There are a variety of unconfirmed stories about this.

Known facts: About 1980 a senior officer in the technical intelligence department of the GRU offered his services to the Surete (French FBI). He was code-named FAREWELL and supplied the West with the names of all the GRU agents and informers. Certain US agencies supplied these agents with a vast supply of bogus information. Eventually, FAREWELL broke down under the strain of being a defector-in-place and murdered his girlfriend in front of a bus stop full of horrified Moscow commuters.  There is a good book about this case (and a not-so-good French film).

Rumors: The FAREWELL disinformation package included a lot of deceptive information about the US Space Shuttle. Supposedly NASA supplied the GRU with technical reports on proposed sub-systems that had been rejected in favor of other approaches. Some of these reports led to differences between Shuttle and Buran which are otherwise inexplicable.

The most common claim is that disinformation led to errors in the tiles, tile mountings, or inter-tile spacers, which failed badly during re-entry. The Russians never have admitted this.

Another claim is that Buran's "green" GOX/Kerosene RCS thruster system worked very badly. The GOX supply was replenished from the LOX tanks of the OMS system by burning a small amount of kerosene, which contaminated the GOX with water droplets and soot. The water was (mostly) separated out, but the soot went on to foul the igniters in the thrusters. According to this rumor, several thrusters were not firing properly after only two orbits. A similar system was the original baseline for the Shuttle Orbiter, so it seems logical that it was supplied in the FAREWELL disinformation program.

The truth about all this is buried in secret files. Don't expect them to be opened soon.

One  of the main problems was TPS damage. Seven heat protection tiles were lost and many more were damaged. The worst was on  the left wing, where three tiles were lost in the same location, allowing  hot plasma to enter and damage the wing's titanium structure on reentry.
You can do a forum search or google "Buran tile damage"..

Why don't you link to it then? Here it is: http://forum.nasaspaceflight.com/index.php?topic=636.msg1426568#msg1426568   - and images: http://www.buran-energia.com/bourane-buran/bourane-versvol-etatbouclier.php

The damage is difficult to assess from that single image, but in general the damage of Buran's structure seems to be exaggerated by many based on little evidence such as this image. It was also common and natural tendency during (and post-) cold war to minimize achievements of the Buran program in the west. Such as "the whole structure was warped! It would never have flown again", and so on. This is the first time I have seen those images, and other than that group of tiles missing at the wingtip, the tile loss appears to have been quite minimal. That wing damage looks like it would have been repairable if the program wasn't already dead when Buran landed.  :)

According to Valery Timoshenko (a leading scientist of NPO Molniya), this damage was produced by a "seal defect" in the joint of tiles with section #22 (C-C) of the wing leading edge.

According to yesterday's TASS report the trucks carrying the various parts of Buran were to depart Moscow on June 29 and arrive at the port of Kavkaz (on the Kerch strait in the Stavropol region) on July 3. There they will be loaded onto a sea-going vessel and leave for Sochi, with arrival at the Imeretinskiy port in Sochi expected on July 5. From there Buran will be transported to the Sirius Educational Center.  Refurbishment work is expected to take 1.5 months. Buran will be part of a permanent space exhibition at Sirius that will open in early 2018. It will be joined by a full-scale mock-up of the cancelled Kliper spacecraft and may eventually also be joined by a full-scale mock-up of Federatsia.

A very bad news...  :-X

According to Vadim Lukashevich, editor of the site "Buran.ru", the owners of the mark "Buran" have requested to the Russian justice the closure of the site, due to the unauthorized use of the mark "Buran".

If this measure were taken, a valuable source of information on Soviet and Russian cosmonautics would be lost.

https://vk dot com/wall-47256091_199570

Google translate:

The Buran.Ru website is closed at the request of the copyright holder

The founder and owner of the site "Buran.Ru" Vadim Lukashevich said that the owners of the trademark "Buran" sued in order to close the site.

The site buran.ru contains the richest archival documentary, photographic and video materials on the history of the Russian aerospace industry. The author of the site conducted a complicated and painstaking work to recreate models of space vehicles and aerospace systems in 3D models, to document the achievements and technical solutions implemented in the development of the Spiral, Buran, Energia, Mriya and other systems. Materials collected on the site are of interest to anyone who is interested in the history of Soviet and Russian astronautics.

Illustrations made by Vadim were repeatedly reprinted on websites and in the press, repeatedly stolen by the publishers of calendars, books and even textbooks for aerospace universities.

An hour ago a message appeared:

"LLC" LenTa Wanderings "filed an official application with the court to close the site www.buran.ru in connection with the illegal use of the registered trademark without our consent."

Domain buran.ru is registered personally on Vadim, but all illustrations on the site have a "Buran" logo to which its owners have claims.

Vadim Lukashevich commented on his Facebook page

"I will lose this court. Who is valuable or interesting content of my site www.buran.ru, which was created almost 19 years - copy yourself a website in whole or in parts ... "

After some delays Buran vehicle 003 has arrived in Sochi. It will take about 1.5 months to assemble the vehicle and it will go on display at the Sirius education centre next year.

Here's some video of today's arrival  from a local TV station (1:20 - 2:25):

I did save the whole site, as Vadim requested. It took a week though, as the site's upload is 24 KB/s! Many thanks to Vadim for his work, and I hope he wins the court case!

A monument to the Buran space shuttle will be installed in Tushino (Moscow), near the manufacturing plant of the Buran

From Google Translate:

Deputy Chairman of the Moscow City Duma Commission for Education Olga Yaroslavskaya proposed to install a monument to the space ship Buran in South Tushino, the Moscow Agency reported.

Yaroslavskaya noted that the main enterprise-manufacturer of the ship was the Tushino Machine-Building Plant.

"In order to perpetuate this event and preserve the memory of one of the most important milestones in the exploration of outer space for descendants and pay tribute to the inhabitants of Tushino, thanks to the work of which this event became possible, I initiated the installation of a monument," Yaroslavskaya said.

It is planned that the place where the monument will be located will be a square near the cultural center "Salute". This initiative was supported by the municipal deputies of the district, as well as by the district administration.

The chairman of the commission on monumental art, Igor Voskresensky, said that the commission is ready to consider this initiative.

A new research work between NPO Molniya and RKK Energia: Will Russia build a space drone?

From Google translate:

"Also in December 2015, an agreement was signed with the Energia corporation, we will jointly write the terms of reference for research work on a two-medium unmanned aerial vehicle, which opens within the framework of the Defense Ministry in 2017. The NPO Molniya with RKK Energia old ties, better than us no one knows the features of two-medium devices, capable of working in both the atmosphere and in the airless space. We together created the "Buran", we have established contacts, we will be glad of such cooperation. The Minister of Defense Sergey Shoigu has already signed the documents that this research work will be opened in 2017"

Looks like a reaction to the X-37, much as Buran was a reaction to the Space Shuttle.  Good luck to them!
