Na een tocht van 3 miljard km die ruim zeven jaar heeft geduurd, is ESA\u2019s Huygens-sonde klaar om te landen op Titan, de grootste maan van Saturnus.<\/p>\n<\/div>\n<p>Op eerste kerstdag komt Huygens los van Cassini, de orbiter waar hij aan vast zit. Daarna schiet de kleine, schotelvormige sonde pijlsnel naar de in nevelen gehulde maan, waarbij hij zeven keer per minuut om zijn as draait.<\/p>\n<p>Twintig dagen lang is er radiostilte, tot de timer aan boord zegt dat het tijd is om de communicatie te herstellen. Op 14 januari stort Huygens zich in de bovenste atmosfeer van Titan met een snelheid van rond de 6 km per seconde. Dat is tien keer zo snel als de Concorde.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2004\/11\/Huygens_entering_Titan_s_atmosphere2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2004\/11\/huygens_entering_titan_s_atmosphere2\/17903380-2-eng-GB\/Huygens_entering_Titan_s_atmosphere.jpg\" alt=\"Huygens entering Titan&#x27;s atmosphere\"><figcaption>Huygens treedt de atmosfeer van Titan binnen<\/figcaption><\/figure>\n<p>Terwijl de temperatuur van het hitteschild oploopt tot 8.000 \u00b0C, wordt de buitenkant van de sonde roodgloeiend.
