Det finns inga garage i rymden. N\u00e4r en rymdfarkost har l\u00e4mnat jorden hoppas alla att alla system ombord ska fungera som de ska. Under de f\u00f6rsta varven \u00e4r det ESOC:s, ESA:s europeiska rymdoperationscentrum, uppgift att kontrollera att rymdfarkosten befinner sig i r\u00e4tt bana och att dess huvudsystem \u2013 kommunikation, str\u00f6mf\u00f6rs\u00f6rjning osv. \u2013 fungerar.<\/p>\n<\/div>\n

Om rymdfarkosten drivs med solenergi \u00e4r en av de f\u00f6rsta uppgifterna att f\u00e4lla ut \u2018vingarna\u2019 s\u00e5 att de kan ta upp solljus.<\/p>\n

N\u00e4r rymdfarkosten har genomg\u00e5tt en lyckad kontroll b\u00f6rjar ingenj\u00f6rerna att sl\u00e5 p\u00e5 instrumenten, ett efter ett. Detta kallas \u2018idrifttagning\u2019.<\/p>\n

De f\u00f6rsta bilderna eller m\u00e4tningarna visar om instrumenten fungerar som f\u00f6rv\u00e4ntat. Om s\u00e5 inte \u00e4r fallet justeras de tills resultaten f\u00f6rb\u00e4ttras. ESOC kontrollerar ocks\u00e5 att instrumenten inte st\u00f6r andra instrument i n\u00e4rheten.<\/p>\n

Ett av de mest komplicerade drifts\u00e4ttningsprogrammen g\u00e4llde ESA:s Cluster-satelliter. De fyra Cluster-satelliterna, som sk\u00f6ts upp sommaren 2000, \u00e4r utrustade med sammanlagt 44 instrument.<\/p>\n

Grupper av forskare och ingenj\u00f6rer var tvungna att f\u00f6lja en detaljerad plan f\u00f6r att kontrollera och \u00f6vervaka varje satellit och dess instrument. Det dr\u00f6jde mer \u00e4n tre m\u00e5nader innan rymdfarkosterna var redo att p\u00e5b\u00f6rja sitt uppdrag att studera sambandet mellan solen och jorden.<\/p>","protected":false},"excerpt":{"rendered":"
