•18 months needed to obtain the ITAR approval
•13 months delay in manufacturing due to technical issues (delivery expected in March)
The current schedule shows a camera delivery at end of Aug 2011

4– Launcher status
The foreseen launcher for Venµs is PSLV so far.
Unfortunately this scenario faces 2 issues • at the INDIAN government level• as Venµs would be the co-passenger, the risk exist to be injected in a non optimal orbit (i.e. 666 km – 3days instead of 720 km -2 days)
•Nevertheless, other scenarios exist, the main one being a launch with PLEIADES 2 on SOYOUZ
•Current engineering practice calls for a final launcher selection 2 years ahead of the foreseen launch date. In other words the launcher will be selected in 2010.
