  3. 1- Camera status DETECTORS ASSEMBLY THERMAL CONTROL SHIELD SUN SHIELD BEZEL TUBE CEU CORRECTION LENSES SMA PMA Camera longitudinal section VENµS users meeting – Jan 2010

  4. 1- Camera status Tube equipped with both mirrors VENµS users meeting – Jan 2010

  5. 1- Camera status Correction lens assembly VENµS users meeting – Jan 2010

  6. 1- Camera status Thermal control shield (external cylinder) VENµS users meeting – Jan 2010

  7. 1- Camera status Blocking Filter 2.0 mm ~ 1.4 mm Narrow-band Filters 8.0 mm 10 mm Camera status synthesis • BARR filters= the weakest link of the chain, so far... • 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 VENµS users meeting – Jan 2010

  8. 2– Bus status - Mass: 250kg - Power: 800w - Overall stowed dim: 1.6x1.2 m - 2xSTR - 2 X-band - 1xIHET redunded, 16 Kg Xenon - 4x1N redunded thrusters, 7 Kg hydrazine VENµS users meeting – Jan 2010

  9. 2– Bus status VENµS users meeting – Jan 2010

  10. 2– Bus status VENµS users meeting – Jan 2010

  11. 2– Bus status VENµS users meeting – Jan 2010

  12. 2– Bus status Bus status synthesis • Base plate to be delivered this quarter (from RAFAEL to IAI) • Other parts of the bus are stored and readyfor final bus assembly (solar pannel, satellites pannels - 6 of them, and all bus internal subsystems) VENµS users meeting – Jan 2010

  13. 3– Ground segment status Scientific mission FRANCE Satellite command & control and technological mission ISRAEL Ready end of 2010 Ready end of 2010 VENµS users meeting – Jan 2010

  14. 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. VENµS users meeting – Jan 2010
