Crater Hale in Argyre basin
European Space Agency
Mars Express
24 November 2004

These images, taken by the High Resolution Stereo Camera (HRSC) on board
ESA's Mars Express spacecraft, show Crater Hale in the Argyre basin of
the southern hemisphere of Mars.
 
 
Map showing Crater Hale in context

The images show an area close to the northern rim of the Argyre basin,
located at latitude 36? South and longitude 324? East.

The image was taken with a ground resolution of about 40 metres per
pixel during Mars Express orbit 533 in June 2004.

Slight periodic colour and brightness variations in parts of the image
indicate atmospheric waves in clouds.

Crater Hale, with its terraced walls, central peak and a part of the
inner ring is visible in the upper (eastern) part of the image. The
region has been eroded heavily by deposits caused by this impact, and
subsequent processes.

On the southern rim of Hale, parts of the crater wall have moved
downslope towards the crater's centre (see black and white detailed
image left).

At the bottom (western) part of the picture, as seen below in the other
detailed image with high resolution, the surface shows a network of
fluvial channels which may have been caused by running water.

Image resolution has been decreased for use on the internet. The colour
images were processed using the HRSC nadir (vertical view) and three
colour channels.

The perspective views were calculated from the digital terrain model
derived from the stereo channels.

 

3D image of Crater Hale
 
The 3D anaglyph image was created from the nadir channel and one of the
stereo channels. Stereoscopic glasses are needed to view the 3D image.
