It was just mentioned in another thread that ISS crews enjoy sleeping in ATV. Would love to know more about this but would have been off-topic in that thread.
Why sleep in ATV?
Do all crew members have the option of where they sleep? Perhaps only Cosmonauts sleep on the Russian side where ATV is?
I think I also recall a Japanese astronaut slept in the ELM-PS. Perhaps it is nice to sleep in the more remote "corners" of the ISS that may be quieter?
I think the crews enjoy sleeping in ATV since its fans make it a very quiet place to be. The sleeping arrangements on ISS are typically two Russian crewmembers in the Service Module "Kayutas", with the remaining Russian and three US/international crewmembers all seeping in the four Crew Quarter (CQ) racks in Node 2. Crews aren't really supposed to sleep elsewhere since the proper sleep stations offer things like radiation protection, and have alarm speakers to wake the crew in case of an emergency. Koichi Wakata, and afterwards Bob Thirsk slept in the JPM for a brief period in 2009 when there were more people on ISS than there were sleep stations.

People like space. However, technically ATV is not qualified for that (no caution and warning panel, no comm, too much humidity). But, as they say, "in space no one can hear where you are snoring."

I've read somewhere that there are ten WS for MT on the ITS.
But on this document, I see only seven WS...
Someone has a scheme with all ten WS ?
Thanks !

That diagram doesn't show S3-6 so WS 1 is on S3 to mirror WS 8.
WS 9 and 10 were going to be outboard of the SARJ, but the extensions to the MT rails were cancelled at some point. I think it was a cost saving measure, but it might have been part of the post-Columbia manifest reduction.

Watching one of Dr. Don Pettit's videos, I hear him refer to his current home as "Station" and not "the station". I also hear Dr. David Linvingston leaving out the "the" when speaking of it (her?).
Is ISS a proper noun? Is saying "the ISS" wrong?
Skylab, it seems, was just that, "Skylab". It wasn't "the skylab". Was it also referred to as "she" and not "it"?
A space station can be a generic term. Mir was a space station. But when referring to the one that is up there now, it sounds like some folks are calling Station by name.
While on the subject, it makes me wonder why Armstrong said "THE Eagle has landed."
I have a feeling this has been discussed before but I couldn't nail down the search terms.

A link from the Wikipedia Jules Verne ATV page: http://www.esa.int/esaMI/ATV/SEM6IZUG3HF_0.htmlCrewmembers meanwhile are using the European space supply vessel as a new area to sleep and wash I remember seeing a video where an astronaut said he enjoyed sleeping in the ATV (I think it might have been my namesake, Garrett Reisman). I also remember hearing about one of the Russian cosmonauts who was capable of taking a nap anywhere in the ISS; he'd just shut his eyes in the corner of a module and fall asleep within a couple of minutes.

Someone knows the difference between SPDM's OTP and EOTP ?
What is the current status/location of each of them ?
Thanks !

I don't know what the difference is besides EOTP being larger and can potentially hold larger loads. I have attached a photo of EOTP and OTP so you can the difference.
ooh...and EOTP have a FRAM interface, doubt OTP have it based on the photo below.

OTP is Square Grid Interface and No heater Interfaces. EOTP has two FRAM interfaces. OTP is temporary stowed on S0 truss (Zenith side) at STS-130 EVA#1.

Are the current FGB solar arrays removable (they are folded up right now)? If so, could new smaller, shorter arrays be installed so that the FGB could produce some small amount of power? The panels installed on Mir, for example, were transported inside a cargo ship, and extended during the installation process; perhaps similar panels could be installed on FGB.

I thought the FGB solar arrays were just retracted enough to make clearance for the radiators and not completely and that they still produced power.

I don't think they are active, but even if they were, they are so old and degraded that probably not much would be generated.

Weren't they only transported by the Shuttle during the installation of the Mir docking module?

Some were, yes. Others had been transported up earlier.

No attach points or power connections for such panels
