SpaceX fairing recovery program

The SpaceX fairing recovery program was an experimental program by SpaceX, begun in 2017 in an effort to economically recover and reuse expended launch vehicle payload fairings from suborbital space. The experimental program became an operational program as, by late 2020, the company was routinely recovering fairings from many flights, and by 2021 were successfully refurbishing and reflying previously flown fairings on the majority of their satellite launches.
