Today will be a historic day: the first docking of a new kind of spacecraft :cool:

After two successful demonstration days on December 29 and 31, the first ATV can finally dock to the aft end of the Russian module Zvezda.
If all goes well again Jules will dock at 14:41 GMT. (EDT=GMT-4, CEDT=GMT+2)

NASA TV will cover this event from 12:00 - 15:00 GMT and show the Post-Docking Briefing at 16:30 GMT.

ArianespaceTV will also show the docking in English and French starting at 14:00 GMT , we don't know if it will be anything different from NASATV coverage so we will have to check:

ESA will post the latest updates at its ATV blog: http://webservices.esa.int/blog/blog/1/

Timing and description of the different steps during approach (so called "station keeping points") can be found here at http://www.esa.int/SPECIALS/Operations/SEMSFJM5NDF_0.html

Well, here's the timeline for todays docking:


*S-1/2(39 km behind and 5 km below)  12:33 CEST - ATV in waiting mode for final go ahead
 
S0(30 km behind and 5 km below) Pre-homing
 
S1 (15.5 km behind and 5 km below) 13:19 CEST - Homing starts
 
S2(3.5 km behind and 100 m above)  14:05 CEST - Station keeping point. External lights are activated. Russian Kurs radar-based system is activated and the ISS crew can begin using this data. Closing begins using relative GPS.
 
500 m  Video system of Zvezda turned on for ISS crew to view ATV on the Simvol screen.
 
S3(249 m behind)  15:17 CEST - Station keeping point. The Videometer and Telegoniometer (laser-pulsed instruments that calculate the distance and orientation to the ISS) are activated. Videometer is used as the prime sensor for GNC navigation. Go for Final Approach 1.
Speed of ATV slows down from about 40 cm per second to 7 cm per second
 
S4(19 m behind) 16:15 CEST - Station keeping point. Close range videometer navigation is used. Pointing manoeuvre towards the Docking Port axis. Go for Final Approach 2.
 
S41(11 m behind) 16:33 CEST - Station keeping point. Go to continue the Final Approach 2.
 
 ATV docks to Zvezda

From ATV blog:
http://webservices.esa.int/blog/post/1/302

13:18:50 CEST - Arrival at S1
Jules Verne just arrived at S1 - that is a point 15.5 km behind ISS and 5 km below. AND... we have just got our first glimpse of Jules Verne here in the control centre. Right now still a dot in the distance.

Docking could be delayed slightly (~15min) due to lighting and telemetry issues with Russian ground stations

From the ATV blog:
http://webservices.esa.int/blog/post/1/310

14:04 CEST - Arrived at S2
Jules Verne ATV has arrived at S2 - now just 3.5 km away from ISS. This is a so-called station keeping point. Jules Verne will remain here for just over 30 minutes. Whilst in this position the spacecraft's external lights will be activated. The Russian Kurs radar-based system will also be activated - the crew will use data from the Kurs to check the relative GPS data they see on the Simvol.

ESA update:

On the ATV-CC voice loop we just heard "HOLD and RETREAT commands are correct" ... Today these are test commands sent to Jules Verne to make sure that they are being received properly. The news is - they were received ok.

It's moving:
A few minutes ago Jules Verne ATV received the go for next phase - CLOSING. During CLOSING, ATV is transferred by 4 burns from the S2 station keeping point to S3 (249 m away from ISS). The first CLOSING boost is underway.
-- Maria

ATV scheduled to arrive at S3 at 15:15 CEST
