DRM2

  • 1.1m uTMA telescope, single channel, 2.4um cutoff

    • 6x2 H4RG(-10) @0.18”/pixel, ~0.50 sq. deg

  • Falcon9 LV to L2 orbital position

  • 6 position Filter wheel plus shutter:

    • 4 bandpass filters, ~1.0-2.4um; SN prism, uL wide filter,

  • Insertable GRS prism in 2nd wheel

    • Enables galaxy redshift survey

  • Aggressive schedule: project will push on 72 month ICE Probe baseline; use extended early phases to get H4RG(-10) to TRL6

    • WL must be goal/best effort

  • Selective redundancy

  • Phase E: 36 mo to be chosen from:

    • #1 15mo uL,

    • #2 6mo SN;

    • #3 15mo GO +gal plane

    • #4 12 mo imaging survey

    • #5 12 mo galaxy redshift survey

    • Will quantify return for extended mission out to 10yr

  • H4RG backup: H2RG with larger pixel scale [9x4 @0.21”/pixel]

  • Options:

    • IFU v. SN prism in wheel

      • Improve SN return & systematics
