Ganna (Anya) Portyankina has a Master degree in Physics and Astronomy and a PhD in Astrophysics from Göttingen University, Germany. Her main expertise is remote sensing of planetary surfaces and atmospheres. She researches behaviour of different ices and their interactions with atmospheres and surfaces to reveal how they are able to shape planetary surfaces into terrains we observe.
The Mars I study is really active; the surface constantly changes. We have collected a lot of image data about changing seasonal features near the south pole. There is so much that we can't analyze all of it on our own. We need your help, through a new Zooniverse project named PlanetFour.
