Question 1

What is Celestia Dynamics?

Accepted Answer

Celestia Dynamics is a neutral, standards-based organization developing market mechanisms to address orbital debris through Space Debris Credits (SDC), Space Debris Exposure Rating (SDER), and the Equitable Space Access Fund (ESAF), creating economic incentives for debris removal and sustainable space operations.

Question 2

What are Space Debris Credits (SDC)?

Accepted Answer

Space Debris Credits (SDC) are tradable instruments representing verified debris removal from orbit. Each credit is backed by a Proof-of-Disposal certificate trackable on a public register, creating market incentives for active debris removal missions and turning orbital cleanup into an economically viable activity.

Question 3

What is Space Debris Exposure Rating (SDER)?

Accepted Answer

Space Debris Exposure Rating (SDER) is a transparent risk assessment system that quantifies debris exposure for orbital operations. It provides satellite owners, insurers, and operators with standardized metrics to evaluate collision risk, enabling safer mission planning and informed decision-making.

Question 4

What is the Equitable Space Access Fund (ESAF)?

Accepted Answer

The Equitable Space Access Fund (ESAF) channels resources to emerging countries with developing space programs, ensuring global and equitable access to orbital opportunities. ESAF supports capacity building, technology transfer, and participation in the sustainable space economy for nations without established space agencies.

Question 5

How does Proof-of-Disposal work?

Accepted Answer

Proof-of-Disposal is a verification certificate that documents debris removal events with timestamped evidence, orbital parameters, object identification, and removal method. Certificates are trackable on a public register and serve as the basis for issuing Space Debris Credits, ensuring transparency and accountability in debris removal operations.

Question 6

What is the Bonus-Malus system?

Accepted Answer

The Bonus-Malus system is an economic incentive structure that rewards operators for sustainable practices (bonus) and assigns costs to high-risk behaviors (malus). Operators with lower debris exposure ratings and responsible deorbiting receive financial benefits, while those creating excessive collision risk face higher costs, aligning economic incentives with orbital sustainability.

Question 7

How does Celestia Dynamics differ from government regulations?

Accepted Answer

Celestia Dynamics provides neutral, standards-based market mechanisms that work across different regulatory regimes. Unlike prescriptive government regulations, our systems create economic incentives that align profit with sustainability, allowing operators worldwide to participate regardless of their national jurisdiction while maintaining interoperability and transparency.

Question 8

Who can participate in Celestia Dynamics systems?

Accepted Answer

Satellite operators, launch providers, debris removal companies, insurers, policymakers, and space agencies from any nation can participate. Our pilot tracks in Europe, USA, Asia, and BRICS regions are actively onboarding participants. Contact us to join a pilot track or learn how your organization can integrate with our standards.
