Although we will find out for definite at the end of the year, there's speculation in this March 4, 2008 article that the Chinese taikonaut who "steps out" into space on their next mission might be wearing something more like an American EVA suit rather than the expected Russian Orlan copy.Anyone any info on where they are manufactured? Anyone seen a Chinese spacesuit up close? China recently re-hashed an old artist's conception of its first spacewalk, showing a spacesuit-clad figure emerging from the Orbital Module of Shenzhou, which will serve as an airlock.This image, released in the state-run media, showed a different sort of spacesuit. Earlier pictures showed a spacesuit that resembled a Russian Orlan suit, but the recent one looks more like an American suit. It's difficult to know what to make of this. |

The design of the Chinese EVA spacesuit seems to be a copy of the Soviet Orlan.Has anyone any ideas (or hard facts) to confirm if Zvezda supplied the Orlan "off the peg" to the Chinese? |

On the basis of nothing except the visible evidence, I now think that the Chinese have simply purchased Sokol-type and Orlan-type suits from the Russian manufacturer, Zvezda. Otherwise, why would they seem to copy the suits so perfectly — right down to the blue piping on the Sokol suits (could it really be important functionally?) — while at the same time they modified the basic Soyuz architecture to make it more suitable to their mission needs, instead of just "copying" the Soyuz wholesale? I think the Chinese found the Sokols and Orlans to be "good enough" off-the-shelf, while Soyuz needed modifications to meet their needs. Note that other entities have purchased Sokol suits from Zvezda (for example, the now-dormant British Qinetic and Team ReMax high-altitude balloon projects), so there is precedent. My logic is not conclusive, but it does seem to be the simpler explanation. |

Just when it looked like the mystery was finally solved along comes more intrigue. China has prepared two kinds of outer spacesuits for taikonauts for the spacewalk mission. One was made using China's own technologies, and another was bought from Russia. The country will make the final choice as the space mission nears. |

Shanghai Daily has reported that the taikonaut that will leave the airlock during China's first spacewalk will "wear a Chinese-made space suit." Unlike its American counterparts, the China-made suit will not have its own power system. A cord will link the astronaut with the spacecraft to provide oxygen, power and communications.The suit for the space-walk astronaut on the Shenzhou VII mission was developed by Chinese scientists based on the Russian design, Pang said. The astronaut who remains in the airlock will wear a Russian space suit. However, future missions will exclusively use the Chinese suits. Thus a Russian "off-the-shelf" Orlan spacesuit will fly on Shenzhou VII but so will a "Made in China" version, which will be donned by the taikonaut spacewalker. |

The Chinese EVA spacesuit is called the "Feitian", reports Xinhua: China's Shenzhou-7 astronauts will wear the Orlan space suits provided by a Russian supplier and also the indigenous Feitian suit during the country's first ever space walk, said Wang Zhaoyao, spokesman with China's manned space program on Wednesday.Two astronauts who are scheduled to perform the extravehicular activities (EVA) will each wear the Orlan and the Fetian suit, and Russian experts will provide technical support for the process, retold a news conference at the launch center. According to a contract signed in April, 2004, a Russia company provides three Orlan suits, two low-pressure training suits, four suits for underwater training, and four sets of docking systems in the craft. The Chinese side is responsible for providing power and communications equipment for some of the EVA suits. |

I wonder if the difference from the Orlan design around the chest area is just "cosmetic" and it's the same old underneath.Also, it will be interesting to see if they try bring both these two test EVA suits back to Earth in the descent capsule, as there might be enough spare room. Otherwise, they are going to have to leave them inside the orbital module, where they will remain for two years plus in orbit until the next mission. Will they still be usable after that amount of time? |

I haven't seen anything yet to indicate the planned fate of the suits, but I believe the orbital module is expected to be placed into a decaying orbit. There were reports that to ensure the safety of this first spacewalk, the orbital module was launched without its solar arrays, limiting its usefulness post-separation. |

Then I'd be very surprised if they simply leave them in orbit. The Chinese budget surely doesn't extend to throwing away two very expensive spacesuits after only 40 minutes of use?It might be a very tight squeeze but these two suits (or substantial parts of them) are probably coming back with the Taikonauts! |

Interestingly, the Chinese press release today said that the IVA astronaut will be wearing a Russian Orlan suit, which explains the photos of two suits. This is going to be something neat! |

The suit design is certainly interesting. I see elements of Orlan and others that tend to resemble an EMU in it. So unlike the launch and entry suits the Chinese use which seem to be based very closely on Sokol, these suits seem to be unique. Plus I see something that almost looks like a SAFER unit strapped to the bottom. Nice work! |

I think that what you see as a SAFER-type unit may be the housing for a computer.The Feitian appears to use a display and control module (DCM) similar to that of the Orlan MK, which has an LCD display. Its computer is at the base of the portable life support system backpack. |
