title: JWST Detects the Forbidden 1.707-micron SO Emission Band Complex above Io's Active Volcano Kanehekili Fluctus

description: We observed Io while in eclipse as part of our JWST-ERS program #1373, with NIRSpec/IFU in the G235H/F170LP and G395H/F290LP set-up on 15 November 2022. We detected thermal emission from several volcanoes. Kanehekili Fluctus was exceptionally bright, and Loki Patera had most likely entered a new brightening phase. Spectra at a resolving power R ≈ 2700 were recorded between 1.65 and 5.3 μm, and were matched by a combination of blackbody curves that showed that the highest temperature, ∼1200 K, for Kanehekili Fluctus originated from an area ∼0.25 km2 in size, and for Loki Patera this high temperature was confined to an area ∼0.06 km−2 in size. Lower temperatures, down to 300 K, cover areas of ∼2000 km2 for Kanehekili Fluctus, and ∼5000 km2 for Loki Patera. We further detected the a1Δ ⇒ X3Σ− 1.707 μm rovibronic forbidden SO emission band complex over the southern hemisphere, which peaked at the location of Kanehekili Fluctus. This is the first time this emission has been seen above an active volcano, and suggests that the origin of such emissions is ejection of SO molecules directly from the vent in an excited state, after having been equilibrated at temperatures of ∼1500 K below the surface, as was previously hypothesized.

title: Roman Space Telescope Coronagraph Technology Demonstration: Current Status and Relevance to Future Missions

description: The Nancy Grace Roman Space Telescope (formerly WFIRST) will be launched in the mid-2020s with an onboard Coronagraph Instrument which will serve as a technology demonstrator for exoplanet direct imaging. The Roman Coronagraph will be capable of detecting and characterizing exoplanets and circumstellar disks in visible light at an unprecedented contrast level of ~10-8 or better. Such a contrast level, which is 2 to 3 orders of magnitude better than state-of-the-art visible or near-infrared coronagraphs, raises entirely new challenges that will be overcome using a combination of hardware, calibration and data processing. In particular, the Roman Coronagraph will be the first space-based coronagraphic instrument with active low- and high-order wavefront control through the use of large-format deformable mirrors, and its electron-multiplying Charge Coupled Device (EMCCD) detector will enable faint signal detection in photon-counting mode. The Roman Coronagraph passed its critical design review (CDR) successfully in April 2021 and its system integration review in June 2022. It is now well on its path to demonstrate many core technologies at the levels required for potential future exo-Earth direct imaging missions.

title: Design of the Juno Extended Mission Trajectory

description: The Juno extended mission trajectory design represents the culmination of a two- year collaborative effort between the Juno navigation, science, spacecraft, and project management teams. This paper presents the science and trajectory de- sign trades explored and quantifies the ∆V impacts associated with various op- tions. Science orbit period and equator-crossing longitude grid considerations are also discussed. Ultimately, the Juno extended mission trajectory is enabled by a design methodology yielding four low-altitude Galilean satellite flybys that lower orbital period and dramatically reduce mission ∆V costs while providing exciting, previously-unanticipated scientific observation opportunities.

title: Design and Implementation of the Juno Eclipse Avoidance Maneuver

description: The Juno spacecraft is the first solar-powered spacecraft to travel to the outer planets and is powered by three, nearly-9-meter solar arrays with an average output of over 500 W. As such, it is critically important to maintain sunlight on the solar arrays and the Juno reference trajectory design included only a single, 19-minute eclipse during a 550-km Earth gravity-assist in October 2013. Previous iterations of Juno’s polar, 32-orbit science campaign leveraged orbital periods of 11 and 14 days with mission end times in October 2017 and February 2018, respectively, and included no science phase solar eclipses. However, the decision in October 2016 to cancel Juno’s Period Reduction Maneuver (PRM) and remain in the 53-day capture orbit indefinitely necessitated Juno traversing a Jovian “eclipse season” to complete its required 32 science orbits.1 Without intervention, Juno would have encountered a nearly-12-hour eclipse in early November 2019 that would have almost certainly been mission-ending. Fortunately, the Juno Navigation Team was able to identify a deterministic maneuvering strategy to avoid solar eclipse entirely and add years to Juno’s operational lifetime. While Juno’s notional eclipse avoidance maneuver strategy was previously summarized by Pavlak et al.1 primarily in the context of selecting Juno’s science orbit period following PRM cancellation, this paper details the operational considerations and complexities associated with designing and implementing Juno’s comprehensive eclipse avoidance campaign. This discussion includes topics such as single-burn vs. multi-burn approaches, backup maneuver opportunities and associated V costs, burn timer selection methodology, and eclipse duration as a function of burn completion percentage. Lastly, this paper analyzes Juno’s eclipse avoidance maneuver as-executed and assesses the performance and delivery accuracy against pre-maneuver predictions.

title: Reliability Modeling of Complex Components Using Simulation

description: This paper is a continuation of papers presented at the 13th and 15th Probabilistic Safety Assessment and Management Conferences [1, 2]. The previous work presented discussions of modeling failure modes of complex components and the effects of censor bias. The first paper demonstrated how the typical method of treating failure modes as exponential gives optimistic predictions when predicting how improvements to subcomponents will perform. Instead of relying on traditional analytical methods, a more accurate approach is to model the failure modes as a race in time. Unfortunately, this does not give a closed-form solution and requires a more advanced solution. A simulation with pre-defined component attributes demonstrated the optimistic nature of classical techniques. Unfortunately for complex systems, the simulation routine may become very complex and difficult to implement. The second paper demonstrated the effect of censor bias when dealing with large amounts of success-only testing, and the difference between treating data as "missing" instead of censored.In the quest for closed-form solutions and simplicity, the world of reliability engineering relies on the exponential distribution. In most cases, it makes the solution closed-form and easy to solve. However, simple models may lead to incorrect results when modeling even something as simple as modeling to the failure mode or component/subassembly level. An excellent real-world example of using exponential distributions in this context is the typical automobile. No one expects a new car to have the same failure intensity as an older car. Obviously a more advanced approach is needed, and not just at the component level.This paper will use two approaches to analyze a simple system with components that have more than one failure mode. The first is a standard fault tree, and the second is a simulation. In both methods, various data assessment methods will be used to compare the results of both the data assessment method and the solution. A discussion of the results will follow.

title: ExEP: Completion of model validation experiments at the Princeton starshade testbed

description: Following the results of Starshade Milestone 1 in which we demonstrated broadband contrast better than $10^{-10}$, we have performed model validation experiments to show that diffraction models accurately predict the contrast due to perturbations representing the building blocks of the instrument error budget. The perturbations include the displacement of petal edge segments, sinusoidal petal edge shape deformations, global petal position errors, and random petal radial placement errors. We also show that the model accurately predicts the combined effects of two errors. The experiments result in a measured Model Uncertainty Factor (MUF) that is then applied to the starshade instrument contrast error budget.

title: ORBIT DETERMINATION PERFORMANCE OF THE JUPITER ECLIPSE AVOIDANCE MANEUVER BY THE JUNO SPACECRAFT

description: In the fall of 2019, the Juno spacecraft (s/c) was on a trajectory that would lead to its complete loss of power and eventual impact with Jupiter. Were nothing to be done, on November 3, 2019 the Juno spacecraft would incur a mission-ending, ∼12-hour solar eclipse due to entering Jupiter’s shadow. However, one month prior, a cleverly designed eclipse avoidance maneuver was successfully performed to reorient the orbital plane, allowing us to “skip over” the shadow cone. This paper will detail the orbit determination (OD) team’s preparation for this critical event, and the subsequent analyses done to understand how well the spacecraft performed the maneuver and where the future of the mission stood.

title: ACTIVE TERRAIN RELATIVE NAVIGATION FOR LUNAR LANDINGS

description: Landing on a planetary body is an important part of space exploration. Precision landing capability enables a pin-point touchdown on the planet surface to con- duct scientific exploration. Terrain Relative Navigation (TRN) is an autonomous navigation technique to achieve precision landing. A Camera-based Passive TRN system has been proven successful in the Mars 2020 mission. However for un- illuminated locations, Active TRN is needed to achieve precision landing. In this paper, the performance of a lidar-based Active TRN concept for lunar landing is investigated using numerical simulations and publicly available altimetry data.

title: DERIVING EVENT THRESHOLDS AND COLLISION PROBABILITY FOR AUTOMATED CONJUNCTION ASSESSMENT AT MARS AND THE MOON

description: It is well known that conjunction assessment is necessary in the Earth orbiting environment to prevent spacecraft collisions and reduce debris in orbit. Alt-hough there are many fewer spacecraft in orbit around Mars and the Moon, the number of missions to these bodies is increasing rapidly and the consequences of creating debris riskier due to the inability to track debris objects in those en-vironments. The Multimission Automated Deepspace Conjunction Assessment Process (MADCAP) is used at the Jet Propulsion Laboratory (JPL) to perform conjunction assessment at Mars, the Moon, and Sun/Earth libration points. Previous papers have described this process and its development. Conjunction assessment of spacecraft trajectories produces many close approaches which must be screened in order to inform users when a specific event may be of concern. Probability of Collision (PC) is the main attribute used for screening conjunc-tions in the Earth orbiting environment. Trajectory uncertainty information in the form of covariance data is required to calculate the PC. However, covariance data is not as easily obtained for objects in the Lunar and Martian environments. Instead, various attributes of the close approach must be calculated and com-pared against thresholds based on typical expected orbit uncertainty. These thresholds are best informed by the individual spacecraft navigation teams who are most knowledgeable about the spacecraft’s orbital uncertainties. This paper will explore the development of the thresholds used in MADCAP and provide a guideline for navigation teams to derive them from their orbit determination analysis. A method for the derivation of close approach attribute thresholds from covariance data, when it is available, is also described. Finally, collision probability calculations are examined, with exploration of methods for approximating probabilities when covariance data are limited.

title: Limb-based Autonomous Navigation and Mapping of Primitive Bodies

description: This paper describes a method to estimate the visual hull and relative pose of a small celestial body with limb information extracted from images. The visual hull is the shape that can be reconstructed using silhouette, and it is contains the actual shape of the object, but it is entirely contained within the convex hull instead. The shape of the small body is represented with a Gaussian Process, which provides a continuous representation of the surface and corresponding uncertainty

title: Near-full-depth profile observations of water properties and currents at four deep-ocean sites

description: The Ocean Observatory Initiative (OOI) funded by the U.S. National Science Foundation established four deep ocean observing sites between summer 2013 and spring 2015: Argentine Basin (42˚ 58.9’ S, 42˚ 29.9’ W, water depth 5200 m), Southern Ocean (54 ˚ 28.1’ S, 89˚ 22.1’ W, 4800 m), Station Papa (50˚ 4.2’ N, 144˚ 47.9 W, 4219 m), and Irminger Sea (59˚ 58.5’ N, 39 ˚ 28.9’ W, 2800 m). Each site was instrumented with four closely-spaced moorings of various design supporting a variety of sensors. As no single OOI mooring in these arrays provides temperature, salinity and horizontal velocity information over the full water column, observations from two or more moorings were combined to produce vertical profiles at ½-dbar vertical resolution of sea water temperature, salinity, east and north velocity and vertical displacement. These profile data are reported here.
