Yee) Subject: NASA Headline News for 09/22/89 (Forwarded) ----------------------------------------------------------------- Friday, Sept. 22, 1989 Audio report: 202/755-1788 ----------------------------------------------------------------- This is NASA Headline News for Friday, September 22nd...... Aerospace Daily reports that Senator Howell Heflin says he would like a space station summit agreement between Congress and the Bush administration. Heflin said on the Senate floor yesterday that he believes a summit agreement is necessary to avoid what he called "yearly life or death" fights over the space station budget. Heflin said he has discussed the proposal with President Bush, who appeared "very receptive." Meanwhile the Senate yesterday completed debate on the FY '90 Appropriations Bill which includes $12.3 billion for NASA. Once passed by the Senate, it will be sent to a joint conference committee to iron out differences between it and a House version approved in July. The Senate bill includes $1.85 billion for the space station, compared to $1.65 billion in the House version. At the Cape...technicians have moved the Rotating Service Structure back into place around Atlantis. Today, workers will continue making connections between the launch pad and the orbiter and launch platform. Early next week, the payload bay doors will be opened and a Partial Interface Verification Test will be conducted to verify those reconnections between the Galileo/Intertial Upper Stage and the orbiter. Launch date impacts due to preparations for hurricane Hugo are currently being accessed. A New Zealand scientist said yesterday a hole in the ozone layer over Antarctica has grown far larger than experts had forecast. He said U.S. and New Zealand teams in Antarctica had taken measurements indicating remaining ozone quantities were 20 percent lower than in 1988. The scientist said the hole "appears to be following a track very similar to 1987 which led to very great ozone depletion." A Richmond, Virginia Circuit Court judge yesterday postponed a request by the state Attorney General to shut down the Avtex Fibers, Inc. rayon plant. The state contends the plant is polluting the Shenandoah River with PCBs. Avetex produces a rayon fiber used in space shuttle motors. Lawyers for Avtex argued yesterday that they had not been given sufficient time to prepare for the hearing. They said if the temporary injunction were granted and the company were forced to shut down, it would go bankrupt and never reopen. ************* ----------------------------------------------------------------- Here's the broadcast schedule for public affairs events on NASA Select television.

I would like the earth to be treated the same way by our own life forms! However, is it not typically human to assume that we can do as we please with new lands (planets) that are discovered? I make this statement based on the historical examples that occurred when North, Central, and South America were discovered and colonized. I don't think we have grown up much since then. In fact, (correct me if I am wrong) I tend to think that the total amount of intelligence on this planet is a constant, its just that the population is increasing. :-) Hmmm...this 'Golden Rule' sounds suspiciously like the 'Prime Directive' from Star Trek: not too interfere with other life forms and civilizations.

Yee) Subject: Jerry J. Fitts appointed Deputy Associate Administrator of Office of Space Operations (Forwarded) Brian Dunbar Headquarters, Washington, D.C. September 21, 1989 RELEASE: 89-147 JERRY J. FITTS APPOINTED DEPUTY ASSOCIATE ADMINISTRATOR OF OSO NASA Administrator Richard H. Truly today announced the appointment of Jerry J. Fitts as the Deputy Associate Administrator for Space Operations, effective Oct. 8, 1989. Fitts will succeed Charles T. Force, who was appointed the Associate Administrator for Space Operations in July 1989. The Office of Space Operations manages the agency's worldwide data and tracking network, which tracks and communicates with all manned and unmanned spacecraft and interplanetary probes. Fitts received a Mechanical Engineering degree from the University of Utah in 1958, followed by a master's of science degree from Rensselear Polytechnic Institute. Fitts' first engineering position was with Pratt and Whitney Aircraft working on propulsion systems development. He then accepted an opportunity with General Dynamics to participate in NASA's Centaur Program, the nation's first liquid hydrogen/oxygen rocket. In 1962, Fitts joined NASA's Space Nuclear Propulsion Office, where he ultimately became responsible for engine systems design and development at the Lewis Research Center. Fitts left NASA to help establish the Office of Research and Technology at the Department of Housing and Urban Development. He was Director of the Housing and Economic Research Division for 6 years. In 1980, Fitts returned to NASA as the Deputy Director of the Space Shuttle Main Engines Program within the Headquarters Office of Space Flight (OSF). Subsequently, Fitts served in OSF as Director, Solid Rocket Booster and External Tank Division, and as Deputy Director, Customer Services Division. In February 1987, Fitts became the Director of the Transportation Services Office, a focal point for the NASA, DOD, civil and international payload communities that require transportation services on the Space Shuttle or expendable launch vehicles. He also was responsible for space transportations policy development and manifesting of payloads on the various launch vehicle systems. Fitts and his wife, Hartley Campbell Fitts, reside in McLean, Va. They have three children -- Stanford, Stewart and Jane Anne -- and two grandchildren. ------------------------------ Date: 22 Sep 89 19:35:15 GMT From: zodiac!IDA.ORG!roskos@ames.arc.nasa.gov (Eric Roskos) Subject: Deletion of Hurricane GIF pictures Since Hurricane Hugo is now over, and since they are taking about 4 MB of space, the hurricane GIF pictures will be deleted from SIMTEL20 in a week or so. If you want any of them, be sure to get them while they're still there. To review, they are on PD3: on WSMR-SIMTEL20.ARMY.MIL. They require a GIF viewer that supports (at least) 16 shades of grey to be viewed properly; a VGA seems to be necessary to view them on a PC. -- Eric Roskos (roskos@CS.IDA.ORG or Roskos@DOCKMASTER.NCSC.MIL) ------------------------------ Date: 22 Sep 89 15:12:43 GMT From: china.uu.net!dan@uunet.uu.net (Dan Williams) Subject: Interplanetary Contamination 'mail' from Mars. Says that organic material from Mars came along for the ride. Organic carbon and Nitrogen Materials were found in the meteorite. This fining was released by British scientists at the Open University in Milton Keynes. Dr Ian P. Wright in the journal Nature reported that this was the first "organic connection" with Mars yet to be found. So I don't think this rock was too sterile when it hit earth. This may indicate that planets in our solar system are not quite as closed as the hysteria generated by Galileo's plans to probe Jupiters atmosphere warrants. Think of it as just another meteor. Maybe we could get Dan Quail to support a mission to Mars so we could request that they sterilize any meteors they eject from now on. So how hard was Mars hit to eject material to Earth?

Terrestrial microbes have already been introduced to Mars via Soviet landers. While they crashed, they were NOT sterilized. Whether the microbes could have survived is another story. Some terrestrial organisms _can_ , but would a water bear have been on these vehicles? Plus, survive and reproduce effectively are two different things. What about terraforming Venus with modified organisms -blue-green algae, or maybe the hydrogen-sulfide eating bacteria from the ocean vents? Can any life have survived on Venus - assume for arguements sake only - that it did have oceans and life once?

It describes mars missions made possible by the use of nuclear thermal rockets and the nitrogen available from the Martian atmosphere. These missions would require a single ALS, Shuttle-Z (I don't know what that is), or Shuttle-C launch to place a hydrogen propellant transfer stage and a nitrogen propellant lander in LEO. The vehicles would be tethered during the voyage to provide some gravity. Upon return the vehicles could be refueled with a single Titan IV or Shuttle launch and sent back to Mars. The article is by Robert M. Zubrin of Martin Marietta Astronautics, and is rather critical of NASAs approach to a Mars landing. BTW, we already HAVE the nuclear propulsion technology to pull this off. Good Reading Bob P. P.S.
