Cluster Mission updateM tt T l Matt Taylor THEMIS/ARTEMIS SWT /Fall 2011

• As mentioned last year, Cluster was granted an extension up to the end of 2014 This is subject to a mid term review on its technical capability in 2014. This is subject to a mid-term review on its technical capability in Summer 2012.

• Spacecraft went through lowest altitude since launch – 250 km spacecraft 22

• Current operations focus on continued auroral acceleration region activities and implementation of the Cluster guest investigator GI programme.

• Cluster team is preparing a proposal for a further extension to 2016 which Cluster team is preparing a proposal for a further extension to 2016 which will be submitted and considered in autumn 2012.

Cluster GI AO

AO called for new operations based on spacecraft separation and instrument mode to carry specific separation and instrument mode to carry specific science investigations.
