4. Mission Concept – Expected Content
The mission Concept must address the science goals
Top level requirements:
High throughput optics: ≈ 2 m² collecting area)
High angular resolution: 5 arcsec
Wide field of view in the focal plane
Energy resolution: 2.5 eV
Technical Budget Envelopes:
Ariane 5 ECA: < 10 tons mass, 5.4 m diameter, 17 m height
< 75 Mbit/s downlink data rate (for Ka band, LagrangePoint L2)
Contribution from international partners (upon inter-agency agreements) is limited to 20% of the total mission envelope.

5. Call for Mission Concept – Important Points
ESA assessment of mission concept: Feasibility, technology readiness, international collaboration scheme (if applicable)
Announcement of Opportunity (early 2015 tbc): Consortium shall be selected. Teams or payload consortia shall not be pre-selected in the mission concept
The minimum request is to reach TRL 5/6 at mission adoption (2018/2019): Component and/or Breadboard Critical Function Verification in Relevant Environment
 Effective overall time for mission preparation including necessary technology developments: 2014 until 2019.
Critical Function: Mandatory function which requires specific technology verification
When TRL 5 is reached, the element feasibility can be considered as demonstrated, subject to scaling effects.
