ORDEM 3.2
ORDEM 3.2 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
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.
DAS 3.2
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.
Quarterly News
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) is a Delegated Program in the Office of Safety and Mission Assurance (OSMA) at NASA HQ. The 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.
