From China.org (in Spanish): ESPECIAL: CBERS, la joya de la corona de la cooperación tecnológica Brasil-China.

So. according to this article, CBERS-3 is going to be launch 'in the next weeks'.

That begs the question of whether it or HJ-1C is launching first; unfortunately getting any launch updates from TSLC is notoriously difficult....

I agree. But 'in the next weeks' is something very vague...

I think that the article in spanish is a translation of the article published by Xinhua a few days ago.

'Espaço Brasileiro' ('Brazilian Space') on-line magazine available at http://www.aeb.gov.br/wp-content/uploads/2012/09/RevistaAEB_n13.pdf (in Portuguese) has an article about the CBERS-3 satellite.

So, with the possible schedule launch of HJ-1C on November 12, the launch of CBERS-3 can only take place in December.

According to Opto envia à China câmera do satélite CBERS-4 (in Portuguese), the launch of CBERS-3 will take place in January 2013.

The news is about the transport of the MUX camera to China to be used on the CBERS-4 satellite.

According to CBERS-3: Lançamento Pode Atrasar Até Dois Anos, Será? (in Portuguese), the launch of CBERS-3 can be delayed until two years because of the problems encountered with the DC/DC converters. In the other hand, looks like there are strong political demands to launch the satellite as soon as possible.

The article also talks about a February 2013 launch date.

On December 6, the INPE (Instituto Nacional de Pesquisas Espaciais) contracted two companies to work on the problems on the CBERS satellites.

The Mectron company is going to re-project and substitute the IN-RUSH Circuit and change the DC/DC converters on the MV1, MV2 and MV3 transponders of the TTCS subsystem on the CBERS-3 and CBERS-4 satellites.

The Equatorial Sistemas will rework the IN-RUSH Circuit of the FM1, FM2, FM3 models and will change the DC/DC converters of the models FM1 and FM2 of the SPE from the WFI subsystem of the CBERS-3 and CBERS-4 satellites.

Information about the contracts can be seen at http://brazilianspace.blogspot.pt/2012/12/aeb-assina-quatro-novos-contratos-de.html

So probably we will see a larger delay on the launch of CBERS-3, but there are no official informations about this.

The Brazilian Space Agency says that one of its main priorities for 2013 is the launch of CBERS-3. Nut, some specialists say that the tests and integration of the new DC/DC converters is a process that should take one and a half to two years, and that the launch should be delayed (as well as the launch of CBERS-4 schedule for 2014).

So, many think that here is a strong political pressure to launch CBERS-3! We should ask if China is willing to launch a satellite with a strong probability of failure in orbit?

We now have the confirmation of the delay of the launch of CBERS-3 that will probably take place in May or June 2013 ( Falhas Técnicas Obrigam Brasil a Adiar Lançamento de Satélite com a China in Portuguese).

Interestingly, there are strong political pressures in Brazil to launch the satellite next month. I see this as a prescription for disaster and even the May or June dates are very ambitious.

Apparently, and contrary to what was said early, the CBERS-3 will still be using the DC/DC converters manufactured by the American Modular Devices Incorporated (MDI). Some converters didn't pass the tests that were made in China. Some 20 devices were sent to the US to be tested there and 12 of those converters failed the tests. MDI concluded that not all the devices had problems, so the problematic ones were replaced.

The decision to delay the launch to February was took on November 20. Now the launch is schedule to May/June period.

Lets remember that recently two Brazilian companies were contracted also to supply the DC/DC converters, but it looks like if those converters were to be used on CBERS-3 then the launch would have to be delayed almost two years because that's the time needed to rearrange and test the satellite electrical system to operate with the new converters.

CBERS-3 camera after a thermal vacuum test. It looks like indeed that the satellite is on schedule for launch in May-June.

OK I think my message above doesn't make sense - maybe it's for CBERS-4?

Bad news for CBERS-3 :( Looks like new tests made on the «new» DC/DC converters this month had very bad results.

At this time I doubt the satellite will be launched this year or if it is launched, the Brazilian part of the satellite has a great probability of failure.

As I remember, the Brazilian contribution to the second CBERS also cause a great deal of concern and delay.
