GOOD LUCK! I can hardly believe the day has finally come – it’s been a long time!
Update: Landing confirmed. Harpoons did not fire, investigation in progress. The one way radio travel time is a bit over 28 minutes – each way.
ESA is reporting all is well with Philae is in good shape despite the harpoons.
If you see no video above it is because ESA isn’t broadcasting at the time.
Check out the Rosetta Blog and for last second updates.

The big day is almost here. What will happen once Philae lands on Comet 67P/Churyumov–Gerasimenko?
This from ESA:
A timeline of the science operations that Rosetta’s lander Philae will perform during the first 2.5 days on the surface of Comet 67P/Churyumov–Gerasimenko.
It does not include the experiments conducted during the seven-hour descent or immediately upon touchdown and in the 40 minutes after as the separation, descent and landing operations and experiments conclude (see this graphic for a summary of those activities).

An image on 04 November shows some activity in the way of the jets emanating from the central region of comet 67P/Churyumov-Gerasimenko.
For the past couple of weeks I’ve developed quite an interest in what the cometary “soil” is like and how it got to be the way it is. Happily we could get more clues just watching the Philae lander land on Wednesday. If the composition is very fine we could see quite a cloud kicked up relative to how much is at the landing site of course.

Just three days away.
This is Friday’s press conference with Rosetta mission experts hosted by Emily Baldwin, ESA space science editor / Rosetta Blog
The video is in distinct segments of about 15 minutes and questions at the end.
Introduction and mission plans fellowed by Science at 15 minutes, Landing at 30 minutes and Summary at 45 followed by questions.
Wow, what a great view of a comet you can get from just 30 km (18.6 miles).

This image of comet 67P/Churyumov-Gerasimenko was obtained on October 30, 2014 by the OSIRIS scientific imaging system on the Rosetta spacecraft. The right half is obscured by darkness. The image was taken from a distance of approximately 18.6 miles (30 kilometers).

Landing “Site J” on Comet 67P/Churyumov-Gerasimenko has a new name and that name is Agilkia.
Agilkia is an island on the Nile River in the south of Egypt. A complex of Ancient Egyptian buildings, including the famous Temple of Isis, was moved to Agilkia from the island of Philae when the latter was flooded during the building of the Aswan dams in the 20th century.
Pretty good name I think and so do others, the name was proposed by 150 of the participants of public competition held by ESA and the German, French and Italian space agencies.
The image shows Agilkia in one of those four-part mosiacs ESA has been releasing. Very nice resolution panels so do check it out. This is one of the last looks as Rosetta left the 10 km orbit to get ready to deploy Philae on 12 November.
About the video from ESA (YouTube)
Ambition is a collaboration between Platige Image and ESA. Directed by Tomek Bagiński and starring Aiden Gillen and Aisling Franciosi, Ambition was shot on location in Iceland, and screened on 24 October 2014 during the British Film Institute’s celebration of Sci-Fi: Days of Fear and Wonder, at the Southbank, London.

Here is one panel of four images from the Rosetta spacecraft on 18 October when the spacecraft was only 7.8 km from the surface.
The image scale is about 92 cm per pixel according to the caption
The images here were taken about 20 minutes apart and the rotation is apparent, so Photoshop route of putting them together isn’t working out so good. Trying to accomplish the task of putting the four frames together is made more difficult because I am doing it on a laptop. I have a new plan: I am going to print each panel out and see if I can stick them together just for fun, if it works out I will print the frames out on photo paper and put everything on the wall.
You can see all four panels at the Cometwatch Blog you can see if you can put them together too.
I picked this particular image for a couple of reasons: check out the boulders. Seems like they should be rolling down the hill, that’s what having little gravity does for you.
The really interesting thing is towards the center of the image, are those dunes? If they are how did they form?
A great ESA animation depicting Rosetta’s orbits and separation of the Philae lander.
On 12 November, Rosetta will move to 22.5 km from the comet and release Philae.
The lander will take about seven hours to get to the surface. In the meantime Rosetta will be maneuvered back to about 50 km from the comet so the lander stays visible. The lander communicates via Rosetta so the visibility is important. Eventually Rosetta’s orbit will be moved back to 20 km.
The actual rotation rate of the comet is 12.5 hours so yes the animation is sped up considerably – it does help the animation.

Very nice! This image was taken with the CIVA camera on the Philae lander which is of course still attached to ESA’s Rosetta spacecraft. Just wait until Philae sends pictures from the comet surface.
Comet 67P/Churyumov–Gerasimenko is in the background about 16km away.
