Rui, is there still any chance of this satellite making to orbit in 2012?
I haven't seen any news about this this from Brazilian sources, but the CEOS page (http://database.eohandbook.com/database/missiontable.aspx) is now giving February 2013 as the launch date for this mission. This information needs to be confirmed.

According to the Brazilian Space Agency, the launch of CBERS-3 is scheduled for next December.
Quote from: Satori on 09/10/2013 04:26 pmAccording to the Brazilian Space Agency, the launch of CBERS-3 is scheduled for next December.Sounds like a good candidate for the primary payload that the cubesat from Poland is launching with.
According to CBERS-3 - China e Brasil lançam ao Espaço ainda em 2013 (in Portuguese) the previously December 27th schedule launch of CBERS-3 was anticipated for the first ten days of that month.The request to anticipate the launch was because of the New Year festivities in Brazil.
CBERS-3 will be launched on December 10 at 0300UTC.

o lançamento do satélite está programado para as 11h do dia 10 de dezembro, no horário de Pequim (zero hora, em Brasília). O CBERS-3 vai substituir o CBERS-2B, que deixou de operar em 2010.
The latest information I got from INPE was that the launch would take place at 10:00 local time, that gives 0200UTC

According with latest information, CBERS-3 will be launched at 0326UTC on December 9th.
Any status reports from the launch site?
It will be 200th Chinese orbital launch if we count KZ launch in March 2012 as orbital launch attempt: FB-1 - 8, CZ-1 - 2, CZ-2 - 4, CZ-2C - 37, CZ-2E - 7, CZ-2D - 20, CZ-2F - 11, CZ-3 - 13, CZ-3A - 23, CZ-3B - 25, CZ-3C - 10, CZ-4A - 2, CZ-4B - 19, CZ-4C - 13, KT-1 - 3, KZ - 2

Probably because some of the launches in the list are not well known even to those interested in orbital launch records (e.g. only some of them have the 3rd KT-1 launch on record, never mind the probable KZ launch attempt last year!). I bet there will be much more interest in the 200th launch of a rocket named "Long March" some time late next year or early 2015....

But I simply thought that there are more kindly relation to space statistics in China. Probably, I was mistaken... It should be noted that only USA very scrupulously counts launches (at least, U.S. statistics about orbital launches can be found on many sites). Okay, nevermind...
In my site, every post about an orbital launch has the specific statistics associated
Any signs of a live broadcast from Brazilian sources? (I guess not?)
Strange, I have seen two different rumors sources saying that something failed........ ......... yet O Globo, the largest Brazilian newspaper, is reporting launch success...
O foguete chinês Longa Marcha 4B cumpriu perfeitamente todas as etapas previstas para colocação do satélite em órbita. O tempo total de voo até a injeção do CBERS em órbita foi de 12,5 minutos. Quando atingido o ponto ideal da órbita, um comando liberou a trava do dispositivo que prendia o CBERS-3 ao foguete. O satélite, impulsionado por molas, afastou-se do lançador e entrou em órbita. Em órbita, o CBERS-3 efetua uma revolução completa em torno da Terra a cada uma hora e quarenta minutos (100 minutos).
Hmm, this Brazilian news report mentions that the launch failed...... [url]http://folha.com/no1382856 [/url
Quote from: Galactic Penguin SST on 12/09/2013 08:16 amHmm, this Brazilian news report mentions that the launch failed...... [url]http://folha.com/no1382856 [/urlSaid to be a launcher failure, satellite failed to reach orbit. The reporter was apparently on site.
Well I wonder if the two governments would decide to build CBERS-5 as a replacement?
This is a very, very sad end to CBERS-3. The all project was doomed with problems in the last months and one almost could imagine that something would go wrong. But, I wouldn't expect a failure in the launch vehicle.
So, the problem was with the last stage of the CZ-4B (?)
Sad news for the Brazilian team involved.
Or, was there no one present from the Brazilian side at the launch?
Lançamento do CBERS-3Segunda-feira, 09 de Dezembro de 2013 Às 11h26, hora de Beijing (1h26, hora de Brasília), desta segunda-feira (9/12), o satélite CBERS-3, desenvolvido conjuntamente por Brasil e China, foi lançado pelo veículo chinês Longa Marcha 4B, do Centro de Lançamentos de Satélites de Taiyuan, China. Porém, houve uma falha de funcionamento do veículo lançador durante o voo e, consequentemente, o satélite não foi posicionado na órbita prevista. Avaliações preliminares sugerem que o CBERS-3 tenha retornado ao planeta. Engenheiros chineses responsáveis pela construção do veículo lançador estão avaliando as causas do problema e o possível ponto de queda. Os dados obtidos mostram que os subsistemas do CBERS-3 funcionaram normalmente durante a tentativa de sua colocação em órbita. Para assegurar o cumprimento dos objetivos do programa CBERS, Brasil e China concordaram em iniciar imediatamente discussões técnicas visando a antecipação da montagem e lançamento do CBERS-4.
I made a rough estimate based on CBERS 2B and an 11s shortfall in the burn and 720 km apogee.I get an orbit around -153 x 720 km x 98.5 deg, with impact in the Antarctic around 0407 UTC.However, the uncertainties are large.

Something like 270 meters/second short, give or take. - Ed Kyle
According to INPE (quoted by Globo), the cause of the failure was a premature cutoff of the 3rd stage engine 11 seconds earlier than nominalThe altitude reached was 720 km instead of 778 km planned. The velocity reached was not enough to maintain an orbital flight(source in Portuguese: http://g1.globo.com/sp/vale-do-paraiba-regiao/noticia/2013/12/corte-antecipado-na-propulsao-impediu-cbers-3-de-manter-orbita-diz-inpe.html)

Any launch pics in the offing..?
Hmm there are reports that the rocket used on this launch has been stored for several years already (in fact someone said that it's CZ-4B s/n Y10), and it might already been in Taiyuan since late last year. Long storage issues maybe?

I guess that's possible - and may even have been programmed - if your U/S doesn't have restart capability, then there' nothing you lose by triggering satellite sep through a timer linked to engine cut-off? (Yeah, maybe RCS can give you some dV, but it's nothing the satellite couldn't do on its own..?)
Infantile behaviour, revealing true colors of a prison-state...if we don't publish launch pics it didn't happen.
Very unfortunate loss. Just wondering whether the Chinese insured the Satellite or Brazilians?
O governo brasileiro investiu R$ 160 milhões no projeto. O satélite não era resguardado por nenhum tipo de seguro.
$160 million is like ....
That was 160 millions Brazilian Real equivalent to about 69 millions US DollarsCorresponding to the Brazilian 50% share for the program

Peter B. de Selding @pbdesChina Great Wall Industry Corp: Dec. 9 LM-4B failure caused by fuel-flow depletion to engine #2 of 3rd stage. Root cause still unclear.http://www.spacenews.com/article/launch-report/38689china%E2%80%99s-great-wall-cites-fuel-flow-issue-in-rocket-failure"PARIS — China’s launch service provider on Dec. 16 said the Dec. 9 failure of its Long March 4B rocket was caused by the premature shutdown of the second of two third-stage engines because of reduced fuel flow.In a statement, Beijing-based China Great Wall Industry Corp. said the failure investigation, headed by Wang Haoping of the Shanghai Academy of Spaceflight Technology, was continuing to determine the reasons behind the reduction in fuel supplied to the engine"
As far as I know, the rocket had a problem in the mixture of the fuel with the oxidant that controls the level of performance of the rocket and that mixture was flawed. The rocket had its third engine off ten seconds before what was needed, so the satellite speed was not enough to keep it in orbit ", described the [Brazilian communications] minister, who was in China to accompany the launch

The CBERS 1, 2 and 2B satellites were classified as being the Ziyuan-1 programme.Do we know if CBERS 3 was also Ziyuan-1 (in which case, what was its number? - 3??) or whether it was possibly Ziyuan-4 since we have already had flights in the Ziyuan-2 and -3 series?
