ORDEM 3.1 is for engineering solutions requiring knowledge and estimates of the orbital debris environment. It can also be used as a benchmark for ground-based debris measurements and observations.
LEGEND is a full-scale, three-dimensional, debris evolutionary model that is the primary foundation to the ODPO's study of the long-term debris environment projection and how it will evolve over time.
The Debris Assessment Software utility will be periodically updated by NASA to reflect the latest understanding of the man-made debris environment in Earth orbit.
The ODQN publishes some of the latest advancements in orbital debris research, offers news and statistics, presents project reviews and meeting reports, and details about upcoming events.
The NASA Orbital Debris Program Office (ODPO) has taken the international lead in conducting measurements of the orbital environment and in developing the technical consensus for adopting mitigation measures to protect the users within it. Located at the Johnson Space Center, the Office continues to develop an improved understanding of the orbital debris environment and measures that can be taken to control debris growth.
