Only a few hours to go before they land? Have I got my dates right?

Is that UTC or GMT? There's a one hour difference between the two. I'll change it to Soyuz TMA-8 in the title too.

If NASA TV cover it as well as the last one, I'll bump this up to newsfeed for exposure.

Here you can see Zvezda is pointed towards the Earth, so the ISS is facing upwards! The Truss is parallel to the Earth. (Y-axis in the velocity vector?) The ISS and Soyuz are travelling in the same direction.

Ooops! I got my Soyuz-es mixed up  :o  GMT and UTC are virtually the same (UTC is more often used than GMT, which is a bit old-fashioned - Greenwich Mean Time at Wikipedia).

...Coverage ended a few minutes ago.

Anousheh wrote in her blog earlier that she was expecting a rough ride down.

Anyone have any info. on what the 'g' profile looks like for a nominal descent ?
