title: International Mars Ice Mapper Mission: A step forward to map near-surface water ice and its atmospheric interactions and to prepare for future robotic and human surface science

description: The International Mars Ice Mapper (I-MIM) mission concept has been conceived by the Italian, Canadian, Japanese, and US Space Agencies partners (ASI, CSA, JAXA, and NASA) with the primary goal of recognizing ice deposits and accessible water in the upper 0-10 m of the Martian subsurface, characterizing its overburden, and studying subsurface/surface/atmospheric exchanges. I-MIM Measurement Definition Team (MDT): The Agency Partners competitively selected the MDT to define the core measurements for the mission’s primary payload, to suggest possible augmentations, and to develop a concept of operations. The MDT released a Final Report [1], concluding that the mission’s primary instrument, a polarimetric Synthetic Aperture Radar (SAR) centred at 930 MHz, would satisfy initial mission objectives, while recommending that the concept team consider the inclusion of complementary payloads identified as highest priority: a Very High Frequency (VHF) radar sounder (100-200 MHz), a High-Resolution optical imager, and a sub-millimetre sounder for atmospheric profiling to expand the capabilities of I-MIM to undertake high-priority science investigations. Members of the MDT subsequently developed traceability matrices for these highest priority instruments in an addendum to the MDT Report [2].

title: Real time data-based wind model for a Venus Aerobot: development and testing

description: The surface of Venus is characterized by extreme temperature and a crushing pressure. However, at altitudes between 51 to 62 km, conditions resemble Earth's surface, making it an ideal location for a proposed mission concept that involves deploying a balloon with a suspended science gondola, known as an aerobot. Due to the planet's extreme wind conditions, with gusts reaching up to 100 m/s, and the complexities of balloon dynamics in the atmosphere, detailed models of wind gusts are critical to predict the aerobot’s dynamics. Unfortunately, previous missions have only collected surface wind data and vertical gusts, leaving horizontal gusts data missing. The goal of this paper is to present the development of a systematic method to generate wind gust model capable of capturing the highly non-stationary and random characteristics of wind gusts from real-time data. The model is fitted to data collected during terrestrial flight tests, so it can be used in predictive simulations of the Venus aerobot behavior in Earth field experiments. The proposed approach relies on a set of stochastic differential equations, specifically a bidimensional Ornstein-Uhlenbeck process, to accurately represent the autocorrelation function and probability density function of a measured wind signal. The first function captures the “memory effect” of the signal, while the second one serves as a tool for reproducing the observed instantaneous distribution of wind direction and speed. The proposed method was tested using real-world wind speed measurement data collected by Jet Propulsion Laboratory during flight tests in the Mojave Desert. An extended Kalman filter was used to process the real-time wind signal captured by measurement instruments before incorporating it into the model. This filter adeptly captures the dynamics of an atmospheric balloon, and efficiently fuses data from inertial measurement units and wind measurement instruments. Results indicate that the proposed method is simple to implement and can accurately capture simultaneously the autocorrelation and probability distribution of wind speed measurement data, and holds promise as a tool for design of future Venus aerobots.

title: Dynamics and Control of Smart Boomerangs

description: Boomerangs are devices historically known for their capability of returning to their thrower after being launched into the air. However, their trajectory is heavily influenced by environmental and initial conditions, with the latter including throwing the boomerang with the correct roll angle and imparting adequate linear and rotational speed. To expand the capabilities of classic boomerangs, the concept of a ’Smart Boomerang’ has been proposed. This boomerang adjusts its flight control surfaces or other internal characteristics to achieve much more complex trajectories than those feasible with standard boomerangs. It can even end its flight at a different location from where it was launched, which is useful if it is to be retrieved by a vehicle in motion. On planets with atmospheres, such a smart boomerang could be launched automatically from an atmospheric platform, such as a balloon on Venus or Titan, or from a ground platform, returning to the platform at its new location. Thus, it can perform observations or even sampling. This has some advantages and disadvantages compared to a drone, such as a helicopter. In this paper, we describe a simulation tool developed to predict a boomerang’s trajectory, given its design parameters and launch conditions. To further analyze the capabilities of this system, nonlinear equations of motion for boomerang flight dynamics have been developed and tested in simulation. The results were validated with experimental tests. The models further allowed us to analyze wind effects. A PID controller was then implemented with the intent to complete path- following missions, and different mechanisms of autonomously achieving a mid-air trajectory change were compared. A preliminary study of the hardware requirements for state estimation was conducted, highlighting the need of solutions like Visual-Inertial Odometry to accurately measure the probe’s position. Finally, a design solution is proposed to achieve trajectory changes by means of rotating the boomerang’s wings, and considerations about the state estimation problem are presented. In summary, this work expands the concept of Smart Boomerangs by exploring their dynamics and the possibility of controlling their trajectories. The developed model works as an alternative yet complementary tool to experimental tests as it enables gathering essential data about the feasibility of trajectory control and boomerangs’ design in time- and cost-effective manners.

title: Design, Prototype, and Performance Assessment of an Autonomous Manipulation System for Mars Sample Recovery Helicopter

description: This paper presents the design, prototype, andtesting of a 150 g (current best estimate) manipulation systemthat enables Mars Sample Recovery Helicopter (SRH) conceptto autonomously pickup, stow, and drop-off Returnable SampleTube and Glove Assemblies (RGAs) on the surface of Mars nextto the Sample Retrieval Lander (SRL). It consists of a 3 DOFplanar Robotic Arm (RA), a novel 2 DOF Gripper withcompliant fingers, and a Stow Mechanism. Within the plannedMars Sample Return (MSR) campaign, two SRHs would operatein parallel to retrieve and transfer total of 10 RGAs (146g each)to the SRL, as the backup to the Perseverance Rover. Once SRHarrives at the target pickup location, the RA places the Gripperprecisely over the RGA. The gripper grabs and picks up RGAsusing a linkage based non-back-drivable mechanism and itscompliant fingers. Subsequently, the RA is secured into the stowfeatures, following dislodging rocks and pebbles, by goingthrough a specific sequence of joint trajectories. This ensures theRA and RGA are stable and secure during transit to the SRLwhile all Manipulation System actuators are powered off. Thewhole sequence of manipulation is performed autonomouslyusing feedback of a pair of stereo-cameras and absoluteencoders. Experimental evaluation of the Manipulation Systemperformance has proved its robustness and consistency insuccessful RGA pickup, stow, and drop-off.

title: Design and prototyping of braodband metasurface scalar phase masks for high-contrast imaging

description: NASA’s future Habitable Worlds Observatory (HWO) will enable the direct detection and characterization of Earth-like planets around Sun-like stars using high-contrast imaging. One of the most promising approaches to achieve this goal is to use a coronagraph. A good candidate for implementation in HWO is the vortex coronagraph, which is featured in both original mission concepts HabEx and LUVOIR. However, at the high contrast levels required for HWO (1e-10), the polarization dependency and chromatic leakage of the vector vortex coronagraph becomes a limiting factor, making it challenging to perform wavefront control in both polarizations simultaneously. Filtering one polarization or splitting the two polarizations provide possible solutions, but at the expense of reducing the throughput by a factor of 2, or doubling the number of optics in the instrument. An alternative approach is to use a scalar vortex phase mask, which imprints the same phase ramp onto both polarizations. However, the broadband performance of the scalar vortex has to be improved to meet the 1e-10 contrast goal of HWO. Metasurfaces present a promising technology for achromatizing scalar vortex coronagraphs, because they allow for more design freedom in a single layer of constant thickness compared to scalar vortex phase masks based on variable thickness of a dielectric substrate. Here, we present our progress in developing metasurface scalar vortex phase masks. We present updated broadband designs of scalar metasurface phase masks of different topographies, and simulate their performance with appropriate simulation tools. We also discuss first manufacturing attempts at such masks, and outline the next steps needed to push their performance towards the levels required for HWO.

title: International Mars Ice Mapper Communication System

description: The Italian Space Agency (ASI) and Thales Alania Space in Italy (TAS-I) in the context of the International Mars Ice Mapper (I-MIM) mission and in collaboration with the NASA Jet Propulsion Laboratory (JPL) are studying an innovative multi-band Communication Subsystem designed to deliver scientific data of at least 500 Gbit per day from the mission’s three elements (E): a main orbiter (E1), a demonstration lander (E2), and a freeflying smallsat (E3). The planned E1 instruments are a polarimetric synthetic aperture radar (SAR) in L-band, a Very High Frequency (VHF) sounder, and a submillimeter sounder. The E3 orbiter would carry a high-resolution imager. All of these next-generation sensors would generate high volumes of data and require large data-rate (&gt;100 Mbps) acquisition. With analysis and definition of mission scenarios during its concept phase, the mission team has identified two main communication links. The Direct to Earth (DTE) link would deliver the science data and telecommand and telemetry at a high data rate primarily in Ka-bands (32 GHz) and in X-bands, with data transmission above 10 Mbps with Deep Space Network ground stations. The preliminary defined architecture anticipates that the 6-m aperture Large Deployable Reflector antenna (LDR) would support both DTE and the SAR instrument. The other main link under definition is the Proximity Link, which would support the relay of science data from the E3 smallsat to the main orbiter through X band for subsequent DTE links. This proximity link would potentially be available to relay data from future Mars orbiters and next-generation rovers and landers on the surface. A UHF proximity link would be onboard to relay data from legacy users on the surface already at Mars, as well as potentially support I-MIM’s E2 lander. While both UHF and X-band are the primary considered bands for the proximity link, the mission team is also considering Ka-band and optical links to take into account the evolution of future exploration missions. With the goal of identifying and characterizing accessible, near-surface water ice in the mid latitudes of Mars, the I-MIM mission is a multilateral collaboration being developed by the Agenzia Spaziale Italiana (ASI), the Canadian Space Agency (CSA), the Japan Aerospace Exploration Agency (JAXA), and the National Aeronautics and Space Administration (NASA).

title: Modeling and Analysis of Tethered System Dynamics for Venus Aerobots and Towed Probes

description: Venus, the Earth’s nearest planetary neighbor, provides a unique natural laboratory for studying plan- etary and climate processes. Despite sharing similarities with Earth, an out-of-control greenhouse effect has made it the hottest planet in the solar system. Because of its corrosive atmosphere, high temperatures, and pressures, Venus’s atmosphere represents an extreme and challenging environment for scientific explo- ration. One of the most promising approaches to studying the Venusian atmosphere and its surface is using an autonomous scientific balloon, also called “aerobot”, which could navigate the atmosphere using buoy- ancy force to maintain a certain altitude (around 52 km), where temperatures and pressures are comparable to Earth’s. NASA’s Jet Propulsion Laboratory is developing missions to explore and survive the Venusian harsh environment. The paper describe modeling and simulation developed to support the technology de- velopment of the Venus Aerobot mission, demonstrating how an efficient and user-friendly flight mechanics simulator could be extremely helpful in capturing and testing various systems architectures with different purposes. The simulator implemented two different, but complementary, modeling approaches of the tether dynamics, specifically a Lumped Mass approach and the DeNOC (Decoupled Natural Orthogonal Matrix) recursive approach. In addition, a stochastic wind model was included. The simulator can also reproduce and analyze the behavior of towed atmospheric probes and assess their ability to change the trajectory of the entire system by exploiting aerodynamic forces acting on the towed body, which could be trailing at kilometers of distance below the balloon. The models used in the simulator demonstrated the feasibility of tracking the trajectory of a towed body using a micro aerial vehicle capable of flying autonomously. These mission architectures would allow the collection of samples from Venus’s surface and their return to the lofting system. The simulator described in this paper enables preliminary system-level analysis and the understanding of the entire flight chain dynamics, encompassing inflated balloons, gondolas suspended by tethers, and bodies towed with long tethers. Future studies will explore balloon and body aerodynamics in more detail, focusing on controlling the aerobot trajectory vertically and laterally using aerodynamic forces on towed bodies.
