Cool! I really need to go there. And with 300 km it's still closer than our capital...
Maybe I'll have some time to drive to Hemer in August. Soyuz TMA-13 is there since 2010 (I hope it's still there) and it's just one hour away.
I think the Soyuz TMA-13 is on permanent display.
While you're in the area, you should also pay a visit to the Museum in Sinsheim, which has both supersonic passenger jets, the Concorde and the Tupolev Tu-144 on display. Both museums are worth a visit (lots of space stuff, planes, cars and other cool stuff). They offer a joint admission ticket which is a bit cheaper and both have IMAX (3D or Dome) theaters which also show space related movies.

No, I'm not affiliated with the museums
