Far Ultraviolet Explorer (FUSE) Observation Log

NASA's FUSE (Far Ultraviolet Spectroscopic Explorer) spacecraft provided spectra in the far-ultraviolet portion of the electromagnetic spectrum (the wavelength range from 905 - 1180 Angstroms, or 90.5 - 118 nm), with a high spectral resolution of about 20000 (one wavelength point each 5 pm). FUSE was funded by NASA as part of its Origins program, and was developed in collaboration with the space agencies of Canada and France. It was operated for NASA by the Johns Hopkins University. FUSE was launched into orbit aboard a Delta II rocket on June 24, 1999 for a nominal mission of three years of operations. This table contains the FUSE Observation Log up to May 8, 2007, as archived at CDS in summer 2007. FUSE was formally decommissioned on October 18, 2007, following the failure of the last control wheel on the spacecraft in July 2007. More information about the FUSE Project can be found at NASA's Optical and Ultraviolet Archive (MAST) at <a href="http://archive.stsci.edu/">http://archive.stsci.edu/</a>; and at the Johns Hopkins FUSE web site at <a href="http://fuse.pha.jhu.edu/">http://fuse.pha.jhu.edu/</a>;. This database table was updated by the HEASARC in March 2009, superceding the previous versions of May 2007, May 2004, March 2005, and April 2006. It is primarily based on the CDS table <B/fuse>, specifically, the files fuse.dat, refs.dat and proposal.dat, but also contains additional information on proposal titles and bibliographic codes obtained from the MAST FUSE Archive. The HEASARC plans to update the bibliographic metadata for this table on a monthly basis as and when new information from the latter source becomes available. This is a service provided by NASA HEASARC .
