title: Integrated Science and Engineering Simulation Environment for Formation Flying Mission around Small Body

description: In this paper, we present a novel integrated simulation tool that models science yield and mission resources as a func- tion of science payload, mission and system design, spacecraft behavior and modes, and target uncertainties. This provides a comprehensive and self-consistent approach to multi-spacecraft mission formulation around small bodies. We demonstrate this tool for the case of a notional three-spacecraft mission to the near-Earth asteroid Apophis, which will flyby Earth in 2029.

title: The Optical to Orion Time of Flight Ground Processing System

description: Free space optical communication will increase data rates and science returns from deep space. The Optical to Orion (O2O) project will demonstrate these high-rate links on the Artemis-II mission, showcasing this technology for the first time on a crewed mission from cis-lunar space. This new paradigm of optical communication necessitates a re-evaluation of other core functionalities of remote spacecraft operation, including guidance, navigation and control. Existing RF-based ranging methods can exploit the structure of the communication signal in order to infer the range and range-rate of the spacecraft (known as synchronous two-way ranging), but optical communication utilizes a totally distinct communication signal format. The CCSDS is in the process of standardizing an optical-based method under the moniker High Photon Efficiency Telemetry Ranging, which has its origins in the technique pioneered on the Lunar Laser Communication Demonstration (LLCD). A variant of this technique is used in O2O’s Time of Flight (ToF) system, enabling highly accurate, real time ranging capabilities for the Artemis-II mission.In this paper we describe the ground signal processing implementation of O2O’s synchronous two-way ranging scheme with centimeter-class accuracy. In contrast to the technique used in LLCD, the O2O Time of Flight system utilizes a hardware architecture based on a high dynamic-range Time to Digital Converter (TDC)-based receiver. We describe the architecture of the Time of Flight capture system, as well as the hardware and software necessary to extract range and range-rate information from the downlink and uplink signals. We also describe a novel calibration scheme that enables highly accurate compensation of the delays within the ground station without the explicit need to measure individual path lengths. We conclude the paper with simulation and experimental results validating the implementation.

title: CORRECTING FOR ROLLING SHUTTER DISTORTION IN DART OPTICAL NAVIGATION IMAGERY

description: A key process in optical navigation (opnav) is the use of observed star centers, combined with a known camera model, to derive the pointing of a given picture1. This process typically produces attitude accuracies on the order of a tenth or hundredths of a pixel. However, as CMOS detectors become increasingly common in opnav cameras, so to does the use of a rolling shutter, as is the case for the Double Asteroid Redirection Test (DART) Didymos Reconnaissance and Asteroid Camera for Opnav (DRACO). A rolling shutter means that as the spacecraft deadbands, each readline is exposed at a slightly different attitude, thus distorting the resulting star pattern, and potentially inducing error to the process of estimating picture attitude. This paper details these effects on DRACO imagery, and the techniques developed to counteract them.

title: A Python Library for Trace Analysis

description: We present a Python library for trace analysis called PyContract. PyContract is a shallow internal DSL, in contrast to many trace analysis tools that implement external or deep internal DSLs. The library has been used in a real project for analysis of logs from NASA’s Europa Clipper mission. We believe that this opportunity arose largely because of the choice of Python as a host language for the DSL. We describe our design choices, including the argument for developing a Python library, and explain the implementation. The paper includes experiments comparing PyContract against other state-of-the-art tools from the research and industrial communities.

title: System Level Availability Budget for the Multi-Vehicle Sun Radio Interferometer Space Experiment

description: The Sun Radio Interferometer Space Experiment (SunRISE) will be the first space-based radio interferometer. Comprised of six identical 6U vehicles carrying decametric-hectometric radio and GNSS receiver payloads, the SunRISE Observatory orbits Earth slightly above GEO to measure solar radio bursts associated with solar coronal mass ejections (CMEs) and solar flares. Because the solar radio bursts that SunRISE will observe are inherently unpredictable, the SunRISE Observatory must have a long enough observing time in order to observe a sufficient number of solar radio bursts to satisfy the Level 1 Science requirements. The observing time is the product of two factors, the total duration of the prime science mission and the fraction of that time that can be used for science or the “Observatory availability”. In practice, solar radio bursts associated with CMEs, so-called Type II bursts, are less frequent, and the requirement to observe a sufficient number of them drives the resulting set of lower-level requirements. The “Observatory availability budget” is a mission-unique system-level budget that aims to guarantee science closure by synthesizing various, apparently disjoint, factors. The factors considered range from typical to more exotic. Typical considerations include time spent downlinking data or conducting orbital maneuvers, considerations of reliability and infant mortality, and expectations for spacecraft and payload hardware and software. Special considerations include the three-dimensional geometric arrangement of the vehicles in space and the extent to which they are in a configuration and with separation sufficient to form an interferometer with the required performance. This paper describes these factors and shows how we have assessed the Observatory availability budget to ensure that the Observatory is online greater than 90% of the time in order to observe a sufficient number of Type II radio bursts. The relevant requirements decomposed from this budget pertain to upset frequencies and durations, planned outage limits, mission duration, and fault protection/management and autonomy needs for the vehicles. This Observatory availability budget also informs mission plans for downlink/uplink and maneuver durations and cadences. This paper provides background on how the 90% availability requirement was developed, and focus on how the Observatory availability budget factors were identified and estimated, the statistical Monte Carlo-based model built to synthesize them, and the philosophy developed for how to interpret the results and evaluate compliance and margin. Of particular interest, we will discuss how SunRISE’s architecture of six identical vehicles provides on-orbit redundancy, which is critical to the resiliency of this budget, allowing it to degrade gracefully with anomalies.

title: Sources with Significant Astrometric Offsets Between the S/X and K-band Celestial Frames

description: The latest astrometric celestial reference frame (CRF) solutions at S/X-band and K-band have 1014 sources in common, of which 36 are outliers with significant differences between the X and K-band coordinates. We investigate possible astrophysical reasons for the large differences seen for the 36 outlier sources. These large differences may indicate significant structural differences between S/X and K-band. In order to study the astrophysical differences, we conducted multi-epoch, quasi-simultaneous S/X and K-band astrometric and imaging observations using the Very Long Baseline Array (VLBA). These images allow us to directly compare the source structure at X and K-band and allow us to compare the direction of the extended emission from our imaging to the astrometric offset direction obtained from our CRF solutions.

title: Bias Compensated Inertial Navigation for Venus Balloon Missions

description: —In this paper we investigate various strategies forreducing navigation errors for a future Venus Balloon missionequipped with a low-mass MEMS IMU (e.g. STIM300), andfocus on two of these mitigation strategies in detail. First, weproposed to mechanically rotate the IMU while collecting datathereby averaging out the bias contributions and increasingaccuracy. To this end, we experimentally provide proof-ofconcept by rotating a STIM300 IMU about a single-axis andshow that navigation performance for this idealized scenario issubstantially improved. Second, we propose to use on-boardaccelerometer measurements to exploit the projection of thegravity field along the axes of the IMU frame to provide (2 axis)attitude information. To this end, we design a Kalman Filterfor a hovering balloon scenario where the accelerometer measurements are modeled as explicit functions of attitude and areincorporated as direct measurements in the filter and show thatthis strategy leads to improved navigation performance. Theresults given here are part of a longer-term effort to understandand improve navigation performance on a Venus Balloon andshould be considered as first steps toward this goal.

title: Machine-Learned Data Compression for Outer Solar System Missions

description: It is easy to take for granted our ability to draw scientific information from distant interplanetary spacecraft, particularly those in outer solar system missions. The Cassini Imaging Science Subsystem (ISS), for example. has returned a wealth of high-resolution images of Saturn and its moons, enabling detailed scientific retrievals of anomalies in Saturn’s rings and the atmosphere of Titan. But in reality, all data received from an outer solar system mission must overcome severe constraints on a spacecraft’s available power, antenna size, and bandwidth for transmitting data back to Earth. Given the enormous cost of these missions, the pressure is high on scientists to have not only a high return of data, but a pristine quality thereof. As such, many science teams have an aversion to employing lossy compression techniques, despite their promise to allow for a substantially higher data return, since many are known to introduce artifacts into data. Such was the case for the Cassini ISS, whose hardware-implemented JPEG compressor introduced large blocking artifacts in camera images, necessitating the need for overly conservative compression. It was demonstrated in [1] that off-the-shelf compressors could be fine-tuned to effectively cater to specific data sets without compromising their scientific integrity. In this paper, we take this a step further by incorporating machine learning to automate the selection of the compressor and its parameters. In particular, we use neural networks to generalize the compression models which were found to perform well in the previous study, and incorporate aspects of the scientific retrievals into both the training process and the structure of the networks. We show how, in some cases, machine learning can supplement the previous algorithms, and demonstrate the performance on detached haze retrievals of Titan from Cassini images. We then present a novel neural network model and algorithm which implements machine-learned transform coding, a complete generalization of the algorithm from [1]. We demonstrate its performance on two classes of data from the Cassini mission: 1) tie-point matching in flyby sequences of Tethys, and 2) measuring propeller structures in the rings of Saturn. We also discuss modifications of our original algorithm to incorporate machine-learned estimation of optical flow between sequential images, as well as the use of discriminator networks trained adversarially with our compression/decompression networks to distinguish compression error from noise. Our system is data-driven, achieving higher compressibility when trained on more particular datasets, and allows for trading off between incorporating prior knowledge of the ambient structure and noise in the data versus allowing the networks to learn this for themselves. Furthermore, our algorithms are portable, and we demonstrate high performance from lightweight networks, which can be quickly trained and easily uploaded.

title: Enabling standardized, efficient system level test campaigns via the Ingenium electronic procedure system.

description: The Ingenium electronic procedure system was developed at the Jet Propulsion Laboratory to both standardize and streamline system level test campaigns. This software suite allows integration and test engineers to develop test procedures that can be executed on a variety of test venues, from simulators to flight vehicles. Ingenium executes these procedures electronically by directly interfacing with the ground system and can support both manual and fully automatic modes. These procedures are developed within the Ingenium web application and provide easy integration with both spacecraft dictionaries as well as Verification and Validation (V&V) artifacts. The standard format, both visually and electronically, supports flattening the learning curve for personnel as well as enabling standard tooling for augmenting the system for project specific needs. Ingenium has been deployed on the Psyche and Europa Clipper missions and used for the majority of all system level tests including all testing with the flight vehicle.

title: FModal: A Flexible Body Dynamics Modeling Pipeline for G Analysis

description: In this article, we describe the FModal tool that has been designed to bridge the gap between the structural dynamics and GC domains to develop a pipeline to facilitate the use of high-fidelity flexible body models for GC development. FModal streamlines the process of generating modal data including residual vectors and modal integral terms from component NASTRAN structural dynamics models for use in flexible multibody dynamics tools. The data generation process can be tailored to meet the simulation fidelity and performance needs. FModals output is a portable HDF5 file with hierarchical, well-organized, and labeled data that can be interfaced with multibody tools to automate and simplify the model data transfer process. FModal can be used to extract the critical data needed for flexible multibody dynamics simulations from a NASTRAN structure model and automate the transfer to a multibody dynamics and GC analysis tools. FModal can thus reduce the time needed to create flexible body models and errors in the model transfer process leading to faster design iterations and reduced time and costs. In this paper, we describe the interface between FModal and the DARTS flexible body dynamics tool and several validation studies to exercise and validate this new pipeline.

This transformation of a new methodology was based on the Venn diagram of people, process, and tools, i.e., underlying IT infrastructure and technical models [ ].
