title: Development of radar and optical tracking of near-Earth asteroids at the University of Tasmania

description: We detail the use of the University of Tasmania’s (UTAS) optical and radio telescopes to conduct observations of near-Earth asteroids from 2021 to 2024. The Canberra Deep Space Communication Complex transmitted a radio signal at 7159.45 MHz, with the radar echo detected by the UTAS radio telescopes. The method of accounting for the Doppler shift between the stations and the near-Earth object will be described so as others could implement a similar program. We present our results, with confirmed detections of 1994 PC1 and 2003 UC20 asteroids using the Hobart and Katherine 12-meter antennas, demonstrating the feasibility of using small radio telescopes for these observations. Additionally, the recently upgraded Ceduna 30 m antenna was used to detect 2024 MK. Data collected from other observatories, such as Tidbinbilla, as well as the UTAS radar tracking of the moon will also be presented in the context of demonstrating the means of applying these Doppler corrections and the accuracy of each method. Optical observations conducted in this period will also be detailed, as they complement radar observations and aid in refining the orbit parameters.

title: New Inflight Calibration of OCO-3’s A-Band for Version 11 Products

description: The Orbiting Carbon Observatory-3 (OCO-3) instrument, operated from the International Space Station, was launched on May 4th, 2019. Its primary objective is to provide high precision estimates of the column-averaged dry-air mole fraction of carbon dioxide (XCO2) and solar-induced chlorophyll fluorescence. It consists of three long-slit imaging spectrometers that provide high resolution spectra in three infrared bands. The shortest wavelength one, named A-Band, is centered at 0.765 μm and characterized by numerous absorption lines of molecular oxygen. Throughout the mission, this band has undergone important changes in instrument response related to contamination of the focal plane array. One way contamination buildup affects OCO-3 data is by imparting an S-like shape to the observed spectra, which cannot be characterized and corrected through analysis of data from the on-board calibrator alone. In Version 10, this artifact manifested itself as a slow drift of XCO2, from February 2020 to January 2021, and required an additional post-retrieval bias correction. In the latest collection, Version 11, OCO-3’s inflight calibration algorithm for the A-Band was augmented to correct this artifact using clear ocean scenes to derive the spectral shape of changes in instrument response. This drastically improved the shape of spectral residuals between observed and forward modeled radiances and also significantly reduced the slow XCO2 drift observed in Version 10.

title: Freestanding Metal-Mesh Bandpass Filters with Wide Apertures for 2-5 THz

description: We report on the design and experimental characterization of metal-mesh bandpass filters for the 2 – 5 THz range. These filters are 3 - 5 μm thick freestanding copper films with a periodic array of either diamond-shaped or circular apertures. The simple aperture design enables robust engineering of the bandpass profile, achieving high peak power transmission (&gt; 90 %) with a relatively narrow 3-dB bandwidth (5 - 15 %) across a wide THz frequency range (2 – 5 THz). Based on our numerical simulation results, we provide simple design equations for the filter design and experimentally demonstrate the bandpass filters with diamond-shaped apertures at 1.9 THz, 2.5 THz, and 4.7 THz. The measured transmission properties - center frequency, 3-dB bandwidth, and peak power transmission - agree well with the designed behavior. These filters are compatible with cryogenic operation and offer a cost-effective, high-performance solution for the THz bandpass filters in the 2-5 THz range.

title: Experimental Study on the Effects of Ambient Light on the Precision of Short-Range Near-Infrared LiDAR Systems

description: This work investigates the influence of ambient light noise on the performance of an 850 nm single-point light detection and ranging (LiDAR) system, specifically focusing on targets with varying reflectivity and range. A commercial LiDAR module was used, in conjunction with six distinct specimens, to collect and analyze spatial-temporal data over a measurement range of up to 4 meters. The spatial-temporal analysis of quasi-static experimental data reveals that luminous intensity and range critically affect LiDAR accuracy. At the same time, reflectivity consistently impacts LiDAR measurements irrespective of their magnitude but varies with material type. The relative error in measurement, reflectivity of material, and luminous intensity of the light noise exhibit near-normal distributions with asymmetrical tails. Statistically significant differences between the distributions of relative error, reflectivity, and luminous intensity highlight the complex interactions influencing LiDAR performance. These findings offer essential insights for the design and optimization of LiDAR systems, ensuring accurate environmental sensing under variable ambient light conditions, and they affirm the possibility of developing transferable models.

title: Electron Density in Io’s Alfvén Wing Observed via Radio Occultation with Juno

description: Juno performed close flybys of the innermost Galilean moon, Io, in December 2023 (I57) and February 2024 (I58). During these flybys, the radio link connecting the Juno spacecraft to Earth observing stations of NASA’s Deep Space Network propagated through the Alfvén wing, a magnetospheric feature in which plasma accumulates between Io and Jupiter. The radio link is sensitive to the elevated electron densities in the Alfvén wing. A direct measurement of the total electron content was made by a linear combination of Juno’s X-band and Ka-band downlink frequencies. Two different approaches were used in inverting the measurements into electron densities which assume different electron density distributions within the Alfvén wing. The maximum electron densities observed in the Alfvén wing were 20,500-27,000 cm-3 on I57, in the northern Alfvén wing, and 15,300-31,000 cm-3 on I58, in the southern Alfvén wing.

title: An Adaptive, Statistical Multiscale Phase Unwrapping Approach to Process Large Swath Interferograms

description: This study investigates the potential of a statistical-based, adaptive approach to unwrapping sequences of differential synthetic aperture radar (SAR) interferograms that cover a large swath of the terrain. The proposed method adopts a multiscale decomposition strategy to identify efficiently and then process sets of coherent points at different spatial scales. The coherent point selection process is performed considering the statistical properties of the stack of wrapped multi-looked SAR interferograms generated at various scales. Overall, the adopted procedure allows automatically recognising the areas in large swath interferograms where significant and reliable phase changes occur while moving from neighbouring spatial scales. Over these regions, multiscale phase unwrapping (PhU) operations are performed efficiently, with a computational improvement and without losing significant information. To this aim, the implementation of a conditioned space-time PhU scheme that operates sequentially at different spatial grids is detailed. Then, the unwrapped interferograms are inverted to generate ground displacement time series through advanced multi-temporal interferometric SAR (MT-InSAR) approaches, recovering information at different scales (from local to regional/continental). Experimental results have been obtained by applying the developed scheme to large-swath SAR datasets collected at C band by Sentinel-1 sensors. The results demonstrate the feasibility and soundness of the developed multiscale PhU method.

title: Non-traditional data to inform modern climate science

description: The global climate is changing rapidly, with cascading impacts across the world. Even though the modern instrument-based record of Earth observations reflects decades of critical work, multi-century time series may be required to understand and forecast key elements of Earth system dynamics. Here, we review the potential uses of non-traditional climate data records – observations reported without using modern instruments or standardized measurement protocols – to identify climate and ecosystem dynamics that predate modern methodologies and tools. We compile a list of diverse datasets collected over more than 500 years, including landscape paintings, sea lore, and animal migration data. This initial review presents opportunities for further investigation to reconstruct past climate or to use non-traditional records to complement modern instrument methods.

title: Dirac’s Large Number Hypothesis: An Ongoing Quest for Correlations Between the Infinitesimal and the Infinite

description: Dirac's Large Number Hypothesis (LNH), proposed in 1937, has captivated the scientific community with its exploration of profound correlations between cosmic and atomic scales. This hypothesis delves into the intricate interplay between the infinitesimally small and the vastly large, offering potential insights into the fundamental nature of the universe. As we continue to uncover the mysteries of the cosmos, the LNH oscillates on the precipice of scientific acceptance—neither fully validated nor entirely dismissed. In this paper, we embark on a comprehensive journey through Dirac's LNH, shedding light on its theoretical underpinnings, its implications for universe models, and its resonance with the Anthropic Principle. We delve into the possibilities of variable gravitational constants and continuous mass creation, inviting further exploration into the intricacies of our cosmic symphony. By embracing the ongoing quest for understanding, we endeavor to unravel the profound harmonies that connect the infinitesimal with the infinite, contributing to the symphony of knowledge in theoretical physics and cosmology.

title: Contact Mechanics via FEM and BEM for Multibody Dynamics Modeling

description: Robotic systems and their mechanism assemblies are unprecedentedly leveraged in current NASA programs for on-orbit operations and space explorations in the solar system and its other planets, and the stellar spaces beyond. These robotic systems are operating in harsh and hostile environments which can potentially damage mission critical components and jeopardize mission success. It is well-known that high-quality multibody dynamics predictions of contact interaction loads are vital to achieve the optimal robotic and mechanism structural designs with reduced weight. It is also widely recognized that the well-established predictive methodology is one of the key approaches to accurately characterize contact modeling parameters for multibody dynamics predictions. This first portion of the paper focuses on deriving the contact coefficient and exponent, and the model cross validation of multibody dynamics contact loads via finite element nonlinear contact analysis. These finite element results are next compared to solutions from Hertzian contact theory and boundary element contact analysis. This comparison suggests that the boundary element method can provide an attractive approach to study a range of problems in contact mechanics. Interestingly, all these classical models show the location of peak effective stress to be inside the bodies, removed from the contact surface, yet surface failures often occur in such problems. To address this issue, a BEM-based size-dependent contact mechanics formulation is then presented utilizing couple-stress theory and results from a model problem are provided that predict a transition of the peak effective stress to the surface, depending upon the couple stress length scale material parameter.
