ESAn uusin kantoraketti Vega on suorittanut onnistuneesti toisen lentonsa Euroopan avaruuskeskuksesta Kourousta, Ranskan Guayanasta. Vega valaisi pimeyden noustessaan ilmaan 7. toukokuuta kello 02.06 GMT monimutkaisella teht\u00e4v\u00e4ll\u00e4, jonka tarkoituksena oli vied\u00e4 kolme satelliittia \u2013 mukaan lukien ESA:n Proba-V \u2013 matalalle maankiertoradalle.<\/p>\n<\/div>\n

Raketin kaikki kolme kiinte\u00e4polttoaineista vaihetta toimivat moitteettomasti. Proba-V vapautettiin 820 km:n korkeudella sijaitsevalle py\u00f6re\u00e4lle kiertoradalle Australian l\u00e4nsirannikon yl\u00e4puolelle noin 55 minuuttia laukaisun j\u00e4lkeen. Satelliitin ohjaus siirtyi ESA:n Redun keskukselle Belgiassa, joka valvoo satelliitin t\u00e4ydellist\u00e4 toimintatarkastusta ja testausrutiinia ennen sen normaalin toiminnan aloittamista.<\/p>\n

Proba-V painoi laukaisun yhteydess\u00e4 noin 140 kg. Se on kolmas ESA:n Proba-avaruusalussarjassa, jonka avulla testataan uusia avaruusteknologioita. Proba-V:n p\u00e4\u00e4teht\u00e4v\u00e4n\u00e4 on kartoittaa maailman kasvillisuutta.<\/p>\n

Kasvillisuustiedot antavat tutkijoille tietoa erilaisista maank\u00e4ytt\u00f6tyypeist\u00e4 ja kasvilajeista, mukaan lukien viljelykasvit. N\u00e4in voidaan selvitt\u00e4\u00e4 niiden kunto sek\u00e4 havaita vesist\u00f6j\u00e4 ja kasvillisuuden paloj\u00e4lki\u00e4.<\/p>\n

N\u00e4it\u00e4 tietoja k\u00e4ytet\u00e4\u00e4n arvioimaan ilmaston vaikutusta kasvillisuuteen, hallinnoimaan pintavesivaroja, seuraamaan maataloutta sek\u00e4 arvioimaan elintarviketurvaa ymp\u00e4ri maapalloa, erityisesti v\u00e4hiten kehittyneill\u00e4 alueilla. Vaikka laite on vain hieman pesukonetta suurempi, se tarjoaa tarkkoja kuvia maapallon kasvillisuudesta kahden p\u00e4iv\u00e4n v\u00e4lein.<\/p>","protected":false},"excerpt":{"rendered":"
