ROLIS descent image in 3D
The image shows comet 67P/CG acquired by the ROLIS instrument on the Philae lander during descent on Nov 12, 2014.
This image combines two ROLIS images, acquired about an hour before the first touchdown at 15:34 GMT/16:34 CET (time onboard the spacecraft), which was confirmed on Earth at 16:03 GMT/17:03 CET. The images are separated by two minutes and the resolution is three metres per pixel.
To appreciate the 3D effect, the image must be viewed with red-blue/green glasses.
The ROLIS instrument is a down-looking imager that acquires images during the descent and doubles as a multispectral close-up camera after the landing. The aim of the ROLIS experiment is to study the texture and microstructure of the comet's surface. ROLIS (ROsetta Lander Imaging System) is a descent and close-up camera on the Philae Lander. It has been developed by the DLR Institute of Planetary Research, Berlin.

Really interesting stuff, tracking for sure.

the following link http://edition.cnn.com/2014/11/24/world/philae-lander-revival/index.html?hpt=wo_c2 has some other information
but also includes the potential sequence of revival of philae:

O'Rourke believes that if the lander comes back online there's a high chance it will survive until the comet's closest approach to the sun in August next year.
So how does Philae come back from the dead?

O'Rourke explained the sequence:

- If enough sunlight falls on the solar panel, Philae will reboot
- It then needs more energy to warm the batteries
- Once warmed, the batteries will start recharging
- When it has enough power Philae will try to contact the orbiting Rosetta -- for two minutes every 30 minutes.
- If it fails to make contact, Philae will power down the transmitter and try again 30 minutes later

The power it needs is tiny -- roughly equivalent to the output of two or three domestic AA batteries -- but it will be enough to restart the lander mission.

Comet on 20 November – NAVCAM



This mosaic comprises four individual NAVCAM images taken from 30.8 km from the centre of Comet 67P/Churyumov-Gerasimenko on 20 November 2014. The image resolution is 2.6 m/pixel and thus each original 1024 x 1024 pixel frame measured 2.7 km across. The mosaic has been slightly rescaled, rotated, and cropped, and measures roughly 4.2 x 5.0 km.

and here is for comparison:

Exceptionally, an increased exposure and contrast version of the mosaic is also provided to give an even better view of the outflowing material.

another picture in two versions:



This four-image montage comprises images taken on 26 November from a distance of 30.1 km from the centre of 67P/Churyumov-Gerasimenko. The image resolution is 2.4 m/pixel so each original 1024 x 1024 pixel frame measures about 2.5 km across.
A quick look at the lower-left and lower-right images (first and last in the sequence) will rapidly reveal that the rotation of the comet has been substantial in the twenty minutes that passed between the two images being taken, meaning that mosaicking tools are likely to introduce some serious artefacts. For example, look at how the shadows have changed around the distinctive U-shaped feature close to the boundary between the two lower frames.
The comet continues to show outflows of gas and dust, which are even more evident in the higher contrast version of the montage provided below. This higher contrast version also brings out the details of some of the shadowed regions, such as the steep cliffs that rise up to the large depression on the smaller of the comet’s two lobes.
The higher contrast montage also highlights some scattering artefacts (e.g. the rounded feature in the top left frame) and vignetting (centre of the montage).

another black and white photo from navcam:
