I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.
What we do. Every page goes through several hundred of perfecting techniques; in live mode. Quite the same Wikipedia. Just better.

Kosmos 772 (Russian: Космос 772 meaning Cosmos 772) was an uncrewed military Soyuz 7K-S test. It was an unsuccessful mission as only one transmitter worked. Only the 166 MHz frequency transmitter operated, all of the other normal Soyuz wavelengths transmitters failed. [1][2] The experience from these flights were used in the development of the successor program Soyuz spacecraft the Soyuz 7K-ST.[3] [4][5][6][7][8]
