MAGELLAN GIF IMAGE XCUT
This is a Magellan radar image of parts of the Lakshmi
region of Venus. The mosaic is part of revolutions 390 and 391
acquired on September 17, 1990. The image is located at 30
degrees north latitude, 333.3 degrees east longitude, and is
about 37 kilometers (23 miles) wide and 80 kilometers (48 miles)
long. On the basis of Pioneer Venus and Arecibo data, it is
known that the region shown is located on the low rise separating
Sedna Planitia and Guinevere Planitia, and just to the west of
Eistla Regio. The image shows two sets of parallel lineations
which intersect almost at right angles. The fainter lineations
are spaced at a regular interval of about one kilometer and
extend beyond the boundaries of the image. The width of these
faint lineations is at the limit of resolution of the best
Magellan images. The brighter, more dominant lineations are less
regular and appear in places to begin and end where they
intersect the fainter lineations. It is not clear whether the
two sets of lineations represent faults or fractures, but in
other areas outside the image, the bright lineations are
associated with pit-craters and other volcanic features. This
type of terrain has not been seen previously, either on Venus or
the other planets. Resolution of the Magellan data is about 120
meters (400 feet).
