2nd Announcement of Opportunity for Cluster Guest Investigators
17 February 2014This Announcement of Opportunity solicits special operation proposals for participation in the Guest Investigator (GI) Programme of the Cluster extended mission from the European Space Agency (ESA). The aim of the GI Programme is to open future spacecraft science operations to the scientific community. Investigations are solicited which identify compelling utilization of the Cluster spacecraft payload for scientific study, for the period 2015-2016. The deadline for proposal submissions is 2 June 2014, 23:59 CEST.

Updated 7 May 2014: The proposal submission form is now available. See below.
Following the successful Cluster Guest Investigator (GI) Announcement of Opportunity in 2010, and the execution of the last GI operations in December 2013, ESA is issuing this second Announcement of Opportunity (AO). The AO solicits special operation proposals for participation in the Guest Investigator Programme of the Cluster extended mission, for the period 2015-2016.
It should be noted that the Cluster mission extension for 2015-2016 is subject to confirmation by ESA's Science Programme Committee in November 2014.
This AO is open to the worldwide scientific community (i.e. not limited to ESA member states).
Proposals to exploit Cluster data along with other satellites data (e.g. THEMIS, Van Allen Probes, SWARM, MMS), or proposals for theoretical and/or modelling studies focused on the goals and objectives of the mission, are encouraged.
Investigators are encouraged to propose the acquisition of data from more than one instrument. Inter-spacecraft separation can be changed but is limited to phasing manoeuvres due to limited available fuel.
Proposers are strongly encouraged to examine the information available via the documentation section of the Cluster Science Archive (http://rssd.esa.int/csa/), which also accompanies this AO as part of the Proposal Information Package (PIP). In particular proposers are directed towards the instrument user guides, to obtain information on spacecraft payload specifications. In addition, proposers may contact the Cluster Project Scientist, Philippe Escoubet, and also instrument PIs directly for further information on instrument limitations and spacecraft limitations that may be pertinent to their proposal (see the AO documentation for contact details).
Full details of this AO and the guidelines for the Letters of Intent and Proposals in response to this AO can be found in the Cluster AO document, which is included in the documentation package for this AO.
