On January 12, 2011, Space Adventures and the Russian Federal Space Agency announced that orbital space tourism would resume in 2013 with the increase of manned Soyuz launches to the ISS from four to five per year.
However, this has not materialized, and the current preferred option, instead of producing an additional Soyuz, would be to extend the duration of an ISS Expedition to one year.
