Five short days to go.
That final maneuver will be touching down on comet 67P/C-G.
Spent my morning with the video and a nice cup of tea, time well spent.
Simply an incredible mission.
Philae has been found! Click the image above to see an annotated version.
The find is very timely, on 30 September 2016, Rosetta will make the final rendezvous with the comet.
Close-up of the Philae lander, imaged by Rosetta’s OSIRIS narrow-angle camera on 2 September 2016 from a distance of 2.7 km. The image scale is about 5 cm/pixel. Philae’s 1 m-wide body and two of its three legs can be seen extended from the body. The images also provide proof of Philae’s orientation.
The image is a zoom from a wider-scene, and has been interpolated.

ESA gives us this visualization of Rosetta’s journey. The video gives us a pretty good sense of the journey and how exacting the planning was and what it will be in the future, although the final bits of the journey were not completely finalized until after this visualization was made.

I am always am amazed how ESA can make the very difficult look easy.
On 30 September ESA’s Rosetta spacecraft will end up on the surface of Comet 67P/Churyumov–Gerasimenko after an unbelievably successful mission.
See the time line from ESA.
The Philae lander on Comet 67P/Churyumov–Gerasimenko will likely be spending eternity in silence. “The chances for Philae to contact our team at our lander control centre are unfortunately getting close to zero,” says Stephan Ulamec, Philae project manager at the German Aerospace Center, DLR. “We are not sending commands any more and it would be very surprising if we were to receive a signal again.”
If things go as planned, Rosetta may be joining Philae when later this year when the spacecraft’s propellant runs low a landing attempt is made. This (hopefully) won’t be a large impacting event, rather a gentle touchdown and Rosetta will continue to collect and transmit data until the last. Might it even work from the surface for a short time? Probably not, but who knows.
Be sure to check out the “comet viewer tool” linked below.
This beautiful landscape feels within arm’s reach in this stunning view across the Imhotep region on Comet 67P/Churyumov–Gerasimenko.
The view was captured by Rosetta’s OSIRIS narrow-angle camera on 17 January 2016, from a distance of 86.8 km. Measuring 3.2 km across, it captures one of the most geologically diverse areas of the comet.
Imhotep is perhaps most easily identified by the broad smooth area that occupies the centre-right portion of this view. This smooth dusty terrain, which covers about 0.8 sq km, is etched with curvilinear features stretching hundreds of metres and which have been found to change in appearance over time.
Many large boulders are also seen scattered within the smooth terrain, including the boulder Cheops in the foreground. Smaller but more numerous boulders are associated with exposed cliff faces and are most likely the product of erosion. In some debris falls, detailed analysis has revealed the presence of water ice.
Particularly eye-catching is the distinctive layered and fractured material to the left of centre in the background. Similar patterns are also seen in the exposed cliff-like faces towards the right of the scene too, where Imhotep transitions into the Khepry region.
Just in front of the prominent left-hand stack of layers a number of small round features can be found. They have a well-defined rim with a smooth interior and appear slightly raised from the surrounding material. One explanation for their appearance is that they are ancient sites of active regions covered by dust and are now being revealed by varying erosion of the overlying layers.
Further in the foreground again and a relatively smooth ‘pathway’ appears to lead towards a more consolidated summit. To the left of this path is the Ash region, while the sheer apex at the top left of the view marks the boundary with Apis.
Use the comet viewer tool to aid navigation around the comet’s regions.

A great 3D image from the Rosetta spacecraft.
A 3D anaglyph view of Comet 67P/Churyumov–Gerasimenko based on two images from Rosetta’s OSIRIS camera on 12 August 2015, capturing a spectacular jet. The two images are separated by 2 minutes 28 seconds, which corresponds to a stereo angle of 1.2º. The image scale is 3.9 m per pixel. In this orientation the Babi and Aker regions are visible on the large lobe to the left, while Ma’at and the circular Hatmehit depression are seen on the small lobe to the right. Diffuse dust emission and other jets are visible all around the nucleus.
The image is best enjoyed with red–blue/green 3D anaglyph glasses.

Rosetta has been returning some stunning images of Comet 67P/Churyumov-Gerasimenko that ESA is putting up on the Rosetta Blog.
This one shows 67P/G-C from a distance of 415 km / 258 miles show nice outgassing. We are looking at the southern hemisphere some of which has been in darkness for five and a half years, just becoming visible in May.
