title: (ExEP) Coralign: a software package for coronagraphic alignment and calibration (paper)

description: Coronagraphy is one of the leading technologies for directly imaging exoplanets. To suppress starlight at high contrast, coronagraphic masks must be aligned with extreme accuracy and precision, and model-based wave- front correction algorithms must be given accurate calibration parameters. Manual alignment and calibration of coronagraphic masks is typical in most testbeds, but automation is necessary to guarantee accuracy and repeatability. To meet the strict requirements of NASA’s Nancy Grace Roman Space Telescope Coronagraph Instrument, the Jet Propulsion Laboratory created a unit-tested software package for coronagraphic alignment and calibration. For public release, we made the software more user friendly and added more routines from the High Contrast Imaging Testbed (HCIT) facility. This open-source software package, named Coralign, contains a suite of algorithms for the alignment and calibration of the unmasked beam, deformable mirrors, and several types of coronagraphic masks (e.g., an occulter, vortex, Lyot stop, apodizer, and field stop). Coralign is available in Python (and soon in MATLAB) at github.com/nasa-jpl/coralign.

title: Psyche Mission System Level Guidance, Navigation, and Control Off-Nominal Testing

description: “Psyche: Journey to a Metal World” is a discovery-class NASA mission to explore the largest known metal asteroid, (16) Psyche, to determine if it is the exposed core of a planetesimal. Led by principal investigator Dr. Lindy Elkins-Tanton of Arizona State University, Psyche is a collaboration between the Jet Propulsion Laboratory (JPL) and Maxar Technologies. It carries a suite of science instruments to accomplish its mission, including imagers, gamma ray and neutron spectrometers, and magnetometers. It also hosts a technology demonstration, the Deep Space Optical Communications (DSOC), and is the first mission to use Hall electric propulsion thrusters beyond lunar orbit. Psyche is scheduled to launch in October of 2023. This paper focuses on the off-nominal testing that was conducted on the Guidance, Navigation, and Control (GNC) software after its 2022 launch slip. To verify the system is robust enough to handle off-nominal scenarios, a wide array of GNC related single faults was injected into the system while running a real-time flight simulation on the testbed. The faults were injected during launch, safe mode, and nominal operations spanning a wide variety of mission phases, hardware configurations, and launch conditions, and were chosen to test the vulnerabilities of the system. The faults themselves touched all GNC devices, ranging from solar array deployment failures to biases in the inertial measurement units to leaky thrusters. This paper will also discuss the venues on which testing was conducted. While the GNC algorithms were developed in an environment isolated from the rest of the flight system, the off-nominal testing was conducted on the flight software testbeds at JPL, which leverage engineering models of the Psyche Compute Element (PCE) that run Psyche’s flight software in its entirety. The PCE interfaces with simulated software models of the GNC devices, plus an environmental model, ephemeris, and dynamics model. Finally, this paper will examine how the results of the off-nominal testing resulted in updates to the GNC algorithms, fault protection (FP) parameters, and operational constraints.

title: UNCERTAINTY QUANTIFICATION OF THE GAIN BUDGET FOR THE KA-BAND DEPLOYABLE MESH REFLECTOR ANTENNA FOR INCUS

description: INCUS (INvestigation of Convective UpdraftS) is an Earth Science project approved by NASA in 2022. The goal of the mission is to study in detail how water vapor and droplets move inside tropical storms and thunderstorms and understand their effects on weather and climate models. To carry out this study, the mission will use three almost identical SmallSats, each one equipped with a Ka-band radar heritage of Raincube. The deployable mesh reflector antenna is a new 1.6m design provided by Tendeg. The bus for each of the three observatories is provided by Blue Canyon Technology (BCT), while Colorado State University leads the science team of the project. This paper presents the general architecture of the three observatories with particular emphasis on the radar antenna subsystem design. In particular, a statistical analysis to evaluate the impact of fabrication tolerances of the deployable mesh reflector surface and their effect on the antenna gain will be presented.

title: The Decadal Survey Testbed 2: A technology development facility for future exo-Earth observatories

description: Due to the reporting from the Astro2020: Decadal Survey for Astronomy and Astrophysics, the direct imag- ing of Earth-like exoplanets has become a leading priority for research and development in astrophysics. In response to this survey, NASA has selected the Habitable Worlds Observatory (HWO) as its next astrophysics flagship mission. However, the current state-of-the-art coronagraph technology is not sufficient to achieve the required contrast (∼ 10−10) with HWO’s proposed configuration. Improving the technology readiness level of coronagraphs for HWO will require extensive research and development. To increase its capacity to support this objective and to provide the community with a new resource to perform versatile coronagraph technology devel- opment, NASA’s High Contrast Imaging Testbed (HCIT) facility at the Jet Propulsion Laboratory (JPL) has commissioned the Decadal Survey Testbed 2 (DST2), a state-of-the-art vacuum coronagraph testbed. It’s com- missioned architecture incorporates a 2K-actuator Boston Micromachines deformable mirror and a traditional Lyot coronagraph, and features a flexible design capable of accommodating different coronagraph technologies including tip/tilt mirrors, segmented apertures, reflective pupils, disturbance injection, wavefront sensing and control, and the integration of additional sources or telescope simulators with minimal reconfiguration. DST2 has repeatably achieved 1 × 10−9 monochromatic raw contrast, and 3.3 × 10−9 raw contrast in a 10% bandwidth centered at 550nm in a 180 degree dark hole from 3λ/D to 9λ/D. Additionally, DST2 uses new 20-bit DM electronics capable of a 650 femtometer DM actuator resolution which meets future requirements for HWO. As of August 2023, DST2 has begun operations to meet scientific milestones set by the principal investigators of NASA Strategic Astrophysics Technologies awards. Parallel to these priorities, work to determine contrast limitations will be performed

title: MARS 2020 ONBOARD PLANNER - UPDATE AND PREPARATIONS FOR OPERATIONS

description: The Mars 2020 mission has been developing an onboard planner (OBP) capability to enable the Perseverance rover to operate more efficiently. OBP enables the rover to reschedule activities in response to changes in environmental conditions (such as Mars being warmer than expected, or rover energy/State of charge being higher than expected) as well as execution variations (e.g. activities taking longer or shorter than expected. In this paper we describe the status of development of this capability including: testing and validation of the flight software, onboard commissioning, ground software to accommodate changing operations, operational readiness tests and training activities. Currently the M2020 onboard planner is scheduled to begin primary operations in October 2023

title: Multi-Agent 3D Map Reconstruction and Change Detection in Microgravity with Free-Flying Robots

description: Assistive free-flyer robots autonomously caring for future crewed outposts---such as NASA’s Astrobee robots on the International Space Station (ISS)---must be able to detect day-to-day interior changes to track inventory, detect and diagnose faults, and monitor the outpost status. This work presents a framework for multi-agent cooperative mapping and change detection to enable robotic maintenance of space outposts. One agent is used to reconstruct a 3D model of the environment from sequences of images and corresponding depth information. Another agent is used to scan the environment for inconsistencies against the 3D model. Change detection is validated using real image and pose data collected by Astrobee robots on Earth in a test environment and in space on the ISS. This work outlines the objectives, requirements, and algorithmic modules for the multi-agent reconstruction system, including recommendations for its use aboard future microgravity outposts.

description: We present a framework for developing shape error budgets for future large precision in-space assembled structures. Specifically, we target pin-jointed truss structures. We use as the key performance metric the surface root-mean-square error of the front surface of this pin-jointed truss. We apply this framework to an example 10-meter-diameter backing truss structure for the primary mirror of an optical space telescope.

title: Demonstration of Coronagraph Technology for High-Contrast Point Spectroscopy of ExoEarths

description: The planned Habitable Worlds Observatory (HWO) will be designed to find and characterize Earth-like planets in the habitable zones of Sun-like stars. This mission will require an instrument capable of making measurements of planet spectra at high contrast and small inner working angles. Previous demonstrations of existing coronagraph designs have not achieved these requirements at the 20% bandwidths or better required for full spectroscopic characterization, even in a laboratory environment. One technique that shows promise for improving bandwidth is the allocation of deformable mirror (DM) degrees of freedom to improve bandwidth by relaxing requirements on the size of the coronagraph’s focal plane correction region, or dark zone (DZ). In this work, we provide details and results of a laboratory demonstration of a wide-band coronagraph in NASA’s High-Contrast Imaging Testbed (HCIT) at the Jet Propulsion Laboratory (JPL). We show that a D-shaped region on one half of the focal plane can be corrected to a contrast of 4×10−10 in a 20% bandwidth using a simple Lyot coronagraph with two DMs. We also provide details of future plans to improve contrast and bandwidth by further reducing the dark region to just the light coupled into a single-mode fiber in the coronagraph’s focal plane.
