title: Statistics of electron-multiplying charge-coupled devices

description: EMCCDs are efficient imaging devices for low surface brightness UV astronomy. The large amplification allows photon counting, the detection of events versus non-events. This paper provides the statistics of the observation process, the photon-counting process, the amplification, process, and the compression. The expression for the signal-to-noise of photon counting is written in terms of the polygamma function. The optimal exposure time is a function of the clock-induced charge. The exact distribution of amplification process is a simple-to-compute powered matrix. The optimal cutoff for comparing to the read noise is close to a strong function of the read noise and a weak function of the electron-multiplying gain and photon rate. A formula gives the expected compression rate.

title: How well do present data constrain Ganymede's core magnetic field?

description: Ganymede is the only moon in our solar system known to have a large-scale intrinsic magnetic field, likely generated in the moon's metallic core. Initial analyses of Galileo spacecraft measurements concluded that Ganymede's intrinsic magnetic field is dominated by a magnetic dipole and that quadrupolar contributions are exceptionally weak. These findings have influenced the development of models for Ganymede's core dynamo over the past two decades. Recent magnetic data collected by the Juno spacecraft near Ganymede confirmed the original findings. Here, we reassess Ganymede's internal field contributions based on the magnetic measurements from close Galileo flybys of Ganymede (G1, G2, G7, G8, G28, G29), adding the recent Juno flyby. We use the same approach as previous studies but extend our analysis to higher spherical harmonic degrees to assess the range of magnetic field spherical harmonic models that fit the data. Our choice of spherical harmonic degrees is justified using a coefficient correlation analysis. We find that the limited spatial coverage of available Ganymede magnetic data precludes conclusions regarding quadrupolar strength, as we are able to construct spherical harmonic models for any source radius within Ganymede's range of likely core radii. Contributions from induced fields in Ganymede's oceans do not change our conclusions.

title: Formal Methods for Trusted Space Autonomy, Boon or Bane?

description: Trusted Space Autonomy is challenging in that space systems are complex artifacts deployed in a high stakes environment with complicated operational settings. Thus far these challenges have been met using the full arsenal of tools: formal methods, informal methods, testing, runtime techniques, and operations processes. Using examples from previous deployments of autonomy to the Remote Agent on DS-1, Autonomous Sciencecraft on EO-1, WATCH on MER, IPEX, AEGIS on MER, MSL, and M2020, and the M2020 Onboard planner, we discuss how each of these approaches have been used to enable successful deployment of autonomy. We next focus on relatively limited use of formal methods (both prior to deployment and runtime methods). From the needs perspective, formal methods represent the best chance for reliable autonomy as testing, informal methods, and operations accommodations do not scale well with increasing complexity of the autonomous system. However from the practice perspective, formal methods have been limited in their application due to difficulty in eliciting formal specifications and challenges in representing complex constraints such as metric time and resources. We discuss some of these challenges as well as the opportunity to extend formal and informal methods into runtime validation systems.

title: Understanding the Rupture Kinematics and Slip Model of the 2021 Mw 7.4 Maduo Earthquake: a Bilateral Event on Bifurcating Faults

description: We utilize the slowness-enhanced back projection (SEBP) and joint finite fault inversion (FFI), which combines body waves, surface waves, and 3D ground displacements to image the rupture process and slip distribution of the Mw7.4 Maduo earthquake. The results indicate a 160-km-long bilateral rupture occurring on a north-dipping fault. The WNW branch ruptures a length of ~75 km by 2.7 km/s, while the ESE branch ruptures a length of ~85 km by 3 km/s. Most slip concentrates above 10 km depth, with several major slip patches up to 5.7 m located on the east segment of the main fault and on the bifurcated branching fault. The comparison between SEBP and FFI shows the consistency between large slip pulses and high-frequency sources. We observe up to 3 m slip with large uncertainty deep beyond 15 km, which is abnormal since it requires rupture penetrating into the ductile layers. We propose that the deep slip could be an artificial compensation to match the observed moment, which indicates that the crust in the source region is more rigid than the current understanding. Or the deep creeping fault is turned into seismic ones by the strain localization and dynamic weakening. The stress analysis on the forks of the fault demonstrates that the branching behaviors on the eastern forks could be well explained by the pre-stress inclinations, rupture speeds, and branching angles.

title: Improving Small Satellite Communications in Deep Space A Review of the Existing Systems and Technologies with Recommendations for Improvement, Part I

description: Robotic exploration of the solar system using small satellites (SmallSats) is gaining popularity because of SmallSats’ lower cost and faster development cycle compared to primary science missions. A potential obstacle for deployment of SmallSats in deep space is the limitation associated with the communications link imposed by SmallSats' frugal power and antenna size. These technical limitations constrain the range and throughput of SmallSats and may impact their navigation performance. To allow SmallSats to play a greater role in deep space science endeavors, an enhanced communications architecture is proposed that will lessen the communications disparity between larger, more expensive missions and SmallSats. The objectives of the study are to define a communications architecture, in-flight and flight-to-ground, that is needed for planetary SmallSats, both standalone or in support of a larger mission; and to develop a guideline for primary spacecraft that would communicate with ride-along SmallSats. This work treats the space segment and the ground network as a whole to provide for improvements not only via investments in technology, but also via improvements in operational procedures. The study includes reviews of current communication concepts, technologies, and procedures; assessment of navigation needs; evaluation of the communication architecture performance for a range of destinations, and applications; and identification of any gaps in capability. The study product is a set of recommendations to space agencies and the planetary SmallSat community. The main thrust of these recommendations is investment in technology, such as radios, antennas, protocols, and methodologies. The concepts for improving communications capability of deep space SmallSats are discussed in a series of three papers, Improving Small Satellite Communications in Deep Space. This part (Part I) discusses SmallSat direct-to-Earth links as well as SmallSat communications equipment. Part II discusses navigation topics, proximity links, and networks and the use of the communications channel for science observations. The ground network is presented in Part III. Definitions and assumptions are provided in Part I.
