Astronauts get medical examinations - they are in good condition. The Shenzhou 6 landed about 1 km from designated target.

Astronauts emerged from Shenzhou 6.

Great coverage in CCTV 9 channel from China (although I am in Israel I have this channel).

Some pictures of the astronauts outside the Shenzhou 6.

That's an interesting image showing the Shenzhou-6 descent module after landing.

There appear to be black shuttle-like tiles on the underside for thermal dissipation during the entry phase.

If these tiles covered the base,over half are missing in the image and several others are peeling away. This may be due to ground handling (?) since the underside exposed where tiles may have been appears clean and 'unsooted' ?

Looking at different Shenzhou images, it looks like there may be a 'saucer shaped' dish that forms the DM base. Sandwiched between this and the interior base would be these thermal tiles.

Not sure why they would want remove this dish shaped base at the landing site? And, if they did (as appears to have happened on this mission) did they rip off some tiles?

Or, are these thermal tiles only the DM leading edge where most heat experienced?

There are no thermal protective tiles on the Shenzhou. The heat shield is made of ablative material, and is jettisoned a short time before the landing to reveal the clusters of solid fueled retro rockets.

I think that the "tiles" are just spacers.

I don't see why they would use small rectangular tiles when they could use either a lightweight cruciform (or similar) metal (with holes in it to further reduce weight) to support outer base shield or several larger mats instead?

I would have thought the outer base shield could have been attached to the main DM body without need for spacers anyway?

I'm looking for other Shenzhou images of the base shield/s to try and compare against Shenzhou-6.

This was said earlier today:

"...CRIST President Yuan Jiajun said the buffer engine of the capsule ran well before landing and remained intact, and the burning of the outer shell was normal.

"The heat-proof structure of the capsule wall has kept intact and the capsule is still hermetic, which indicates the successful re-entry of the spacecraft," he said..."

I've been examining a couple of images of Soyuz DM bases and they have somewhat similar rectangular pads - although in the image (lo-res off web) the pads appear to be 'linked' by smaller 'linking pads'? On Soyuz I wonder whether they protect cable routings?

You may well be right about them being spacers. I don't see why only in one quadrant area of the base though? Certainly the Shenzhou-6 pads are peeling away from the 'inner base'. Are they affixed by adhesive? Same positioning as on Soyuz? Need check this last bit.

The UK NSC Soyuz full scale 'model' unfortunately doesn't show the base very well and may well have the base shield still in place anyway. I'll look through my images from there but don't think it will help.

If you've any tech docs or manuals (or web links) on the Soyuz or - dare I ask - Shenzhou base heat shields let me know!

I have several pieces of a Soyuz heat sheild... I will try to locate some information from my books.

AFP: Orbiting Chinese space capsule returns to earth
The orbiting capsule of China's Shenzhou VI spacecraft, which was launched into space six months ago, has returned to earth after orbiting 2,920 times.

The orbiting capsule was left in space after China's second manned flight returned home, Xinhua news agency said Saturday.

Astronauts Fei Junlong and Nie Haisheng became instant celebrities after returning from the five-day mission in October.

Xinhua said the orbiting capsule successfully gathered scientific data during its 180-day mission that involved a series of tests and experiments.

Some are reporting this to be a mis-translation; that in fact its mission is over but has not been deorbited.

I had someone confirm with spacetrak that it is still in orbit.
