ESA:s senaste b\u00e4rraket, Vega, har genomf\u00f6rt en lyckad andra flygning fr\u00e5n Europas rymdbas i Kourou i Franska Guyana. Vega lyste upp m\u00f6rkret n\u00e4r den lyfte kl. 02:06 GMT den 7 maj p\u00e5 ett komplicerat uppdrag f\u00f6r att placera tre satelliter \u2013 d\u00e4ribland ESA:s Proba-V \u2013 i l\u00e5g omloppsbana runt jorden.<\/p>\n<\/div>\n

Raketens alla tre steg med fast br\u00e4nsle fungerade felfritt. Proba-V sl\u00e4pptes ut i en cirkul\u00e4r bana p\u00e5 820 km h\u00f6jd, \u00f6ver Australiens v\u00e4stkust, cirka 55 minuter efter uppskjutningen. Kontrollen \u00f6ver satelliten \u00f6vertogs av ESA:s centrum i Redu, Belgien, som kommer att \u00f6vervaka en fullst\u00e4ndig h\u00e4lsokontroll och testrutin innan den tas i normal drift.<\/p>\n

Proba-V v\u00e4gde cirka 140 kg vid uppskjutningen. Det \u00e4r den tredje i ESA:s serie av Proba-satelliter, som skickas upp f\u00f6r att testa ny rymdteknik. Proba-V:s huvuduppgift \u00e4r att kartl\u00e4gga den globala vegetationen.<\/p>\n

Vegetationsdata ger forskarna information om olika typer av markt\u00e4cke och v\u00e4xtarter, inklusive odlingsgr\u00f6dor. P\u00e5 detta s\u00e4tt kan man f\u00e5 en bild av deras h\u00e4lsotillst\u00e5nd, och man kan uppt\u00e4cka vattendrag och br\u00e4nnm\u00e4rken i vegetationen.<\/p>\n

Dessa data kommer att anv\u00e4ndas f\u00f6r att bed\u00f6ma klimatets inverkan p\u00e5 vegetationen, f\u00f6rvalta ytvattensresurserna, \u00f6vervaka jordbruket och bed\u00f6ma livsmedelss\u00e4kerheten \u00f6ver hela v\u00e4rlden, s\u00e4rskilt i de minst utvecklade omr\u00e5dena. Trots att den bara \u00e4r n\u00e5got st\u00f6rre \u00e4n en tv\u00e4ttmaskin kommer den att ge skarpa bilder av jordens v\u00e4xtliv varannan dag.<\/p>","protected":false},"excerpt":{"rendered":"
