title: Inferring the Linkage of Sea Surface Height Anomalies, Surface Wind Stress and Sea Surface Temperature with the Falling Ice Radiative Effects Using Satellite Measurements and Global Climate Models

description: This study attempts to infer the linkage of sea surface height anomaly (SSHA), frozen hydrometeors, oceanic mixed-layer depth (MLD), surface wind stress (TAU) and sea surface ocean temperature (SST), using satellite measurements from observations and global climate modeling focusing on the cloud radiative effects over the Pacific Ocean. We use CESM1-CAM5, one with the falling ice (snow) radiative effects (FIREs-on) on (SON) and without FIREs-off (NOS) under CMIP5 historical run. The data from obs4MIPs monthly data for SSH, ERSST for SST, CloudSat-CALIPSO frozen hydrometeors, QuickSCAT for TAU satellite measurements are used as references. The seasonal and annual mean spatial patterns of SSHA difference between NOS and SON are tightly linked to the spatial pattern differences in MLD, SST and TAU over the whole domain, in particular, over south Pacific oceans. Compared with NOS, SON simulates significant improved seasonal and annual mean SSHA associated with improved sea surface temperature (SST), surface wind stress (TAU) over the trade-wind areas. In SON, the simulated mean absolute bias of SSHA over the subtropical and tropical Pacific is reduced (up to 35%) against NOS relative to observations. Compared with CMIP5 models, their ensemble mean absolute biases of SSHA show similarities to NOS mainly over the south Pacific Ocean. Despite the biases of SST and SSHA over the south and north flanks of the equator in SON, the seasonal variations of improved SSHA are closely related to those of TAU and SST resulting from the FIREs; that is, higher SSHA and deeper MLD are associated with weaker TAU and warmer SST changes and vice versa.

title: Experience and Lessons Learned from Open Sourcing NASA AMMOS’s Mission Control Software

description: The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) sponsors the Advanced Multi-Mission Operations System (AMMOS), which is a set of tools and services that provide reliable, reusable, and repeatable space operation capabilities to as many NASA missions as possible. AMMOS supports NASA’s goal of achieving greater science at lower costs. Mission Control System (MCS) is one of the four functional elements under NASA AMMOS, and it includes mission-proven software such as the AMMOS Mission Data Processing and Control System (AMPCS). The Multimission Ground Systems and Services (MGSS) Program at the NASA Jet Propulsion Laboratory (JPL) manages the NASA AMMOS. To broaden their reach and increase their adoption at other NASA centers and partner organizations, MGSS is releasing the following set of NASA AMMOS mission control software as open source, as early as June 2023: AMPCS, Mission Control Web Service (MCWS), Open Mission Control Technologies (Open MCT) for MCWS, Spacecraft Language Interpreter and Collector II (SLINC II), Command Translation Subsystem (CTS), Telecommand Utilities (TCU), and Standards Support System (SSS). There are several challenges in open sourcing this software set. The code, its documentation, and accompanying data contain controlled unclassified information that cannot be made public. Open sourcing must also comply with United States export control regulations. The software set has dependencies on other proprietary software that are not publicly available. The budget to perform the open sourcing work is small. None of the software set’s maintainers have any previous experience hosting and running an open-source project or managing communities for such projects. A team of 6 software engineers (1.4 full-time equivalents, or FTE) at JPL and NASA Ames Research Center (ARC) has been employing techniques to remove or replace the software set’s non-releasable code, documentation, data, and private external dependencies. They are also refactoring the source structure and documentation to follow open-source software style conventions. Open sourcing NASA’s premier mission control software set will encourage more centers and partners to use it for their future space missions. They will gain the ability to extend the software themselves to satisfy their unique mission needs, inspect problems directly when they encounter them, audit its cybersecurity, repair defects quickly, and benefit from the greater open-source community support to use the product better. NASA AMMOS is also expected to benefit from this future community, as the latter contributes code and improvements to the software.

title: Cybersecurity Analysis Challenges of Legacy Ground Data System

description: Most of the legacy space missions operated on a decades-old Ground Data System (GDS). Unfortunately, decades ago, IT security design is done separately from the design of GDS' mission operational capabilities. This incoherent practice left many security vulnerabilities without notice in an extended mission phase mission. Identifying the vulnerabilities that may exist in a legacy GDS becomes urgent. Unknown threats can exploit the mission operation without knowing the cybersecurity vulnerabilities. The threats can affect one or all of the GDS capabilities. For example, tampering with spacecraft commands, unauthorized use of a system to create unwanted science products, and disrupting a command uplink. The consequence can cause a mission to end with losing the spacecraft. However, it is a daunting task to perform a cybersecurity risk assessment on a decades-old system.

title: Deep space optical communications technology demonstration

description: The National Aeronautics and Space Administration’s (NASA) Deep Space Optical Communications (DSOC) technology demonstration is ongoing following launch of NASA’s Psyche spacecraft, in October 13, 2023. The DSOC flight laser transceiver (FLT), integrated to the Psyche spacecraft, is implemented to acquire a 1064 nm laser beacon from earth, and return a 1550 nm serially concatenated pulse position modulated (SCPPM) signal. The FLT consists of: a 22 cm diameter unobscured aperture, optically coupled to a 4 W average power laser and an assembly of actuators, sensors, electronics and software. The multi-beam 1064 nm laser beacon with an average power of 7 kW, integrated to the Optical Communications Telescope Laboratory (OCTL) near Wrightwood, CA and equipped with necessary accessories, serves as the Ground Laser Transmitter (GLT). A photon-counting receiver integrated to the Palomar Observatory, Hale telescope (operated by Caltech Optical Observatories) constitutes the Ground Laser Receiver (GLR), for decoding information sent from space. A DSOC Mission Operations System (MOS) co-located with the Psyche Project Mission Support Area (MSA) at the Jet Propulsion Laboratory (JPL), coordinates DSOC technology demonstration activities. In this paper a system overview, mission plan, operations architecture are described. Early results that include end-to-end link operations at the maximum designed downlink data-rate of 267 Mb/s from 0.37 astronomical units (AU) and other initial measurements are presented.

title: Exomoon Phase Curves: Toroidal Exosphere Simulations of Exo-Ios Orbiting 8 Exoplanets in Alkali Spectroscopy

description: Toroidal atmospheres and exospheres characterized at exoplanets may be fueled by volcanically- active exomoons, often referred to as exo-Ios. We study the neutral outgassing and volatile evolution of a close-orbiting, evaporating satellite at eight candidate exoplanet-exomoon systems WASP-49,-96,-69,-17 b, XO-2N b, HAT-P-1 b, HD-189733 b, and HD-209458 b by developing a 3-D test-particle Monte-Carlo simulation, SERPENS. The module is cou- pled to dishoom, approximating the minimum mass-flux needed to reproduce observa- tions of alkali line profiles identified in dozens of transmission spectra. We focus on sput- tered neutral sodium, limited by photoionization and radiative effects. By considering Earth-, Io-, and Enceladus-like masses, we systematically simulate the imprint of a non- hydrostatic medium (characteristic of volcanic exospheres) in density and velocity space using a novel Delaunay tesselation field estimator algorithm. Our results demonstrate how exomoons can considerably modulate gas density observations probed near exoplanet transit, depending on the orbital phase of the putative satellite at the time of observa- tion. The density evolution, therefore, manifests on orbital timescales as ‘exomoon phase curves’ from shadow to occultation. We find two regimes of density evolution, charac- teristic of a: (A) localized cloud and (B) an azimuthally symmetric exoring/torus, de- generate with an exoplanet atmosphere, ranging from ∼109.5±0.5 cm−2 to ∼1015±0.25 cm−2 at our leading candidate WASP-69b I. In certain orbital architectures, the smallest evap- orating satellite mass surprisingly generates the brightest sodium signal, fueling optimism for discovering photometrically-indiscernible rocky exomoons. We suggest long baseline monitoring of alkali and SO2 systems in spectroscopy to search for the temporal and spa- tial variability predicted here.

title: Next Generation High Stability, Long-Life Mercury Ion Clocks for Ground and Space Applications

description: With its 40+ year history, mercury ion clocks have demonstrated excellent performance in both ground and space applications. The microwave-based technology has resulted in observations of mercury clocks with relative frequency stability ranging from nearly 1E-14/1E-16 (measured at 1s/1E4s, respectively) [Tjoelker et al. (1996), Dick et al. (1998), Burt et al. (2008)] in clocks with a 200L volume to 1E-11/1E-13 (measured at 1s/1E4s, respectively) in a 1L volume [Hoang et al. (2023)]. A recently completed space-based mercury ion clock technology demonstration mission (NASA Deep Space Atomic Clock (DSAC) [Tjoelker et al. (2016), Burt et al. (2021)]) had a relatively compact form factor (∼19L) and proved the ability of the technology to support 5 year life with a fractional frequency stability from 2E-13 to 2E-15 (measured at 1s/1E4s, respectively) and long term drift &lt;3E-16/day. This low drift, 1-2 orders of magnitude lower than other currently operating space clocks based on other principles, illustrates this technology’s utility for applications requiring autonomy. The relatively long clock life along with its low sensitivity to ambient temperature and magnetic field makes the device promising for future critical space (e.g. GNSS) and ground (e.g. NASA Deep Space Network) applications. We here report on targeted R&D efforts following the DSAC mission towards the development of a manufacturable clock prototype intended for future ground and flight applications that require hydrogen maser level stability performance and reliability. We present the clock concept, which is designed to reduce the clock’s size, weight and power consumption (SWaP) while still maintaining or even improving performance. We developed a new compact quadrupole ion trap configuration supporting long clock transition coherence time observations exceeding similar parameters of DSAC by an order of a magnitude. Lifetime and reliability considerations of the clock’s critical components will also be addressed. Finally, the importance of the local oscillator utilized in the clock is illustrated and a possibility of implementation of a compact mercury clock with 4E-15 to 2E-16 stability (measured at 1s/1E4s, respectively) is discussed.
