title: All Solid-State Transmitter (ASTRAM) for Next-Generation Ground-Based Planetary Radar

description: This paper presents the development of a newtype of transmitter for next-generation ground-basedplanetary radar. The transmitter is based on mature,reliable solid-state technology, and provides analternative to traditional amplifier tube-basedtransmitter systems. The technology described is ascalable transmitter system that utilizes a low-lossmethod of power combining the RF outputs of multipleGallium Nitride (GaN)-based Monolithic MicrowaveIntegrated Circuits (MMICs) in parallel to achieve acoherent amplified output signal. The power combiningtakes place within modular devices that we refer to asspatial power combining amplifiers (SPCAs). The SPCAdiscussed in this paper combines an arrangement ofsixteen 85 W MMIC amplifiers to produce ~1.3 kWcontinuous-wave power at a center frequency of8.56 GHz. The modular nature of the SPCA units allowsthem to be further combined hierarchically viawaveguide-combining techniques to form scalable highpowertransmitter systems. This paper presents the basicarchitecture and full laboratory characterization of an Xbandsolid-state SPCA unit, including key deviceperformance results, reliability analysis, andenvironmental sensitivities.

title: DART MISSION DESIGN AND NAVIGATION LESSONS LEARNED FOR FUTURE PLANETARY DEFENSE MISSIONS

description: This paper summarizes the lessons learned by the Double Asteroid Redirection Test (DART) Mission Design and Navigation (MDNAV) team most relevant to future planetary defense missions and studies. From the perspective of its trajectory and navigation, DART is a reasonable analog for an operational planetary defense (PD) response mission: either a rapid reconnaissance flyby or a kinetic impactor mission. We have identified 9 lessons that we hope will benefit future PD response mission teams. Broadly speaking, they are ordered from mission design focused to navigation focused.

title: Two-way Ranging using OFDM Waveform with Application to Lunar Surface Navigation

description: We present a ranging system which measures the distance between two radio nodes by estimating the time of flight (ToF) of a series of short radio frequencybursts modulated using an orthogonal frequency division multiplexing (OFDM) waveform. ToF is estimated by periodically exchanging two precisely timed OFDMframes and measuring the time of reception (ToR) using a cross-correlation-based technique. The two nodes then exchange the estimated ToRs in subsequent OFDMframes and independently compute an estimate of the ToF.OFDM-based waveforms have exploded in popularity for telecommunications applications on Earth due to their resistance to multipath effects and their fastimplementation using the FFT algorithm. They are deployed globally as part of wireless LANs using the IEEE 802.11 series of standards and as part of mobilenetworks using the 4G LTE and 5G NR series of standards. The inherent resistance to multipath effects makes OFDM a promising candidate for operations on therough lunar surface when compared to the single carrier waveforms traditionally employed in deep space.The main application envisioned for this system is a ground-based local positioning and navigation system serving exploration, science, and commercialactivities within a fixed region on the lunar surface. Multiple concepts providing positioning and navigation services on the lunar surface have been proposed,with a lunar global navigation satellite system (LGNSS) being the preferred option. However, in case a full-scale LGNSS constellation is unavailable due toe.g., delays, budgetary issues, or physical constraints, a ground-based local navigation system utilizing a fixed set of transmitting stations could become aviable alternative. In this case, the low-complexity two-way ranging scheme presented in this work can provide the necessary range estimates required forobtaining the positions of astronauts, rovers, and/or other equipment in a region of interest on the lunar surface.In addition to ranging, our system is flexible enough to be easily upgraded to include a low-rate communications signal, thus potentially forming a completejoint positioning and messaging solution for the lunar surface. An initial version of our proposed ranging system was implemented and demonstrated as a softwareapplication utilizing devices from National Instruments’ Universal Software Radio Peripheral (USRP) line of software-defined radios, which provides astraightforward path towards porting to space-grade hardware in the future. We provide a detailed exposition of the transceiver architecture as well as resultsof indoor lab experiments and outdoor test campaigns.

title: Designing the Ka-Band System Architecture for Science Data Return on the SPHEREx Mission

description: The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission, a part of the NASA Astrophysics Medium Explorer (MIDEX) program, will produce the first all-sky near infrared spectral survey of the universe, collecting images every 6” in spectral bands between 0.75 and 5.0 μm. Over the course of its 27-month mission, the SPHEREx Observatory will image the entire sky four times from a 650 km sun-synchronous polar orbit, producing up to 175 Gbits per day of science data which will be returned via the NASA Near Space Network Direct-To-Earth (NSN-DTE) Ka-band service at a rate of 600 Mbits per second. As a survey mission, SPHEREx relies on high system availability and reliable data return to meet its science goals. The constraints of the instrument, however, create key challenges in designing a downlink system design that is capable of returning the mission data set while maintaining the performance of the project’s one instrument. SPHEREx’s passively-cooled infrared instrument is sensitive to thermal disruptions from the environment and the shields that protect it from environmental heating provide only a limited available pointing zone, which in turn constrains the available maneuverability of the vehicle to track an NSN-DTE station. This piece of the SPHEREx design presents an excellent case study in systems engineering. To achieve a cost-effective design that meets both mission constraints and mission needs, SPHEREx needed to balance designs across the instrument, spacecraft telecom subsystem, spacecraft attitude control operations, and ground system, touching multiple key project budgets and resulting in major architectural decisions in both the flight telecom architecture and the planning systems on the ground. In this paper, we will discuss the end-to-end architecture of the SPHEREx science data downlink path and describe the unique challenges and design trades the project executed to develop it. The discussion will include the constraints of the mission and vehicle that drive the downlink design, the resulting spacecraft Ka-band architecture, the development of an optimizer ground tool to plan downlinks, and pointing analysis tools that integrate downlinks with the science plan.

title: Cold Environment Test Campaign of Face Seal Candidates for the Mars Sample Return’s Secondary Containment Vessel

description: The paper breaks down the exploration of implementing face seals for locking interfaces in space applications. These efforts were undertaken at NASA’s Jet Propulsion Laboratory for the planned Mars Sample Return Campaign. The hardware in which the face seals were contained would spend years orbiting Mars and would eventually return to Earth along with the Mars samples. Due to the extended duration of the hardware being in Martian orbit, the mission environment needed to be simulated to understand the capabilities of the face seal. To achieve this objective, two testing campaigns were devised to characterize the leak rate and the compression force of various face seal types. The testing campaign will identify the effects of cold environments on seal performance. The test data will inform design decisions to ensure a robust seal was made and maintained under flight conditions.

title: 3/8th Scale Testing for the MSR Sample Retrieval Lander Touchdown Event

description: The Mars Sample Retrieval Lander would be the largest lander (over 2300kg) to land on Mars. To mimic the system-level structural dynamics of touchdown in Mars gravity on Earth, a drop test campaign is completed using a dynamically similar 3/8th scale prototype. The testbed capabilities include uneven terrain, induced horizontal velocity, induced pitch rate, and low/high-friction surface conditions.This prototype lander has 4 inverted tripod legs and a full instrumentation suite. A flexible-body MSC ADAMS model with nonlinear crushable core and cantilever load limiter representations is correlated to the physical tests such that displacements, velocities, accelerations, member forces, and bending moments agree with observations.The process of early scaled testing and model correlation helps develop a greater understanding of system level dynamics and sensitivities that drive landing leg design and helps provide a test-validated ADAMS model used in touchdown Monte Carlo simulations to ensure a successful landing on Mars.

title: Ground-Assisted Position Navigation and Timing (PNT) for Moon and Mars

description: The recent exploration initiatives for robotic and human missions to the Moon and Mars requires long-term communications and navigation infrastructures that provide accurate and autonomous PNT services for orbiting and surface users. NASA launched the Communication Relay and Navigation System (LCRNS) project in 2022 to meet the needs of the Artemis missions and other lunar missions. ESA, JAXA, other space agencies, and commercial entities may contribute additional lunar relay orbiters that are compatible with the NASA’s orbiters via the LunaNet Interoperability Specifications [1]. To ensure sustained human presence at the Moon, NASA plans to deploy surface infrastructure elements that can survive the lunar nights. We are investigating the operation concept and PNT performance by augmenting the lunar relay network with a surface station with the following capabilities: 1. Provide short-range time distribution to orbiting and surface spacecraft. 2. Transmit a GNSS signal to augment the orbital determination (OD) schemes of lunar spacecraft for fast OD convergence. The transmitter can also act as a surface beacon that guides the lunar spacecraft during dynamic events like decent and ascent. 3. Receive and Earth’s GNSS signals and estimate corrections for orbiting spacecraft. This enables improved OD performance and accurate relative navigation of users on lunar surface. The Joint Doppler Ranging (JDR) method requires as little as one orbiter to perform real-time position fix of a surface user. This is particularly useful during the early stage of lunar relay network deployment when the number of orbiters are small. The lunar surface station architecture is directly applicable to the Mars relay network, and this supports the NASA Moon-to-Mars initiative.

title: The K-Band (24 GHz) Celestial Reference Frame Determined from Very Long Baseline Interferometry Sessions Conducted Over the Past 20 Years

description: The third realization of the International Celestial Reference Frame (ICRF3) was adopted in August 2018 and includes positions of extragalactic objects at three frequencies: 8.4 GHz, 24 GHz, and 32 GHz. In this paper, we present an update of the celestial reference frame estimated from Very Long Baseline Interferometry measurements at K-band (24 GHz) including data until June 2022. The observations of the radio sources are conducted with the Very Long Baseline Array from the U.S. territory and in the southern hemisphere with single baseline observations between the HartRAO 26m antenna in South Africa and the Hobart 26m in Australia. The data set starts in May 2002 and currently consists of more than 120 24h observing sessions performed over the past 20 years. Since the publication of ICRF3, the additional observations of the sources during the last four years allow maintenance of the celestial reference frame and more than 200 additional radio sources ensure an expansion of the frame. We determine the updated K-band solution (K-CRF) with two independent analysis software packages (VieVS and Calc/Solve) and describe the differences in the solution strategy. We compare the updated K-CRF to ICRF3-K using the so-called vector spherical harmonics to provide information about systematic differences between two astrometric catalogs.
