  • Prof Xavier Maldague
    We were proud to announce the guest lecture by professor Xavier Maldague of the Electrical and Computing Engineering Department at the Université Laval, Québec in Canada.

    Infrared vision is an interesting tool to assess condition state and authenticity of art pieces and cultural heritage structures. In this presentation, a brief introduction of inspection principles using infrared vision was presented: both infrared non thermal and thermal approaches were discussed.

    The talk was completed by several case studies our team have been involved with. Case studies presented included ancient wood panel in Canada; frescoes, tiled walls and old buildings and churches in Italy. A brief report concerning our current involvement in the Scan Pyramid Project launched by the HIP Institute, University of Cairo and Ministry of Antiquities of Egypt was discussed as well.

  • Space exploration of Venus, Mars and beyond using (relatively) high resolution infrared spectroscopy
    By Dr Ir Ann Carine Vandaele, Royal Belgian Institute for Space Aeronomy

    Mars has been monitored for decades now, either from Earth using large telescopes and sensitive spectrometers, from the Hubble Space Telescope, from rovers or platforms on the surface of Mars and of course from instruments in orbit around the planet. The last atmospheric mission to the Red planet, the ESA/ROSCOSMOS ExoMars Trace Gas Orbiter, launched in 2016, just started its Science phase in April 2018. On board, two spectrometers’ suites will probe the atmosphere.

    The Venus Express mission observed the atmosphere of Venus down to its surface with a wide range of spectrometers. New missions are being prepared to go back to Venus or to the moons of Jupiter. Ground-based and space telescopes in Earth orbit are also being improved or built, providing us with spectra of a wide variety of objects. The James Webb Space Telescope will (soon) replace the Hubble Space Telescope, although its launch has again been postponed. Missions to observe exoplanets are being prepared, with CHEOPS to be launched in 2019, followed by PLATO and ARIEL.

    Dr Ann Carine Vandaele reviewed the capabilities in terms of spectral coverage and resolution of these space missions and instruments, showing that although their resolutions might not be as high as spectroscopists might wish, they allow for very interesting science.
