good find Space Pete and welcome back, hope you got all rested up.

Heh, thanks Prober.

It sure was nice to see the Sun for a change, instead of the usual British cloud and rain. 8)

But I'm back now and ready to assume my ISS coverage duties once again. :)

That looks awesome!
Human spaceflight is basically just LARPing now.

Discussion occurred this morning:

(I tweaked the recorder settings just now as it sounds like they turned the volume down just a bit, so some of the audio drops out in this clip but you get the point)

At the bottom of the article, it states that there are 6 crew members on board. I think this may be a rehash of an old article.

The link now says that the DAM has been cancelled.

Not sure which thread to post this in, since this is the current Exp, I'll try here first.

I noticed in Space Pete's informative article on ATV-3 de-orbit that pretty much half of the upmass of ATV-3 was reboost prop (3400kg).  I was under the impression that once the "big reboost" to 400+ km orbit occured, there would be a significant decrease in drag/less need for reboost.  The 3400kg for reboosting sounds like a lot to me.  Is there in fact more drag/requirement for reboost at 400+ km orbit than anticipated?

Is there in fact more drag/requirement for reboost at 400+ km orbit than anticipated?

Yup, exactly right.

From my March 6 article "Europe’s ATV-3 spacecraft set to deliver large cargo load to ISS"
http://www.nasaspaceflight.com/2012/03/europes-atv-3-spacecraft-deliver-large-cargo-load-iss/

Quote
During the ATV-2 mission in 2011, four “big boosts” of the ISS were performed by the ATV-2 SM to raise the altitude of the ISS by 30 km, to around 400 km, in order to decrease the requirements for reboosts in the post-Shuttle era due to lesser atmospheric drag at higher altitudes.

Due to this decreased requirement for propellants, and thus increased capacity for dry cargo, numerous modifications were planned for the ATV ICCs from ATV-3 onwards, including the addition of Enhanced Integrated Stowage Platforms (EISPs), an Aft Carrier Plate (ACP) and Aft Cargo Frames (ACFs) to stow cargo on the aft endcone of the ICC, and stowing cargo in the rack standoff support structures. However, as explained by an ESA ATV engineer in a Q&A with NASASpaceflight.com (available in full on L2), such modifications are now no longer planned.

“These modifications were based on very low propellant estimates from the NASA Viper team (the folks who manage the ISS requirements for fluid and dry cargo). The desire for these modifications came from an earlier (ca. 2009) high-level estimate of ISS needs over the next five years. Based on this information, ESA’s ATV team were told that the ISS propulsive support propellant would be the minimum possible amount and that the water and refuelling propellant would have a total combined mass of no more than 860 kg.”

“However, recent updates to that estimate foresee a much higher propellant support need and a minimum of 860 kg of refuelling propellant as well as a possibility for water. All of this implies that there will be, in future ATVs, a higher ratio of dry cargo vs. liquid.”

Thanks for the quick response!  And thanks for the excellent work/coverage of our manned space program...

BBC Breakfast are reporting another DAM is to take place. Cannot find any other reports of this. Are they barking up the wrong tree?

First CubeSats release is finished.
I posted here.

First CubeSats release is commanded by Aki's operation.
2nd release will be commanded by ground.

Next, We need watch the SpaceX CRS-1 mission.

10/04/12 NASA ISS HP
http://www.nasa.gov/mission_pages/station/living/index.html
A backup robotics workstation in the Destiny lab experienced a trip in a remote power control module (RPCM) overnight. Williams reset the workstation and installed a jumper between another RPCM and a control electronics unit to maintain power to the robotics system. Mission rules state that both robotics workstations in the cupola and the Destiny lab must be operational before the SpaceX CRS-1 launch.


ISS On-Orbit Status 10/02/12
http://www.nasa.gov/directorates/heo/reports/iss_reports/2012/10022012.html
To prepare for a possible repeat of a trip of the Lab RWS RPCM (Robotic Workstation Remote Controller Module), required for Dragon berthing, Suni gathered material to provide for an alternate power source, if needed, and reviewed CEU procedures that use pre-built cables from the ISS Pin Kit to re-route power to the CEU.

From Novosti Kosmonavtiki : first and successful test of SLS laser comm system in 2nd october !

Quote
05.10.2012 / 09:38   2 октября 2012 года с Российского сегмента Международной космической станции впервые по лазерному каналу была передана широкополосная информация на наземный пункт


      В рамках космического эксперимента (СЛС) по отработке аппаратуры и демонстрации российской технологии создания космических лазерных систем передачи информации, проводимого ОАО «НПК «СПП» совместно с ОАО «РКК «Энергия», осуществлен сеанс передачи информации с терминала связи, установленного на борту РС МКС, на лазерный терминал наземного пункта станции оптических наблюдений «Архыз» на Северном Кавказе (филиал ОАО «НПК «СПП»).
      Была передана информация общим объемом 2,8 Гигабайт со скоростью 125 Мбит/с.
      Этот шаг открывает дорогу к широкому внедрению в космическую технику России лазерных линий связи, которые при меньших массогабаритных параметрах бортовой аппаратуры потенциально могут обеспечивать исключительно высокую скорость информационного потока (до десятков гигабит в секунду), сообщает пресс-служба Роскосмоса.

During this morning's Weekly Planning Conference it was mentioned that there would have to be extensive replanning of the next few weeks because an EVA has been scheduled.  Apparently the crew was notified of this yesterday(Oct. 5).
