mitigation measures. “Rather, launch operators would be expected to implement site-specific mitigation measures that are consistent with those currently employed by the eight launch facilities addressed in the PEIS. Additional site-specific mitigation measures could be developed and presented in the site-specific documents that would tier from the PEIS.”

Reusable launch vehicles or rockets are one of the key technologies for the future of commercial space flight. The Review of United States Human Space Flight Plan Committee report said that commercial services to deliver crew to low-Earth orbit are within reach. “While this presents some risk, it could provide an earlier capability at lower initial and life-cycle costs than government could achieve. A new competition with adequate incentives to perform this service should be open to all US aerospace companies.”
