Stakeholder dashboard

LEO NIR 1 m F/6 telescope concept

This site is the current stakeholder-facing index for the AAO mechanical and systems concept work. It is built directly from the generated engineering outputs in this repository, so the renders, reports, manufacturing package, and release gates all point back to the same released design snapshot.

Release checks

130/130

Gated checks currently passing in the release-state summary.

Stowed envelope

5.169 m

Diameter, with 6.321 m total height for the Ariane 6 packaged state.

Mass state

529.3 kg

Deployed physical mass, versus 557.4 kg in the stowed state.

Cold survival heater

2.35 W

Detector heater power currently required in the cold-case screening run.

Program decisions and current framing

1.0 m primary mirror, effective F/6.0 Cassegrain concept.
Passive thermal architecture with layered sunshields, V-groove shielding, and a dedicated cold radiator.
Released launcher baseline: ariane6.
Representative orbit model: 600 km sun-synchronous LEO at 97.8 deg inclination.
Sun keep-out envelope: 85 deg to 135 deg boresight-Sun angle.
Current repo state is screening-level engineering, not yet build-to-print or qualification-grade hardware.

The project is currently an engineering concept with strong reproducibility and release-truth checks, not yet a qualification-grade flight design.
The stakeholder site is rebuilt from repo outputs and should be redeployed after each logical chunk of engineering work.
Promotional renders come from Blender outputs that are manifest-signed into the release gate rather than being free-floating marketing images.
All published material on this page is meant to remain traceable back to the current design signature: 837095c6390ee9493e66d5de27386b78d597bbc34ba6eebbff3692c10685768f.
