Civil Municipal - Oct 2023

8 CIVIL AND MUNICIPAL VOLUME 4, ISSUE 10 The NPRM (PDF) lays out five upper stage disposal options including conducting a controlled reentry, moving it to a less congested storage or graveyard orbit, sending it on an Earth-escape orbit, retrieving it within five years and performing an uncontrolled atmospheric disposal or natural decay within 25 years. The FAA noted that the proposed rule would “align commercial space orbital debris mitigation practices with those accepted by the U.S. government for its space missions.” The rule will be open for public comment for 90 days following its publication in the Federal Register. According to the agency, current estimates put the number of orbital objects measuring 10 cm or greater at over 23,000 with projections for objects between 1 and 10 cm coming in at one-half million.
