In this DataVerse we publish datasets related to the ASTRIAGraph project. ASTRIAGraph is a framework that enables monitoring, assessment, and verification of space-actor-behavior in the context of legal and policy instruments. The goal of ASTRIAGraph is to achieve space safety, security, and sustainability. It supports Anthropogenic Space Objects (ASOs) visualization and tracking, as well as space traffic management queries through a publicly-accessible web platform.

ASTRIAGraph is supported by a NEO4J graph database where multiple private and public data sources of space domain information are automatically ingested, curated, organized, integrated, and analyzed to solve scientific inquiries relevant to Space Domain Awareness (SDA). Data organization is based on a data model designed in relation to scientific case studies contributed by the community of researchers, policy makers, and the public interested in SDA. Amongst the scientific case studies supported by ASTRIAGraph are: orbital determination of ASO's, identification of GEO satellite disposal in compliance with international regulations, and compliance with registration requirements of the United Nations (UN) Office for Outer Space Affairs.

Led by Dr. Moriba Jah (, the interdisciplinary research team is formed by faculty, researchers, and students from the Department of Aerospace Engineering and Engineering Mechanics ( and from the Texas Advanced Computing Center ( at the University of Texas at Austin.

Feuge-Miller, Benjamin; Kucharski, Daniel; Jah, Moriba, 2021, "ASTRIANet Data for: Cosmos-1408",, Texas Data Repository, V2
Overview This dataset contains observations along the expected track of the COSMOS-1408 satellite on Nov. 16, 2021. Objects are observed which have low relative angular velocity with respect to the expected pre-breakup track, possibly having originated from the COSMOS-1408 breaku...

Nair, Vishnu, 2021, "Statistical Families of the Trackable Earth-Orbiting Anthropogenic Space Object Population in Their Specific Orbital Angular Moment Space",, Texas Data Repository, V2
Motivation Our motivation for this analysis is to create an efficient and transparent system to categorize anthropogenic space objects (ASO's) based on orbital behavior, namely angular momentum. Doing so, we hope to lay the groundwork for future studies that involve trackability,...
