This software provides the service-level functionality to manage the delivery of files from a lander mission repository to an orbiter mission repository for eventual space-link relay by the orbiter asset on a specific communications pass. It provides further functions to deliver and track a set of mission-defined messages detailing lander authorization instructions and orbiter data delivery state. All of the information concerning these transactions is persisted in a database providing a high level of accountability of the forward-link relay process.
This is an improvement over legacy processes that required lander client users to log into orbiter mission workstations and run orbiter-specific applications. The legacy process provided only a simple e-mail indicating success of transaction, and no further accounting of the forward-link transaction.
The Phase 2 MaROS forward-file management functions represent a significant upgrade of this relay system. This version provides a lander team the capability of selecting a set of “forward-link” files to be radiated to an orbiter for relay during a chosen communications window. These forward-link files contain critical flight data such as spacecraft command sequences and flight software uploads; this new MaROS functionality is classified Class B software. This new software version also includes the capability for lander and orbiter team members to associate predefined messages to the chosen set of forward-link files. Lander teams can specify authorizations for the orbiter team such as “go for radiation,” and orbiter team members may specify status messages such as “onboard spacecraft.” All of the status data is tracked in a database and provided via a shared service interface. The system provides a high level of accountability into the forward- link process.

Overview
The document is a Technical Support Package for the Relay Forward-Link File Management Services, specifically related to the Mars Relay Operations Service (MaROS Phase 2), developed by the Jet Propulsion Laboratory (JPL) under NASA's auspices. It outlines the objectives, methodologies, and collaborative efforts involved in enhancing communication systems for Mars exploration missions.
The document begins by acknowledging the contributions of various teams and individuals, including the MaROS Working Group and Development Team, emphasizing the collaborative nature of the project. It highlights the strategic planning involved in the deployment of the MaROS system, which is structured in three phases: Strategic, Forward Link, and Tactical. This phased approach ensures that the system is developed systematically to meet the evolving needs of Mars missions.
A key focus of the document is the design principles guiding the development of the MaROS system. These principles include ensuring ubiquitous access through RESTful and web interfaces, creating a mission-agnostic system that can be adapted for future missions, and fostering continuous feedback between mission operators and developers. This iterative process aims to produce a robust and versatile system that can support not only current missions but also future international Mars exploration efforts.
The document also emphasizes the importance of the operations teams from ongoing Mars missions, who have provided valuable insights and assistance in planning and testing the new system. Their involvement is crucial for ensuring that the system meets practical operational needs and can be effectively integrated into existing mission frameworks.
In conclusion, the document serves as a comprehensive overview of the MaROS Phase 2 initiative, detailing its strategic planning, collaborative efforts, and guiding principles. It underscores the commitment to developing a reliable and adaptable communication system that will enhance the capabilities of Mars missions and contribute to the broader goals of space exploration. The document also provides contact information for further inquiries, reflecting NASA's commitment to transparency and collaboration in technological advancements.
