  • 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.

References 1 Preface P.1 Purpose a. This directive defines NASA’s obligation to avoid harmful forward and backward biological contamination under Article IX of the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies (the "Outer Space Treaty"), October 19, 1967. b. This directive specifically addresses the control of forward biological contamination of Mars and backward biological contamination of the Earth-Moon system associated with human presence in space vehicles intended to land, orbit, flyby, and return from Mars. c. The 1967 Outer Space Treaty provides in relevant part: “States Parties to the Treaty shall pursue studies of outer space, including the Moon and other celestial bodies, and conduct exploration of them so as to avoid their harmful contamination and also adverse changes in the environment of the Earth resulting from the introduction of extraterrestrial matter and, where necessary, shall adopt appropriate measures for this purpose.” NASA recognizes that the 1967 Outer Space Treaty (OST) sets forth legal requirements on U.S.

  • Investigating Mars' Atmosphere Using the NOMAD Instrument on The
    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.
