Madrid is close to the 0 meridian. Canberra is about 150 degrees east of that. Goldstone is about 90 degrees east of Canberra. It looks like the biggest gap is between Madrid and Canberra. Maybe they could put one is, say, India? (75 deg east longitude). Or how about Diego Garcia? I seem to remember that there was a station in Madagascar (45 deg E) for the Apollo flights. -- Perry G.

Discovery and Ulysses left the launch pad at NASA's Kennedy Space Center, Florida, at 7:47:15 a.m. Eastern Daylight Time (4:47:15 a.m. Pacific Daylight Time (PDT), or 11:47:15 Universal Time (UTC)). Ulysses and its stack of upper stage engines were released from Discovery's payload bay at 17:48 UTC (10:48 a.m. PDT) when the shuttle was over the Pacific Ocean between Guam and Hawaii at the beginning of its fifth orbit around Earth. The first of two stages of an Inertial Upper Stage (IUS) booster attached to Ulysses fired at 18:53 UTC (11:53 a.m. PDT) over the Indian Ocean near Madagascar, followed by the IUS second-stage firing at 18:57 UTC (11:57 a.m. PDT). A Payload Assist Module (PAM-S) attached to Ulysses then ignited at 19:01 UTC (12:01 p.m. PDT), with Ulysses separating from the PAM-S at 19:11 UTC (12:11 p.m. PDT). At the time of PAM-S burnout Ulysses's geocentric velocity was 34,130 miles per hour, the fastest departure speed of any human-made craft leaving Earth. The signal from Ulysses's medium-gain antenna was acquired by the NASA/JPL Deep Space Network Station near Canberra, Australia, at 19:17 UTC (12:17 p.m. PDT) by the station's 26-meter-diameter antenna. On Sunday, October 7, Ulysses deployed its radial boom, a 5.6-meter (18.2-foot) beam carrying a number of sensors for the craft's science instruments. This slowed the spacecraft's spin rate from 6.8 revolutions per minute (rpm) to 4.7 rpm, as planned. The next significant event scheduled will be the pointing of Ulysses's high-gain antenna dish toward Earth on Thursday through Saturday, October 11-13. A trajectory correction maneuver is planned Monday and Tuesday, October 15-16, to fine-tune Ulysses's initial flight path toward the planet Jupiter. Following that operation, each of the craft's nine instruments will be turned on over a period spanning about 6-1/2 weeks. After encountering Jupiter in February 1992, Ulysses will orbit the Sun at about a right angle to the ecliptic, the plane in which the Earth and other planets orbit the Sun. The five-year mission to study the Sun's poles and interstellar space beyond the poles is conducted jointly by NASA/JPL and the European Space Agency. ___ _____ ___ /_ /| /____/ \ /_ /| | | | | __ \ /| | | | Ron Baalke | baalke@mars.jpl.nasa.gov ___| | | | |__) |/ | | |___ Jet Propulsion Lab | baalke@jems.jpl.nasa.gov /___| | | | ___/ | |/__ /| M/S 301-355 | |_____|/ |_|/ |_____|/ Pasadena, CA 91109 | ------------------------------ Date: 12 Oct 90 23:37:47 GMT From: trident.arc.nasa.gov!yee@ames.arc.nasa.gov (Peter E.

The Energia strap-ons are also the first stage of the Zenit booster. On page 13 of the 12 October Boston Globe is a small story headlined "Soviet rocket explodes at liftoff; syp satellite believed on board." Apparently a Zenit rocket exploded shortly after liftoff on 4 October (33rd anniversary of Sputnik 1!), destroying its payload and nearly destroying one of two Zenit launch pads at Baikonur. Further Zenit launches have been put on hold pending an accident investigation, according to Nikolai Semyonov, head of Glavkosmos' international department. (The article also called the Zenit the Soviet Union's "most advanced booster rocket", though Energia is arguably more advanced since it incorporates the same technology plus the only use of liquid hydrogen to fuel a Soviet booster.) -- Chris Jones clj@ksr.com {world,uunet,harvard}!ksr!clj ------------------------------ Date: 10 Oct 90 15:30:14 GMT From: mvb.saic.com!ncr-sd!ncrlnk!ncr-mpd!Mike.McManus@ucsd.edu (Mike McManus) Subject: Man-rated SRBs (was Re: Junk the shuttle?)

I've heard this stated on the net a number of times, but don't really understand why this is so. What is the problem with SRBs? Safety? Reliability?
