A future NASA mission to launch one, or possibly two, 25-m radio telescopes to observe space in conjunction with numerous ground radio telescopes using very long-baseline interferometry. The satellite for the ARISE mission, tentatively scheduled for 2008, will have a highly elliptical Earth orbit. It will look at super-massive black holes and galactic nuclei to study how galaxies evolve and how matter reacts under great pressures. Scientists believe ARISE will produce images of black holes that are 5 000 times better than those from the Hubble Space Telescope.
