This is the final entry in the Herschel Test Campaign journal series, which ran from August 2005 to February 2009. The journal covered the main activities during Herschel's extensive spacecraft and instrument test campaigns. It was followed by the Herschel Launch Campaign journal series, which ran from February 2009 until just before launch in May 2009 (see link in right-hand menu).Following the completion of the environmental test campaign at the end of 2008 the Herschel spacecraft has undergone a number of routine functional tests. These were completed last week and the spacecraft is now being prepared for transport to the launch site at Kourou.

On Thursday, 8 January 2009, the Herschel flight model spacecraft was lifted out of the Large Space Simulator at ESTEC, where it has successfully completed the last series of environmental tests. It is now completing a sequence of final functional tests before its departure for the launch site in Kourou.

This is the final entry in the Planck Test Campaign journal series, which ran from September 2005 to November 2008. The journal covered the main activities during Planck's extensive spacecraft and instrument test campaigns. It was followed by the Planck Launch Campaign journal series, which ran from February 2009 until just before launch in May 2009 (see link in right-hand menu).With the successful integration of the inner part of the flight model solar array to the Planck spacecraft on 25 November 2008 the project reaches another milestone.

In a series of dedicated tests the Planck flight model spacecraft has successfully demonstrated its ability to reach and maintain the extremely low operational temperatures required for its sophisticated instruments, down to 100 mK for the HFI detectors
Published: 17 November 2008
The Herschel spacecraft is now installed in the Large Space Simulator (LSS) at ESTEC ready for thermal balance and thermal vacuum tests. This is the final system test in the environmental test campaign series.

LISA Pathfinder has successfully completed a series of tests devised to characterise the shocks that the spacecraft will experience at launcher separation and when the science and propulsion modules separate upon reaching the operational orbit at L1.
Published: 10 November 2008
The LISA Pathfinder system level acoustic tests were performed on 9 and 10 September 2008 at the Large European Acoustic Facility (LEAF) at ESTEC, The Netherlands. The purpose of these tests was to confirm the load levels on the spacecraft units arising from random vibrations. Initial assessment of the test results indicates that the loads were as expected.
