Eberswalde crater on Mars formed more than 3.7 billion years ago. The rim of the crater is intact only on the right-hand side. The rest has been buried by ejecta [BOX 1] from the larger, more recent Holden impact crater.
Eberswalde crater contains a rare case of a martian delta [BOX 3]. Channels [BOX 2] which fed the lake in the crater are very well preserved. The delta deposits and channels together provide a clear indication of liquid surface water during the early history of Mars.
The image was acquired by Mars Express around 25°S / 326°E during orbit 7208 on 15 August 2009. The images have a ground resolution of about 22 m per pixel.
