Announcement of Opportunity for the JUICE Payload

Announcement of Opportunity for the JUICE Payload

26 June 2012

Through this Announcement of Opportunity the European Space Agency (ESA) solicits proposals for the provision of the scientific payload on board the JUICE spacecraft. The deadline for submission of proposals is 15 October 2012, 12:00 CEST (noon).

Update - 6 September 2012Proposal submission form now available.

Update - 16 July 2012: Briefing meeting presentations now available (see below).

Update - 11 July 2012: Additional information on the briefing meeting has been added (see below).

JUICE (JUpiter ICy moons Explorer) was selected in May 2012, by the Science Programme Committee (SPC) as the L1 mission in the Cosmic Vision programme, with a foreseen launch date in 2022. The JUICE spacecraft will provide a thorough investigation of the Jupiter system in all its complexity with emphasis on the three ocean-bearing Galilean satellites, and their potential habitability. JUICE has been tailored to observe all the main components of the Jupiter system and untangle their complex interactions. 

The JUICE spacecraft constitutes the European element of a coordinated program to Jupiter and its icy moons, which also foresees a Russian Ganymede lander, to be operated by Russia in coordination with JUICE. The joint program would allow a complete characterization of Ganymede, above and beyond what could be achieved with either element alone.

This Announcement of Opportunity (AO) for the provision of the scientific payload on board the JUICE spacecraft is open to scientists from the Member States of ESA and other communities with which reciprocity or specific agreements exist (such as USA, Russia, Japan). An agreement has already been established with NASA as a minor payload contributor. An agreement with Russia concerning payload provision for JUICE spacecraft and the Russian Ganymede lander is under discussion.

Furthermore, discussions with Russia on the possible evolution of the joint program profile are on-going. ESA reserves the right to amend or modify the present AO as needed, based on the outcome of such discussions, at any time.

With this AO it is intended to select the Instrument Consortia for the provision of the scientific payload on board the JUICE spacecraft. Instruments that address the JUICE science goals as described in the Assessment Study Report (Yellow Book) and in the Scientific Requirements Document will be given priority, although proposals addressing other science goals are not excluded a priori. The proposals shall include all Consortia elements necessary for the implementation phase, clearly defining tasks and level of commitment.

NOTE: Only Instrument Consortia that will submit a Letter of Intent by 6 July 2012, 12:00 CEST (noon), will be allowed to submit a Proposal.

Briefing Meeting

A briefing meeting intended to clarify technical and/or programmatic issues will be held at ESTEC, Noordwijk, The Netherlands, on 13 July 2012, from 11:00 to 15:00 hrs (max) in room Newton.
In preparation for this meeting, written questions should be sent by 6 July 2012, addressed to:

Attendance of the briefing meeting: Candidate Principal Investigators (PI)s of the Instrument Consortia shall indicate their intention to attend upon submission of their LOI. Other attendees shall inform ESA of their interest to attend by email:

Additional information (Update - 11 July 2012)

Proposals Information Package

The Proposal Information Package (PIP) for this AO is available from the "documentation" section in the right-hand menu. The PIP is provided as a zip file and contains, in addition to the AO document [ESA/SRE(2012)4], the following documents:

  • Science Requirements Document (Sci-RD)
  • Model Payload Definition Document (MPDD)
  • Science Management Plan (SMP)
  • JUICE Assessment Study Report (Yellow Book)
  • Experiment Interface Document-Part A (EID-A)
  • Proposal Template
  • Experiment Interface Document-Part B (EID-B) template JUI-EST-XXX-EID-00X
  • Environment specification
  • Planetary Protection Requirements
  • CREMA (Consolidated Report on the Mission Analysis)
  • End-to-end trajectory ephemeris files
  • Tailoring of ECSS-E-ST-20-06C (Charging) for JUICE
  • Technical notes on environment properties and radiation transport simulations
  • JUICE project documentation and configuration management procedure
  • Science Operations Assumptions Document (SOAD)

A summary of the JUICE mission overview, instrument selection procedure and a recapitulation of the investigators' duties and responsibilities can be found in the SMP.

The EID-A defines the technical and programmatic requirements (including management and control procedures), and specifies in detail the interface and planning applicable to the instruments.

Letter of Intent (LOI) submission

Prospective Consortia are required to submit a Letter of Intent (LOI) stating their intention to submit a proposal in response to the present AO.

LOI submission deadline: 6 July 2012, 12:00 CEST (noon)

The LOI shall be submitted by the candidate Principal Investigator of the Instrument Consortium in electronic form, in PDF format, using the online submission form that can be accessed below or from the right-hand menu (the form opens in a new window).
