The RD-170 engines on the Energia (the engines of the strap-ons) are designed to be reused up to 10 times. They have never been reused, I believe (it's also the engine on the first stage of the Tsyklon launcher). "A parachute recovery system is under design for the current Energia strap-on boosters, but Gubanov [Energia's chief designer] was not optimistic the system would be cost-effective." The engines on the core of the Energia are not reusable, and the core is not designed to be recovered. -- Chris Jones clj@ksr.com {world,uunet,harvard}!ksr!clj ------------------------------ Date: 30 Nov 90 18:24:20 GMT From: uvaarpa!murdoch!murdoch.acc.virginia.edu!dwells@mcnc.org (Don Wells) Subject: HST images via anonFTP and SPAN/HEPnet In article <2053@stsci.EDU> on sci.space, subject "Re: HST images", jay@stsci.EDU (Jay Travisano) writes: JT> There have been a number of requests for Internet access to HST images.

The subsystem tests will be performed first which includes testing the attitude control system, propulsion system, electrical system, and thermal control system. This will be followed by testing each of the four science instruments, the Burst and Transient Source Experiment (BATSE), the Imaging Compton Telescope (COMPTEL), the Energetic Gamma Ray Experiment Telescope (EGRET), and the Oriented Scintillation Spectrometer Experiment (OSSE). On the EGRET, neon gas used by the experiment during previous tests is being purged, and the flight load of neon is scheduled to be loaded aboard next week. The high gain antenna was installed on Nov 14 and the functional testing has been completed. At this time, GRO is scheduled to be moved to the Vertical Processing Facility on Feb. 4. ------------------------------ Date: 30 Nov 90 17:39:31 GMT From: hub.ucsb.edu!ucsbuxa!3001crad@ucsd.edu (Charles Frank Radley) Subject: Re: Total Solar Eclipses In article <17838@hydra.gatech.EDU> ccoprmd@prism.gatech.EDU (Matthew DeLuca) writes: >In article <1990Nov29.221429.25825@zoo.toronto.edu> henry@zoo.toronto.edu (Henry Spencer) writes: >>Beware that accommodations and such are already *very* heavily booked. >>Don't just go, in hopes that you can find a place to stay; there won't >>be any vacancies. >I don't know about South America, but July in Baja California is pretty >nice; just pitch a tent! >-- >Matthew DeLuca >Georgia Institute of Technology Do not meddle in the affairs of wizards, >Office of Information Technology for they are subtle, and quick to anger. >Internet: ccoprmd@prism.gatech.edu Hewnry is right.

File pub/SPACE/7.4.4 on ames.arc.nasa.gov says, in part: In Russia, Konstantin Tsiolkovsky left a legacy of significant writing in the field of rocketry. Although Tsiolkovsky did not construct any working rockets, his numerous essays and books helped point the way to practical and successful space travel. Tsiolkovsky spent most of his life as an unknown mathematics teacher in the Russian provinces, where he made some pioneering studies in liquid chemical rocket concepts and recommended liquid oxygen and liquid hydrogen as the optimum propellants. In the 1920s, Tsiolkovsky analyzed and mathematically formulated the technique of staging vehicles to reach escape velocities from Earth. -- Chris Jones clj@ksr.com {world,uunet,harvard}!ksr!clj ------------------------------ Date: 1 Dec 90 00:36:15 GMT From: usc!cs.utexas.edu!uwm.edu!ux1.cso.uiuc.edu!uxa.cso.uiuc.edu!sfn20715@ucsd.edu (Steve "il-Manhous" Norton) Subject: Enough for a big party...

The commands were transmitted on November 22 and 23. However the receiver switch did not occur. The sequences will be repeated as often as possible. On November 26, the high gain main feed was offset for 1 hour, and AGC (Automatic Gain Control) data was collected. The data are being analyzed to look for some periodicity, indicating the spacecraft spin rate. It is hoped that these data, in conjunction with the Sun pulse, will generate a spacecraft attitude. CONSCAN measurements have been unable to be performed with the medium gain antenna. A scheduled 70 meter Goldstone track on November 27 was cancelled due to a cracked subreflector brace. A precession maneuver is scheduled for November 30. Nine quadrature pulses will be fired. This maneuver is being executed without accurate knowledge of the previous attitude because of the inability to perform CONSCAN measurements with the medium gain antenna. ___ _____ ___ /_ /| /____/ \ /_ /| | | | | __ \ /| | | | Ron Baalke | baalke@mars.jpl.nasa.gov ___| | | | |__) |/ | | |___ Jet Propulsion Lab | baalke@jems.jpl.nasa.gov /___| | | | ___/ | |/__ /| M/S 301-355 | |_____|/ |_|/ |_____|/ Pasadena, CA 91109 | ------------------------------ Date: 30 Nov 90 04:44:03 GMT From: news-server.csri.toronto.edu!utgpu!utzoo!henry@rutgers.edu (Henry Spencer) Subject: Re: Astro-2 In article <1176@inews.intel.com> sstrazdu@hopi.intel.com (Stephen Strazdus) writes: >Is there an Astro-2 flight in the works for the Space Shuttle? ...

Yee) Subject: Review of U.S./Japan space cooperation (Forwarded) Debra J. Rahn Headquarters, Washington, D.C. November 29, 1990 (Phone: 202/453-8455) RELEASE: 90-156 REVIEW OF U.S./JAPAN SPACE COOPERATION NASA and the Space Activities Commission of Japan (SAC) held a series of meetings in Arlington, Va., during the week of Nov. 26, culminating in the fourth meeting of the NASA/SAC Cooperative Space Activities Planning Group on Nov. 29. The Cooperative Space Activities Planning Group meets annually to review ongoing space cooperation between the U.S. and Japan. Discussions focused on a number of collaborative projects in the fields of astrophysics, solar system science, microgravity science, life science and Earth observation. The meeting was co- chaired by Dr. Lennard Fisk, NASA Associate Administrator for Space Science and Applications, and Mr. Katsuhisa Ida, Director- General, Research and Development Bureau, Science and Technology Agency (STA) of Japan. During the week, Ida met with senior NASA officials, including Richard H. Truly, NASA Administrator. During these meetings, the following cooperative proposals were discussed: o NASA Associate Administrator for Space Flight Dr. William B. Lenoir affirmed to Ida that two Japanese candidates are invited to join the next NASA Mission Specialist training class, beginning in July 1992. The Japanese Mission Specialist candidates will participate in training on the same basis as U.S. Mission Specialist candidates at NASA's Johnson Space Center, Houston. It is NASA's intent to offer a Space Shuttle flight assignment to one or both of the Japanese Mission Specialist candidates in the years following the successful completion of the training program. o NASA and STA are actively reviewing options for flying Japanese Experiment Module (JEM) hardware on a Space Shuttle mission in the mid-1990s. The JEM is Japan's contribution to the Space Station Freedom program. The purpose of such a Shuttle flight would be to demonstrate in space a key element of the JEM. o NASA also offered Japan an opportunity to send Japanese engineers to work and train in the Mission Operations Directorate at the Johnson Space Center during mission preparation and operations activities for the Spacelab-J mission. This will enable Japan to obtain additional flight operations experience prior to the Space Station era. The next meeting of the Cooperative Space Activities Planning Group will be next fall in Japan. ------------------------------ End of SPACE Digest V12 #614 *******************
