This iBook introduces participants to orbital debris environment characterization and mitigation, including characterization and future growth of the orbital debris environment; collision risks; and orbital debris mitigation policies, processes, requirements, and standards.

This iBook is designed for NASA project practitioners, mission members, engineers, scientists, and other project support staff who are involved in spacecraft design and operations and interested in orbital debris issues and employing mitigation approaches, including “design for demise.”

Upon completion of this course, participants will be able to:

  • Identify the characteristics of the orbital debris environment and its sources.
  • Describe various measurements in low-Earth orbit (LEO), medium-Earth orbit MEO, and geosynchronous orbit (GEO); explain orbital debris modeling methods; and explain collision risk probabilities and assessments.
  • Describe orbital debris mitigation policies at the agency, national, and international levels.
  • Explain the nature of NASA’s Human Casualty Reentry Risk Assessments and Criterion.
  • Describe the NASA Reentry Risk Evaluation Process, per NASA Standard 8719.14 requirements.
  • Explain the benefits of DAS and ORSAT reentry assessment tools.
  • Define the objectives for “design for demise” philosophy.
  • Identify implementation design for demise strategies on specific NASA missions, including GPM, GLAST, RBSP, and Commercial Orbital Transportation Services (COTS).
