Bepicolombo - a Mission to Mercury
BEPICOLOMBO - A MISSION TO MERCURY ∗ R. Jehn , J. Schoenmaekers, D. Garc´ıa and P. Ferri European Space Operations Centre, ESA/ESOC, Darmstadt, Germany ABSTRACT BepiColombo is a cornerstone mission of the ESA Science Programme, to be launched towards Mercury in July 2014. After a journey of nearly 6 years two probes, the Magneto- spheric Orbiter (JAXA) and the Planetary Orbiter (ESA) will be separated and injected into their target orbits. The interplanetary trajectory includes flybys at the Earth, Venus (twice) and Mercury (four times), as well as several thrust arcs provided by the solar electric propulsion module. At the end of the transfer a gravitational capture at the weak stability boundary is performed exploiting the Sun gravity. In case of a failure of the orbit insertion burn, the spacecraft will stay for a few revolutions in the weakly captured orbit. The arrival conditions are chosen such that backup orbit insertion manoeuvres can be performed one, four or five orbits later with trajectory correction manoeuvres of less than 15 m/s to compensate the Sun perturbations. Only in case that no manoeuvre can be performed within 64 days (5 orbits) after the nominal orbit insertion the spacecraft will leave Mercury and the mission will be lost. The baseline trajectory has been designed taking into account all operational constraints: 90-day commissioning phase without any thrust; 30-day coast arcs before each flyby (to allow for precise navigation); 7-day coast arcs after each flyby; 60-day coast arc before orbit insertion; Solar aspect angle constraints and minimum flyby altitudes (300 km at Earth and Venus, 200 km at Mercury). -

The two SWIFTS (Stationary-Wave Integrated Fourier first types need moving mirrors to scan spectrally Transform Spectrometer) represents a family of very thus adding complexity and failure risk in space. The compact spectrometers based on detection of interesting solution of AOTF, without moving part standing waves for which detectors play itself a role (only piezo) is however limited in resolution to a few in the interferential detection mechanism. The aim of cm-1 due to limitation in monocrystal size (fragile). this paper is to illustrate how these spectrometers can Strong limitations of these instruments in terms of be used to build efficient imaging spectrometers for performances (spectral & spatial resolution and range, planetary exploration inside dm3 instrumental volume. S/N ratio) come from their already large mass, The first mode (SWIFTS) is devoted to high spectral volume, and power consumption. Further increasing resolving power imaging (R~10000-50000) for one of these characteristics will be at the cost of even 40x40 pixels field of view. The second mode bigger instruments. -

The Cassini Ultraviolet Imaging Spectrograph (UVIS) is part of the remote sensing payload of the Cassini orbiter spacecraft. UVIS has two spectrographic channels that provide images and spectra covering the ranges from 56 to 118 nm and 110 to 190 nm. A third optical path with a solar blind CsI photocathode is used for high signal-to-noise-ratio stellar occultations by rings and atmospheres. A separate Hydrogen Deuterium Absorption Cell measures the relative abundance of deuterium and hydrogen from their Lyman-α emission. -
VIRTIS/Venus Express Summary
VIRTIS for Venus Express Pierre Drossart# and Giuseppe Piccioni&, December 2002 #LESIA, Obs. Paris and &IASF,Rome VIRTIS (Visible and Infrared Thermal Imaging Spectrometer) is a complex instrument initially devoted to the remote sensing study of comet Wirtanen on the Rosetta mission, at wavelengths between 0.3 and 5 mm. The focal planes, with state of the art CCD and infrared detectors achieve high sensitivity for low emissivity sources. Due to the high flexibility of the operational modes of VIRTIS, these performances are also ideally adapted for the study of Venus atmosphere, both on night and day sides. VIRTIS is therefore aimed to provide a 4- dimensional study of Venus atmosphere (2D imaging + spectral dimension + temporal variations), the spectral variations permitting a sounding at different levels of the atmosphere, from the ground up to the thermosphere. The infrared capability of VIRTIS is especially well fitted to the thermal sounding of the night side atmosphere (Taylor et al, 1997), which give a tomography of the atmosphere down to the surface. Precursors: First attempts of imaging spectrometry on the Venus night side from space in the near infrared were made by NIMS/Galileo (Figure 1) in 1990 (Carlson et al, 1990) and VIMS/Cassini in 1999 (Baines et al, 2000). These fast fly-bys gave an idea of how powerful this method of investigation could be at Venus. Unfortunately, the limited duration of the fly- bys allowed only limited investigations, in particular on the meteorological evolution of the clouds. Observation of Venus with a new generation imaging spectrometer like VIRTIS would provide a unique opportunity to continue these investigations on an extended basis. -
The Science Return from Venus Express the Science Return From
The Science Return from Venus Express Venus Express Science Håkan Svedhem & Olivier Witasse Research and Scientific Support Department, ESA Directorate of Scientific Programmes, ESTEC, Noordwijk, The Netherlands Dmitri V. Titov Max Planck Institute for Solar System Studies, Katlenburg-Lindau, Germany (on leave from IKI, Moscow) ince the beginning of the space era, Venus has been an attractive target for Splanetary scientists. Our nearest planetary neighbour and, in size at least, the Earth’s twin sister, Venus was expected to be very similar to our planet. However, the first phase of Venus spacecraft exploration (1962-1985) discovered an entirely different, exotic world hidden behind a curtain of dense cloud. The earlier exploration of Venus included a set of Soviet orbiters and descent probes, the Veneras 4 to14, the US Pioneer Venus mission, the Soviet Vega balloons and the Venera 15, 16 and Magellan radar-mapping orbiters, the Galileo and Cassini flybys, and a variety of ground-based observations. But despite all of this exploration by more than 20 spacecraft, the so-called ‘morning star’ remains a mysterious world! Introduction All of these earlier studies of Venus have given us a basic knowledge of the conditions prevailing on the planet, but have generated many more questions than they have answered concerning its atmospheric composition, chemistry, structure, dynamics, surface-atmosphere interactions, atmospheric and geological evolution, and plasma environment. It is now high time that we proceed from the discovery phase to a thorough -

The Visible and InfraRed Thermal Imaging Spectrometer (VIRTIS) aboard ESA’s Venus Express mission measured, inter alia, the nightside thermal emission of Venus in the near infrared atmospheric windows between 1.0 and 1.2 µm. These data can be used to determine information about surface properties on global scales. This requires a sophisticated approach to understand and consider the effects and interferences of different atmospheric and surface parameters influencing the retrieved values. In the present work, results of a new technique for retrieval of the 1.0 – 1.2 µm – surface emissivity are summarized. It includes a Multi-Window Retrieval Technique, a Multi-Spectrum Retrieval technique (MSR), and a detailed reliability analysis. The MWT bases on a detailed radiative transfer model making simultaneous use of information from different atmospheric windows of an individual spectrum. -

This article is published with open access at Springerlink.com Abstract MicrOmega is a near-IR hyperspectral microscope designed to characterize in situ the texture and composition of the surface materials of the Hayabusa2 target aster- oid. MicrOmega is implemented within the MASCOT lander (Ho et al. in Space Sci. Rev., 2016, this issue, doi:10.1007/s11214-016-0251-6). The spectral range (0.99–3.65 µm) and the spectral sampling (20 cm−1) of MicrOmega have been chosen to allow the identification of most potential constituent minerals, ices and organics, within each 25 µm pixel of the 3.2 × 3.2mm2 FOV. Such an unprecedented characterization will (1) enable the identifica- tion of most major and minor phases, including the potential organic phases, and ascribe their mineralogical context, as a critical set of clues to decipher the origin and evolution of this primitive body, and (2) provide the ground truth for the orbital measurements as well as a reference for the analyses later performed on returned samples. 1 Introduction The Hayabusa mission, launched May 9, 2003, and samples returned to Earth by June 13, 2010, enabled the study of 25143 Itokawa, an S class asteroid (Fujiwara et al. -

The UVS instrument consists of a grating spectrometer (UVS-G), an absorption cell photometer (UVS-P) and an electronics unit (UVS-E). The UVS-G features a flat-field type spectrometer measuring emissions in the FUV and MUV range between 110 nm and 310 nm with a spectral resolution of 2–3 nm. The UVS-P is a photometer separately detecting hydrogen (H) and deuterium (D) Lyman α emissions by the absorption cell technique. They take images using the spin and orbital motion of the spacecraft. The major scientific objectives of the UVS experiment at Mars and the characteristics of the UVS are described. The MUV spectra of geocoronal and interplanetary Lyman α emissions and lunar images taken at wavelength of hydrogen Lyman α and the background at 170 nm are presented as representative examples of the UVS observations during the Earth orbiting phase and the Mars transfer phase. 1. Introduction objectives. The ultraviolet spectra of the Martian airglow Due to a weak or no intrinsic magnetic field on Mars, the were obtained by the Mariner 9 ultraviolet spectrometer solar wind plasma can deeply penetrate into the Martian experiment (Barth et al., 1972).
