  • ExoMars science

    ExoMars science

    On 14 March at 09:31 GMT ExoMars 2016 will be launched from Baikonur onboard a Proton rocket.

    The joint European and Russian ExoMars mission will test key exploration technologies and search for evidence of methane and other rare gases in the Martian atmosphere. These gases could result from geological processes or they could be signatures of current biological activity on the planet.

    This film examines the two European science instruments on the ExoMars Trace Gas Orbiter (TGO) – CaSSIS and NOMAD. The high-resolution CaSSIS (Colour and Stereo Surface Imaging System) acts as the orbiter’s scientific eye. It is a telescope with a sophisticated detector that can provide colour and stereo images over a nine and a half kilometre wide strip. CaSSIS will examine recurring slope linea – dark lines on the surface of Mars at different times of the day over the planet’s seasons. These linea are believed to be associated with liquid brine. They increase in size during the Martian spring and summer and fade away during autumn and winter.

    NOMAD (Nadir and Occultation for MArs Discovery) will be the first high resolution instrument of its kind around the planet. It will observe information about Mars’ atmosphere by looking at the Sun during sunsets and sunrises. It contains three spectrometers – two working in the infrared and one in ultraviolet – and can identify trace gases in the atmosphere, such as methane. The presence of methane in Mars’ atmosphere could result from simple life forms like microbes.

    Sentinel-3A prepares for liftoff (4K timelapse)

    This timelapse video shows Sentinel-3A, from final preparations to liftoff on a Rockot launcher from the Plesetsk Cosmodrome in northern Russia, at 17:57 GMT (18:57 CET) on 16 February 2016.

    Sentinel-3A is the third satellite to be launched for Europe’s Copernicus environment monitoring programme.

    Designed as a two-satellite constellation – Sentinel-3A and -3B – the Sentinel-3 mission carries a series of cutting-edge instruments for systematic measurements of Earth’s oceans, land, ice and atmosphere. Over oceans, Sentinel-3 measures the temperature, colour and height of the sea surface as well as the thickness of sea ice. These measurements will be used, for example, to monitor changes in sea level, marine pollution and biological productivity. Over land, this innovative mission will monitor wildfires, map the way land is used, provide indices of vegetation state and measure the height of rivers and lakes.

  • ExoMars prepares for launch

    ExoMars prepares for launch

    The ExoMars 2016 spacecraft – consisting of the Trace Gas Orbiter (TGO) and the Schiaparelli entry, descent and landing demonstrator – is in Baikonur, Kazakhstan, preparing for its mid-March launch on a Russian Proton rocket.

    This joint European and Russian mission will test key exploration technologies and search for evidence of methane and other rare gases in the martian atmosphere. These gases could result from geological processes or they could be signatures of current biological activity on the planet. Three days before reaching Mars in October, Schiaparelli will separate from the orbiter and coast towards the planet in hibernation mode to reduce power consumption.

    This video covers the journey, the orbit of the Trace Gas Orbiter, the separation of the Schiaparelli lander and its 20 000 km/hour descent and eventual landing. It also contains filming at ESA’s European Space and Technology Centre (ESTEC) Mars Yard in the Netherlands. 

    Learning more about Mars’ water and environment will shed further light on this planet – while knowing the origin of its methane could finally answer the exciting question of whether there is life on Mars.

  • ESA Euronews: Building a Moon base

    ESA Euronews: Building a Moon base

    Jan Woerner, Director General of the European Space Agency, has a bold new vision for space exploration. “My intention is to build up a permanent base station on the Moon,” he tells Euronews from the agency’s main control room in Darmstadt. “Meaning that it’s an open station, for different member states, for different states around the globe.”

    Mankind has never had a permanent lunar presence, and so this new vision, that Woerner likes to call the ‘Moon village’, would represent a giant leap in space exploration.

    ESA Euronews: Bald ein Dorf auf dem Mond?

    Die Europäische Weltraumorganisation ESA will ein tollkühnes Projekt in Angriff nehmen: Sie will ein Dorf auf dem Mond bauen. Die permanente Station soll an dem Ort entstehen, an dem einst die Russen landeten und die Amerikaner erste Schritte machten. ESA-Chef Jan Woerner hat eine Vision: “Ich will eine permanente Mondstation bauen. Es wäre eine offene Station für mehrere Länder aus der ganzen Welt.”

    Die Apollo-Ära hat gezeigt, dass Träume Wirklichkeit werden können. Die Forscher damals hatten ein klares Ziel vor Augen: die Mondlandung. ESA-Astronaut Andreas Mogensen scheint zuversichtlich: “In den 1960er Jahren haben sie das innerhalb von zehn Jahren geschafft. Heute sind wir technologisch gesehen viel weiter. Wir können es also noch einmal machen.”

    Die Mondstation würde die Internationale Raumstation, ISS, ablösen. Sie wäre das neue gemeinsame Raumfahrt-Projekt, an dem alle teilnehmen könnten. “Die Amerikaner, die Russen, die Chinesen, die Inder und die Japaner werden mitmachen. Und andere Länder werden ebenfalls etwas beisteuern,” so Woerner.

    Tornare sulla Luna? La prossima tappa dell’esplorazione spaziale, dopo l’esperienza della Stazione Spaziale Internazionale, prevede molto di più. L’Agenzia spaziale europea ha un nuovo obiettivo: costruire una base permanente sulla luna.

    I russi furono i primi a lanciare una missione sulla luna mentre gli americani i primi a camminare sulla sua superficie. Oggi la luna continua ad essere al centro di ambiziose ricerche come ci conferma anche il direttore generale dell’Agenzia spaziale europea Jan Wörner. Una base internazionale, una stazione aperta ai diversi Stati membri dell’Agenzia e ai paesi di tutto il mondo.

    Un sogno animato dalla stessa passione che ha portato il primo uomo sulla Luna. Certo finora nessuno ha mai realizzato un progetto simile. Dalla missione spaziale Apollo sono stati fatti passi da gigante.

    O homem que está à frente da Agência Espacial Europeia (ESA) tem um ambicioso objetivo: construir uma base permanente na Lua. É no Centro Europeu de Astronautas em Colónia, na Alemanha, que estão a ser dados os primeiros passos nessa direção.

    Em 1959, os russos conseguiram aterrar uma nave não tripulada na Lua; dez anos mais tarde, os americanos passearam na sua superfície. Hoje em dia, o plano é ficar. _”O meu objetivo é construir uma base permanente na Lua. Uma estrutura aberta à participação de diferentes países”_, declara Jan Wörner, diretor geral da ESA. A ideia é criar um projeto global à semelhança da Estação Espacial Internacional.

    O Centro Europeu de Astronautas em Colónia organizou um workshop precisamente sobre como erguer uma espécie de pequena aldeia sobre a superfície lunar. A presença de certos metais, minerais e de água gelada pode representar um contributo valioso. Segundo Bernard Foing, diretor do Grupo Internacional de Exploração Lunar, _”a Lua tem imensos recursos. Encontrámos gelo nos polos, encontrámos áreas que estão quase constantemente expostas ao Sol. São zonas que nos podem fornecer recursos para utilizarmos na construção ou na manutenção da vida dos astronautas na base lunar.”_

Kelly and Kornienko are scheduled to land March 1, U.S. time (March 2, Kazakhstan time) in a Russian Soyuz spacecraft to complete a 340-day mission in which they collected valuable biomedical data on the long duration effects of weightlessness that will be used to formulate a human mission to Mars.

  • ISS reboost

    ISS reboost

    Ever wondered what happens inside the International Space Station during a reboost? ESA astronaut Tim Peake filmed inside during last week’s firing of the Progress thrusters.

    Even at 400 km, there are still enough molecules of the atmosphere to create some ‘atmospheric drag’, which causes the Station to drop by about 2 km a month. Because of this we need to raise the Station’s orbit every so often. On 17 February the engines of the Progress M-29M spacecraft that is docked to the aft port of the Zvezda module were fired for 11 minutes.

    The burn primarily focused on raising the Station’s perigee, making the orbit more circular.

    Pre-reboost: 398.2 x 407.4 km – inclination 51.64° – Period: 92.62min
    Post-reboost: 402.1 x 406.9 km – inclination 51.64° – Period: 92.66min

  • Philae facing eternal hibernation

    Philae facing eternal hibernation

    15 months after Philae made its historic landing on a comet, its legacy is enormous even if Rosetta’s lander is facing eternal hibernation.

    Mission teams are now looking ahead to the grand finale: making a controlled impact of the Rosetta orbiter on the comet next September.Rosetta arrived at Comet 67P/Churyumov–Gerasimenko on 6 August 2014 and Philae was delivered to the surface on 12 November. After touching down Philae bounced several times and completed 80% of its planned first science sequence before falling into hibernation. 

    A contact was made with the lander on 13 June and intermittent contacts were made up to 9 July. However the results of Philae mission are unique and complement all the science harvested by the orbiter Rosetta who is continuing its quest before being sent directly to the surface of 69P late September.

    Tim’s spacewalk highlights

    On 15 January ESA astronaut Tim Peake and NASA astronaut Tim Kopra stepped outside of the International Space Station to replace a failed power regulator and install cabling.

    The meticulously planned and executed sortie was stopped early after Tim Kopra reported a small amount of water building up in his helmet. The two Tims worked in close cooperation with each other to return to the Space Station, with NASA commander Scott Kelly and cosmonaut Sergei Volkov waiting inside to help them out of their suits.

    They left the confines of the weightless research laboratory at 12:48 GMT after their five-hour preparations to don their spacesuits and purge their bodies of nitrogen to avoid decompression sickness.

    Tim Kopra went first to the far end of the Station’s starboard truss, with Tim Peake following with the replacement Sequential Shunt Unit. Swapping the suitcase-sized box was a relatively simple task but one that needed to be done safely while the clock was ticking.

    With their main task complete, the Tims separated for individual jobs for the remainder of their time outside but was told by Mission Control to return to the airlock earlier than planned.

    The 4 hour 43 minute spacewalk was the first for a British astronaut. The spacewalk officially ended at 17:31 GMT when the Tims began the repressurisation of the Quest airlock.
