title: Dynamic Conductivity Processes in Glass-Filled Polyimide Circuit Boards

description: Assessments of the risk of electrostatic discharge(ESD) due to spacecraft charging require knowledge of materials’conductivity in flight-like conditions. Due to the difficulty inmeasuring and modeling conductivity in space conditions, it iscommon to conservatively assume the minimum steady-state darkconductivity. This study investigates impacts of charging rate,temperature, electric field, and time on the dynamic conductivityof glass-filled polyimide circuit board materials. The chargestoragemethod of measuring conductivity was used on samplesmounted on a cold plate in vacuum. Charging was performedincrementally with conductivity measured between electronexposures. Beam ramp down conditions were varied to investigatethe impact of charging rate on the observed charge decay.Observed conductivity does not appear to depend on the rate ofbeam shut off. Conductivity does depend strongly on electric field,time, and temperature. These effects typically are studiedseparately.

title: Optical and opto-mechanical design of the PRIMA telescope

description: The PRIMA (Probe Far-Infrared Mission for Astrophysics) system will be a 1.8 meter, multi-mode, cryogenic, far-infrared space-based observatory consisting of a collecting afocal telescope followed by multiple spectrometer and imager instruments. The afocal telescope collects light from targets across a total field of view that is selectable by means of two different internal scan mirrors, one each for the spectrometers and the imagers. The primary and secondary mirrors are common to both instrument groups, and working with an angular field offset between instruments. The optics after the secondary and up to the scan mirrors are separate. The telescope provides two separate collimated and demagnified beams emerging from the scan mirrors to the spectrometer and imager instrument groups. Design-driving factors include the need to demagnify the entrance beam to fit a heritage scan mirror, and the need for an accessible field stop located clear of any mirror. This paper describes the requirements, configuration trade and development, preliminary optical design, and performance analysis of the telescope.

title: ADDRESSING THE HIGH-RATE DEEP SPACE COMMUNICATIONS SHORTFALL IN NASA’S SPACE TECHNOLOGY MISSION DIRECTORATE’S ENVISIONED FUTURE

description: NASA’s Space Technology Mission Directorate (STMD) has identified key technologies needed for future crewed and robotic exploration and science missions. STMD is helping to build the civilian technology base by working with other NASA Mission Directorates, other United States government agencies, commercial industry, and academia to identify technology shortfalls and to develop plans to address them. One critical area of shortfalls lies with deep space communications and navigation. While NASA had huge success to date with the Deep Space Network (DSN), recent studies have shown that without enhancements to current systems, the DSN will be unable to support the anticipated increases in the pace of space exploration or the expected higher data rates from deep space needed soon without severely impacting other missions [1]. High-rate communications from the Moon and beyond is needed to enable future exploration and science missions currently being developed or under consideration. For example, a robust communications infrastructure will be needed to support a sustained human presence on the Moon and its eventual industrialization. High data rate trunk lines between the Earth and the Moon are needed to reduce the number of individual links. The human exploration of Mars will also require high-rate communications between Earth and Mars. Return data rates to Earth from Mars for a single link, for example, are anticipated to be greater than 100 Mb/s; forward data rates to Mars, based on experience from the International Space Station, are anticipated to be greater than 20 Mb/s. Future deep space science missions will also require higher data rates than possible with today’s technology and the current capabilities of the DSN. To support future exploration and science needs, it will be necessary to upgrade the DSN to enhance its radio frequency (RF) capabilities. In addition, it is envisioned that NASA will gradually introduce optical communications to augment its RF systems [2]. Optical communications will enable new science and exploration missions by providing high data rates and better navigation over long distances [3]. This paper will briefly describe STMD’s envisioned future for deep space communications in the 2030+ timeframe and the technology roadmaps being developed for both radio frequency and optical systems.

title: Additive Manufacturing of a Deployable Monolithic Camera Cover for Planetary Exploration

description: Camera covers are mechanisms commonly used to protect optical instruments during the launch and landing of a spacecraft. The mechanisms have two basic functions: protect optics from foreign objects and debris while stowed and move out of the camera’s field of view when deployed. Mechanisms of this sort are easily over engineered, with the final assembly consisting of dozens of piece-parts. This project presents a design that takes advantage of additive manufacturing to combine components, including flexures that deploy the cover. The proposed design would decrease part count and cost while maintaining the function and reliability of traditional camera cover mechanisms. As part of the development of the design, the performance of printed nylon and Ti-6Al-4V springs were tested and compared to analytical values.

title: Machine Learning Application for Lambert's Problem

description: This study presents a neural network Lambert's approximator, a novel approach to address Lambert's problem using deep learning. The main contribution lies in providing a means to approximate transfer trajectories for preliminary mission design, utilizing machine learning in conjunction with prior knowledge in astrodynamics. By normalizing the gravitational parameter of a central body and initial distance, this approach is applicable to any two-body system, encompassing not only interplanetary trajectories but also moon tour problems. The proposed neural network model, trained on a dataset of transfer trajectories, demonstrates efficiency in approximating these trajectories. The study delves into the neural network architecture, training methodology, and performance evaluation, highlighting the potential of this approach to enhance the efficiency of preliminary mission design processes. The performance evaluation of the presented approximation approach is conducted with a Porkchop plot validation, speed test, and mission design applications such as the Cassini trajectory and Europa Clipper trajectory.

title: Performance Analysis and Data Processing for the Mars Sample Recovery Helicopter in the Jet Propulsion Laboratory 25-ft Space Simulator

description: Ingenuity became the first helicopter to fly on Mars and completed 72 flights. Success of Ingenuity resulted in various research efforts to further explore Mars via vertical flight, including the possible use of two optimized Ingenuity-sized helicopters to retrieve samples for the 2028 Mars Sample Return Mission (MSR). To aid in the design process for the two Sample Retrieval Helicopters (SRH), heritage and optimized Ingenuity rotors were tested at the NASA Jet Propul- sion Laboratory in the 25-foot Space Simulator. Three test campaigns were performed using the Ingenuity rotors and optimized SRH rotors for several rotor speeds, densities, configurations, and collectives to identify performance limi- tations. These three test campaigns included the Engineering Design Model 1 (EDM-1) with and without a cruciform box, Transonic Rotor Test (TRT) rig, and Dual Rotor Test (DRT). Experimental setup, test matrix, data processing, data quality, and the performance results for EDM-1, TRT, and DRT campaigns are presented and discussed. Exper- imental results from the test campaigns will aid in future experimental methods and validation efforts for planetary rotorcraft exploration.

title: Analysis of GNSS Receiver Tracking during High-Latitude Ionospheric Scintillation

description: Data collected from Wide Area Augmentation System (WAAS) reference stations (WRS) in Alaska is analyzed to investigate GNSS loss of lock (LOL) events. While L-band amplitude or intensity scintillation rarely occurs in the auroral zone because of the spectral filtering effect (Pi et al., 2017), strong carrier phase scintillation can cause a receiver to lose lock. To understand and predict LOL events under scintillation conditions, it is desired to identify and measure the phase scintillation effect using GNSS data recorded by the reference receiver. For this purpose, measurements of the rate of TEC index (ROTI) are obtained using 1 Hz data from the WRS for 1-minute intervals, which characterize dual-frequency phase fluctuations caused by small-scale ionospheric irregularities. Such 1-minute ROTI measurements, or ROTI1m (hereafter), based on 1 Hz data are different from those made using 30-sec sampled data (Pi et al., 1997), the latter filtering out certain fluctuations in shorter periods. The receiver LOL events in and near the auroral zone are analyzed with ROTI1m data. Our dataset consists of four days of L1 and L2 carrier phase data from three WAAS reference stations, each station with three separate receiver antennas. All four days are during periods of geomagnetic storms and high ionospheric activity. We find evidence suggestive of a relation between ionospheric-induced phase perturbations and LOL at these high latitudes. In addition, we also look at amplitude scintillation events through the lens of S4c (Luo et al., 2020), and investigate their relation to the LOL events. We find very few instances of amplitude scintillation. It is also found that, interestingly, amplitude scintillation shows poor correlation between antennas separated by about 4 meters at the same site. As a result, we find no relation between amplitude scintillation and loss of lock in the data from these stations in and near the auroral zone.
