title: Observations of Water Frost on Mars with THEMIS: Application to the Presence of Brines and the Stability of (Sub)Surface Water Ice

description: Characterizing the exchange of water between the Martian atmosphere and the (sub)surface is a major challenge for understanding the mechanisms that regulate the water cycle. Here we present a new dataset of water ice detected on the Martian surface with the Thermal Emission Imaging System (THEMIS). The detection is based on the correlation between bright blue-white patterns in visible images and a temperature measured in the infrared that is too warm to be associated with CO2 ice and interpreted instead as water ice. Using this method, we detect ice down to 21.4°S, 48.4°N, on the pole-facing slopes at mid-latitudes, and on any surface orientation poleward of 45° latitude. Water ice observed with THEMIS is most likely seasonal rather than diurnal. Our dataset is consistent with near-infrared spectroscopic data predictions by the Mars Planetary Climate Model. The water frost average temperature is 170 K, and the maximum temperature measured is 243 K, lower than the water ice melting point. We show that the melting of pure water ice on the surface is unlikely due to cooling by latent heat during its sublimation. However, 243 THEMIS images show frosts that are hot enough to form brines if salts are present on the surface. The water vapor pressure at the surface, calculated from the ice temperature, indicates a dry atmosphere in early spring, during the recession of the CO2 ice cap. When it sublimates, the frost acts as a vapor source that is wetter than the near-surface atmosphere, which stabilizes the subsurface ice.

title: Euclid. III. The NISP Instrument

description: The Near-Infrared Spectrometer and Photometer (NISP) on board the Euclid satellite provides multiband photometry and R & 450 slitless grism spectroscopy in the 950–2020 nm wavelength range. In this reference article we illuminate the background of NISP’s functional and calibration requirements, describe the instrument’s integral components, and provide all key properties. We also sketch the processes needed to understand how NISP operates and is calibrated, and its technical potentials and limitations. Links to articles providing more details and technical background are included. NISP’s 16 HAWAII-2RG (H2RG) detectors with a plate scale of 0: 003 pixel􀀀1 deliver a field-of-view of 0.57 deg2. Design drivers for NISP were to reach a limiting magnitude of 24.0ABmag in three photometric exposures of about 100 s exposure time, for point sources and with a signal-tonoise ratio (SNR) of 5. For spectroscopy, the design sensitivity is a SNR = 3:5 detection of an emission line with flux 2 10􀀀16 erg s􀀀1 cm􀀀2 in 3 560 s grism exposures at 1.6 µm (redshifted H) and a source with 0: 005 diameter. Our calibration includes on-ground and in-flight characterisation and monitoring of pixel-based detector baseline, dark current, non-linearity, and sensitivity, to guarantee a relative photometric accuracy of better than 1.5%, and relative spectrophotometry to better than 0.7%. The wavelength calibration must be accurate to 5Å or better. NISP is the state-of-the-art instrument in the near-infrared for all science beyond small areas available from HST and JWST – and an enormous advance from any existing instrumentation due to its combination of field size and high throughput of telescope and instrument. During Euclid’s 6-year survey of 14 000 deg2 extragalactic sky, NISP will be the backbone to determine distances of more than a billion galaxies. Its near-infrared data will become a rich reference imaging and spectroscopy data set for the coming decades.

title: JAXA 3-Way Doppler Support to Artemis I Mission

description: This paper presents a collaborative effort between NASA and JAXA to make 3-way Doppler data from JAXA tracking stations available to the Artemis 1 navigation team to improve orbit determination. The paper describes the system configuration and concept of operation of this capability. Testing effort at the three JAXA’s ground stations – the Uchinoura’s 20-m and 34-m antennas and Usuda’s 64-m antenna – are discussed. Both aspects of system testing are highlighted, first on the use of Artemis 1 recorded signal to ensure compatibility between ground and flight systems, and second on the tracking with the Lunar Reconnaissance Orbiter, as a substitute for Artemis before launch, to validate other key operational functions such as ephemeris processing, spacecraft tracking capability, data delivery, and interactions among multiple operational teams in different organizations. Results from actual support to Artemis 1’s Orion spacecraft in November-December 2022 are also presented.

title: 4TH BODY-INDUCED SECONDARY RESONANCE OVERLAPPING INSIDE UNSTABLE RESONANT ORBIT FAMILIES: A JUPITER-GANYMEDE 4:3 + EUROPA CASE STUDY

description: The overlapping of mean-motion resonances is useful for low or zero-propellant space mission design, but while most related prior work uses a planar CRTBP model, tours of multimoon systems require using resonances affected by two moons. In this work, we investigate Jupiter-Ganymede unstable 4:3 resonant orbits in a concentric circular restricted 4-body model for the Jupiter-Europa-Ganymede system. We show that despite their high order, secondary resonances between these orbits and Europa have a large effect, especially 11/34, 12/37, 23/71, 25/77, 34/105, and 35/108; we also find strong evidence that the associated resonant islands overlap. We then compute many of the new objects which appear inside the secondary resonances, which gives final confirmation of the secondary resonance overlap.

title: Validation of Korea Deep Space Antenna with NASA Spacecraft Tracking

description: This paper presents our effort in validating the capability andperformance of the first Korean deep space antenna (KDSA)that was built to support the country’s first lunar mission - theKorean Pathfinder Lunar Orbiter (KPLO) which is also knownas Danuri. Prior to KPLO launch, we leveraged on the NASAspacecraft – the Lunar Reconnaissance Orbiter (LRO) andJuno - currently in flight to support this testing effort. The testswere conducted on a non-interference basis. These testshelped validate the KDSA’s key functions such as ephemerisprocessing, antenna pointing, spacecraft signal acquisition anddemodulation under realistic Doppler signal conditions,generation of tracking data output, etc. System performancemetrics such as antenna gain/temperature (G/T) was alsoestimated from these tests.

title: The Q-band (43 GHz) Celestial Reference Frame observed in 2021

description: Our Q-band (43 GHz) celestial reference frame, based on three dual-polarization VLBA sessions from 2021, has 428 sources and 67 thousand observations. The primary goal of these sessions was to compare the structure of the active galactic nuclei (AGN) observed at Q-band (43 GHz) to S, X, and K-bands (2.3, 8.4, and 24 GHz) using nearly concurrent VLBA sessions. The solution presented here was made with the VieVS software on February 09, 2024. Median formal precisions are 203 μas in α cosδ and 353 μas in δ. This Q-band frame is based solely on the all northern geometry of the VLBA. As a result, sky coverage is limited to declinations above -45 deg and precision tends to decrease as one moves South. We are exploring the potential to add Q-band VLBI observations using the Korean tri-band (K, Q, W-band) system. In the far south, we are exploring the baseline from Mopra, Australia to the CART 40m, Argentina. The prospects for future improvements are bright with the aforementioned potential for adding new stations as well as plans for proposing for more Q-band time on the VLBA, and the planned VLBA upgrade from 4 to 8 Gbps data rat

title: Geodetic analysis of K-band VLBI observations until 2024.0

description: We perform a geodetic analysis of K-band (24 GHz) VLBI sessions from May 2002 until September 2023. For this study, we run a global solution by adjusting the time independent parameters from the K-band and S/X sessions (1979.5–2024.0) through a single inversion of all observations. Therefore, we are able to provide the positions of the non-geodetic antennas KVNUS, KVNYS and Mopra for the reference epoch 2015.0 with their linear velocity, which are aligned to the ITRF2020. Formal errors of the position component estimates are below 0.8 cm for the KVN antennas and about 2 cm for Mopra. The components of station linear velocity were estimated with formal errors 0.1 mm/y for KVN antennas and lower than 0.5 mm/y for Mopra. Furthermore, we focus on the potential of the K-band VLBA network for Earth orientation monitoring. We present the accuracy of the Earth orientation parameters computed from the K-band sessions with respect to the a priori IERS values and compare them with the accuracy obtained from the traditional S/X observations.

title: SOLID UNDER-CONSTRAINED MULTI-FREQUENCY (SUM) DEPLOYABLE ANTENNA

description: To enhance predictive weather modelling, small satellite constellations equipped with multi-frequency deployable antennas (ranging from 10 GHz to 600 GHz) become imperative. Existing single-satellite methodologies fail to capture the complete lifecycle of storms, which is crucial for monitoring key observables assessed by atmospheric radars, microwave sounders, and differential absorption radars. A novel deployable antenna is essential to effectively monitor these phenomena with a satellite constellation, as current small satellite deployable antennas are limited to frequencies below 70 GHz. The Solid Under-Constrained Multi-Frequency (SUM) Deployable Antenna, supported by the innovative Starburst deployable architecture, presents a cost-effective solution for high-frequency, wide-bandwidth, offset-fed deployable reflectors, thereby opening new avenues in Earth Science applications. The concept discussed here is a 2-meter deployable antenna, with a deployed surface accuracy of 60 microns, to operate from 2 GHz to up to 240 GHz.

title: TP-DejaVu: Combining Operational and Declarative Runtime Verification

description: Runtime verification (RV) facilitates monitoring the executions of a system, comparing them against a formal specification. A main challenge is to keep the incremental complexity of updating its internal structure, each time a new event is inspected, to a minimum. There is a tradeoff between achieving a low incremental complexity and the expressive power of the used specification formalism. We seek an RV tool that allows us to specify properties of executions that include data, with the possibility to apply arithmetic operations and comparisons on the data values. In order to be able to apply efficient RV for specifications with these capabilities we combine two RV methodologies: the first one is capable of performing arithmetic operations and comparisons based on the most recent events; the second is capable of handling many events with data and relating between events that occur at arbitrary distance in the observed execution. This is done by two phase RV, where the first phase makes the arithmetic calculations and comparisons and feeds the second phase with augmented events for further processing. This is implemented as a tool called TP-DEJAVU (where TP stands for two phase), which extends the DEJAVU tool.

title: Dynamics of Gyroscopic Stabilized Tether Satellite System in LEO

description: This paper studies the dynamics of a tether satellites system composed of two satellites controlled using a gyroscopic stabilization. This configuration is particularly convenient for remote sensing applications, guarantying a continuous oscillation in the cross-track direction that could be beneficial for synthetic aperture radar missions. The stabilization is obtained by spinning the system about a vector tracing a circumference on the radial along-track plane during the orbit. The rotational motion of the system causes a centrifugal force on the satellites, that provides the tension in tether needed to keep the formation in shape. The behavior of this tethered system in low Earth orbit is analyzed introducing the dynamic equations of relative motion centered in an orbiting reference frame. The equations model the three-dimensional multi- body dynamics of the system in this environment, considering all the most important external perturbations. This architecture is analyzed by extensive numerical simulations, which provided insight into the gyroscopic effects on the systems and the effectiveness of this stabilization. Finally, the effect of different rotational speeds has been analyzed, and the scalability of the system has been considered.
