SpaceX Dismisses FAA Report on the Peril of Falling Space Debris

Introduction:

SpaceX has called on the Federal Aviation Administration (FAA) to correct a report claiming that falling debris from US-licensed satellite constellations could pose a risk to people on the ground. In a letter to the FAA and Congress, SpaceX engineer David Goldstein criticized the report, stating that it relied on flawed analysis and outdated studies. SpaceX’s Starlink constellation represents more than 85% of the expected risk, according to the report. However, Goldstein argued that SpaceX’s satellites are designed to fully demise during re-entry and that the company has a post-mission disposal success rate greater than 99%.

SpaceX Challenges FAA Report on Falling Debris Risks from Starlink Satellites

TAMPA, Fla. – In a letter to the Federal Aviation Administration (FAA) and Congress, SpaceX has called for a correction to a report that warns of potential risks from falling debris caused by its Starlink satellites. The report, published on the FAA’s website, suggests that by 2035, debris from U.S.-licensed satellite constellations in low Earth orbit (LEO) could harm or even kill someone every two years.

SpaceX Questions Flawed Analysis

The SpaceX principal engineer, David Goldstein, accused the FAA of relying on flawed analysis, stating that the report was based on assumptions, guesswork, and outdated studies. The company believes that the analysis used in the report is not applicable to its satellites, which are designed to fully demise during atmospheric reentry and have a post-mission disposal success rate greater than 99%.

FAA Report on Reentry Risks

The FAA’s report focuses on the rise of LEO constellations and the risks they pose to aviation and people on the ground. It stated that by 2035, 28,000 hazardous fragments from de-orbiting satellites and rockets could be surviving reentry each year. The report also highlighted that SpaceX’s Starlink satellites represent more than 85% of the expected risk in terms of falling debris.

The Complexities of Reentry Risks

Determining the exact risks associated with reentering satellites is challenging due to uncertainties and limited data. The report acknowledges that the available “ground truth” data is insufficient, making it difficult to accurately predict reentries and potential risks. The analysis aims to understand how behaviors can lead to reentry consequences and enable action to reduce these risks.

SpaceX Criticizes FAA’s Technical Competence

SpaceX has criticized both the FAA and the Aerospace Corp. for failing to update figures and consider various factors in their analysis. The company highlighted that the FAA accepted the report without questioning its accuracy, which raises concerns about the FAA’s technical competence in assessing and regulating in this area.

Risks from Rocket Debris

In addition to satellite reentries, the report also addresses the increasing risks posed by falling debris from rocket launches. The FAA points out that the upper stages of commercial rockets often have more mass than individual satellites and pose a greater reentry risk. The report highlights a Falcon 9 upper stage reentry in March 2021 and states that large space objects reenter the Earth’s atmosphere roughly once a week.

Overall, SpaceX challenges the FAA’s report on falling debris risks, asserting that their satellites are designed to fully demise during reentry. The company calls for a correction to the report and seeks a more accurate assessment of the risks associated with satellite constellations in LEO.

Summary: SpaceX Dismisses FAA Report on the Peril of Falling Space Debris

SpaceX has called on the Federal Aviation Administration (FAA) to amend a report warning that falling debris from US-licensed constellations in low Earth orbit (LEO) could cause injury or death every two years by 2035. The company’s principal engineer, David Goldstein, criticised the report as being based on flawed analysis, assumptions, guesswork, and outdated studies. The FAA’s report stated that 28,000 hazardous fragments from de-orbiting satellites and launching rockets could be surviving re-entry annually by 2035 if SpaceX’s rapid Starlink expansion plans go ahead.
