Title: FAILURE: CBERS-3 Long March-4B launch, Taiyuan - December 9, 2013 (0326UTC)
Post by: Satori on 04/01/2012 01:16 PM
China and Brazil plan to launch the CBERS-3 remote sensing satellite in November 2012.

Compatibility tests took place between February 29 and March 7 in China.

On March 30 the Brazilian company 'Opto Eletrônica' sent to China the MUX camera that will be used on the CBERS-3 satellite.This camera will be used to environmental monitoring and remote sensing of natural resources.

MUX mass is 120 kg and has a 20 meter resolution (CBERS-3 will be orbited at 750 km altitude).

(Note the out of focus area on the image that shows the camera being prepared for shipment to China)

In China, it was completed another stage of CBERS-3 satellite testing before its launch, arranged for the end of the year. Experts of the National Institute for Space Research in Brazil (Instituto Nacional de Pesquisas Espaciais – INPE) and of the China Academy of Space Technology (CAST) have checked the satellite self-compatibility and its electromagnetic compatibility with the launch vehicle.

These tests are necessary to prove that a satellite equipment does not interfere with another one. The simulation on Earth of all the conditions that the satellite will face, since its launch by the end of its life in space, is indispensable due the inability to repair it in orbit.

Before leaving for China, CBERS-3 had all its equipment and subsystems tested at the Integration and Testing Laboratory (LIT) of INPE, in São José dos Campos (SP).

In Brazil, the satellite has undergone several tests for electromagnetic interference and compatibility, vibration, vibracoustic and thermal vacuum further to the mass properties measurement. Now, in China, the final tests to CBERS-3 launching qualification are underway.

Efficiency

The use of satellites allows an efficiently and economic monitoring of environmental changes, both natural and those caused by humans. The observation from space is even more important for large countries such as Brazil and China.

In 1988, both countries established the CBERS Program (China-Brazil Earth Resources Satellite) to join efforts for knowledge on Earth Observation. Three satellites have been launched - CBERS-1, in 1999, CBERS-2, in 2003 and CBERS-2B, in 2007. The fourth satellite, CBERS-3, is scheduled for late 2012, while CBERS-4, for 2014.

Satellite images are essential to collect information about Earth's surface, either necessary to assess global change, forestry, agribusiness development, urban and coastal studies. Satellites are also essential to quickly obtain information about events whose location and occurrence is difficult to predict or access, such as natural disasters (floods, for example), or produced by humans (forest fires, pollution caused by oil spills at sea).

INPE daily distributes hundreds of satellite images by the internet to 1500 public and private institutions in Brazil. The availability of CBERS data allows the development of new applications of remote sensing in Brazil.

Will the CBERS-3 launch be delayed?

The launch of the CBERS-3 sino-brazilian remote sensing satellite can be delayed for a few months. The cause? Some failures were identified during tests conducted in China before the satellite could be sent to the launch site. The failures were detected in some DC/DC converters on the satellite power system.

Between 18 and 24 of August, five engineers from the Instituto Nacional de Pesquisas Espaciais (INPE), including the coordinator of the Segmento Espacial do Programa CBERS (CBERS Space Segment), went to the UNited States for various meetings to clear out the non-conformities and the failures of the DC/DC converters (made by the MDI - Modular Devices Incorporated), and to be used on the CBERS-3 and CBERS-4 satellites. These components were brought in 2007 and 2008 and were not affected by the ITAR restrictions.

The CBERS-2 satellite suffered from the same problem on the DC/DC converters before its launch, that led to a delay of several months.

CBERS-3 launch will probably be delayed by some time (months?) because of the problems that were found on some components of the power subsystem. The delay is being discussed between China and Brazil.

Apparently this launch can still be taking place this year. The electrical tests have been completed and the satellite is now on the environmental tests. A high effort has been taking place to launch CBERS-3 this year with the Brazilian INPE sending more specialists to China to help with the preparations (resulting some delays on the preparations of other Brazilian satellites).

Still, we have to wait and see further developments on this.

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.
Title: Re: CBERS-3 CZ-4B launch, Taiyuan - February 2013
Post by: Satori on 01/16/2013 12:55 PM
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?
Title: Re: CBERS-3 CZ-4B launch, Taiyuan - TBD 2013
Post by: Satori on 01/18/2013 05:15 PM
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 (http://brazilianspace.blogspot.pt/2013/01/falhas-tecnicas-obrigam-brasil-adiar.html) 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.

It's worth noting that CBERS-2B, which CBERS-3 is supposed to replace, was launched at 11:26am (Beijing time)

That would require some deviation from the planned SSO LTDN of 10:30 (https://directory.eoportal.org/web/eoportal/satellite-missions/c-missions/cbers-3-4) - the earlier CBERS satellites were launched at 03:15, 03:16 and 03:26 UTC respectively, and I don't see any reason to move to an earlier launch time.

About the launch time...

Originally, Leonel Perondi, Director of INPE said that the launch would be on December 10 at 11:00 local time, also saying that the launch would take place at 00:00 Brasilia time.

Until February 16, 2014, Brazil will be on Summer Time (UTC-2h, and a 10 hour difference for Beijing). So, if the launch takes place at 11:00 local time, this will be 01:00 in Brasilia (and 0300UTC).

The information INPE told me was that the launch would take place at 10:00 local time, that is 00:00 in Brasilia (0200UTC).

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....

Not well known, and as far as I know  for both those you mention, not confirmed to be real. (I welcome suitable evidence on this point)

Still nothing from the Chinese side. I wonder if there's something wrong with the satellite (especially considering its history) - it seems that both sources that I have mentioned above comes from CAST and not SAST, so I don't think there's a problem with the rocket. And there are many cases in history that initial satellite problems after launch were solved eventually.......

INPE press release doesn't say much on satellite health
Quote from:  INPE Press release
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).

CBERS-3 was inserted in a wrong and lower than planned orbit.

The solar panel opened as expected and send telemetry signals during 15 minutes before reentering.

So, the problem was with the last stage of the CZ-4B (?)

Or one of the lower stages underperformed and the last stage was just unable to compensate. Let's wait for facts.

Did someone at INPE jump the gun issuing a prepared press release after the rocket nominally flew beyond tracking camera range? I'm assuming whatever anomaly occurred happened after this, because otherwise they wouldn't have issued the "mission successful" release in the first place... they'd have been able to notice the controllers/ plots etc.

Wikipedia says Taiyuan is a civil+military pad, and functions as an ICBM launch site? I bring it up because I don't know how launch pad access and security work.. Are satellite customers (in this case some INPE representatives) allowed to be present at the launch centre? Or, was there no one present from the Brazilian side at the launch?

TAIYUAN, Dec. 9 (Xinhua) -- China's high-resolution remote-sensing satellite Ziyuan I-03 failed to enter orbit after its launch earlier Monday, military sources said.

"The rocket malfunctioned during the flight, and the satellite failed to enter orbit," said the sources, adding that Chinese and Brazilian experts are analyzing the cause of the failure.

The satellite, jointly developed by China and Brazil, was launched at 11:26 a.m. aboard a Long March 4B rocket from Taiyuan Satellite Launch Center in north China's Shanxi Province.

Lançamento do CBERS-3

Segunda-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.

According to INPE (quoted by Globo), the cause of the failure was a premature cutoff of the 3rd stage engine 11 seconds earlier than nominal
The altitude reached was 720 km instead of 778 km planned. The velocity reached was not enough to maintain an orbital flight

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.

Thanks Jonathan. I'll use that, while noting it's an estimation.

I was skeptical at first, since this third stage is supposed to burn for more than 6 minutes, but it turns out that 11 seconds is all it takes with this relatively heavy payload to fall short - way short.  Something like 270 meters/second short, give or take.

I got 270m/s at first, but when I included some planned residuals (I estimated 600 kg of resid prop given
the difference between the burn time and the estimated potential burn time given max prop load) it came
down to 240 m/s.  Mind you, the error bar on that resid is probably +/- 100 percent.

Just read about the failure from the news article. Very sad news indeed.
I have to wonder if, being that there was Hydrazine on board, and if indeed it did crash on Antarctica, if any would have survived re-entry?

AIUI, that post seems to imply that satellite separation happened... even though the stage didn't achieve orbit.

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..?)

That is actually pretty common - automatic separation after final stage shutdown - and indeed has occurred plenty of times
on late-phase launch failures.

Since people do go to Taiyuan to watch rocket launch, I'll see if anyone posts in Chinese forums. But I doubt it, as it is considered bad luck to do so. Especially with CE-3 about to land soon.

There is pic of the rocket just before launch though.

One off projects are usually not insured, but self-insured. In particular, this mission was made by bartering parts, so determining an actual price, would be very difficult, and much of it would be research and not replacement cost.
But more in general, one off projects like these, where there's not a clear economic return, and specially since they have already developing a replacement (CBERS-4), there's no point in the extra cost of insurance. Besides, insurance goes to the general government budget and not to the space agency, so they wouldn't get it anyways.

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

After today's successful launch of GF-2, a bit more information about this botched launch has come out:

- due to blockage in one of the 3rd stage engines, it did not provide enough thrust to reach the planned velocity of 7.9 km/s, instead CBERS-3 was released at only 7.1 km/s.
- after the botched launch SAST pulled back the rocket used today back to Shanghai for detailed inspection - every single engine to be used for future flights has been carefully tested and all pipelines has been inspected for foreign objects.
- new pipelines has been added (around the filters I guess?) to make it triple redundant

 Not too dissimilar to some of the issues Russia had with the Proton 3rd stage over the years. I have no idea, but maybe hypergolic engines are more prone or sensitive to debris in the lines for some reason. Just speculating.
