They have never landed a Soyuz TMA spacecraft before. This soyuz-TMA-1 That will return the Expedition 6 crew this weekend will be the first time. Kind of makes me nervous.

-----from Encyclopedia Astronautica----

The Soyuz-TMA version was designed for use as a lifeboat for the International Space Station. It incorporated several changes to accomodate NASA requirements, including more latitude in the height and weight of the crew and improved parachute systems. The spacecraft also incorporates two new amber cockpit displays.

Soyuz-TMA 1 was a Russian automatic passenger craft. It carried the EP-4 visiting crew of three astronauts (two Russians and one Belgian) to automatically dock with the International Space Station (ISS). This was the first flight of the new Soyuz-TMA model.
