title: Mars Launch System and the Rotational Stability of a Prolate, Spin-Stabilized Spacecraft

description: This paper describes various analyses performed to characterize the rotational stability of the unguided second stage of the Mars Launch System, a key component of the planned Mars Sample Return campaign. The Mars Launch System is a two-stage solid rocket responsible for delivering select Martian samples from the surface of Mars into a tightly constrained orbit for rendezvous with the Earth Return Orbiter. Due to mass and geometry constraints, the second stage of the Mars Launch System would be unguided, prolate, and spin-stabilized. Under torque-free motion, a rotating body experiencing internal energy dissipation will tend towards its minimum-energy state rotating about its axis of maximum moment of inertia. As a prolate vehicle spin-stabilized about its axis of symmetry, any rotational energy dissipation from the Mars Launch System would negatively impact its directional stability. Therefore, it is essential to appropriately characterize and constrain potential sources of rotational energy dissipation and exchange in the system. Requirements on the structural modes of the vehicle can help prevent structural resonance with its rotational dynamics. However, some potential dissipative mechanisms, such as the motion of unconstrained Martian samples inside their collection tubes, are prohibitively difficult to prevent in the vehicle’s design. For these mechanisms, multi-body dynamic models have been developed to help predict the resultant impact of these mechanisms on the vehicle’s attitude stability. The results of analysis thus far have verified the feasibility of the Mars Launch System unguided, spin-stabilized second stage baseline implementation and have allowed guidance, navigation, and control simulations to better model the spacecraft’s stability throughout its burn and payload delivery. The decision to implement Mars Sample Return will not be finalized until the National Aeronautics and Space Administration's completion of the National Environmental Policy Act (NEPA) process.

title: Redundant Flight Computer and File Partition Maintenance Design for the Mars2020 Mission

description: The Mars2020 Perseverance rover is equipped with a variety of redundant avionics to ensure a reliable backup option in anomalous scenarios. Of major importance is the Rover Compute Element (RCE) which includes the primary RAD750 flight computer, nonvolatile memory storage, and in- terfaces to the other avionics assemblies such as the rover’s telecommunications and instruments. The rover is designed to autonomously switch to a backup RCE in a scenario where the prime RCE is continuously faulting, which occurred during the Mars Science Laboratory mission preceding Mars2020. Since the backup RCE could become the prime RCE at any time, it is important to regularly maintain critical files, parameters, and other aspects between the two RCEs that are not automatically synced. Additionally, each RCE contains a primary and backup nonvolatile memory partition. These are also unable to be autonomously synced but can be vital for contingency operations as also seen during the same MSL anomaly. This paper discusses the approach that was developed on the Mars2020 mission for syncing the RCEs at a regular cadence to ensure a safe and expedited return to nominal operations in a swapped RCE scenario. It will cover the original design intent of the redundant flight computer and backup file partitions and elaborate on the MSL anomaly where this design came to be of great use. Next, it will discuss various principles of developing a regular maintenance activity to sync each of these partitions in a way that is non-burdensome for the operations team to accommodate but places each backup partition into a safe and deterministic state. It will also include a discussion of some of the challenges involved in this process and finally illuminate some of the design recommendations for improving this redundancy design for future Martian surface missions like the Mars Sample Return (MSR) Sample Retrieval Lander (SRL).

title: Maintaining Mars Rover Operations Software On A Budget

description: This paper characterizes and discusses the software scripts and tools used by the Mars Science Laboratory rover planner team, and describes the effort to unify the management of this tool suite. Rover Planners have historically used numerous command line tools to aid them in designing and implementing activities over the course of a tactical planning shift. The bulk of these tools were developed ad-hoc by various individuals, with little oversight or organization. As a result, the scripts were poorly documented, difficult to locate, and mostly did not have any formal testing associated with them. As part of the modernization process, we identified all of the existing scripts and their source code locations, moved them to a centralized location within the operations venue, and wrote unit tests and integration tests for every tool. Many tools were upgraded from Python 2 to Python 3, or converted from other languages to Python 3 where feasible. We implemented a system for reviewing changes and continuous testing by moving all scripts to a single git repository, where we track and actively maintain them. Pull requests are tested automatically using Jenkins, and the entire suite of scripts and library functions is tested upon every deployment of the suite. We manage feature requests and bug fixes via GitHub issues, and a working group meets biweekly to discuss changes and progress on efforts relating to software-based tools for the MSL rover planners. In this paper, we detail the design of a unified system for managing these command line tools, the implementation of said system, and the innovation and utility of these tools and how they improve the tactical planning process for MSL Rover Planners. We present this framework as an example for other mission operations teams to use to manage standalone command line scripts that make use of common tools and services.

title: Effusion Cell Development, Testing, and Application for Europa Clipper Outgassing Rate Measurements

description: The Europa Clipper spacecraft’s suite of instruments will be investigating if Jupiter’s moon Europa could harbor conditions suitable for life. Several of these instruments are very sensitive to molecular deposition, whose primary transport is through self-contamination from spacecraft outgassing. The hardware outgassing rate requirements range from 1x10-14 g/cm2/s on the spacecraft exterior to 1x10-12 g/cm2/s inside the Avionics Module, which is significantly lower than previous mission outgassing rate requirements. An effusion cell was developed and implemented in existing thermal vacuum testing facilities at JPL to address the challenge verifying these low hardware outgassing rates. The JPL effusion cell was designed to constrain the transport of outgassed molecules between flight hardware and the Cryogenic Quartz Crystal Microbalances (CQCMs), be compatible with most Europa Clipper hardware, and support outgassing measurement of hardware at Europa operating temperature (50°C to -100°C). The effusion cell improves the fidelity of the CQCM measurement by constraining the test geometry between the flight hardware and the QCM during outgassing rate verification to promote molecular transport of outgassed molecules to the CQCM sensor head. This lowers the sensitivity floor of outgassing rates that can be measured such that the test can verify the low outgassing rate requirements of Europa Clipper. JPL Contamination Control performed tests to characterize the thermal gradient and interior pressure of the effusion cell at Europa operating temperatures. The effusion cell was also modeled in Molflow+ to analyze the transport factor of outgassed molecules to the CQCM sensors. Europa Clipper hardware has verified outgassing rates to the most stringent 1x10-14 g/cm2/s requirement and measured outgassing rates as low as 2x10-15 g/cm2/s using the effusion cell.

title: Early design exploration of space system scenarios using assume-guarantee contracts

description: We present a compositional approach to modeling and analyzing space mission operation sequences with steps across multiple viewpoints. We consider different operation tasks such as communication, science observation, trajectory correction, and battery charging; and separate their interactions across discipline viewpoints. In each sequence step, these tasks are modeled as assume-guarantee contracts. They make assumptions on the initial state of a step, and if these assumptions are satisfied, they guarantee desirable properties of the state at the end of the step. These models are then used in Pacti, a tool for reasoning about contracts. We demonstrate a design methodology leveraging Pacti’s operations: contract composition for computing the contract for the end-to-end sequence of steps and contract merging for combining them across viewpoints. We also demonstrate applying Pacti’s optimization techniques to analyze the figures of merit of admissible sequences satisfying operational requirements for a CubeSat-sized spacecraft performing a small-body asteroid rendez-vous mission. We show that analyzing tens of thousands of combinations of sequences and operational requirements takes just over one minute, confirming the scalability of the approach. The methodology presented in this paper supports the early design phases, including requirement engineering and task modeling.
