The book details fuels and oxidizers far more exotic than those in common use: Boron compounds and beryllium and lithium and suchlike as fuels (including such unlikely compounds as mercaptans and lemon oil), burned with fluorine, ozone, and exotic oxidizers such as NF3, ClF3, ClF5, and N2F4. Clark was in charge of the chemistry end of much of the original research into storable liquid propellants for military missles, and has written his experiences down in an eminently readable and enjoyable account. I too wish that I had a copy of the book. The copy I read was in a University library. I believe that the main UCLA library has a copy. I wrote to Clark several years ago about some of the contents of the book - he related to me that he thought that the book had been a success worth the effort. He was particular proud that the publisher had no more copies left. The last dozen or so copies were purchased as a lot by the Soviet embassy to the U.S. ! -- Bruce Dunn Vancouver, Canada a752@mindlink.UUCP ------------------------------ Date: Mon, 28 Jan 91 13:31:57 AST From: Richard Langley Subject: Navstar GPS Satellite Develops Problem According to a report in the 14 January 1991 issue of Aviation Week & Space Technology, the latest Navstar GPS satellite to be launched (II-10, PRN 23) has experienced a significant problem with its solar panels. The problem developed on 12 December when a fuse blew in the circuitry that controls the solar panels. There is redundant circuitry on the satellite and the panels can be controlled from the ground but this is not an acceptable solution in the long run. In other respects, the satellite is functioning well, and continues to set set "healthy." The malfunctioning satellite was the first of the Block IIA satellites to be launched but used virtually the same control circuits and solar panels as the earlier nine Block II spacecraft. This failure could delay the launch of further satellites until the problem is isolated. The USAF Space Systems Division believes the problem could be generic and may result in a delay in the next launch of up to six months while the spacecraft in the launch pipeline are fixed. The next launch was to have been in February. (Source: AW&ST, 14 January 1991) ============================================================================== Richard B.

Rose, NASA Assistant Administrator for the Office of Commercial Programs, today announced that the University of Tennessee-Calspan's Center for Advanced Space Propulsion (CASP), Tullahoma, has selected three industrial firms for establishing launch and recovery of the unmanned, Earth-orbital Commercial Experiment Transporter (COMET) space system. Joe Pawlick, Assistant Director for Commercial Transportation and COMET Program Manager at CASP, said "We're taking the initial step toward establishing an entirely new U.S. industry. When successful, Centers for the Commercial Development of Space (CCDS) payloads and those of their industrial partners will be placed into and returned from the unique environment of space by COMET." The contractors selected and their component responsibilities are: o Space Industries, Inc. (SII), Houston, - payload integration, orbital operations and recovery system and services o Space Services, Inc. (SSI), Houston, a division of EER Systems - launch vehicle and services o Westinghouse Electric Co., Millersville, Md. - systems engineering and service module Upon completion of contract negotiations by CASP, such contracts will be prepared for inclusion in the CCDS grant by NASA who has budgeted $10.5 million in 1991 as initial funding for COMET. CASP is one of seven NASA CCDSs involved in the establishment of COMET. The COMET launch vehicle will place a service module and a recovery system, called a freeflyer, into a 300 nautical mile Earth orbit at a 40-degree inclination to the Equator. The 1,800-pound freeflyer will be released with payloads aboard both the service module and recovery system. The latter system will contain about 9 cubic feet of payload volume while another 6 cubic feet will be in the non-recoverable service module. The recovery system will separate from the freeflyer after about a month in orbit to be retrieved at a southwest U.S. location. The service module is designed to support non- recoverable experiments for at least 100 days after the recovery system reenters. SSI's and SII's licensing of COMET for launch from either NASA's Goddard Wallops Island Flight Facility or Cape Canaveral will be governed by U.S. Department of Transportation (DOT) regulations. CASP is responsible for COMET program management and systems engineering. The Center for Advanced Materials, Columbus, Ohio, will provide screening and selection services for COMET payloads. The other five centers and their responsibilities are: o BioServe Space Technologies, University of Colorado, Boulder - recovery system and services o Center for Power, Texas A&M University, College Station - service module o Consortium for Materials Development in Space, University of Alabama, Huntsville - launch vehicle and services o Center for Macromolecular Crystallography, University of Alabama in Birmingham - payload integration o Space Vacuum Epitaxy Center, University of Houston - orbital operations ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |___ M/S 301-355 | It's 10PM, do you know /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | where your spacecraft is? |_____|/ |_|/ |_____|/ | We do! ------------------------------ Date: 28 Jan 91 18:39:14 GMT From: elroy.jpl.nasa.gov!jato!mars.jpl.nasa.gov!baalke@ames.arc.nasa.gov (Ron Baalke) Subject: Galileo Update - 01/28/91 GALILEO STATUS REPORT January 28, 1991 Over the weekend both the USO (Ultra Stable Oscillator) and the sun acquisition activities were performed successfully with the Galileo spacecraft. However, two unexpected lock change telemetry indications were observed at the start of yesterday's tracking pass with the Canberra 70 meter station. At the end of tracking pass on January 26, all spacecraft telemetry was normal. These latest unexpected indications are in addition to those observed on January 22, and have caused no abnormal operation. Galileo continues to properly receive and process all commands. Today, a command was sent to reset the Command Loss Timer and a cruise science memory readout for the DDS (Dust Detector) and MAG (Magnetometer) was successfully performed. Tomorrow, another sun acquisition activity is scheduled. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |___ M/S 301-355 | It's 10PM, do you know /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | where your spacecraft is? |_____|/ |_|/ |_____|/ | We do! ------------------------------ Date: 28 Jan 91 19:31:35 GMT From: elroy.jpl.nasa.gov!jato!mars.jpl.nasa.gov!baalke@decwrl.dec.com (Ron Baalke) Subject: NASA Headline News for 01/28/91 (Forwarded) [Note: Peter Yee is on travel, and I will be posting the NASA updates during his absence............Ron Baalke] NASA Headline News Internal Communications Branch (P-2) NASA Headquarters Monday, January 28, 1991 Audio Service: 202 / 755-1788 This is NASA Headline News for Monday, January 28, 1991 Today marks the fifth anniversary of the Challenger STS 51-L accident. In the 28 months since NASA has returned to flight, the Shuttle has flown 13 times. These missions have deployed Magellan, Galileo, Ulysses and the Hubble Space Telescope, retrieved the Long Duration Exposure Facility and flown the Astro Spacelab mission. * * * * * * * * * * * * * * * * * * * * * * * * * * Kennedy Space Center technicians finished structural leak checks of Discovery over the weekend. Final payload bay door closeout activities were deferred because of payload bay cleaning activities. Rollover could be delayed a day or so because of work associated with leak and brazing inspections on three aft thruster assemblies. Two of the thrusters are on the left orbital maneuvering system pod and are being leak tested. One of the thrusters is on the right OMS pod and may have a questionable weld. KSC and vendor technicians are carrying out inspections and tests on these items today. Discovery is set for a Department of Defense mission in March. Over the weekend on Atlantis, workers successfully re-brazed a check valve in the main propulsion system inside the orbiter's aft compartment. The orbiter nose cap was also installed. The main engine flight readiness test will occur today. Other activity on Atlantis, in preparation for its April STS-37 Gamma Ray Observatory deploy mission, will include the installation of the forward reaction control system this week. The STS-37 solid rocket booster stack is nearly complete in the Vehicle Assembly Building. Workers attached the forward segment to the right booster over the weekend. The forward assembly will be mated early this week. The external tank will probably be mated to the SRB stacks this week. There is very little activity on Columbia, as it is, at this point, waiting for Discovery to roll out from the OPF. * * * * * * * * * * * * * * * * * * * * * * * * * * The STS-39 Payload Readiness Review was held at KSC on January 24. No major issues were raised during the meeting, and all members of the STS-39 payload community agreed the payloads are ready to be transported to the launch pad. Two of the payloads are already inside the orbiter middeck, and three more are located in the payload bay. The AFP-675, IBSS and STP-1 payloads are in the Vertical Processing Facility and scheduled to be taken to Pad 39-A on or about February 3. * * * * * * * * * * * * * * * * * * * * * * * * * * Tomorrow will be a busy day for those media which cover NASA.
