摘要：

The Far Ultraviolet Spectroscopic Explorer (FUSE) satellite will make high spectral resolving power (lambda/Delta lambda = 20,000 - 30,000) measurements of astrophysical objects in the 905-1187 Angstrom wavelength region from low-earth orbit. Its high effective area (20 - 70 cm(2)) and low background will permit observations of solar system, galactic, and extragalactic targets that have been too faint for previous instruments at this high resolution. Integration and test of the FUSE instrument is currently underway in preparation for launch in late 1998. We describe the current status of the FUSE satellite, including details of the optical and mechanical measurements made during component and subsystem-level testing. In addition, we make an estimate of instrument on-orbit performance from data obtained during instrument integration and test.
