title: Flight system acquisition, tracking, and pointing results from the Deep Space Optical Communications technology demonstration

description: NASA’s Deep Space Optical Communications (DSOC) Project, implemented by the Jet Propulsion Laboratory (JPL), utilized a novel acquisition, tracking and pointing (ATP) approach to successfully complete the first year of its technology demonstration, delivering high-rate optical downlink from deep space distances of 0.1 to 2.7 astronomical units (AU). The downlink laser was initially pointed with spacecraft assisted coarse pointing of the DSOC Flight Laser Transceiver (FLT) boresight towards the DSOC Ground Laser Transmitter (GLT). FLT sensors and actuators searched out the spacecraft pointing uncertainty region to acquire and track the GLT uplink optical beacon as a reference signal for platform stabilization. The beacon-assisted controller achieved sub-microradian-level downlink pointing control, implemented using on-board computed point-ahead angles that were equivalent to many downlink laser beam-widths. In this paper we describe the DSOC ATP architecture and associated algorithms, summarize the operational performance results to date, and touch upon lessons learned and future avenues for improvement.

title: Review and prospects of hot exozodiacal dust research for future exo-Earth direct imaging missions

description: Hot exozodiacal dust is dust in the innermost regions of planetary systems, at temperatures around 1000 K to 2000 K, and commonly detected by near-infrared interferometry. The phenomenon is poorly understood and has received renewed attention as a potential risk to a planned future space mission to image potentially habitable exoplanets and characterize their atmospheres (exo-Earth imaging) such as the Habitable Worlds Observatory (HWO). In this article, we review the current understanding of hot exozodiacal dust and its implications for HWO. We argue that the observational evidence suggests that the phenomenon is most likely real and indeed caused by hot dust, although conclusive proof in particular of the latter statement is still missing. Furthermore, we find that there exists as of yet no single model that is able to successfully explain the presence of the dust. We find that it is plausible and not unlikely that large amounts of hot exozodiacal dust in a system will critically limit the sensitivity of exo-Earth imaging observations around that star. It is thus crucial to better understood the phenomenon in order to be able to evaluate the actual impact on such a mission, and current and near-future observational opportunities for acquiring the required data exist. At the same time, hot exozodiacal dust (and warm exozodiacal dust closer to a system’s habitable zone) has the potential to provide important context for HWO observations of rocky, HZ planets, constraining the environment in which these planets exist and hence to determine why a detected planet may be capable to sustain life or not.

title: The Deep Space Optical Communications (DSOC) Flight Terminal

description: NASA’s Deep Space Optical Communications (DSOC) Project, implemented by the Jet Propulsion Laboratory (JPL), has successfully completed the first year of its technology demonstration, delivering high-rate optical downlinks for the first time from deep space over spacecraft distances ranging from 0.1 to 3 astronomical units (AU). The heart of the flight terminal is an essentially free-floating 22 cm telescope and photon-counting camera, mounted on a platform that is steered by Lorentz-force actuators. The hardware also includes a 4 Watt transmit laser and associated electronics. The instrument software and firmware algorithms detect and track a modulated optical uplink beacon, decode data modulated on that beacon signal, point the downlink laser, and encode pulse position modulated (PPM) data for the optical downlink. These hardware elements are described, along with the firmware and software signal processing algorithms. The concept of operations for the flight terminal is also described.

title: Thermal Structure and Composition of Jupiter’s Great 2 Red Spot from JWST/MIRI

description: JWST/MIRI’s MRS mode, utilising 4 IFUs (4.9 – 27.9 μm) observed Jupiter’s Great Red Spot (GRS) in July and August 2022, tracking the horizontal and vertical distributions of temperature, aerosol and compositional gradients across the vortex on timescales longer than the GRS rotation rate of 4 days. This is one of the brightest targets observed by MIRI and algorithms were successfully used to address the challenges of wavelength calibration, desaturation, removal of spatial artefacts as well as navigating this dataset. Retrievals from the 7.30 – 10.75 μm range, presented alongside a suite of supporting visual and near-infrared observations were used to map the distributions of temperature, ammonia, phosphine and aerosols. A series of stratospheric hot-spots were discovered to be co-moving with the longitudinal drift of the GRS, potentially the consequence of atmospheric perturbations propagating upwards into the stratosphere. Both temperature and ammonia distributions within the GRS consistently displayed north-south asymmetries, most likely the result of the GRS tilting in the zonal direction. Ammonia was shown to be depleted above the GRS, indicating that it may be forced to condense due to the low temperature anomaly within the vortex. Meanwhile, the phosphine distribution within the GRS was shown to be proportional to integrated aerosol opacity, suggesting that the excess aerosol layers above the GRS may play a role in maintaining the phosphine population above the GRS by providing shielding from the UV light that would normally photolyse and remove this molecule. A small storm was captured north-west of the GRS in August that also displayed a phosphine excess. This would be a suitable location to search for deep molecular species in future studies. Finally, thermal wind and Brunt-Va¨is¨ala¨ frequency within the GRS is mapped in the vertical direction in unprecedented detail, indicating consistency with the despinning of the anticyclonic winds with altitude and suggesting revised depths for the location of the cloud-tracked winds in the visible for Hubble and the near-infrared for NIRCam.

title: The Structure of the Molecular Envelope of the Ring Nebula (NGC 6720

description: We present the first interferometric imaging of molecular line emission from the Ring Nebula, NGC 6720, in the form of Submillimeter Array (SMA) observations of CO J = 2 → 1 emission. The SMA 12 CO(2–1) mapping data, with ∼3′′ spatial resolution and 2 km s−1 velocity resolution, provide an unprecedentedly detailed, 3D view of the Ring’s clumpy molecular envelope. The morphoogy of the velocity-integrated SMA 12 CO(2–1) image closely resembles those of near-IR H2 and PAH emission in JWST/NIRCam imaging of NGC 6720, with the molecular gas forming a geometrically thin layer surrounding the ionized gas imaged by HST and JWST. A simple, geometrical model of the 12 CO(2–1) data shows that the intrinsic structure of NGC 6720’s molecular envelope closely resembles a truncated, triaxial ellipsoid that is viewed close to pole-on, and that the dynamical age of the molecular envelope is ∼6000 yr. The SMA 12 CO(2–1) data furthermore reveal that filamentary features seen projected in the Ring’s interior in JWST imaging are in fact fast-moving polar knots or bullets with radial velocities of ±45–50 km s−1 relative to systemic, and that the hot progenitor star remnant is positioned at the precise geometric center of the clumpy, ellipsoidal molecular shell. We assert that the Ring’s molecular envelope was formed via a relatively sudden, AGB-terminating mass ejection event ∼6000 yr ago, and that this ellipsoidal envelope was then punctured by fast, collimated polar outflows resulting from interactions between the progenitor and one or more companion stars. Such an evolutionary scenario may describe most molecule-rich, “Ring-like” planetary nebulae.

title: Long-term global measurements of methanol, ethene, ethyne, and HCN from the Cross-track Infrared Sounder

description: Volatile organic compounds (VOCs) play an important role in modulating the atmosphere’s oxidizing capacity and affect tropospheric ozone, carbon monoxide, formaldehyde, and organic aerosol formation. Space-based observations can provide powerful global information to advance our knowledge of these processes and their changes over time. We present here the development of new retrievals for four key VOCs (methanol, ethene, ethyne, and HCN) based on thermal infrared radiance observations from the satellite-borne Cross-track Infrared Sounder (CrIS). We update the Retrieval of Organics from CrIS Radiances (ROCR) algorithm developed previously for isoprene to explicitly account for the spectral signal dependence on the VOC vertical profile shape, and apply this updated retrieval (ROCRv2) to derive column abundances for the targeted species across the full Suomi-NPP CrIS record (2012-2023). The CrIS data are well-correlated with ground-based Network for the Detection of Atmospheric Composition Change (NDACC) retrievals for methanol (r=0.77-0.84); HCN and ethyne exhibit lower correlations (r=0.36-0.44 and 0.56-0.65, respectively) with an apparent 40% CrIS/NDACC disparity for ethyne. The results reveal robust global distributions of the target VOCs from known biogenic, biomass burning, and industrial source regions, and demonstrate the impact of anomalous events such as the 2015-2016 El Niño. They also highlight the importance of accurate vertical profile constraints when evaluating and interpreting thermal infrared data records. Initial comparisons of the CrIS observations to predicted VOC distributions from the GEOS-Chem chemical transport model point to large uncertainties in our current understanding of the atmospheric ethene budget as well as to underestimated HCN, ethyne, and methanol sources.
