title: The Evolution of Deep Space Navigation: Prologue I

description: An existing series of papers has described the evolution of deep space navigation over the time interval 1962 to 2020. This paper complements the series by examining a broad range of prior or contemporaneous events, starting in the post-war years, that contributed to the successful navigation of NASA’s planetary missions of the early 1960s. Such events include post-war tests of sounding rockets and ballistic missiles; the tracking of the first Earth satellites; the construction and early evolution of what became the Deep Space Network; the creation of the first two generations of high-precision orbit determination and related trajectory software for lunar and planetary missions; and experience gained from navigating multiple NASA missions to the moon or into heliocentric orbit.

title: Evaluation of the Acoustic Test Field Generated by Two Direct Field Acoustic Test Methodologies Compared to a Reverberant Chamber

description: Demonstration tests were conducted with two different direct field acoustic test methodologies in current practice as well as with a reverberant chamber. The same acoustic specification and small-scale test article were used for all three test approaches, and the same high bay test space was used for both direct field test methodologies. The direct field acoustic tests were conducted by their respective vendors, each providing their own sound production and control equipment and using their current preferred practice for control methodology. Acoustic field measurements were made by the Jet Propulsion Laboratory using a microphone array arranged in a 5 x 5 grid with 8-inch spacing placed in various locations and orientations around the acoustic field. For each test approach, the generated acoustic field was evaluated using metrics including comparison to specified test levels, spatial variability and coherence. Test article acceleration responses were also measured for comparison. This paper provides a summary description of the tests, salient results from each of the tests with respect to the various evaluation metrics, with a particular emphasis on comparison of the direct field test approaches to the reverberant chamber test as a baseline approach.

title: Robust Differential Correction Using Screens and Targets

description: Differential correction methods often focus on rapid convergence using linearization methods that sometimes require human interactions to address any failures in the process. In previous work, we introduced the first step of targeting in an overall geometric approach to differential correction that focuses on the robustness of convergence. Here, we explore different avenues for completing the differential correction process using a combination of screens and targets with an optimization approach using a cost function. Example scenarios are implemented in the circular restricted three-body problem, and the convergence process is summarized.

title: Solid Underconstrained Multi-Frequency (SUM) Deployable Antenna: Built, Measured, and Deployed to Tens of Microns

description: The Solid Underconstrained Multi-Frequency (SUM) antenna is a new deployable reflector architecture developed for operation at 240 GHz, where solid apertures require sub-63-micron root-mean-square (RMS) surface accuracy to meet λ/20 performance. SUM employs rigid carbon-fiber composite segments guided into position by high-strain rods and precisely seated using kinematic mounts, enabling an under-constrained deployment sequence that decouples actuation from final alignment. Testing has demonstrated deployment repeatability better than 10 microns and composite surface fabrication accuracy near 20 microns RMS, with assembled reflectors meeting the allocated layup and assembly portions of the error budget. Remaining challenges are dominated by thermal deformation and limitations in surface metrology, indicating that improved thermal-control strategies and higher-precision measurement systems will be required to close the final margin for flight. The reflector stows within a compact 0.42-m³ volume and deploys to a 2.4-m aperture, enabling high-frequency solid-surface antennas for ESPA-class spacecraft. This paper presents the SUM architecture, fabrication and assembly methods, deployment and layup accuracy results, and the full surface error budget demonstrating SUM’s potential for next-generation Earth science and communications missions.

title: Rotor-to-Rotor Interference Modeling for Flight Dynamics Analysis of a Mars Hexacopter Concept

description: Characterization of rotor-to-rotor wake interactions and their influence on flight dynamics is an important step toward advancing control system design and evaluating the performance of next-generation Mars multirotors. In this work, a Viscous Vortex Particle Method (VVPM) is utilized to generate rotor-on-rotor interference data for the Chopper Mars Helicopter platform, a large-scale hexacopter concept designed to be capable of carrying payload and pursuing independent science tasks. A reduced-order model compatible with finite state dynamic inflow is derived from the database. Interpolation strategies for continuous look-up are evaluated, with Gaussian Process Regression providing up to 20% improvement in prediction accuracy over linear interpolation of the interference data, although its scalability is limited by the large number of output channels. The interference model is implemented in HeliCAT, the flight dynamics analysis framework used for the Ingenuity Mars Helicopter, to assess the impact of rotor-on-rotor interference on trim, open-loop response and key stability derivatives. For Chopper, the first-order impact of rotor-rotor interaction on flight dynamics in hover is small, but with an observed increased pitch and roll damping. In forward flight, on-axis bare airframe responses exhibit attenuation at the lower frequencies due to interference, and increased sensitivity of the pitch response to vertical perturbations in cruise. Finally, a real-time closed-loop simulation is performed with and without the interference model to assess the impact on rotor power during a representative science mission flight trajectory on Mars, showing that total increase in mechanical shaft power due to multirotor wake interactions does not exceed 5% throughout the flight.

title: Law Indexes: New York

description: As part of efforts to expand the Local Geohistory Project, which aims to educate users and disseminate information concerning the geographic history and structure of political subdivisions and local government, this repository has been created to disseminate law index data for the State of New York. This index currently covers unconsolidated laws from 1778 through 1919.
The unconsolidated laws contain private, special, and local laws, which often concern one or several individuals, entities, or localities, unlike consolidated laws, which often apply to all similarly situated individuals, entities, and localities within a jurisdiction. Prior to the 20th century, unconsolidated laws were often the primary method used to alter municipal and county boundaries and forms of government in New York.
The data is released as individual tab-separated values (TSV) files by volume. The Detail column may contain additional Prefix information that is repeated from prior entries.
The Source Works omit amendatory acts, and were intended to be used in conjunction with the chronological Statutory Record of the Unconsolidated Laws.
This repository does not contain the full text of the laws, nor does it currently contain links to the full text. Because the index was created using OCR technology, it may contain uncaptured errors.
This is not an official publication of the State of New York or any of its instrumentalities, and is not affiliated with or endorsed by any government agency at any level.

title: Data from: Disentangling the relative roles of biased colonization and in situ evolution in driving the island syndrome in <em>Coprosma</em> (Rubiaceae)

description: The island syndrome can be defined as a suite of predictable and
 consistent similarities among island organisms. In plants, it can result
 from processes of biased colonization and/or in situ evolution. Despite
 recent progress in identifying its components, the relative contributions
 of these processes remain unclear. Here, I disentangle and quantify the
 relative roles of these processes in driving morphological change in
 Coprosma, a plant genus widespread across the Pacific. First, I amassed
 data for two morphological traits and tested for correlated evolution
 between morphology and insularity. I then used phylogenetic comparative
 methods and directed network models to determine whether possessing larger
 leaves and/or stature favoured island colonization, whether these
 similarities are exclusively the product of in situ evolution, or both.
 Results indicate that large-leaved ancestors were favoured during island
 establishment, while both leaf size and stature consistently increased on
 islands as a result of in situ evolution. Overall, this study provides a
 framework to distinguish between biased colonization and in situ
 evolutionary processes in island plants.
