... Such a program would mainly utilize the Space Station capabilities for service and maintenance of co-orbiting platforms and free flyers. A further increase in the rate of growth of the current fiscal year 1985 NASA astrophysics budget at 3.7 percent per year would be required to pursue vigorously the new opportunities afforded by the Space Station for in-orbit assembly and deployment of large structures.

... SCIENTIFIC INSTRUMENTS TECHNOLOGY Interferometry The need for higher angular resolution, with a microarcsecond as a target, will require examination of the present and projected state of interferometry techniques from radio wavelengths to the ultraviolet. Technical needs of interferometry can be identified in three areas: structural technology, optical technology, and station keeping.

... The other consists of relatively compact arrays of curved glass plates to be assembled in modular arrays of telescopes. At energies below about ~ keV, narrow-bandwidth imaging telescopes operating at nearly normal incidence are being developed for solar applications; scared-up versions of these could be used for highsensitivity spectral line imaging of cosmic x-ray sources.

... If successful, the applications to future x-ray missions are very promising, from heterodyne interferometry to high-resolution spectroscopy.
