Thanks! Mystery solved
As I understand it Phenylon® is a Russian tradename for a material equivalent to Dupont's Nomex® - otherwise know to chemists as poly(m-phenylene isophthalamide) or PMPI for short.
This is a high-performance polymer, with high thermal and mechanical resistance, described by Dupont as "inherently flame-resistant, high-temperature fiber that will not melt, drip or support combustion in air. It also delivers outstanding resistance to a broad range of chemicals and is offered in paper, felt, fabric and fiber forms”
The natural color of Nomex® is usually described as "off-white" or "ivory", and many variants are classed as non-dyeable.

Someone asked on a Reddit forum, why is the Orlan spacesuit creamy-colored and not white? Googling brings me no information, only that the outer layer is made of a heat-resistant fabric called phenylon (via this PDF document). Is the fabric that color naturally?
This is something I would also like to know.

2) When was the first Soviet/Russian satellite launched into polar orbit?
Which inclinations do you consider polar?
If 81° is polar enough, this would be Kosmos 144, a Meteor-1 weather satellite, on 28 February 1967
Good enough for me. Thanks.

By the way have you discovered what happened to Bion №12?
No. Are you sure it has ever been built ?

The previous Bion was 12КС №Н15000-11, and the Н indicates it was intended for 1993. It flew at the end of 1996.
Bion №12 was planned for the summer of 1998. NASA dropped it's participation in 1997 after the recovery of Bion №11.

Are there any good overview articles (English/Russian/other languages) on the control rooms (console positions etc) and other equipment of MCC-Moscow/TsUP?

I would like to know too! I have searched but can't find any details (on English sites, at least), and nothing on the
TsUP site. (NASA has an interactive diagram of their own MC on a
page of their site.)

What are
these being worn over the Sokol spacesuits before launch - protective covers? Or is it a new Sokol design?

Definitely a cover, it was extremely cold on launch day. And I'm almost sure I've seen them used before.

Yes, it is a cover to protect cosmonauts from the very cold temperature, developped by NPP Zvezda in Tomilino.
It was their first use, and the last for now.

No; they are wearing special thermal garments, have a look at: http://rsc-etestpilot.blogspot.nl/2012/11/blog-post_20.html

New suits?
Thanks, Nice information. Here is another news.
http://ria.ru/science/20121219/915504283.html
"Equipment does not yet have its own name and is called simply" a thermal kit. "It is very light, does not restrict movement, and with the help of an assistant, is removed from the astronaut in seconds. We are very proud that today our overalls for the first time and successfully used. This heat shield was created by us in record time - just a couple of months from prototyping to production of the first sample, "- said Pozdnyakov.

Did the flown airlock on voskhod 2 have an outer fabric covering over the aeroboom structure? Most of the literature points that it did (unlike the test article now fitted to the capsule at the energia museum). ...But leonovs paintings almost always show the aerobooms visible. Maybe it's artistic license but it seems odd. Did anyone ever ask him?

I'd also like to know the colour of the capsule, and if the air bottles had thermal covers too (and the upper 'tower').
