摘要
| 描述 |
English: Hyperboreae_Undae Today's VIS image shows part of Hyperboreae Undae, a dune field located between the north polar cap and Escorial Crater. This image was taken during northern spring and the dunes still have significant surface frost. The dunes "darken" with time as the frost sublimates from solar heating and the dark sands are revealed. |
