title: Synergistic olfactory processing for social plasticity in desert locusts

description: Desert locust plagues threaten the food security of millions. Central to their formation is crowding-induced plasticity, with social phenotypes changing from cryptic (solitarious) to swarming (gregarious). Here, we elucidate the implications of this transition on foraging decisions and corresponding neural circuits. We use behavioral experiments and Bayesian modeling to decompose the multi-modal facets of foraging, revealing olfactory social cues as critical. To this end, we investigate how corresponding odors are encoded in the locust olfactory system using in-vivo calcium imaging. We discover crowding-dependent synergistic interactions between food-related and social odors distributed across stable combinatorial response maps. The observed synergy was specific to the gregarious phase and manifested in distinct odor response motifs. Our results suggest a crowding-induced modulation of the locust olfactory system that enhances food detection in swarms. Overall, we demonstrate how linking sensory adaptations to behaviorally relevant tasks can improve our understanding of social modulation in non-model organisms.

title: Development of High Power Lithium Magnetoplasmadynamic Thrusters to Support Human Mars Exploration

description: Potential future missions supporting human Mars exploration require major advances in space transportation infrastructure. Hybrid systems of nuclear electric and chemical propulsion are one option under study as part of NASA’s Moon to Mars initiative. To mature relevant technologies and provide data to support mission architecture studies, the Space Nuclear Propulsion project has recently started the development of high power lithium magnetoplasmadynamic thrusters, a potential option for nuclear electric propul- sion. These electromagnetic accelerators offer very high power density and high perfor- mance, having demonstrated over 60% efficiency at specific impulses over 4000 s and power levels of 500 kWe to 1 MWe. Current work is focused on building a 100-200 kWe-class thruster and performing initial shakedown testing of an existing facility that can accommo- date thrusters with power levels up to 2 MWe. Subsequent development would address the remaining technical challenges, including achieving required thruster life, at power levels of 500 kWe to 1 MWe.

title: Comparison of the DYNASIM and CEX2D grid erosion simulation codes in the frame of grid lifetime modeling of the RIT-2X thruster for the Mars Sample Return – Earth Return Orbiter

description: The European Space Agency is currently cooperating with NASA on a Mars Sample Return campaign. The Earth Return Orbiter is one of the European contributions to MSR and the mission is enabled through use of Solar Electric Propulsion. The RIT-2X gridded ion engine of ArianeGroup is under development for the SEP subsystem of ERO. In the frame of ongoing lifetime analyses for the RIT-2X engine for ERO, grid erosion simulations are undertaken by ArianeGroup in partnership with IOM Leipzig, and by the Jet Propulsion Laboratory through the NASA-ESA cooperation framework of MSR. This paper reports on a cross-comparison of the (2D) DYNASIM toolkit of IOM and the CEX2D code of JPL.

title: Temperature Degradation of Magnesium Oxide Cathode Heaters

description: The Advanced Electric Propulsion System (AEPS) consists of a 12 kW Hall thruster with a centrally mounted hollow cathode. The thermionic insert in this hollow cathode is externally heated to approximately 1000°C. Swaged coaxial cathode heaters used for this purpose were tested to characterize failures due to time-at-temperature and to measure the leakage current through the magnesium oxide insulation separating the center conductor from the heater sheath as a function of voltage and temperature. The heaters subjected to time-at-temperature tests demonstrated lifetimes exceeding 500 h at temperatures over 100°C higher than their expected operating temperature. The demonstrated lifetimes are greater than the time-at-temperature that will be accumulated by AEPS heaters in the required number of ignition cycles. The leakage current calculated using the measured bulk conductivity of the magnesium oxide insulator and predicted AEPS heater temperatures was less than 5% of the nominal heater current, a level which will have negligible impact on heater performance.

title: Efficient Arm Motion Planning with Reduced Viapoints for Mars Rover Operations

description: This paper describes additions and enhancements we made to the standard RRT-Connect motion planning algorithm to suit the unique needs of operating the robotic arm on the Perseverance Mars Rover. One constraint of the system is that we need to maintain a minimum distance between the terrain and any part of the arm hardware. Another goal specific to rover planning is to minimize the number of viapoints in our motion plans. These algorithms should also run efficiently so that rover planners can generate arm motion sequences in time for uplink windows. We applied the RRT-Connect algorithm to the rover's robotic arm and tested its performance, and we found that it could be used successfully for rover planning with a few changes. First, we implemented the terrain clearance requirement using a software tool called Proximeter. Second, we simplify the paths computed by RRT-Connect to minimize the number of viapoints in a motion plan. Third, we leverage Proximeter to reduce the number of expensive terrain collision checks done by the algorithm, speeding up motion planning.

title: Characterization testing of the Air Liquide large pulse tube cryocooler (LPTC)

description: An Air Liquide large pulse tube cryocooler (LPTC) was parametrically performance tested for cold tip temperatures between 30 K and 200 K and heat rejection temperatures between 0°C and 40°C. The testing utilized a single off-the-shelf power supply to drive the compressor motors in parallel. The effect of compressor temperature and pulse tube inclination angle are also presented. In addition, the exported forces were measured at ambient conditions and the results are shown and discussed.

title: Ionic Liquid Electrospray Beam Target Performance Characterization

description: Electrospray thruster technologies have been of interest to the space propulsion community for over a decade. The term is broadly used to describe propulsion technologies including colloid thrusters, ionic liquid ion sources, and liquid metal ion sources. At a top level, these technologies operate by the same mechanism – a strong electric field (~109 V/m) is applied to extract charged particles from emission sites to produce useful thrust. This technology offers promise for use on small satellites and for precision pointing on conventional satellites in a distributed manner due to the small form factor and mass (&lt; 5 kg) of the complete system and low power consumption (&lt; 50 W). While there has been substantial work to understand the beam physics and plume dynamics and the implications thereof on performance and lifetime1, there is a gap in an understanding of facility effects. Interactions with an electrospray plume and the vacuum chamber test facility has implications on both performance and lifetime. Therefore, any effort to characterize an electrospray thruster must be done so with an understanding of how the facility plays a role. In some ways, this is no different than the significant investment that has been made to understand the facility effects for the testing of plasma thrusters. However, there are different challenges involved with the management of positively charged, negatively charged, and neutral particles across a distribution of particle charge and mass as is observed when testing the technologies in a vacuum chamber. The focus of this paper is a characterization of the secondary particles from the impact with an electrospray beam target for ionic liquid thrusters. As part of this work, a purpose-built electrospray beam target was fully characterized. Results on secondary current and mass flux is presented as well as some initial results on secondary time-of-flight measurements. Additionally, modeling results are presented to inform the experimental observations. The results show that mitigating facility effects, while a challenge, can be done with the appropriately designed and biased beam target. If no consideration of facility effects is accounted for when testing electrospray thrusters, performance, reliability, and lifetime can be adversely affected and premature thruster failure may result. The work presented here improves our test capabilities to responsibly and successfully qualify and acceptance test electrospray thrusters for flight for long duration missions.

title: Look Mob, No Hands! Automating Mobility Downlink for the Mars Science Laboratory

description: Now 11 years into its mission, the Mars Science Laboratory’s Curiosity Rover has conducted over 1000* drives, with 83%* of those drives successfully reaching their intended destination. No matter success or failure, it is the job of the Mobility downlink chair to assess the performance of all drives that Curiosity executes, examining telemetry to look for anomalous behavior and diagnose the cause of drive faults when the rover does not reach its target. This tactical assessment of drive performance should occur in under 45 minutes, and at the end of which the Mobility chair provides a Go or No-Go for rover planning to proceed. During downlink assessments when a drive occurred, the Mobility chair is responsible for reporting on 16 aspects of mobility performance, only 3 of which require human judgement, meaning the assessment of the other 13 could potentially be fully automated. Automating the downlink assessment and report generation of the Mobility chair addresses two primary challenges faced by the Mars Science Laboratory Mission: reduced funding in extended mission and a desire to increase operational efficiency. This paper reports on the effort made by the authors to automate large parts of the downlink assessment for the mobility subsystem of MSL. The design decisions made for this application of downlink automation are detailed and considerations for future missions are provided for use in the development of their downlink systems to facilitate for reduced need of humans-in-the-loop. Since implementing the introduced automation method, over 80% of the work for the Mobility downlink chair is handled automatically, and assessment times for drives that execute successfully have dropped to under 10 minutes. In the event of a failed drive, the automation method still conducts 80% of the assessment, freeing up over 30 minutes for the Mobility chair to fully investigate the fault and provide an in-depth report, increasing confidence and accuracy in their Go/ No-Go assessment. For a mission still in development, designing their systems to operate with this increased efficiency from day 1 of the mission would pay dividends over the course of the primary mission, and become invaluable in the event of an extended mission.

title: Cathode-plume Instabilities Onset and Detection in Hollow Cathodes for Electric Thrusters

description: Three dominate plasma instabilities have been identified in the literature to exist under various conditions in the near cathode plume of hollow cathodes used in electric thrusters. These instabilities contribute strongly to the noise in the plasma discharge and the generation of energetic ions that affect thruster component life. The three instabilities are low frequency (&lt;100 kHz) ionization instabilities (reminiscent of predator-prey instabilities in Hall thrusters), turbulent ion acoustic instabilities at higher frequencies (&gt;200 kHz), and rotational instabilities that are found with an applied magnetic field similar to that found in the thruster and also operate at lower frequencies (&lt;100 kHz). A set of emissive and Langmuir probes have been positioned in the near-plume region of a laboratory hollow cathode discharge and used to detect each of these instabilities and characterize their onset and mode competition or coupling. The amplitude and direction of the energetic ions generated during the presence of these instabilities is different depending on which instabilities are present. The instabilities produce a more gradual transition from the quiescent “spot” mode to the noisy “plume” mode that starts at higher flow rates than originally observed in ion thruster neutralizer cathodes, largely because the higher discharge currents and presence of applied magnetic fields in these experiments tend to drive multiple oscillations to exist at the same time with increasing amplitudes.

title: The Small Mobile Ozone lidar (SMOL) - Development and validation

description: Ozone profile measurements at high temporal and vertical resolution are needed to better understand physical processes driving tropospheric ozone variability and to validate the tropospheric ozone measurements from spaceborne missions such as TEMPO (Tropospheric Emissions: Monitoring Pollution). As part of the Tropospheric Ozone Lidar Network (TOLNet) efforts allocated to provide such measurements, and leveraging on the experience of more than 20 years of ozone lidar measurements at Table Mountain Facility, the JPL lidar group developed the SMOL (Small Mobile Ozone Lidar), an affordable differential absorption lidar (DIAL) system covering all altitudes from 150 m to 10 km a.g.l. In this abstract, we will review the main characteristics of SMOL, the preliminary results of its first field deployment during the Synergistic TEMPO Air Quality Science (STAQS) and Atmospheric Emissions and Reactions Observed from Megacities to Marine Areas (AEROMMA) campaigns in summer 2023, as well as discuss upcoming deployments and collaborations.
