Discovery One -- Lander

Carrying platform approach to a lander.

  • Rectangular-shaped carrying platform
    Few or no control surfaces.
    Flyweels/gyros are used in place of control surfaces.
    Retro rockets -- fixed or on a swivel.
    Series of parachutes on top of the upper flat surface as fail-safe.
    Ultra wide fuselage -- essentially an air foil, wider than HTV-3X or BlackSwift.
    All or most of the frame in titanium or carbon (10x stronger than steel).
    Stripped down interior to reduce weight.
    Non pressurized -- passengers wear their space suits.
    Swivel seats for vertical re-entry.
    Second generation have aerospikes for takeoff -- maybe in 40 yers.

Discovery One -- Cost Study

Approximate costs of materials, manpower, launches, etc.

  • Material costs -- Mostly already R&D(ed) materials
    Titanium Grade1 ($US25000/MT)
    Titanium Alloy ($US8000/MT)
    Titanium Grade5 ($US6000/MT)
    High-Grade Ceramic ($US2000/MT)
    High-Grade Poly-Amide ($US2500/MT)
    Oxygen soaking material ($US10000/MT)

    3D-Camera or multiple cameras for increased depth of field
    Transparent aluminum casing for camera lenses
    Manipulator arms plus tooling for Sphere assembly
    Fly-by-Wire controls and automated pilot mode
    Peroxide for propulsion, or better alternative.
