A NASA marsjárója, a Perseverance kamerája előtt három porördög is megjelent nemrég. Az ezekről készített képeket animációba fűzte össze a szervezet egyik mérnöke.
Jó ideje tudni lehet már, hogy a Mars felszínén is kialakulhatnak az úgynevezett porördögök. Ezek a földihez hasonlóan örvénylő levegőoszlopok, amik kimondottan tiszta időben jönnek létre, amikor a hirtelen felszálló meleg levegő miatt a bolygófelszínen lévő porréteg megmozdul.
Korábban több felvétel is készült már ezekről, lefotózni őket azonban mégsem olyan egyszerű, mert bár gyakoriak, ehhez jókor, jó helyen kell lenni. A NASA marsjárójának, a Perseverance-nek ebben a tekintetben igen nagy szerencséje volt, sikerült ugyanis lencsevégre kapnia a jelenséget – és nem is egyet, hanem rögtön hármat.
A Perseverance kamerája több képet is készített még 2022. március 7-én, ezeket pedig a NASA mérnöke, Kevin M. Gill szerkesztette animációvá.
Mivel a marsi légkör 100-szor ritkább a földinél, ezek a porördögök túl nagy kárt nem tudnak okozni, ahhoz azonban elegendőek, hogy hosszú idő alatt alakítsák a marsi talajt.
