I didn't realize that so many changes were even envisioned.
Launch sites in the near futur :
From space.com:New launch base in Russia in Amur region due to enter service in 2018 : http://www.space.com/news/071121-new-russian-cosmodrome.html
From Aviation week nov 5 th 2007 issue page 30 : new launch base in China at Wenchang on the Hainan Island due in 2013 (no link to article)
From CSG (Centre Spatila Guyanais):Soyuz 2 due to be launched from Kourou next year (in french) : http://www.cnes.fr/web/4019-le-projet-soyouz.php
I didn't find a topic here on UMSF regarding launch sites. If there's one, thanks to move this post to the proper section. If not, we can may be discuss about past, actual and future launch sites of planet Earth.
