Re: Chinese Satellites

It was confusing for me when I saw the story. It's certainly not plastered on the front page as a Chinese failure like they would. This one supposedly had one of these experimental satellites. Still there's something wrong with the reporting here. This observation satellite was successfully launched and they launch an experimental satellite the same day? Have they launched two satellites in one day before?

Re: Chinese Satellites

I guess it's a partial failure, the satellite was put into an orbit some 100km too high

Indeed, it was two different launch, two different booster, two different satellite.

The Haiyang 2A is successful, the experimental satellite 实践十一号 04, was officially announced failure, or as LesAdieux said, partial failure.

The booster is also "experimental" (in a sense), although it have 100% success rate before this incident, the booster is a newer type, undergos less launches than others.

失败是成功他妈。 Failure is the mother of success.

Re: the satellite didn't reach the intended orbit due to the malfunction of the LM-2

this is the first launch failure since 1996

Probably the second (partial) failure. A long march rocket, launching the Indonesian owned Palapa Satellite, suffered third stage partial failure but the satellite was able to be maneuvered into working orbit at the cost of having to use up a big chunk of its onboard fuel.

That would probably reduce the operation lifetime of the satellite. Satellites need to routinely launch themselves to higher orbits since drag caused by the atmosphere (a very thin one) in Low Earth orbit could cause their orbits to deteriorate.

The satellite has a designed lifespan of 15 years but now, because of the unplanned fuel burning during the orbital correction, has only enough fuel to last for 10 years.

it wasn't too bad than :)

launch of Tiangong - 1 on hold, waiting for the investigation report of the LM-2C

the unsuccessful flight of the LM-2C last week has put the launch of Tiangong-1 on hold, the announcment by China's manned spaced programme says the Tiangong-1 and the LM-2F are ready to fly, although the mission uses a different rocket, for safety reason, the launch administration is waiting for the investigation report on the recently failed LM-2C flight.
