What does the safety briefing cover? I know shuttle crews go through one when they dock, does Soyuz? And what do they talk about in it?

...and I just noticed in this one



Are those wires going to the launch tower?
probably for stability. I never noticed them before.

Thats just reflections of light around the throat. The throat of the SSMEs is a very very small hole in a very very large nozzle (expansion ratio 77:1).

Also, the inside of the Main combustion chamber is covered with a copper alloy, if i remember correctly, for better thermal conductivity, which might explain the reddish color of the reflected light.

That's for protecting the shuttle against lightning strikes. they go to the top of the launch tower, where the main lightning rod is.

Fire, dP/dT (rapid decompression) and the dreaded toxic atmosphere warning.

The ISS is pretty similar to the Shuttle on the US side, but on the Russian side, Shuttle astronauts might get lost easily.

Also the safety warning might include drinking beverages from the Russian side.

Yes. The lightning mast is made of fiberglass and the wires is part of the catenary wire system that leads the lightning strike into the ground protecting the FSS and shuttle from harm.

Default live video

quote.They also opened the Centerline Berthing Camera System on top of the Harmony module. The system provides live video to assist with docking spacecraft and modules together.


does anyone know if nasa will be broadcasting live video from the cameras?

From nasaspaceflight.com:
Quote:
STS-119, which will carry up the final power generating array (S6) for the ISS, is likely to slip into 2009, should the expected delays be incurred by STS-125 and STS-126. However, information points to an interesting requirement being looked at, should Discovery's flight - currently manifested for December - be required to return home before offloading the payload.

'STS-119 is performance critical (S6 truss). Team determined that for contingency payload return, they were able to implement multi-stage de-orbit and gain 500 pounds of mass in the middeck, which helps Station.'
Does this mean that they lower the orbit using the OMS sometime before the de-orbit burn to reduce re-entry loads? Was this an issue for STS-97 with the P6 truss?

Does STS-123 burned at landing? If yes, what is the cause of fire at landing and its part, and why?

Clue: All astronauts survived and not in fire on the whole Space Shuttle Endeavour.
