Mission Concept – Expected Content
11/25/2013
• 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.

Call for Mission Concept – Important Points
11/25/2013
• 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.
