Introduction

Aerie is an open source, extensible software system for planning, scheduling, and commanding space missions. Developed and maintained by NASA's Advanced Multi-Mission Operation System (AMMOS), it provides modeling and simulation capabilities that can be used for mission planning and analysis during project formulation all the way through operations, where it can be used to manage and validate spacecraft activity plans. Aerie is actively being used on flagship missions like Europa Clipper, but is equally suitable for smaller missions and constellations.

Some of the main features of Aerie include:

  • A library to write mission models in the Java programming language
  • A highly performant discrete-event simulator
  • An embedded domain specific language (EDSL) for defining and executing goal-based scheduling rules
  • An EDSL for defining and executing activity and resource constraints
  • An EDSL for defining and executing activity command expansions
  • An EDSL for defining sequences, and a fully-featured browser-based sequence editor
  • A GraphQL API so you can easily build tools on top of Aerie
  • A web-based client application

As a multi-tenant system, Aerie allows multiple distributed users to collaborate in real-time on a single plan or concurrently work on multiple plans for multiple missions. Additionally, Aerie's service based architecture allows for efficient system deployment and scalability on the cloud.

Fast Track ⏱️​

Understand Aerie in 5 minutes by trying it out!

  1. Before starting you first need to install Docker on your local machine. The Aerie system is essentially a collection of OCI images.

  2. If you’re running macOS, Linux, or another Unix-like OS you can use following command in your terminal to download the Docker Compose file:

    curl https://raw.githubusercontent.com/NASA-AMMOS/aerie-mission-model-template/main/docker-compose.yml --output docker-compose.yml

    If you're running a different OS and do not have curl available you can download the docker-compose.yml here.

    Note that this compose file starts the latest version of Aerie.

  3. To start the Aerie services you can use the following command in the same directory as the docker-compose.yml file from the previous step:

    docker compose up

  4. Visit http://localhost/ to view the Aerie UI.

    Note that the fast track deployment is not configured to connect to an authentication and authorization provider, therefore any credentials are accepted.

  5. Head over to the planning documentation to learn how to upload a mission model.
