I think Russia has the most advanced Space Technology
Space industry of Russia - Wikipedia, the free encyclopedia
NASA is the undisputed leader in Space tech. NASA budget was $18 Billion to Russia's $4 Billion

The fact that you are precisely looking to write India without capital letter really shows what real looser you are

A serious comparison entails objective standards.
China beats U.S., because U.S. does not currently have manned launch capability.
China beats Russia, because Chinese rockets are more reliable and China's 15-year-lifetime 54-transponder satellite technology is way ahead of Russian capability. That is why the Russians used to launch rockets all the time in the 1990s. They had to keep replacing their short-lived satellites.
Today, the Russians are using European tech for their satellites. Therefore, indigenous Russian satellite tech remains vastly inferior to Chinese DFH-4 technology (see below).
China beats E.U., because E.U. has never sent anyone into space.
----------
China's DFH-4 matches Western standards for modern communication satellites
The characteristics of a modern communications satellite are:
1. It is the size of a city bus and weighs about 10,000 pounds.
2. It lasts for 15 years.
3. It has approximately 32 transponders.

Western satellite specifications look identical to China's DFH-4 satellite. (Source: User:Bhamer/sandbox - Wikipedia, the free encyclopedia)
China's DFH-4 is comparable to Western satellites. Its 30 transponders (or perhaps the Pakistanis weren't willing to buy more than 30 transponders) are very close to the average of 32 transponders on a modern satellite. At 5,200 kg or 11,440 pounds, it is approximately the same weight as Western satellites in the 10,000-pound class. The DFH-4 uses the "three primary bands: C, Ku, Ka," and L bands. Its solar panels generate the standard 8 kW of power.

PARIS -- The first of a new line of high-power telecommunications satellites produced in China and already sold to two export customers is scheduled for launch in late October for China's Sinosat direct-broadcast television provider, Chinese space officials said.
The Sinosat-2 satellite, the first of the DFH-4 spacecraft built by the China Academy of Space Technology (CAST), has faced several delays but is now expected to be launched in the coming weeks by a Chinese Long March 3B rocket from China's Xichang Satellite Launch Center in southwest China's Sichuan Province.
If it functions as planned, the DFH-4 satellite design will bring China's domestic satellite manufacturing industry closer to the level of its U.S., European and Japanese counterparts.
DFH-4 is the third generation of China-built telecommunications spacecraft and carries some 800 kilograms of payload -- four times the capacity of the previous Chinese product, the DFH-3. Weighing up to 5,300 kilograms at launch, the DFH-4 platform is built to operate for 15 years -- double the DFH-3's life expectancy -- and provide up to 10 kilowatts of power at the end of its service life.
...
Wang said CAST has tested the DFH-4 design to a maximum capacity of 54 transponders, 38 in Ku-band and 16 in C-band. The satellite's upper limit would be around 5,600 kilograms, he said in the presentation. (article continues)"

what a Joke.
The latest Russian Yahsat 1B satellite uses European technology to allow it to last 15 years.
----------
YahSat 1B (Y1B)
"Al Yah Satellite Communications Company (Yahsat)', a wholly owned subsidiary of Mubadala Development Company, signed in August 2007 an agreement with a European consortium comprising of EADS Astrium /Thales Alenia Space to manufacture an US$1.66 billion dual satellite communications system in time for a launch in the second half of 2010.
The turnkey contract gives the go-ahead for the consortium to use its resources and expertise to design and construct Yahsat's two satellites from design concept to post-launch. Both satellites will be launched within months of one another, allowing Yahsat to provide customers with innovative solutions for broadcasting services, internet trunking via satellite, corporate data networks and backhauling services to telecom operators. The Yahsat satellites will fulfil the satellite communication requirements of both government and commercial customers in the Middle East, Africa, Europe and South West Asia. The system is designed to accommodate the trends of emerging applications in the satellite industry like HDTV and other broadband satellite services.
The operational life of the satellites is estimated at 15 years. The Yahsat system will comprise of a space segment including two operational satellites - YahSat 1A and YahSat 1B. Yahsat 1A is to be stationed at the orbital position of 52.5°E. Both YahSat 1A and YahSat 1B will be Astrium's Eurostar-3000 models. It carries a Ka-band communications payload. The spacecraft will have a launch mass of 6,000 kg and an electrical power of 15 kW."

"A typical satellite has 32 transponders. Transponders each work on a specific radio frequency wavelength, or “band.” Satellite communications work on three primary bands: C, Ku and Ka. C was the first band used and, as a longer wavelength, requires a larger antenna. Ku is the band used by most current VSAT systems. Ka is a new band allocation that isn’t yet in wide use. Of the three, it has the smallest wavelength and can use the smallest antenna." (Source: Beyond line of sight communications)

He asked you if you are underestimating russian capabilities, didnt asked you to copy paste same thing again, bad habbit die hard, isnt it.
And as per your logic, since US is not sending any one in space as per now, so they are behind in technologies. Wow, you forgot that they sent man in space when your ancestors were in diapers. lol.
As per your logic, if tomorow Iran or any other country do a nuclear test, then they will become leader in that as no other country is trying to do a nuclear test as per now. lol at this high IQ

Russian telecommunications satellite lasts only 5 years. Chinese DFH-4 lasts 15 years.
In 1993, the best Russian communications satellite technology lasts only five years.

Kosmos 2251 - Wikipedia, the free encyclopedia
Kosmos-2251, (Russian: Космос-2251 meaning Cosmos 2251), was a Russian Strela-2M communications satellite. It was launched into Low Earth orbit from Site 132/1 at the Plesetsk Cosmodrome at 04:17 GMT on 16 June 1993, by a Kosmos-3M carrier rocket.[1][2]

Everybody is overlooking US mission in planet Mars, which has been an enormous success.
While US satellites orbit planet Mars, US robots are deployed on surface of planet Mars and have provided lot of information. US robots have set a record of durability in planet Mars.

The fact is Chinese still don't have the capability what Russians had in 80s. So, stop Joking I can't laugh anymore.
