After a secret transcontinental flight, NASA's Hubble Space Telescope has arrived at the Kennedy Space Center at Cape Canaveral, Fla., where it will be tested in preparation for a March 26, 1990, launch aboard the space shuttle Discovery.The telescope was gingerly transferred from a Lockheed plant in California, where it was assembled, to Florida on an Air Force C‐5 transport plane. The details of the move were not made public because the Air Force moves around top‐secret spy satellites similar to the HST in much the same way as it did the NASA telescope.
