The ExoFit Rover field trial - simulating ExoMars Rosalind Franklin Rover operations Matthew Balme1, Suzanne Schwenzer1, Ben Dobke2, Martin Azkarate3, Delfa Juan4, Duvet Ludovic4, and the ExoFit team* 1Open University, School of Physical Sciences, Milton Keynes, United Kingdom of Great Britain and Northern Ireland ([email protected]) 2Airbus Defence and Space Ltd, Gunnels Wood Road, Stevenage SG1 2AS, UK 3European Space Agency, ESTEC, Keplerlaan 1, 2201 AZ Noordwijk, The Netherlands 4European Space Agency, ECSAT, Fermi Avenue, Harwell Campus, Didcot, OX11 0FD, UK *A full list of authors appears at the end of the abstract The ExoMars 2022 Rosalind Franklin Rover will search for signs of past and present life on Mars, and study the water/geochemical environment in the shallow subsurface. The mission will launch in autumn 2022, together with the Kazachok surface platform, and includes an analytical and imaging comprehensive instrument suite and a sampling drill that can penetrate to ~ 2 m beneath the surface.1 The mission will land in Oxia Planum, an area of Mars containing sedimentary rocks with high clay-mineral content2. To prepare for ExoMars surface operations, an ExoMars-Like Field Trial (ExoFiT) using an instrumented ExoMars-like Rover has been performed, building on past field trial experience3,4. The aim of the trial was to understand how the ExoMars Rover and its instrument payload would be used to meet the ExoMars Rover science goals, when operated by a realistic science team. Also, to provide ‘lessons-learned’ to improve and inform operations planning for the real mission. The first part of the trial occurred in the Tabernas desert, Spain, in 2018. The Tabernas site contains a sequence of sedimentary rocks and hosts a variety of geomorphological and mineralogical features typical of clay-rich desert surfaces. The second part of the trial was performed in the Atacama desert, Chile, in 2019. The Atacama site has a very Mars-like environment, consisting of a dry desert pavement made of gravel and boulders, interspersed with finer-grained, coarse sand patches. The ExoFiT Rover and lander platform were supplied and operated by AIRBUS and have similar capabilities and dimensions to the ExoMars Rover hardware. The ExoFiT Rover included emulators for the ExoMars’ PanCam5 (colour stereo panoramic camera), CLUPI6 (close-up camera), WISDOM7 (ground-penetrating RADAR), ISEM8 (infrared reflectance spectrometer), RLS9 (Raman spectrometer), and de-mounted emulator of the ExoMars Rover drill instrument. In both trials, the rover was controlled from a Remote Control Centre (RCC) in the UK. The RCC team included members of several ExoMars instrument teams, planetary scientists, engineers, and ESA observers. In all cases, the RCC was kept “blind” and controlled the Rover as if it were on Mars, using only Mars-like orbital remote sensing assets, and data returned to the RCC from the Rover itself. Realistic rover operations constraints (e.g., daily operating time and data budget) and tactical planning uplink/downlink time constraints were used. The astrobiological “mission success” science goal for ExoFiT was to return a drill core sample from a fine-grained sedimentary material laid down in water, or that had undergone deposition of minerals from groundwater, and so had once been both a habitable environment and one in which biosignatures could have been preserved. Here, we present a description of the ExoFiT trials including tactical and strategic planning, pre- mission orbital mapping, and analysis of science return. We assess whether we were able to meet the ExoFit astrobiological science goal, and summarise key lessons learned for the real ExoMars Rover mission. References cited 1. Vago, J. L. et al.

  • Outline of Aurora Funding

    Outline of Aurora Funding

    Outline of Aurora funding The £3 million from the Aurora Science Programme has gone to the following 17 academics and individual scientists working at UK research organisations: 1. An improved understanding of Mars photochemistry using NOMAD and ACS measurements – Professor Paul Palmer, Edinburgh University - £73,442 The proposal aims to develop the existing photochemistry (the chemistry effects of light) to prepare for measurements collected by the NOMAD and ACS instruments aboard the Trace Gas Orbiter. They will develop the chemical mechanism so it can be used to interpret observed variations of atmospheric gases on Mars. 2. Dust storms and the dust transport cycle: their impact on the Martian climate in a multi annual reanalysis of MCS, THEMIS and TGO/ACS data – Professor Peter Read, Oxford University - £346,592 The proposal aims to improve our understanding of the Martian dust cycle, its impact on climate and the physical features of the Martian surface. Using a new approach towards analysing daily variations in the Martian atmosphere it is proposed to extend this dataset using measurements of the Martian atmosphere from the Mars Reconnaissance Orbiter and Mars Odyssey missions in orbit around Mars, and from the Atmospheric Chemistry Suite (ACS) on ESA's Trace Gas Orbiter mission when they become available. This may be useful for future spacecraft operations at the Martian surface, as well as to improve our understanding of both the present and past states of the Martian climate. 3. ExoMars TGO Guest Investigator Support – Dr Matt Balme, Open University - £56,367 This proposal seeks funding for a Guest Investigator position on ESA's ExoMars Trace Gas Orbiter mission.

[email protected] Abstract of the Proposed Talk: One of the goals of IPPW has been to bring about international collaboration. Establishing collaboration, especially in the area of EDL, can present numerous frustrating challenges. IPPW presents opportunities to present advances in various technology areas. It allows for opportunity for general discussion. Evaluating collaboration potential requires open dialogue as to the needs of the parties and what critical capabilities each party possesses. Understanding opportunities for collaboration as well as the rules and regulations that govern collaboration are essential. The authors of this proposed talk have explored and established collaboration in multiple areas of interest to IPPW community. The authors will present examples that illustrate the motivations for the partnership, our common goals, and the unique capabilities of each party. The first example involves earth entry of a large asteroid and break-up. NASA Ames is leading an effort for the agency to assess and estimate the threat posed by large asteroids under the Asteroid Threat Assessment Project (ATAP).

Goodyear,* Ghanghoon Paik,* Guanwei. He,* Peter C. Scarcella,* Mollik Nayyar,* Matthew J. Shaw* We present the methods and results of the Astrodynamics Research Group of Penn State (ARGoPS) team in the 2017 Astrodynamics Specialist Conference Student Competition. A mission (named Minerva) was designed to investigate Asteroid (469219) 2016 HO3 in order to determine its mass and volume and to map and characterize its surface. This data would prove useful in determining the necessity and usefulness of future missions to the asteroid. The mission was designed such that a balance between cost and maximizing objectives was found. INTRODUCTION Asteroid (469219) 2016 HO3 was discovered recently and has yet to be explored. It lies in a quasi-orbit about the Earth such that it will follow the Earth around the Sun for at least the next several hundred years providing many opportunities for relatively low-cost missions to the body. Not much is known about 2016 HO3 except a general size range, but its close proximity to Earth makes a scientific mission more feasible than other near-Earth objects. A Request For Proposal (RFP) was provided to university teams searching for cost-efficient mission design solutions to assist in the characterization of the asteroid and the assessment of its potential for future, more in-depth missions and possible resource utilization. The RFP provides constraints on launch mass, bus size as well as other mission architecture decisions, and sets goals for scientific mapping and characterization.

Osinski,14 and the PanCam Team Abstract The scientific objectives of the ExoMars rover are designed to answer several key questions in the search for life on Mars. In particular, the unique subsurface drill will address some of these, such as the possible existence and stability of subsurface organics. PanCam will establish the surface geological and morphological context for the mission, working in collaboration with other context instruments. Here, we describe the PanCam scientific objectives in geology, atmospheric science, and 3-D vision. We discuss the design of PanCam, which includes a stereo pair of Wide Angle Cameras (WACs), each of which has an 11-position filter wheel and a High Resolution Camera (HRC) for high-resolution investigations of rock texture at a distance. The cameras and electronics are housed in an optical bench that provides the mechanical interface to the rover mast and a planetary protection barrier.

    Investigating Mars’ atmosphere using the NOMAD instrument on the ExoMars Trace Gas Orbiter Supervision team: Dr Manish Patel, Dr Stephen Lewis, Dr Jonathon Mason External supervisor: N/A Lead contact: [email protected] Description: This project provides the opportunity to be directly involved in an active space mission and play a key role in the preparation and exploitation of results from a spaceflight instrument on the ESA ExoMars Trace Gas Orbiter mission, which is currently in orbit around Mars. The project will involve supporting work on: - Continued development of a radiative transfer model of the martian atmosphere in preparation for ExoMars - Characterisation of Flight Spare instrumentation and data interpretation from mid-cruise checkouts - Preparation of new techniques for retrieval of atmospheric species - Exploitation of data returned from the NOMAD-UVIS instrument This mission is aimed at furthering our understanding of the composition and dynamics of the martian environment, through the measurement of trace gases such as ozone and methane in the martian atmosphere from orbit. The project relates to the UVIS channel of the NOMAD instrument; UVIS is an optical spectrometer led by the Open University to measure solar radiation travelling through the martian atmosphere at UV and visible wavelengths, in order to detect and map the presence of ozone, dust and ice clouds in the atmosphere of Mars in unprecedented detail. This project will involve scope for a wide range of potential research from instrument testing through to exploitation of real spaceflight instrument data. The focus of the project is on the retrieval of ozone and aerosol abundance and properties from spectra that will be returned from the UVIS instrument.
