After loss of the downlink telemetry, the spacecraft went into a safing mode, which automatically switched off all nine science experiments. The telemetry link was reestablished at 10:01 a.m. PDT. No scientific data have been acquired since the link was lost. The mission operations team plans to restablize the spacecraft's thermal environment and begin turning the spacecraft's science instruments back on early next week. Cause of the incident is being investigated. ##### ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@kelvin.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |__ M/S 301-355 | "Imagination is more /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | important than knowledge" |_____|/ |_|/ |_____|/ | Albert Einstein ------------------------------ Return-path: X-Andrew-Authenticated-as: 0;andrew.cmu.edu;Network-Mail Date: 20 Jun 91 00:14:53 GMT From: cis.ohio-state.edu!zaphod.mps.ohio-state.edu!usc!isi.edu!cew@ucbvax.Berkeley.EDU (Craig E.

Engineering projects like Space Station also must balance various goals and needs. Just because the AGU may not like the balance is no grounds for name calling. Furthermore, the AGU doesn't represent all "Scientists" so framing the statement like this is foolish. >2) Science is not getting 20% of the NASA budget now (17%).

I went back to my source on this one, Glenn Reynolds, and he stands by his assertion. The percentage going to space science is 20%. Meredith could be looking at just those space science projects preferred by the AGU, the rest being "bad." (Who is Glenn Reynolds and why should you listen to him? He is the chair of the National Space Society Legislative Committee. Last year he helped get The Launch Services Purchase and The Patents in Space Acts through Congress. This year, he is in charge of Spacecause efforts to get the Omnibus Space Commercialization Act through. He is a law professor at the University of Tennessee and an expert in space law.) >3) Last year's budget agreement effectively gave NASA a cap.

NASA is at a crossroads and >scientists need to be heard. This is not true. The agreement is that any increases in domestic spending programs will need to be matched decreases in other domestic programs. This gives a lot of room to maneuver. This goes to the point I made earlier about space supporters forming coalitions. (An area completely ignored by Meredith's statements.) Furthermore, the OMB gets to interpret the rules. Noting that President Bush threatened to veto any appropriations bill that lacked station funding, you can figure that OMB will bend the rules as much as it can to increase funding at NASA. This is not a zero sum game. >***************************************************************** >...However, with the budget >agreement that seems to be adhered to by both congress and the white >house, money saved in DOD cannot be used to fund civilian activities. This isn't wholly true. See my statement above about who gets to interpret the rules of the agreement. >Now that the House has passed the budget authorizing the Space Station >and cutting into Space Science, the action reverts to the Senate and >the House/Senate conference committees. And this is how we should proceed. The Senate appropriations subcommittee gets $81 billion dollars to spread around. All space supporters should work together to keep funding for the space station and to restore funds for the space science projects. (You lamented the waste in DOD, I tell you HUD is likely just as bad, if not worse.) It can be done; the better-than-expected margin of victory on the House floor will be a big boost. >The Space Station is not the whole manned >space program as pointed out by Congressman Traxler and others, The whining of a congressman about to lose big, and lose big he did. >including the very succinct and intelligent comments of the Republican >congressman from New York, Bill Green. Bill Green has always been a foe of manned space. He doesn't think people have a place in space -- he doesn't want to go so you must not want to either. >...The AGU of course is not >against manned space per se and does not agree that the loss of the >Space Station would signify an end to the manned program. This is actually what the House voted on, to have *any* manned program or not, and is one of the reasons the margin of victory was so large. This is the way the Senate will look at the question also. As another letter from space scientists posted to this list noted, fighting the space station is counter-productive. If the AGU and others fight the station, the Chapman-Lowery approach may just stand, i.e. gutting of the space science funding would be the only result from the line Meredith wants to pursue. Better if you let him charge windmills. -- Craig E.

I have never seen anybody who actually HAS a lot of money say that if NASA disappeared they would be willing to spend their own private money on large scale space ventures.

Rocket is 46 feet long (?including payload) and is launched from a rail. Rocket is a 27,000 lb Thiokol Castor 4A (normally used as a booster for Delta rockets), modified with a different nozzle and with guidance equipment How: The vehicle took off, but after about 13 seconds debris of some sort could be seen falling from the rear of the rocket. The vehicle then tumbled and the range safety officer blew it up. Payload: "Joust-1" containing 10 materials processing experiments. Intended for a sub-orbital hop giving 13 minutes of weightlessness. The payload separated from the rocket when it was destroyed but at the time of the report it was not clear whether it survived without damage. Payload implications: the launch was carried by the Consortium for Materials Development in Space by arrangement with NASA's Office of Commercial programs. A $200,000 fee was paid to insure the launch using NASA money. Presumably a refly will be scheduled. Orbital Science Implications: Prospector rockets will be grounded until it is clear what happened. Orbital says "we are confident that our team will quickly identify today's problem and that we will continue to supply reliable launch services to our customers". -- Bruce Dunn Vancouver, Canada Bruce_Dunn@mindlink.bc.ca ------------------------------ Return-path: X-Andrew-Authenticated-as: 0;andrew.cmu.edu;Network-Mail Date: 20 Jun 91 00:27:41 GMT From: tristan!loren@lll-winken.llnl.gov (Loren Petrich) Organization: Lawrence Livermore National Laboratory Subject: On the Non-Anticipation of Automated Spacecraft Sender: space-request@andrew.cmu.edu To: space@andrew.cmu.edu In a recent posting on historical precedents for different types of space ventures, I mentioned the curious non-anticipation of automated spacecraft in practically all descriptions of spaceflight before it actually happened. I suggested that Arthur C. Clarke's proposal of radio relays in synchronous orbit was a counterexample, but someone e-mailed me that even his proposal featured people coming up and replacing the tubes in the electronics. I confess I haven't read his article -- just mentions of it by ACC himself and others, and there wasn't any mention of what maintenance would be needed. It's evident that ACC had not anticipated solid-state electronic components, which do not burn out. The only maintenance problem that remains for most satellites is the question of maneuvering propellant. Interestingly, the Shuttle was advertised as a platform for doing maintenance on satellites, and some Shuttle missions have scored success there, but the Shuttle itself has been too expensive and cumbersome to allow maintenance on a regular basis. However, the Soviets have repeatedly resupplied their space stations; they have a crewless Soyuz called Progress for that very purpose. There is one feature of the non-anticipation of automated spacecraft that I had neglected to comment on. Even the spacecraft that carry astronauts are heavily automated; for most of the flight in every mission I know of, the astronauts are simply passengers. I get the impression that astronauts' control over the motion of a spacecraft has consisted mostly of reorienting it and small delta-vee maneuvers like docking; and even those sorts of maneuvers are fed through a control system. This level of automation has been necessary because one needs very precise delta-vees and directions to get to where one wants to go, though fortunately, the necessary maneuvers are rather straightforward to work out by computer. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ Loren Petrich, the Master Blaster: loren@sunlight.llnl.gov Since this nodename is not widely known, you may have to try: loren%sunlight.llnl.gov@star.stanford.edu ------------------------------ End of SPACE Digest V13 #771 *******************
