Engineers decided to change the segment and nozzle because they could not verify that a critical joint in the SRB nozzle had been properly leak checked at the factory. "The factory leak check in question is absolutely necessary to assure that the joint, or the O-ring on that joint, is not defective in any way," said Space Shuttle Director Robert Crippen. "In this case, we believe it was necessary to take a conservative approach and have decided to replace the joint with one that has an absolutely clean bill of health.

The mission is in the FY90 NASA budget now working its way through Congress. Launch is scheduled for April 1996 {on Titan IV/Centaur}. {Possible} asteroid flyby: asteroid 66 Maja in March 1997. 66 Maja is a 78-km-wide, C-type asteroid {thought to be similar to carbonaceous chondrites, if I have the terminology right.--SPW}. The flyby will be at a closest approach of 3,400 km. Earth flyby: June 8, 1988 {1998?--SPW} at 300 km altitude. Jupiter flyby: February 2000, {350 Jupiter radii}. Arrival at Saturn will come in December 2002. The Huygens probe will not be released until three months later and will enter Titan's atmosphere on March 17, 2003. The Cassini/Huygens mission will be a joint U.S.-European mission. It is the second Mariner Mark II (MM-II) spacecraft to be started by NASA (the first was the Comet Rendezvous/Asteroid Flyby for which investigations were selected in 1986). Other activities: Saturn orbit insertion: Dec. 6, 2002, after a flyby of the satellite Phoebe on the inbound leg. The initial orbit will have a 100-day period and be inclined 20 deg. to the equator. The Cassini orbiter will make a total of 60 orbits of Saturn over the next four years. Some 35 gravity assists at Titan, plus propulsive maneuvers, will "crank" the orbit from a period of 60 days down to 7 days and raise the inclination to 80 degrees. About 39 other "nontargeted satellite encounters," included Iapetus, Enceladus, and Dione, are planned as well. Other aspects of the orbit period are Saturn and ring occultations, high-inclination investigations, and ring-plane crossings. ASTRONAUTS NAMED FOR FIVE SPACE SHUTTLE MISSIONS - can891002.txt - 10/11/89 Astronaut crew assignments for five Space Shuttle missions in late 1990 and early 1991 include the first assignments from the astronaut class of 1987, the first U.S. Coast Guard astronaut to fly, the first European Space Agency (ESA) astronaut to be named as a mission specialist and the first black woman to be selected for space flight. ------------------ 5 ARTICLES BY TITLE ONLY ------------------------- HUBBLE SPACE TELESCOPE MOVES TOWARD LAUNCH - can891003.txt - 10/11/89 MAGELLAN SPECIAL REPORT - can891004.txt - 10/11/89 CRIPPEN TO HEAD SHUTTLE PROGRAM - can891005.txt - 10/23/89 GALILEO ON ITS WAY -- AT LAST - can891006.txt - 10/23/89 MAGELLAN WEEKLY STATUS - can891007.txt - 10/23/89 ----------------END OF CONDENSED CANOPUS----------------------------- This posting represents my own condensation of CANOPUS.

The address is: The British Interplanetary Society 27/29 South Lambeth Road London SW8 1SZ England I'm not sure how one goes about ordering specific back-issues of JBIS; the route that I'd pursue would be to write to the Society's Secretary, Mr. L. J. Carter, or telephone him at 01-735 3160 (fax 01-820 1504), and ask him; he's responsible for Society publications (although the issue in question was edited by Dr. W. McLaughlin of JPL). The BIS is one of the oldest and most respected of the various space societies around the world. For those interested in joining, I include the following information. The membership fee is L25 (i.e. 25 pounds sterling), or US$45 per year; if you are under 22 or over 65 years of age, the rate is L18 or US$32. Membership entitles you to receive one of either JBIS, or Spaceflight (the Society's space news magazine -- notable for providing coverage of a lot of international space news, the sort that AvWeek doesn't report very thoroughly). Further details may be obtained by writing to the above address. -- Kieran A.

One shuttle has gone up in how many launches? That's funny, no one told me when I missed a question or two one a test that I was "error prone" or "prone to making mistakes." Considering a recent comment about English-speakers, I'd appreciate proper use of the lanugage myself. It's always distressing to see a zero-risk type decide what is acceptable risk for all of us. Primarily, it demonstrates a fundamental misunderstanding of the risks inherent in travel by auto (my dad's an engineer in accident analysis. Better yet, ask your insurance agent) and more importantly it smacks of Yet-Another-Overly-Vocal-Minority. Unforunately, it is unlikely that people will stand up for their right to take a one-in-a-billion risk for the near-certain benefits of advanced spaceflight. And of course, no one is that unreasonable. We are all entirely welcome to take up a course that will take decades and cost _enormous_ sums of everyone's money - fissionables on the moon, since that doesn't inconvenience anyone with "undue risks."
