ATV hatch closing complete
This in from Mike Steinkopf at ATV-CC on the completion of today's hatch-closing activities.
The depressurization and the leak check were successfully performed this evening and further operations will be performed during the week-end in order to be ready for ATV-4 undocking, Monday, 28 Oct.
ATV-4 ready for hatch closure – set for 16:10 CEST
This information was provided by ESA's Mike Steinkopf, Mission Director on console at ATV-CC for today's hatch closing.
ATV-4 is ready for today's hatch closure, which is planned at 16:10 CEST. Before hatch closure, the crew will remove various equipment – which will be used for the next ATV – such as the air exchange duct, fire extinguisher, gas masks and the handrails. Also, items such as the smoke detectors and the lamp housing assembly will be removed to be used as spares for other modules in ISS. The ATV and ISS hatch closure operation will start at about 15:25 CEST and finish at 18:10 CEST.

This week, the crew performed the last trash-loading activities and the last liquid-waste transfer. After that, crew took about 50 photos of the trash-loading configuration inside ATV to be reviewed by ESA cargo specialists.
This is an important task to verify that all trash has been loaded according to the return cargo map and that all items are properly and safely installed within the racks and on the Adapter plates.
The correct loading of trash is necessary to ensure that ATV is within the MCI (Mass Centre of Inertia) requirements for undocking and re-entry. In case of any deviations in the trash loading configuration (compared to the return cargo map) occurs, the crew would need to perform some CoG (Centre of Gravity) corrections before hatch closure following ESA cargo specialists inputs relocating trash items.
After photo review and verification by our specialists, no CoG correction was necessary.
Mission report 24 October
The IMMT – the ISS Mission Management Team (IMMT), the coordinating body comprising all ISS partner agencies (ESA, NASA, JAXA, CSA, Roscosmos/RSC-E) – has given the 'go' for ATV-4 undocking, set for Monday 28 October. This marks the start of a series of steps that will prep the ESA cargo vessel for departure followed by a controlled destructive re-entry on 2 November. Egress and final hatch closure are set for Friday, 25 October, at 16:00 CEST.

Final station reboost complete
Update from ESA's Thomas Beck at ATV-CC on today's reboost, the last planned reboost of the ATV-4 mission.
At 13:03 CEST, ATV-4 used two of its main engines, OCS1 and OCS3, to lift the ISS into a higher orbit. After a burn of 256.6 secs, the velocity of the orbital complex was changed by 0.62 m/sec. The manoeuvre burned 86.0kg of propellant.
This was the last scheduled reboost of ATV-4, which is set to undock from the ISS on Monday, 28 October 2013.
ATV-4 set to lift the Station tomorrow
Details on tomorrow's planned reboost for the ISS – the final one in the ATV-4 mission – from ESA's Thomas Beck at ATV-CC.
The reboost on Thursday [24.10] is planned to generate a modest delta-V (change in speed) of about 0.6 m/sec and to use approximately 85 kg of fuel.
The corresponding small increase in ISS altitude should be on the order of a bit less than 2 kilometres. The back-up date for this reboost is Saturday, 26 October.
I will provide more up-to-date figures after reboost termination.
ATV-4 communications equipment ready for undocking
The Proximity Communications Equipment (PCE) was unpacked and set up in the Russian Service Module (SM) on 17 October by Expedition 37 Flight Engineer Oleg Kotov. The PCE transponder is linked to an external antenna on the SM and provides direct communication between ATV and the ISS. It's usually kept stowed as it's not needed when ATV is attached.
NASA TV to cover ATV-4 undocking
Now in the NASA TV schedule: Coverage of the 28 October undocking of ATV Albert Einstein, Automated Transfer Vehicle 4, from the ISS. Undocking scheduled at 9:59 CET. Programme runs 9:45-11:00 CET.
Preps for Cygnus departure marks start of high-traffic season on ISS
Meanwhile, Flight Engineer Oleg Kotov installed and connected a control panel to monitor the departure of the European Space Agency’s Automated Transfer Vehicle-4 (ATV-4), which is set to undock from the aft port of the Zvezda service module on Oct. 28 after more than four months at the station. Like Cygnus, the ATV-4 will be de-orbited for a fiery demise over the Pacific Ocean.

The departure of ATV-4 will clear the way for Nyberg, Parmitano and Commander Fyodor Yurchikhin to relocate their Soyuz 35 from its docking port on the Rassvet module to the newly vacated Zvezda port on Nov. 1.

Especially the Russian modules stand out well in this image -- but you can see how Europe's fourth Automated Transfer Vehicle, ATV Albert Einstein, causes a thick extension of the aft end of the station. It looks bigger, in any case more obvious then the Zvezda module, one of the main modules of the Russian side of the ISS. Credit: R. Vandebergh

Meanwhile, back in space…
... ATV-4 continues its mission! And we are delighted to share with you some excellent images of Albert Einstein doing just that! These were acquired by Yoshiaki Sakai, from Japan, and show the ISS & ATV in orbit and transiting the Sun. Details on location, equipment used, to follow.
