2.1 Chief, Safety and Mission Assurance (Chief, SMA)

2.1.1 The Chief, SMA, as stated in NPD 1000.3, is responsible for advising the Administrator and other senior officials on matters related to risk, safety, and mission success. As part of this responsibility, the Chief, SMA:

a. Establishes Agency policy, requirements, and guidelines to limit the generation of orbital debris from and safely dispose of NASA's spacecraft, payloads, and launch vehicle components consistent with national policy and international guidelines.

b. Collects, develops, promulgates, and advises on procedures, tools, models, methods, and data bases, including characterizations and forecasts of the orbital debris and meteoroid environments, to assess and mitigate the risk of orbital debris generation, disposal operations, and orbital debris and meteoroid impacts.

c. Reviews, monitors, and periodically reports to the Agency on compliance with requirements to limit the generation of orbital debris and safely dispose of spacecraft, payloads, and launch vehicle components by NASA programs and projects.

d. Adjudicates requests for relief to requirements in this NPR and NASA-STD-8719.14 on behalf of the Administrator or elevates such decisions to the Administrator.

e. Initiates, in coordination with the relevant offices, notifications of external Agencies concerning significant events and non-compliances.

f. Assists the Department of Defense and other U.S. Government departments and organizations on matters related to the characterization of the orbital debris environment and the application of orbital debris mitigation measures and policies for NASA space missions.

g. In coordination with OIIR, promotes the determination, adoption, and use of international orbital debris mitigation guidelines through international forums, such as the Inter-Agency Space Debris Coordination Committee (IADC) and the International Organization for Standardization (ISO).

2.1.2 The Chief, SMA established and maintains the NASA Orbital Debris Program Office and the NASA Meteoroid Environment Office to support the implementation of these responsibilities.

2.1.3 The NASA Orbital Debris Program Office (NASA ODPO):

a. Develops, maintains, and updates the orbital debris environment models and associated uncertainties to support the Chief, SMA, and programs and projects with the mitigation of orbital debris risk, and compliance with this NPR.

b. Conducts measurements of the orbital debris environment and conducts other research as needed to support the development of the orbital debris environment models.

c. Assists NASA mission project managers in technical orbital debris assessments by providing information and completing evaluations of the Orbital Debris Assessment Reports (ODARs) and End of Mission Plans (EOMPs) on behalf of the SMA Technical Authority.

d. Assists the Department of Defense and other U.S. Government departments and organizations on matters related to the characterization of the orbital debris environment and the application of orbital debris mitigation measures and policies.

e. Contributes to the determination, adoption, and use of international orbital debris mitigation guidelines through international forums such as the United Nations Committee on the Peaceful Uses of Outer Space, the IADC, and ISO.

2.1.4 The NASA Meteoroid Environment Office (NASA MEO):

a. Provides technical expertise and assistance to NASA mission project managers on behalf of the SMA Technical Authority.

b. Performs and supports research into improved techniques for determination of the meteoroid environment.

c. Develops, validates, and updates meteoroid models and databases (such as the Meteoroid Environment Model, MEM) and makes those software tools available to NASA programs and partners.

d. Collects meteoroid data and information internal and external to NASA for use in environment model improvement and validation and risk and anomaly investigations. The MEO facilitates the collection of this data through the appropriate agreements and distribute subsets upon request.

e. Forecasts meteor shower activity and disseminates these forecasts to U.S. Government spacecraft missions and operators via the MEO Web site or by direct email to interested parties. The MEO also provides, when feasible, custom meteor shower forecasts to programs upon request and provides assistance in assessing the risks posed by meteor showers.

f. Tracks meteor events and updates the U.S. Government and public on the circumstances surrounding these events.

2.2 Center-Level SMA Technical Authority

2.2.1 The Center-Level SMA Technical Authority, as defined in NPR 7120.5, oversees the implementation of requirements in this NPR and applicable standards and ensures the Chief, SMA is informed regarding potential concerns about non-compliances with these documents.

2.3 Mission Directorate Associate Administrator

2.3.1 The MDAA sponsoring the mission is responsible for limiting the risks to the public and space environment associated with NASA missions and NASA-provided hardware to accepted levels.

Note: Responsibilities for the Program Office are those that are delegated from the respective MDAAs.

2.3.2 Accordingly, the MDAA sponsoring the mission:

a. Ensures compliance with this NPR and NASA-STD-8719.14 as part of mission and project formulation and acquisition decisions.

b. Ensures requirements to limit the generation of orbital debris from and safely dispose of spacecraft, payloads, and launch vehicle components are included in relevant program or project documentation.

c. In coordination with the MDAA responsible for the launch service, requests relief from requirements for launch vehicle non-compliance(s) with orbital debris mitigation requirements.

d. Requests relief from requirements for spacecraft, payload, or hardware non-compliance(s) with orbital debris mitigation requirements.

2.4 NASA Project Manager

2.4.1 The Project Manager responsible for the mission, spacecraft, payloads, or hardware contributions to other spacecraft:

a. Ensures that the launch vehicle, spacecraft, payloads, or hardware contributions to other spacecraft comply with this NPR and NASA-STD-8719.14.

Note: Compliance for all secondary payloads (including small payloads such as CubeSats) is the responsibility of the secondary payload's Project Manager. The sponsoring MDAA is responsible for ensuring that the secondary payload's Project Manager is identified.

b. Provides documented evidence of compliance with orbital debris mitigation requirements and coordinates review and concurrence with the SMA Technical Authority for the Project.

c. Provides documented commands and passivation procedures to the spacecraft integration organization, (domestic or foreign partner responsible for spacecraft integration and operations), if applicable.

d. Evaluates the risk of orbital debris and meteoroid impacts to the project's mission objectives using appropriate environment models and failure criteria.

Note: Consult with the MEO and ODPO on the environment models.

e. Implements operational measures to limit the generation of orbital debris from and safely dispose of the spacecraft.

f. If the launch vehicle, spacecraft, payloads, or hardware contributions to other spacecraft are not, or not anticipated to be, in compliance with applicable orbital debris mitigation requirements, supports the MDAA responsible for the element in submittal of a waiver (relief from requirement), in coordination with the MDAA sponsoring the mission, if different.

g. Informs the Conjunction Assessment Risk Analysis (CARA) Team or NASA Human Space Flight Operations Directorate prior to execution of spacecraft maneuvers that will result in a change to their nominal mission orbit, allowing completion of analysis to prevent potential co-location or systematic conjunctions with debris or other on-orbit assets.
