  • Oxygen discovery in a comet | BIRA-IASB
    system How is it then possible to find abundant oxygen gas in a comet Comet 67P Churyumov Gerasimenko as photographed by Rosetta In its atmosphere a large fraction of oxygen gas has been discovered ESA OSIRIS The paper Abundant molecular oxygen in the coma of comet 67P Churyumov Gerasimenko by A Bieler et al reports on this discovery and discusses possible explanations The simplest explanation is to assume that the oxygen was there from the moment the comet was formed Since comets stay in the very cold outer regions of the solar system any chemical reactions would be extremely slow so that it could be preserved up to now But this raises new questions Was the O 2 produced while the planets formed Was it already present in the gas and dust cloud from which the Sun and the planets condensed Astronomers do not observe oxygen in typical proto planetary gas and dust clouds The DFMS mass spectrometer that discovered oxygen gas in the comet atmosphere Rosetta ROSINA DFMS consortium There is one alternative explanation O 2 could be created in the ices in a comet during its 4 billion year stay in the outer solar system by bombardment with cosmic rays These are very energetic atoms that zip through the galaxy There are not many of them but because of their high energy and because 4 billion years is a very long time it seems that enough O 2 can be produced The scientists however are very prudent in drawing conclusions there is a lot of uncertainty about the detailed low temperature chemistry and the flux of cosmic rays over the past 4 billion years is not well known which makes it hard to prove or disprove this alternative explanation A typical DFMS mass spectrum around mass 32 showing

  • Argon ontdekt in de atmosfeer van een komeet
    sonde in de atmosfeer van de komeet 67P Churyumov Gerasimenko Deze ontdekking hebben we te danken aan de massaspectrometer DFMS van het instrument ROSINA Dit instrument aan boord van Rosetta werd op punt gesteld in samenwerking met de wetenschappers en ingenieurs van het Koninklijk Belgisch Instituut voor Ruimte Aeronomie BIRA De hoge massaresolutie van dit instrument laat toe twee varianten van argon te detecteren de isotopen 36 Ar en 38 Ar De detectie van argon zal de wetenschappers helpen om de processen die aan het werk zijn tijdens de vorming van kometen beter te begrijpen Het lijkt erop dat de argonatomen in de zeer koude omstandigheden tijdens de komeetvorming ongeveer 230 C gemakkelijk gemakkelijk ingebed worden in de structuur van het ijs in de komeetkern Deze ontdekking vormt een extra argument in de discussie over de verschillende ingrediënten die kometen naar de Aarde gebracht hebben tijdens de vorming van ons zonnestelsel Deze nieuwe resultaten getuigen van de vluchtigheid van dit gas veel vluchtiger dan water eerder vergelijkbaar met de vluchtigheid van stikstof N 2 links Typische massaspectra voor de detectie van 36Ar en 38Ar door hetinstrument ROSINA DFMS Men kan deze stoffen slechts onderscheiden dankzij de hoge massaresolutie van het

  • découverte d'argon sur une comète

  • ISS rover METERON
    answered that there are several very interesting experiments but as an engineer I am looking forward to control the rovers on the ground from the ISS The astronaut will drive different rovers while orbiting the Earth at 400 km altitude One of them is Eurobot a rover developed within the frame of the METERON project for which the Belgian User Support and Operations Centre B USOC is supporting the preparation and execution of the operations on the ISS B USOC is also responsible for the THOR experiment during which Andreas will take pictures of thunderstorms from space METERON METERON Multi Purpose End To End Robotic Operation Network is developing the communication networks robot interfaces and hardware to operate robots from a distance in space and should enable Europe in the future to explore the moon Mars and other planetary surfaces The International Space Station is used as testbed with astronauts controlling rovers on Earth The project includes collaboration between the ISS space agencies NASA ESA Roscosmos and DLR developing the necessary technology for commanding a robot on Earth by an astronaut on the ISS The engineering and operations teams of B USOC are delivering operational support to the METERON project by ensuring the connectivity between ISS and ESA facility where the robot is located THOR THOR will observe atmospheric luminous phenomena related to large thunderstorms using optical cameras Andreas Mogensen will take images of giant lightning and thunder clouds through the windows of the International Space Station The experiment objectives are closely related to ASIM Atmosphere Space Interaction Monitor a future Danish payload of the ISS European Module designed to better analyse those phenomena ESA delegated the overall operational responsibility for ASIM to B USOC B USOC B USOC is a services centre providing engineering and operational support for space
