title: SUPER-EARTH LHS3844b IS TIDALLY LOCKED

description: Short period exoplanets on circular orbits are thought to be tidally locked into synchronous rotation. If tidally locked, these planets must possess permanent day- and nightsides, with extreme irradiation on the dayside and none on the nightside. However, so far the tidal locking hypothesis for exoplanets is supported by little to no empirical evidence. Previous work showed that the super-Earth LHS 3844b likely has no atmosphere, which makes it ideal for constraining the planet’s rotation. Here we revisit the Spitzer phase curve of LHS 3844b with a thermal model of an atmosphere-less planet and analyze the impact of non-synchronous rotation, eccentricity, tidal dissipation, and surface composition. Based on the lack of observed strong tidal heating we rule out rapid non-synchronous rotation (including a Mercury-like 3:2 spin-orbit resonance) and constrain the planet’s eccentricity to less than ∼ 0.001 (more circular than Io’s orbit). In addition, LHS 3844b’s phase curve implies that the planet either still experiences weak tidal heating via a small-but-nonzero eccentricity (requiring an undetected orbital companion), or that its surface has been darkened by space weathering; of these two scenarios we consider space weathering more likely. Our results thus support the hypothesis that short period rocky exoplanets are tidally locked, and further show that space weathering can significantly modify the surfaces of atmosphere-less exoplanets.

title: Pre-Launch Lessons Learned from NASA’S Deep Space Network Support for the Artemis I Mission to the Moon

description: NASA’s Deep Space Network (DSN) serves as a critical element in the exploration of deep space, providing telecommunication services such as tracking, telemetry, command, and delivery of science data to its customers around the globe. In addition to supporting robotic spacecraft for scientific missions, the DSN also supports human spaceflight (HSF) endeavors, including NASA’s flagship Artemis missions to the Moon. This paper describes DSN lessons learned during preparations for the first Artemis mission, Artemis I. Topics covered include DSN performance and reliability, network loading, interface management, international collaboration and the role of international partners. Lessons learned will be applied to future missions, including Artemis II and beyond.

title: Development and Qualification of a 12-kW Hall Thruster for Deep-Space Missions

description: NASA and Aerojet Rocketdyne are developing and qualifying a 12-kW Hall thruster for deep-space mission applications through the Advanced Electric Propulsion System (AEPS) project. The core technology of the thruster derives from the NASA-developed Hall Effect Rocket with Magnetic Shielding (HERMeS), which had a design lifetime of 50 kh at specific impulses up to 3000 s. AEPS is planned to be first used on Maxar’s Power and Propulsion Element (PPE) spacecraft as part of NASA’s Lunar Gateway under the Artemis project. The AEPS project consisted of a development phase, which concluded with Critical Design Review in March 2022, and is now entering qualification and flight hardware fabrication. The development phase included thruster and component testing that demonstrated the performance of the hardware for the required dynamic and thermal environments and that erosion rates were consistent with meeting the thruster life requirement. Qualification hardware includes two thrusters, a hollow cathode, and several other thruster components that will undergo qualification testing. Thruster qualification will span performance, dynamic, thermal, and wear testing. The hollow cathode and other components will be subjected to thermal cycling tests. Physics-based plasma modeling validated with detailed plasma measurements is being used to establish the required margins for thruster life. Flight hardware fabrication of three thrusters is running in parallel to the qualification campaign.

title: Hyperspectral Data Compression and Cloud Screening using a High-Performance Embedded System-on-a-Chip for the Earth Surface Mineral Dust Source (EMIT) Instrument on the International Space Station (ISS)

description: System-on-a-chip (SoC) devices promise lighter, smaller, cheaper, more capable and more reliable space electronic systems. This paper describes the focal plane interface electronics – digital (FPIE-D) Xilinx Zynq-based data acquisition, cloud-screening, compression, storage and downlink computing system developed by the Jet Propulsion Laboratory (JPL), Alpha Data, Correct Designs and Mercury Systems for the NASA Earth Surface Mineral Dust Source (EMIT) instrument. EMIT is an imaging spectrometer that acquires 1280 cross-track by 328 band images at 216 images/sec. Following launch (14 July 2022), EMIT has been installed outside the International Space Station (ISS) and is collecting data from science targets in arid dust source regions of the Earth. EMIT will be used to study the mineral dust cycle which has multiple impacts on the Earth System. The science objective of EMIT is to close the gap in our understanding of mineral dust heating and cooling impact on the Earth now and in the future by determining the surface mineralogy of mineral dust sources.

title: RADIOMETRIC VALIDATION OF MOREHEAD STATE UNIVERSITY GROUND STATION

description: The 21-m antenna ground station at the Morehead State University has undergone an upgrade over the past several years to make it ready to support upcoming lunar (and beyond) missions. Among the first missions to be supported are the Artemis 1 Cubesats including Lunar IceCube, Lunar H-map, NEAScout, and CuSP, as well as the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) mission. The ground station is now furnished with new X-band transmission and reception capabilities , with the same signal processing for telemetry, tracking and command functions as those in the NASA Deep Space Network (DSN). Architecturally, the Morehead station appears just like any other DSN antenna, albeit with a different aperture size, transmitting power and receiving noise temperature. The Morehead station is considered as a DSN affiliated station. It can be scheduled to support DSN missions via a common DSN scheduling interface. As part of the effort to certify the system readiness to support Artemis 1 Cubesat mission operations, we tried to demonstrate the system performance with spacecraft that are currently in flight, to the extent possible. Validation of telemetry processing was relatively easy to accomplish by shadow tracking spacecraft scheduled for DSN tracking. These shadow passes were conducted on a non-interference basis to avoid impact to the missions. Performance metrics such as received carrier signal to noise ratio (SNR) was used to characterize the system G/T (Gain over Noise Temperature) of the Morehead antenna. Due to the difference in performance, e.g., smaller aperture and higher noise temperature, a limited number of passes have sufficient link margin for successful telemetry symbol synchronization and decoding at the Morehead station. In those cases, the received symbol SNR was also used for performance characterization, as a supplement to the carrier SNR.
