Featured speakers for the ceremony include NASA's Associate Ad- ministrator for Space Flight Dr. William B. Lenoir, KSC Director Forrest S. McCartney, Space Station Freedom Director Richard Kohrs, KSC Space Station Project Office Manager Dick Lyon and KSC Director of Engineering Development Walt Murphy. The ceremony will take place at the construction site in the KSC Industrial Area, just east of the Operations & Checkout Building. The SSPF will be a KSC-operated facility occupied by about 1,000 NASA and contractor employees. The three-story SSPF will include communications and electrical control areas, laboratories, logis- tics staging areas, operational control rooms, office areas and a cafeteria. The SSPF will have over 63,000 square feet of dedi- cated payload processing space, which includes a high bay and in- termediate bay. A 5,000-square-foot airlock will be adjacent to the primary processing area. Both the airlock and processing area will be 100,000 parts-per-million-rated clean rooms. The SSPF is the biggest new construction facility undertaken at KSC since the Apollo era. The building was designed by Jacobs Engineering Group, Inc. of Lakeland, Fla. and will be constructed by Metric Constructors, Inc. of Tampa, Fla. The building's cost is $56,215,000. News media wishing to cover the ceremony should be at the KSC News Center by 9:15 a.m. Tuesday, March 26, for transportation to the ceremony site. Media representatives with permanent creden- tials may drive directly to the News Center. Those who require access badges should contact the News Center at 407/867-2468 to arrange access. # # # # # ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |___ M/S 301-355 | Change is constant. /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | |_____|/ |_|/ |_____|/ | ------------------------------ Date: 15 Mar 91 03:14:55 GMT From: usc!elroy.jpl.nasa.gov!jato!mars.jpl.nasa.gov!baalke@apple.com (Ron Baalke) Subject: Magellan Update - 03/14/91 MAGELLAN STATUS REPORT March 14, 1991 The Magellan spacecraft is performing nominally. All of the STARCALS (star calibrations) and DESATS (desaturations) yesterday were successful. Last night a command was sent to the spacecraft to switch from Transmitter B to A. This appears to have cleared up the X-band communications problem. This morning a good signal-to-noise ratio of 8.4 on the high rate data was observed. During the reconfiguration of AACS (Attitude and Articulation Control Subsystem) Memory B yesterday, some alarms were noted when controllers reset the off-line power flag. Specifically, the heartbeat loss counter was incremented and there was an indication of an attempt by the AACS computer to access write-protected memory. So the spacecraft controllers decided to put the off-line power flag to its prior setting and delay the reactivation of AACS Memory B until the reason for the alarms can be analyzed. No spacecraft commanding is planned for today. Tomorrow, the upload of tweak P1075, with the updates of the radar control parameter and mapping quaternion files is planned. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |___ M/S 301-355 | Change is constant. /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | |_____|/ |_|/ |_____|/ | ------------------------------ Date: 11 Mar 91 23:29:30 GMT From: pasteur!dog.ee.lbl.gov!hellgate.utah.edu!caen!sdd.hp.com!elroy.jpl.nasa.gov!freedom!xanth!mcdowell@ucbvax.Berkeley.EDU (Jonathan McDowell) Subject: Jonathan's Space Report, Mar 11 Jonathan's Space Report Mar 11 1991 (no.67) ---------------------------------------------------- Launch of STS-37/Atlantis and the Gamma Ray Observatory remains due for early April. Viktor Afanas'ev and Musa Manarov continue in orbit aboard the Mir/Kvant/Kvant-2/Kristall/Soyuz TM-11/Progress M-6 complex. An Ariane 4 rocket successfully orbited two satellites on Mar 2. Astra 1B is a TV broadcasting satellite owned by the Luxembourg based company SES (Societe Europeene des Satellites). MOP (Meteosat Operational Programme) 2 is a European geostationary weather satellite and will probably be renamed Meteosat 5 now that it is in orbit. It is operated by ESA for the EUMETSAT (European Meteorological Satellite Organization). The Arianespace SA Ariane rocket is launched from the ESA base at Kourou in Guyane; the third stage enters an elliptical geostationary transfer orbit (GTO) with a perigee of a few hundred km and an apogee of 36000 km. The two satellites separate from the third stage, and then once at apogee ignite their internal rocket motors (a European MAGE rocket for Meteosat, and probably a Thiokol Star 30 for Astra), putting them in approximately circular equatorial 24 hour orbits. Small thrusters are used to put the satellites in near exact stationary orbits once they have drifted to the right longitude. The 27th Raduga geostationary communications satellite was launched on Feb 28 by 4-stage Proton from Baykonur. Raduga is a C-band comsat for relay of telephone and TV transmissions, first launched in 1975 for the Soviet Ministry of Communications. A Delta II 6925 launch vehicle placed the INMARSAT II F-2 satellite in geostationary transfer orbit on Mar 10. INMARSAT is the International Maritime Satellite Organization. The INMARSAT satellites provide L-band mobile communications links for ships, aircraft and vehicles. The first INMARSAT II was launched last year. There were no INMARSAT I satellites; previously INMARSAT leased the MARECS satellites from ESA, the MARISAT satellites from Comsat General Corp., and the MCS transponders on the INTELSAT VA satellites. ___________________________________ |Current STS status: | |Orbiters | | | |OV-102 Columbia OPF Bay 1 | |OV-103 Discovery VAB Bay 3 | |OV-104 Atlantis VAB Bay 3 | | | |ML/ET/SRB stacks | | | |ML1/STS-37/ET/OV-104 VAB Bay 1 | |ML2/STS-39/ET/OV-103 VAB Bay 3 | |ML3/STS-40 Outside VAB| ----------------------------------- 10 years ago: 12 Mar 1981 Vladimir Kovalyonok and Viktor Savinykh reached orbit in Soyuz T-4.

Its transmitter operated for 8 years. 30 years ago: 9 Mar 1961. Korabl'-Sputnik-4 was launched by Vostok rocket from Baykonur on one of the final unpiloted test flights of the Vostok spaceship. The cabin, containing guinea pigs, mice, insects, and a dog called Chernushka, was recovered after one orbit. (c) 1991 Jonathan McDowell.

Especially when you think about the peak heating and peak aero loads for a projectile thrown from the surface with enough energy to reach orbit. Simply put, it would burn up before it got there. Railguns would be great in a vacuum, though, at least in principle. Now all we need is the ability to get up there and use them....

If there is, I would appreciate it greatly if you could E-mail them to me at cordolf@athena.mit.edu. The delta-vees I'm looking for specifically are: a) Direct escape from LEO to outside the solar system b) Escape from the solar system from LEO using a flyby of Jupiter c) Collision trajectory with the sun, direct from LEO d) Collision with sun from LEO, using a Jupiter flyby There were several other suggestions for trajectories to calculate, such as Oberth escapes from the solar system using a burn at Earth and another at perihelion, (possibly including a Jupiter flyby) but these were decided against by the group. If anyone has any ideas about means of getting rid of nuclear waste, or orbit information (delta-vee's, optimum trajectores, etc) that they think I might find useful, I would greatly appreciate it if they could please E-mail them to me soon.
