I live in the Los Angeles area and am going to try to watch the Delta 2 launch from Vandenberg AFB of the first 3 Iridium satellites. Actually, I already tried twice but the launch was scrubbed each time. Now, I heard one report that it will not be re-scheduled until after the cause of the Delta 2 explosion Jan. 17 at Canaveral AFB is known and understood. The Iridium project will eventually be a 66 low earth orbit constellation requiring many launches hopefully many from Vandenberg. Originally the design was to have been 77 satellites and Iridium is the 77th element in the periodic table of elements, thus the name. Then the plan changed to 66 satellites but they decided to stick with the name. Iridium is to be a totally worldwide (even the arctic and antarctica regions) voice, fax, data, paging system supporting hand-held receivers. Does anyone have a notion as to the potential visibility of these satellites once in orbit? In browsing the web, I saw a small image and it looks like a dark color scheme so that doesn't look too favorable for the visual satellite observer. Or am I wrong? Also, I'm attempting to be an avid, gung-ho, Vandenberg space launch observer. Does anyone know if there are radio frequencies that can be monitored to help me keep on top of exactly when launches will occur? Are private and commercial pilots given a "heads-up (or heads-down)" on radio when a launch is about to happen? I have some web pages bookmarked and some hotline phone numbers but I'm looking for more ways to be on top of launch situations. Incidentally, I saw the Titan 4 launch Dec. 20. Because I didn't leave early enough and because of darned freeway traffic, I was still 10 min. outside of Lompoc when I saw through my windshield the rocket streaking up. With a mixture of excitement and frustration (because I wasn't closer), I immediately pulled over and looked at it with my binoculars and the naked eye and saw a couple of boosters separate from it. It launched at 10:04 AM PST and Ted Molzcan had predicted as I remember 10:07 plus or minus 15 min. I was amazed at his accuracy because the launch window was 3.5 hrs. long. I think there is supposed to be another Titan 4 in April. My "heads-up" on the Dec. Titan 4 launch was postings in SeeSat. Please keep up any space launch postings. Before last month's Titan 4, my previous launch experience had been the Apollo 8 Saturn V launch in Dec. 1968. We lived in Florida about 2 or 3 hrs. drive away, and as I remember, pretty much on a whim, my father and I decided to drive down and watch it. We watched it from a motel parking lot in Titusville which I think was about 15 mi. away. What a sight and sound! I'm glad we got that whim. On visits to Florida, several times I've tried to coordinate my trips with Space Shuttle launches, but in each case, it was either delayed or scrubbed so I've never managed to see one. One time, I was there with binoculars trained on the pad and it got scrubbed 30 sec. before launch. It launched some days later but I was back in California. Sorry if I've gotten off-topic or rambled on too much but I have a tendency to do that. Jake Rees Burbank, California
