• OSMA Releases Significant NPR 8705.4A Updates

    NASA’s Office of Safety and Mission Assurance (OSMA) made significant updates to NPR 8705.4A, Risk Classification for NASA Payloads, effective April 29. 2021. OSMA updated the policy to reflect changes in risk acceptance and Technical Authority concurrence policies, to formalize and shorten the timeline for the risk classification process, to provide clearer and earlier documentation of the Safety and Mission Assurance (SMA) implementation approach, and (most importantly) better align stakeholder and implementer expectations.

Objectives Hierarchy

The Office of Safety and Mission Assurance (OSMA) has introduced a new objectives-based approach to better support NASA’s increasingly complex missions in a changing design environment. By focusing on objectives, OSMA hopes that the new standards will be more flexible, agile and cost-effective, and will allow more ingenuity to achieve objectives. It will serve as a guide to help programs and projects plan how they will meet their objectives, instead of dictating what they must do to via prescriptive requirements. Read the article, "OSMA Introduces New Objectives-Based Strategies," to learn more about objective hierarchies.

Post Mission

PMD

Post Mission Disposal (PMD) is a major component in debris mitigation. Orbital debris poses a risk to continued reliable use of space-based services and operations and to the safety of people and property in space and on Earth. Orbital debris mitigation measures have been developed to reduce the growth of the debris population. The key PMD element for Low-Earth Orbit satellites is the 25-year rule.
