title: Lessons From Ingenuity’s Climb Up Jezero Crater Delta

description: As Perseverance began exploring the delta of Jezero crater, the Ingenuity team took on the most ambitious flights of the mission to date. Designed for the relatively flat terrain of the crater floor, the Ingenuity team now needed to climb up and fly through the rocky channels of the Jezero delta. Before the flights in the delta could even be attempted, the team needed to upgrade Ingenuity’s flight software to identify landing hazards and utilize digital elevation maps in the navigation filter. After upgrading the flight software, the team needed to work through a series of checkout flights to validate this new functionality prior to climbing the delta. The Jezero delta features narrow channels, limiting Ingenuity and Perseverance’s available traverse paths. This required Ingenuity and Perseverance to follow similar routes, necessitating new processes for coordinating Ingenuity and Perseverance’s parallel flights and drives. In previous traverses, Ingenuity was able to take separate, shorter routes to the destination, but this climb required Ingenuity to keep pace with Perseverance’s record setting drives. This rapid traverse pushed the Ingenuity team to optimize the flight planning process to shorten the nominal two week flight cadence to under a week between flights. The narrow passages of the delta also limited Ingenuity’s telecom propagation, providing only small windows of strong communication with Perseverance. All these above constraints required the Perseverance and Ingenuity teams to carefully orchestrate both vehicles’ journey up the delta, keeping both vehicles in lockstep while minimizing the chance that one vehicle would hold up the other’s progress. The paper will cover flight 34 and beyond, Ingenuity’s delta climb, as well as the lessons learned from both the challenging flights in the delta terrain and the required multi-vehicle coordination of the climb.

title: Prototype Testing of the AMR-CR Instrument: Drivers, Implementation, and Results

description: The CRISTAL mission will perform critical cryosphere science and is the next evolution for ocean topography measurements in the polar regions. The instrument suite on CRISTAL includes the Interferometric Radar Altimeter for Ice and Snow (IRIS) and the Advanced Microwave Radiometer for CRISTAL (AMR-CR), which will support the secondary ocean altimetry mission objective by providing correction for the radar path delay due to atmospheric water vapor. The AMR-CR instrument is a 6- channel radiometer with significant heritage from former AMR missions, such as those flown on Sentinel-6 and Jason-3. Many elements of the instrument design were inherited from previous missions, including the RF electronics, structural design, and calibration system, but some updates were made to the design to modernize the electronics, software, and programmable logic in the instrument. Merging the updated electronics with the inherited framework posed unique challenges and introduced risk of self-compatibility or performance issues arising post instrument integration, at which point issues are more difficult to correct and have greater impact to cost and schedule. In response to these risks, the project pursued a prototype test campaign prior to the start of flight hardware integration. This paper describes specific differences, both internal and external, between CRISTAL AMR-CR and Sentinel-6 AMR-C that led to the selection and execution of two high priority test cases. The test results validated the functionality of the updated electronics and indicated their compatibility with the inherited receivers and spacecraft interfaces.

title: Gaia GraL: Gaia DR2 Gravitational Lens Systems. VIII. A radio census of lensed systems

description: We present radio observations of 24 confirmed and candidate strongly lensed quasars identified by the Gaia Gravitational Lenses (GraL) working group. We detect radio emission from 8 systems in 5.5 and 9 GHz observations with the Australia Telescope Compact Array (ATCA), and 12 systems in 6 GHz observations with the Karl G. Jansky Very Large Array (VLA). The resolution of our ATCA observations is insufficient to resolve the radio emission into multiple lensed images, but we do detect multiple images from 11 VLA targets. We have analysed these systems using our observations in conjunction with existing optical measurements, including measuring offsets between the radio and optical positions, for each image and building updated lens models. These observations significantly expand the existing sample of lensed radio quasars, suggest that most lensed systems are detectable at radio wavelengths with targeted observations, and demonstrate the feasibility of population studies with high resolution radio imaging.

title: Data for: Experimental evidence of slight alteration of male Collared Flycatcher songs based on the female audience

description: Bird song is an important and variable sexual signal in many passerine species. One function of this variability may be that males show mate choice and can alter their song according to the quality of the female to which they presently sing. If attractive songs are costly, we can hypothesize that males sing more attractively or invest more in singing when trying to attract a better quality partner. We tested this hypothesis with a field experiment in a wild population of Collared Flycatchers <i>Ficedula albicollis</i>. We presented female stimuli differing in the amount of plumage ornamentation to males on their territory and then recorded their song. We repeated the experiment at least twice for each individual with different female stimuli. We obtained 67 recordings from 29 males, each with 10-50 song responses. Five song traits (song length, mean frequency, frequency bandwidth, tempo and complexity) were extracted from the recordings and were used in further analyses examining whether the identity of the focal male and the female stimuli explain variance in song traits and whether males change their songs when exposed to different females. While among-individual variance was considerable in all investigated song traits, female stimuli explained variance only in complexity and tempo. This indicates that males alter these song traits if they sing to different females. We could not clearly identify whether the difference in the response to female stimuli was driven by female quality either at population or individual levels. Overall, our results reveal individuality in song plasticity, and suggest that male mate choice may exist in this species.

title: Achieving Mission Success: A Comprehensive Look at the Verification and Validation Approach for the Psyche SpacecraftMission – the First Demonstration of Hall Thrusters in Interplanetary Space

description: On October 13, 2023, the Psyche spacecraft launched from Kennedy Space Center aboard a Falcon Heavy Rocket, marking the first use of SPT-140 Hall thrusters for interplanetary propulsion, supported by a cold gas system for launch separation, faulted conditions, and counterbalancing the momentum of the electric propulsion thrusters. This paper explores the system-level verification and validation campaign, covering spacecraft integration, environmental testing, launch and cruise validation, and flight operations transition. The test program had to balance the use of flight, engineering, and simulation models, particularly in closed-loop guidance, navigation, and control testing. The paper details the mission operations validation approach, addressing challenges in hardware-software compatibility and the unique demands of a low-thrust, electric propulsion deep-space mission.

title: Dataset of Haldane Fractional Statistics for 1D Heisenberg Spin XXX Chain

description: Haldane's fractional exclusion statistics (FES) describes a generalized Pauli exclusion statistics, which can be regarded as an emergent quantum statistics induced by the intrinsic dynamical interaction. A non-mutual FES has been identified at the quantum criticality of the one-dimensional (1D) and 2D interacting Bose Gas [Nat. Sci. Rev. 9, nwac027 (2022)]. It is naturally asked if such a non-mutual FES can be induced by the spin-spin interaction in the antiferromagnetic spin-1/2 XXX chain? In this article, we first represent the Bethe ansatz equations of spin strings in terms of the FES equations of different species. Then we show that the 1D spin XXX chain remarkably possesses the non-mutual FES in the critical region. We observe that the equation of state in terms of the FES gives rises to full statistical properties of the model at quantum criticality, which are in good agreement with the results obtained from the thermodynamic Bethe ansatz (TBA) equations of the model. From the non-mutual FES, we also precisely determine the quantum scaling functions, which further agree well with the previous TBA results [Phys. Rev. B 96, 220401(R) (2017)]. Finally, we also build up an exact mapping between the scaling functions of the Lieb-Liniger model and the spin Heisenberg spin chain at quantum criticality. Our method provides deep insights into the critical phase of matter from quantum FES point of view.

title: EMIT: Delivering a Complex Payload for the International Space Station

description: Abstract— EMIT (Earth Surface Mineral Dust Source InvesTigation) was selected in February 2018 as part of the Second Stand Alone Mission of Opportunity Notice (SALMON-2), Program Element Appendix (PEA): Earth Venture Instrument-4. From the start, the EMIT integration and test program was going to be complicated by the complexity of the payload and restrictions on being able to do the dynamics qualification in the full flight configuration. During formulation phase (Phase B), the team elected to separate the instrument into three structurally independent elements – one for the optics, one for the avionics, and one for enclosure and radiators. Taking this approach greatly complicated the planning for the assembly phase, but offered several potential advantages in planning the integration and test program.After the EMIT project preferred flow was defined for the EMIT PDR, those plans were upended by the arrival of COVID. The EMIT team faced a situation where most, but not all, components were going to be delivered late – with large uncertainties on the relative delays. This uncertainty led to review of the assembly flow and finding ways to decouple the three primary integration flows. Other considerations included building additional ground support equipment to permit work to continue on much of the system in the event critical flight parts arrived even later than expected. In hindsight, this fixation on finding schedule resiliency should have been part of the original plan. This paper will provide an overview of the instrument design, how the three major assemblies were designed to be tested independently, and specific decisions made to ensure maximum flexibility to make progress and reduce technical risk should key elements be delivered late. Examples will include early decisions to build extra copies of engineering models, to create temporary facilities to optimize the test flow, and to rearrange the test orders to find ways to reduce risks on partial assemblies while waiting for late deliveries.
