NASA mission managers cancelled today's planned launch of Discovery for the STS-39 mission at 1:15 am this morning. The cancellation was based on the failure of a transducer on the high pressure oxidizer turbopump on main engine #3. The Kennedy Space Center launch team is in the process of detanking and safing the orbiter now. Once the safing operation is completed, engineers will enter Discovery's aft compartment to perform troubleshooting procedures. The launch team is currently working on an extended turnaround schedule for the STS-39 mission, but the earliest possible date for a launch would be Sunday, April 28. STS-39 crew members Mike Coats, Blaine Hammond, Gregory Harbaugh and Donald McMonagle will fly back to Houston and return to Kennedy by Friday. Crew members Richard Hieb, Guy Bluford and Charles Veach will remain in Florida. * * * * * * * * * * * * * * * * Marshall Space Flight Center Gamma Ray Observatory scientists report that their Burst and Transient Source Experiment instrument detected its first gamma-ray burst last Thursday, April 18. Gamma-ray bursts are mysterious flashes of gamma-ray energy which occur randomly in different positions of the sky. The bursts are so powerful that they release in just 1/10 of a second the energy our Sun releases in a thousand years. Dr. Gerald Fishman, Marshall, is the principal investigator and reports that this first observation confirms that their instrument is working. The next day, the instrument experienced what is probably a computer chip malfunction. The chip is on a redundant circuit board. The backup circuit for that function is operating now and the instrument is operating at 100 percent of its capabilities. The Gamma Ray Observatory will be pointing at the Crab Nebula for the remainder of the week so that the four instruments on board can be calibrated. * * * * * * * * * * * * * * * * The Jet Propulsion Laboratory yesterday awarded a $145 million contract to Loral Corp. to design and build the Atmospheric Infrared Sounder instrument, to be flown aboard the first of the Earth Observing System satellites, now scheduled for launch in 1998. The infrared sounder will be a global thermometer and will measure atmospheric temperature profiles with an accuracy of one degree, Celsius. Principal Investigator for the instrument is JPL's Dr. Moustafa Chahine. The instrument is expected to operate continuously for five years. * * * * * * * * * * * * * * * * Stennis Space Center education specialists held Early Education Monday last week for 170 students at two schools in Mississippi and one school in Louisiana.

The Consortium is a NASA Center for the Commercial Development of Space affiliate. A preflight press briefing on the mission and the 10 experiments will be held at 1:00 pm, Friday, May 3.

Good luck trying to get any aerospace contractor to take a fixed price contract. I know McDonnell Douglas, General Dynamics, and Lockheed are staying far away from them. The hazards of fixed price contracts should be clear to anyone familiar with the A-12. Many of the Avenger's problems stemmed from the fact that the Navy didn't want to give up its "good deal." >>I don't think ALS is trying to push technological envalopes. > >That's not what NASA says. The main thrust (pardon the pun) of ALS is to reduce the cost and increase the reliability of ELV's. ALS is not being designed to push the performance envelopes but the cost and reliability envelopes instead. If you consider that pushing the technological envelopes (which it is), then your statement is correct. But I doubt that is what the original poster meant. >>Why not just make a new one? > >Because it would cost more, take longer, and not work as well. I'm sorry >you don't find those good reasons. This is by no means certain.

Once on its way to Jupiter at least, Galileo will be having its main antenna (assuming that they do get it all the way open) pointing roughly into the sun. Now I would have thought that having such a large, thin metal surface always in sunlight, with the other side always away from the sun, would cause it to become charged, due to things like the photo-electric effect, and the fact that its treavelling thru a variable solar magnetic field. Has anyone looked at this, or is it not a big problem for the operation of the probe? H.

If it launches later, add on accordingly. There are two ways to see the Shuttle landing at Edwards AFB, listed in order of restrictiveness of access and availability. 1. The East Shore area on the lakebed. Take Hwy 14 to Avenue F and follow the signs. This area is opened about 2 days before the scheduled touchdown. The viewing area is an unimproved area so don't expect many amenities. I think that there are sanitary facilities and that food and drinks can be purchased. It's suggested that you bring food and water Nothing is required for access to this area. (I've never been to this area, so I can't speak from personal knowledge.) If any viewing is allowed this site will be open. The only times they don't open it is for the DoD's classified missions. 2. The hillside viewing area. This is on the hillside, just above Ames-Dryden, and requires a special pass. This pass is good for one vehicle, with any number of passengers. You can't enter the Ames-Dryden complex but you can walk down the hill to the cafeteria and the giftshop, etc. More amenities, including radio transmissions from the Shuttle and JSC. Some of us believe that this area has the BEST view of the landing. I believe that the Hillside, like the East Shore, is open for all unclassified missions. These passes can be obtained by writing, as detailed below. Ames-Dryden employees can also obtain them. To obtain a hillside pass, write to: NASA Ames-Dryden Flight Research Facility Attn: Ms. Cei Kratz Public Affairs Office P.O. Box 273 Edwards, CA 92523-5000 Do this early, because there is a limited amount of space. If you get these and then discover that you can't attend, please try to pass them on to someone else who can use them. Incidently, there is _no_ charge for any of these. Come see the Shuttle land--it's great. Wear warm clothes! If the Shuttle lands in the morning, it will be cool to downright cold. Forget the myth that the desert is always hot, it may be in the low 60s even in the summer at sunrise. It's frequently freezing in the winter. If it's much warmer, it's because the wind is blowing. Hillside Guests will be sitting up on metal bleachers. The portions of their anatomy in contact with the bleachers (feet and seat) may get _real_ cold. 1130 shouldn't be too bad, but if you get here early, be prepared. -- Mary Shafer shafer@skipper.dfrf.nasa.gov ames!skipper.dfrf.nasa.gov!shafer NASA Ames Dryden Flight Research Facility, Edwards, CA Of course I don't speak for NASA "Turn to kill, not to engage."

Read the rest of my post. We can be pretty sure the Saturn V will be expen- sive because it is so old. It will not be easy or cheap to re-engineer the Saturn V. Let me repeat: parts are no longer available, venders have gone bankrupt, tools have been destroyed, machinists have retired, and replacement parts will be out of spec. Expensive and time-consuming engineering will need to be done to rebuild it. -- Michael Kent mvk@itsgw.rpi.edu McDonnell Douglas Rensselaer Polytechnic Institute St. Louis, Missouri Troy, New York Apple II Forever! ------------------------------ Date: 24 Apr 91 04:48:04 GMT From: prism!ccoprmd@gatech.edu (Matthew DeLuca) Subject: Re: Government vs. Commercial R&D In article <245@rins.ryukoku.ac.jp> will@rins.ryukoku.ac.jp (will) writes: > I don't entirly agree with the Anti-trust thing, I mean if America > can allow murders to run rabid, crazies to mass murder 10+ people > and put them back on the street, allow police officers to beat up > people for enjoyment.
