This is a link to one of the MODIS Rapidfire Terra satellite images from June 28, 2009, showing that a large section of the floating tongue of the Petermann Glacier has broken off and then rotated about 180°. It appears that this section usually goes during the summer. "Upstream" on the tongue, cracks have appeared (not visible in this image) some months ago.
