title: Stratospheric Balloon Missions for High Resolution Submillimeter-FIR Astronomical Spectroscopy

description: Many spectral lines that are key tracers of star formation lie in the submillimeter and far-infrared. This wavelength range is almost completely blocked for astronomical observations by terrestrial water vapor, and studies must be carried out from stratospheric or space platforms. The termination of the NASA/DLR airborne observatory SOFIA and the lack of any space mission for at least the remainder of the decade leaves stratospheric balloons as the only platforms for carrying out observations throughout the 1000 – 5000 GHz frequency range. I will present the science goals and technology overview of two NASA Antarctic balloon missions that are being constructed to observe some of the most important fine structure lines of abundant elements. The Galactic/Extragalactic Ultra/Long Stratospheric Terahertz Observatory (GUSTO; C. Walker, [University of Arizona], PI) will observe lines of N+, C+, and O0. Employing a 90cm diameter telescope, GUSTO will map the central portion of the Milky Way and the Large Magellanic Cloud. The Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter wavelengths (ASTHROS; J. Pineda, [JPL], PI), will observe both fine structure lines of ionized nitrogen. With a 2.5m diameter telescope, ASTHROS will have high angular resolution and be able to make detailed measurements of the electron density in ionized regions. Both GUSTO and ASTHROS employ heterodyne front ends using Hot Electron Bolometer (HEB) mixers and frequency-multiplied local oscillator sources to achieve high spectral resolution (R &gt; 106). Both missions employ digital ASIC spectrometer systems to carry out the spectral analysis over a ~4 GHz-wide band. GUSTO is expected to be launched in December 2023, and ASTHROS a year or two later, ushering in a new era of studies of the role of feedback in controlling the rate of star formation.

title: Smart Ice Cloud Sensing (SMICES) Sub-millimeterwave Combined Radar/Radiometer Instrument

description: Global observations of upper tropospheric water vapor and cloud ice particle size distribution and total ice water content are critically needed to improve weather and climate models [1]-[3]. Active/passive combined remote sensing of atmosphere from on-board radar and radiometer instruments is essential for obtaining high quality data products for advancing science. In addition, autonomous instrumentations embarked in space borne platforms can help in achieving improved accuracy, stability and spatio-temporal resolution of these measurements. The Smart Ice Cloud Sensing (SMICES) instrument is designed to provide high accuracy, enhanced resolution global measurements of cloud ice and tropospheric water vapor by utilizing synergic operation of radar and radiometer instrument through an on-board artificial intelligence (AI) processor. SMICES is collaborative effort between Northrop Grumman Aerospace Systems (NGAS) and NASA/Caltech Jet Propulsion Laboratory (JPL) supported by NASA ESTO under IIP-19. The SMICES receivers are based on 25-nm InP High Electron Mobility Transistor (HEMT)-based low-noise amplifiers (LNAs) designed collaboratively by NGAS and JPL and they are packaged in integrated receiver front-ends to provide low-noise and low-power operation in a small form factor at millimeter- and sub-millimeter-wave frequencies [4]. These include direct-detection receivers at 250 GHz, 310 GHz and 670 GHz, and heterodyne water-vapor sounding channels at 380 GHz. SMICES instrument has a 50 W Traveling Tube amplifier (TWTa) 239 GHz radar instrument autonomously controlled by the on-board real-time AI processor. SMICES receivers are designed to perform end-to-end calibration at each scan by viewing both an ambient calibration target near 290 Kelvin and the cosmic background noise of 2.73 Kelvin. The novel pseudo-correlation calibration is performed at 250 and 310 GHz radiometric channels using a 90° hybrid design. This novel calibration technique integrated with phase switches can provide high resolution measurements by allowing simultaneous acquisition of antenna and reference samples. Furthermore, the novel 1/f noise mitigation technique applied to all SMICES receiver channels for substantially reducing 1/f noise from acquired data samples [5]. SMICES instrument is being designed to fit into a SmallSat instrument but the technology demonstration will be performed from a Gulfstream II aircraft. The CAD model showing the airborne compatible design of the SMICES instrument is shown in Fig. 1 where the instrument is built for operating from the nose-cone of the aircraft.

title: Outcome Prediction Framework for Mission Operations of Autonomous Spacecraft

description: As planning and autonomy in general become increasingly deployed on board spacecraft, missions will face a paradigm shift in how ground operations teams command and interact with the spacecraft: moving from specifying timed sequences of commands to high-level goals that on-board autonomy will elaborate based on the spacecraft’s state and sensed environment. It will become increasingly difficult for operators to predict a mission's outcome as autonomous spacecraft venture into deeper space, react to unknown conditions, and face stronger communication constraints. However, data from simulated autonomous missions can be analyzed and leveraged in order to allow operators to make informed decisions when selecting mission parameters and high-level goals. To this end, our paper presents a framework that gains insights from simulation data in order to help operators of autonomous spacecraft missions to predict, explain, and search for specific outcomes given a set of high-level goals. We show and discuss how our approach can help operators to better understand predictions, explore options and make informed decisions. To this end, we describe a case study that builds upon previous work on simulated autonomous spacecraft missions to the Neptune-Triton system where the spacecraft uses an automated planning and execution framework to make onboard decisions.

title: “In OBP We Trust”: Verification and Validation of the M2020 On Board Planner Flight Software

description: With a planned deployment to the Perseverance roverin October 2023, the Mars 2020 On Board Planner (OBP) flightsoftware (FSW) will allow the rover to conserve energy and au-tonomously perform more activities when surplus resources (i.e.energy, data volume, time) are available. This functionality iscritical to support efficient resource management and maximizethe productivity of the vehicle as the rover’s battery degradesover time, particularly as the Mars Sample Return mission(MSR) may rely on Perseverance to facilitate sample deliveryto the return lander. Up until OBP’s deployment, operatorshave used the Master/Sub-Master paradigm (M/SM) for allMars missions to-date, in which rigid plans are uplinked to therover based on highly conservative models of activity resourceconsumption and duration that can unnecessarily constrain on-board plans. Thus, OBP must be robust enough to merit thetrust of mission science and operations personnel and preservethe health and safety of the spacecraft. To this end, we havecompleted a thorough verification and validation (V&V) cam-paign of the first iteration of OBP that will be deployed to therover as part of new Simple Planner (SP) operations paradigm.The campaign heavily relied on software testing to ensure thatcore flight software capabilities were met and that the softwarecomprehensively covered potential edge cases. In this paper,we motivate the need for a thorough V&V campaign going intothe deployment of On Board Planner to the Perseverance rover,contextualize how OBP integrates with the rest of the vehicle’sflight software, and leverage three case studies to evidence howtesting provided critical support towards the successful infusionof onboard scheduling software on the rover.

title: The Next Generation Radioisotope Thermoelectric Generator Project - Overview and Progress Status

description: The Next Generation Radioisotope Thermoelectric Generator (Next Gen RTG) Project is a spaceflight system project within NASA’s Radioisotope Power Systems (RPS) Program. The project, in partnership with the Idaho National Laboratory (INL) / Battelle Energy Alliance (BEA), will build and deliver an unfueled, flight qualified Radioisotope Thermoelectric Generator (RTG) system based on RPS Program needs. The Next Gen RTG Project aims to assure the availability of high-power, vacuum-rated RTGs to enable future deep space missions. The Project team is developing that capability through a multi-phase effort that leverages the heritage General Purpose Heat Source - RTG (GPHS-RTG) design and available legacy hardware. The Project’s primary aim is to re-establish the capability to manufacture a silicon germanium (SiGe) unicouple based thermoelectric converter and associated hardware with minimal changes to the heritage GPHS-RTG design. The project will also refurbish the GPHS-RTG Flight Unit #5 (F-5) located at INL and verify its compliance with heritage GPHS-RTG requirements. This paper will detail the project’s plans for the development of these systems. Management approaches, technical challenges, and risks will also be discussed.

title: TID Testing of SiGe Microelectronics Using High-Flux 1-MeV Electrons for Europa-Surface Missions

description: Europa lies in Jupiter’s colossal radiation belt, producing radiation surface conditions that are so severe (5 Mrad[Si]) that most modern electronics would experience degradation in a matter of days. This challenge, coupled with the sub-100 K surface temperatures, leads to a very hostile environment for a viable electronic infrastructure. To help enable a future mission for landing on Europa’s surface, there must be efficient terrestrial testing facilities in place to model the effects of the environment on the requisite microelectronics. The Jet Propulsion Laboratory’s Dynamitron facility, an electrostatic particle accelerator, provides unique TID testing capabilities with high flux, high energy electrons at both room (300 K) and at cryogenic (100 K) temperatures. We have found that radiation test methods for microelectronics require additional considerations in the high flux, high energy, cryogenic environment within the chamber. This paper outlines the best practices required for success, and demonstrates the efficacy of these methods using silicongermanium (SiGe) microelectronic devices and circuits, a leading candidate technology for Europa surface missions.

title: Why Workmanship Vibration Tests is Important to Prepare Flight Hardwar for launch

description: Recently, there has been a tendency during random vibration and sine vibration testing for spacecraft projects to eliminate or reduce minimum workmanship to levels low enough that the objective of performing an adequate workmanship screen during the test is defeated. The chief reason for not exposing flight hardware to adequate workmanship levels is that pre-test analysis shows the test will exceed the predicted structural capability of the hardware. Upon reviewing some of the recently predicted results, it became clear that some analysts did not include the force-limited method as part of their base-shake analysis. In this paper we will briefly discuss the history of the application of the minimum workmanship requirement at JPL and provide technical reasons why the minimum workmanship level has become a standard part of the screening tests that are performed on flight hardware. We will show that if force-limited analysis is performed properly, it will most likely bring structural margins into positive territory, therefore, eliminating the need for lowering workmanship requirements. We will provide a couple of examples exploring the importance of proper structural analysis in relationship to verifying that fight hardware is ready for launch.

title: Tropical Deep Convection, cloud feedbacks and climate sensitivity

description: This paper is concerned with how the diabatically-forced overturning circulations of the atmosphere, established by the deep convection within the tropical trough zone (TTZ), first introduced by Riehl and Simpson (1979), fundamentally shape the distributions of tropical and sub-tropical cloudiness and the changes to cloudiness as Earth warms. The study first draws on analysis of a range of observations to understand the connections between the energetics of the TTZ, convection and clouds. These observations reveal a tight coupling of the two main components of the diabatic heating, the cloud component of radiative heating, shaped mostly by high clouds formed by deep convection, and the latent heating associated with the precipitation. Interannual variability of the TTZ reveal a marked variation that connects the depth of the tropical troposphere, the depth of convection, the thickness of high clouds and the TOA radiative imbalance. The study the examines connections between this convective zone and cloud changes further afield in the context of CMIP6 model experiments of climate warming. The warming realized in the CMIP6 SSP5-8.5 scenario multi-model experiments, for example, produces an enhanced Hadley circulation with increased heating in the zone of tropical deep convection and increased radiative colling and subsidence in the sub-tropical regions that then impacts low cloud changes and in turn the model warming response through low cloud feedbacks. The pattern of warming produced by models, also influenced by convection in the tropical region, also has a profound influence on the projected global warming.
