NASA announced a recently revised 1990 schedule for Space Shuttle launches that called for 9 flights instead of the previously announced 10. The reason behind the shuffling hinged on a three-week delay to launch the Hubble Telescope, originally planned for deployment March 26, because of an unsatisfactory leak check of the Space Shuttle's Solid Rocket Booster. This delay threatened the high-priority Ulysses mission scheduled for October 5. The mission had to be sent up within an 18-day time period in order to slingshot Jupiter and head back toward the sun, where it would achieve polar orbit around the star. The new agenda for Shuttle launches and their payloads is as follows: * Jan 9: Columbia; Navy communications satellite and retrieval of another.
Feb 22: Atlantis; classified military satellite.
Apr 18: Discovery; the Hubble Telescope.
May 9: Columbia; "astro" astronomy telescopes.
Jul 9: Atlantis; classified military cargo.
Aug 29: Columbia; a Spacelab life sciences module.
Oct 5: Discovery; the Ulysses probe.
Nov 1: Atlantis; Gamma Ray Observatory.
Dec 12: Columbia; a materials science laboratory.
A military mission carrying a variety of infrared sensors for the Strategic Defense Initiative was reassigned for 1992. NASA planned for 64 Space Shuttle flights and 30 expendable launch vehicle missions through September 1995. (UPI, Jan 29/90; W Times, Jan 30/90; NY Times, Feb 4/90; NASA Release 90-15)
