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.

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.

The satellite has passed the pre-delivery reviews on October 12 and will be transported to TSLC soon for launch in early December: http://news.xinhuanet.com/politics/2013-10/17/c_125556330.htm
