Det er utroligt at t\u00e6nke p\u00e5, at selvom den klare bl\u00e5 himmel ser helt tom ud p\u00e5 en solskinsdag, s\u00e5 er der faktisk tusindvis af store metallsatellitter, der kredser om vores planet!<\/p>\n<\/div>\n

Disse usynlige arbejdere udf\u00f8rer alle mulige vigtige opgaver, lige fra at g\u00f8re det muligt for os at holde kontakten med vores familier og venner til at hj\u00e6lpe os med at forst\u00e5 vores planet bedre.<\/p>\n

En af satellitfl\u00e5derne hedder \u00bbSentinels\u00ab. En \u00bbsentinel\u00ab er en vagt eller soldat, hvis opgave er at holde vagt og s\u00f8rge for vores sikkerhed. Og netop det er det, Sentinel-satellitterne skal g\u00f8re!<\/p>\n

I f\u00e6llesskab vil de udforske vores hjemplanet, fra havene til himlen. De data, de sender tilbage, vil hj\u00e6lpe os med at tackle alle former for milj\u00f8problemer, b\u00e5de naturlige og menneskeskabte.<\/p>\n

Farvesyn til Sentinel-2<\/figcaption><\/figure>\n

Sentinel-familien vokser stadig. Den f\u00f8rste satellit blev opsendt sidste \u00e5r, og senere p\u00e5 m\u00e5neden f\u00e5r den et nyt medlem, Sentinel-2A. Denne satellit vil udg\u00f8re den ene af et par, der kaldes Sentinel-2. Den f\u00f8rste vil blive sendt i kredsl\u00f8b den 23. juni, og den anden satellit, Sentinel-2B, vil slutte sig til den n\u00e6ste \u00e5r.<\/p>\n

Sentinel-2 vil v\u00e6re udstyret med et meget kraftfuldt kamera, der vil give fl\u00e5den farvesyn. De to satellitter vil arbejde sammen om at unders\u00f8ge plantelivet og vandet p\u00e5 Jordens overflade. De indsamlede data vil hj\u00e6lpe os med at forbedre landbruget, s\u00e5 vi kan dyrke mere mad, og vise os, hvilket vand der er sikkert at drikke.<\/p>\n

Sentinel-2 vil ogs\u00e5 overv\u00e5ge vores skove, der bliver mindre og mindre, og vores byer, der vokser. Satellitterne vil hj\u00e6lpe os med at finde ud af, hvor der er risiko for sygdomsudbrud, eller fort\u00e6lle folk, hvor de skal s\u00f8ge hen i n\u00f8dsituationer. Det vil hj\u00e6lpe os med at beskytte vores dyrebare verdens landomr\u00e5der og befolkning.<\/p>\n

Sjovt faktum:<\/b> Sentinel-2A vil kredse dobbelt s\u00e5 h\u00f8jt over Jorden som Den Internationale Rumstation!<\/p>","protected":false},"excerpt":{"rendered":"
