Potential Concept 2 Options Dave Leisawitz NASA GSFC 1 1 1
Objective Maximize science capability within boundary conditions So, what are the boundary conditions? 14 June 2017 D. Leisawitz - STDT f2f #5 2 2 2
Options (for discussion) Change science scope and requirements Change aperture size Bigger? (very expensive, surely a large LV), or Smaller Spherical primary mirror, if it significantly reduces cost or risk? Fewer instruments? Fewer instrument operational modes? Telescope temperature a bit warmer? Quickly lose sub-mm sensitivity if much warmer Cost target? 14 June 2017 D. Leisawitz - STDT f2f #5 3 3 3
Keep in mind Lessons from Concept 1 will be brought to bear when we study Concept 2 Concept 1 cost is high relative to NASA funding wedge for the next large mission SPICA M5 mission concept is a third point in solution space we know something about science capability and science per $ for a 2.5 m cryogenic far- IR telescope The agenda allocates time for discussion of options, and process for deciding on the BCs. 14 June 2017 D. Leisawitz - STDT f2f #5 4 4 4
