(Xinhua) 21:03, May 17, 2017
JAKARTA, May 17 (Xinhua) -- Senior officials of Chinese firm China Great Wall IndustryCorporation (CGWIC) and Indonesian firm Palapa Satelit Nusa Sejahtera (PSNS) Wednesday signed a purchase contract for the latter's satellite system, namely PALAPA-N1, scheduled to orbit in first half of 2020.
PALAPA-N1 communication satellite project is the first communication satellite of Indonesia that is produced by China.
PSNS is a joint venture enterprise of prominent telecommunication firm operating in Indonesia, Indosat Ooredoo, and Pasifik Satelit Nusantara (PSN).
Under the contract, CGWIC is responsible for in orbit delivery of the PALAPA N1. CGWICshall provide a package solution with the products and services to its Indonesian client, including the satellite, the rocket launching service, ground system, insurance andfinancing support.
The PALAPA-N1 satellite, which is designed to replace the PALAPA D, will be launched toits orbit slot at 113°E in the geostationary arc by Long March 3B launch vehicle from the Xichang Satellite Launch Center in China.
PALAPA-N1 will provide the latest technology of High Throughput Satellite for broadcast and broadband telecommunications.
Speaking on the sideline of the signing ceremony, Indosat Ooredoo CEO Alexander Ruslisaid the new satellite would greatly help broadband penetration among the society in Indonesia.
"It would also help accelerating the creation of digital society in Indonesia, support thegovernment's plan to make Indonesia the largest digital state in Southeast Asia," he added.
The contract signing was witnessed by Indonesian Informatics and Communications Minister Rudiantara, Chinese Embassy Charge d'Affaires Sun Weide and Vice President of China Aerospace Science & Technology Corporation (CASC), the parent firm of CGWIC, Yang Baohua.
CGWIC President Yin Liming said the satellite would significantly improve the broadcastand broadband in Indonesia.
"It would also be an embodiment of friendship between Chinese and Indonesian people," he said in a statement.
CGWIC won the contract after undergoing a strict auction process considering technical, manufacturing period and cost efficiency. It brushed competitors from Europe and the United States to get the contract.
The PALAPA-N1 satellite is developed by China Academy of Space Technology (CAST), a subsidiary of CASC.
The PALAPA-N1's satellite system is designed to have lifetime of more than 16 years, to be equipped with a total of 42 transponders.

given that a CZ-2C is scheduled in the near future from LC3 i would expect LC2.

Indonesian Palapa-N1 communication satellite launch failure
Xinhua News Agency, Xichang, April 9th, by wire
At 19:46 on April 9th, China launched the Indonesian PALAPA-N1 satellite with the Long March 3B carrier rocket at the Xichang Satellite Launch Center. The rockets 1 and 2 were flying normally and the third stage was abnormal. Level and satellite wreckage have fallen, and satellite launch has failed. Troubleshooting and related handling work has been fully launched. (Finish)

So launch time is confirmed as 11:46 UTC

It was the first flight of this third stage since the failure of the CZ-7A. Did the CZ-7A fail because of this stage or is it just a coincidence?
-
Seems like there are reports of fireballs in the sky seen around Guam and Saipan that has been linked by local media to be related to this failure. (https://twitter.com/sybil_ms/status/1248253670476546048) The flight path certainly fits in the correct region.
The National Weather Service branch at Guam was notified of this observation. (https://www.facebook.com/NWSGuam/posts/2855897117825871)

From Xinhua,
China's launch mission on Palapa-N1 satellite fails (http://www.xinhuanet.com/english/2020-04/09/c_138962095.htm).

It was the first flight of this third stage since the failure of the CZ-7A. Did the CZ-7A fail because of this stage or is it just a coincidence?
I thought the Long March 7A failed because of a potential second stage issue with the YF-115 engines.

I thought the Long March 7A failed because of a potential second stage issue with the YF-115 engines.
There were three theories but we never got an official confirmation as to which stage failed.
CZ-7A
Engine failure: Plausible in conjunction with theory 2.
Stage re-contact: video showed Stage 0/1 sep from stage 2 then possible re-contact moments later.
Third stage failure in the first burn: no evidence available that I know of.
-
To make it to Saipan suggests (by some rough modelling I did) a -1070 x 210 km orbit, underburn by 420 m/s and 43s duration
short. In other words, I infer that it got most of the way through the first burn before failing, otherwise it would have
fallen nearer the stage 2 drop zone just east of Taiwan.
I am not confident of the accuracy of the calculation but I suspect the general conclusion is correct.

"The third stage has two engines, one of which doesn't fire. So it doesn't get enough speed to enter the orbit," Adi Rahman Adiwoso, Director of PSN, said at the same conference.
"The satellite's altitude was only about 170 km, with a speed of 7,100 meters per second, and then fell into the ocean and could not be saved," he continued.

Long March 3B carrying commercial Indonesian satellite fails (https://spacenews.com/long-march-3b-carrying-commercial-indonesian-satellite-fails/), dated April 9
Though announced as a DFH-4 satellite, Nusantara-2 was built on an upgraded version of the CGWIC platform called the DFH-4E, which could accommodate a more powerful payload, PSN CEO Adi Adiwoso told SpaceNews in an interview before the launch.
-
The failure reason of this launch has shown up in a tender for launch insurance services for ZY-3-03. (http://www.mof.gov.cn/xinxi/zhongyangbiaoxun/gengzhenggonggao/202006/t20200609_3529046.htm) ;)
I expect either the Indonesian customer or their insurer will confirm this later, particularly since they are apparently going back to the Chinese for the replacement satellite.

The new CZ-3B/E which just launched Apstar 6D had the dry mass of the upper stage reduced in mass by 50 kg, which increased payload to GTO by the same amount to 5,550 kg. It just so happens that Palapa N1 also has a mass of 5,550 kg, so I'm guessing this was the first flight of CZ-3B/E. The changes made to the cryogenic stage might have contributed to the failure, although that seems to contradict other reports of the cause of the failure.
https://www.nasaspaceflight.com/2020/04/long-march-3b-launches-indonesian-satellite/
"Weighing 5,550 kilograms, Palapa-N1 had a capacity of 20×36 MHz C-band FSS transponders and 9.5 gigabit-per-second (Gbps) HTS. The satellite can cover regions throughout the Asia Pacific and to Australia for C-band transponders and throughout Indonesia for HTS. The satellite could have also been used for VSAT, broadcast, broadband, backbone, and backhaul services."
