| | | | | | | Rare martian lake delta spotted by Mars Express
2 September 2011
| Holden crater is 140 km across, filling the left side of the image, while to the right is the remaining part of Eberswalde crater, with a diameter of about 65 km. They are located in the southern highlands of Mars. North is to the right of the image.
The image was acquired by Mars Express at approximately 25°S / 326°E during orbit 7208 on 15 August 2009. The images have a ground resolution of about 22 m per pixel.

| | | | | Eberswalde crater contains a rare case of a martian delta. Channels 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.

| | | | | 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 on Mars formed more than 3.7 billion years ago. The rim of the crater is intact only in the north-eastern part. The rest has been buried by ejecta from the larger, more recent Holden impact crater nearby. 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.

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. The image was derived from the nadir channel, which provides the highest detail of all the channels. North is to the right.

It combines data from HRSC’s nadir channel and one stereo channel to produce this 3D image. Stereoscopic glasses are required to see the 3D effect.
