The future of x-ray astronomy depends upon development of x-ray telescopes with larger aperture areas (≈ 3 m2) and
fine angular resolution (≈ 1″). Combined with the special requirements of nested grazing-incidence optics, the mass and
envelope constraints of space-borne telescopes render such advances technologically and programmatically challenging.
Achieving this goal will require precision fabrication, alignment, mounting, and assembly of large areas (≈ 600 m2) of
lightweight (≈ 1 kg/m2 areal density) high-quality mirrors at an acceptable cost (≈ 1 M$/m2 of mirror surface area). This
paper reviews relevant technological and programmatic issues, as well as possible approaches for addressing these
issues—including active (in-space adjustable) alignment and figure correction.
