* Mandarin Pinyin (transliteration) : Tōngxìn jìshù shìyàn wèixīng yī hào
English name discrepency: TXJSSY 1, TXJSSY 1, communication technology experimental satellite, First Communication Technology Experiment Satellite, TJSSW 1


2015/09/13

Launch from Xichang SLC confirmed at 23:42 Beijing Time, on September 12, of TXJSSY-1 (通信技术试验卫星一号) or "experimental communication technology satellite 1", code named satellite 07-66. Track is consistent with a GEO sat.

The TXJSSY-1 satellite will be used to perform tests on the Ka frequency band in broadband communications. Ka band represents an important advantage, as the slots in the GEO orbit is almost saturated, as far as C and Ku band are concerned, which greatly limit future operations.

This is China's fifth successful launch this year (208th overall).

Since the OP really can't explain clearly what is going on, let me elaborate:

Yup, the Chinese have launched another satellite again! This time though, there's no official news coming through even at this moment 2 hours after a Long March 3B rocket lifted off from China's Xichang Satellite Launch Center at around 15:40 UTC (yup, no exact launch time reported yet :shifty. Unofficial reports puts the top secret payload as an experimental comsat.

Well.........wait for my report when all the Middle Kingdom Black Veil surrounding it settles down. :uhh:

In the evening of September 14, debris recovery team found the TXJSSY-1 satellite payload fairings in Jiangxi province, Zuo'an Town, Yangxi village, Huangguoping Mountain. The two satellite payload fairing wreckages were only distant of less than five meters from each others.

Let "Google search" decide::hmm:

As we can see, this thread (TXJSSY-1) ranks 3rd, only two German websites rank better, and we are even ahead of the first French forum. First following English website, in 5th position (which posted poorer English translation...):rofl:

 

[Cosmic Penguin]

Well, is this thread still sounding confusing to you guys right now? No worries, because the Chinese are still pretty mum about this launch! :rofl:

As mentioned earlier, the 28th Long March 3B rocket lifted off from Xichang Satellite Launch Center's pad 2 two days ago at 15:42 UTC. Apparently even nearby residents don't know about this launch and (according to local reports) rocked the dormitories of the local college so hard that lots of freshman students (who probably never experienced a rocket launch before) mistook it for an earthquake (pretty common there) and all rushed down the stairs to the ground, mixed with screams of the girls! :rofl:

The rocket did its job and deployed the top secret payload about 30 minutes after launch into a standard geostationary transfer orbit. And....that's about what we know about the satellite! "TJSSW-1" is the short form of "Communication Technology Experimental Satellite 1" in Mandarin, and the official reports mentioned that it will test out broadband communication technologies in the Ka-band. Well, we all know that the Ka-band of the microwave spectrum has been a very active territory in satellite communications (especially for satellite Internet links and satellite HDTV) and the Chinese haven't deploy any comsats making use of the Ka-band before this one, but with no-one in public actually know that this satellite actually exists, who knows what else is on board this mysterious thingy? :rofl:

The Great Chinese Spaceflight Mystery September continues with yet another secret launch occurring right as I am writing this post. Wait for my report on that one! :tiphat:

This means that "TXJSSY-1" is a GEO electronic signature reconnaissance satellite

Xi'an Institute of Space Radio Technology (XISRT) deployable truss antenna has a 6-30 meters diameter. TXJSSY-1 large aperture deployable antenna is probably this one in the picture

SPECTACULAR Photos of a Rocket Re-Entering Over Hawaii!



Around 2:00 a.m. local time on Saturday, Jan. 30, 2016, astrophotographer Steve Cullen was driving home from visiting the summit of Mauna Kea on the Big Island of Hawaii. He stopped at around 11,000 feet to take some panorama shots of the peak… but what he got was much more.

He noticed an orange light heading up into the sky out of the west. It was moving across the sky at about the speed you’d expect from a satellite, but at that time of night no satellite moving at that rate would be lit by the Sun, so it wouldn’t be visible.

Within seconds, though, it became clear what he was seeing: some sort of human-made space debris re-entering Earth’s atmosphere. How?

Because this. Check. This. OUT.

http://www.slate.com/content/dam/sl...ineserocket1_1.jpg.CROP.original-original.jpg

HOLY WOW! What a shot! (Click the photos for bigger, higher-resolution versions on Cullen's Facebook page.) Over the foreground of volcanic rock and more distant clouds (seen from above at that elevation), the debris came streaking toward the east, seeming bursting forth from the constellation of Orion (can you see it behind the trails?).

It turns out this was almost certainly the remains of a Chinese Long March rocket body, predicted to burn up over that area at around that time.
