Besides, you can say anything you want and nobody knows who you are. You seem to enjoy accusing everyone of being insecure, paranoid control freaks. At the same time you choose to support the fact that people have yet another way to avoid accountability for their actions. Wonderful. Anonymous posting have their place in CERTAIN groups. If I or anyone else needs to tell you what those groups are then you've been on another planet breathing exotic gases for too long. Sci.space certainly is NOT one of those groups.

The rumours have suggested that part of the Administration's NASA budget request for 1994 will be money for SSF termination liabilities. Canada has put somewhere between $500M and $1 Billion into developing MSS; if the Clinton space station has no place for MSS, I wonder how much of that cost he's going to be willing to refund to Canada?

My understanding is that this type of ratio between uplink and downlink is typical--caused, no doubt, by the presence of such exotica as He cooled maser amplifiers in the DSN ground stations. As the uplink doesn't contain any science data, the descrepancy in rates isn't a problem. Commands aren't all that long. But not all that long at 125 bps is a hell of a long time at far less than 10bps. If the Galileo downlink is only 10 bps (or, hopefully, 40 bps due to DSN improvements) at Jupiter, what is the uplink rate, and how will that effect engineering?

The Flight Team reports that spacecraft subsystems and the instrument payload are performing nominally. The spacecraft is in Array Normal Spin in outer cruise configuration, with uplink and downlink via the High Gain Antenna; uplink at 125 bps, downlink at the 4 K Science and Engineering data rate. The Payload Data System is active and the Gamma Ray Spectrometer is taking calibration data. Yesterday's status report stated that the Flight Software Build 8.0 Design Review which took place this morning was the Final Review. In fact, today's review was the Preliminary Design Review. Flight Software engineers presented their rationale for changes in the Flight Software to the Mission Manager, the Flight Engineering Office Manager and various FEO team members, and Flight Operations Office management. The selection of the Power-In maneuver Aim Point was made today, finalizing the overall maneuver design process. The Power-In maneuver, so named by the burn of bi-propellant powered thrusters required to perform it, is being undertaken to shorten the length of time between the Mars Orbit Insertion maneuver and achievement of the desired orbit for Mapping activities to begin. Utilization of Power-In will allow more time for successful deployment of the spacecraft into the mapping configuration prior to the beginning of the command moratorium during solar conjunction. Science will be able to advance the start of the mapping phase, allowing clear observations of the planet surface before the beginning of the Martian dust storm season which begins just after solar conjunction. Science data will be acquired for one complete mapping cycle prior to solar conjunction. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@kelvin.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |__ M/S 525-3684 Telos | If you don't stand for /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | something, you'll fall |_____|/ |_|/ |_____|/ | for anything. ------------------------------ Date: 19 Feb 1993 15:43:34 -0500 From: Pat Subject: Mars Rescue Mission, what if! Newsgroups: sci.space Zubrins Mars Direct Proposal calls for a redundant stage/supply dump system. Send a fuel factory/ supply dump ahead where it makes fuel for two years. then Send another fuel factory and supply vehicle along with the astronauts. Tha astronauts attempt a precision landing at factory 1. If they make it. great put the other one somewhere within 400 miles of their current base. If they miss, by a small amount, they travel to the dump by crawler. If they miss by a large amount, they land the second factory at their location. If they miss by a small amount, they travel to the dump by crawler. If both fail, they weather in, and radio for an emergency launch of another factory ship. Viking made precision landings using on board computers, I imagine, this plan should work fine. Now for a medical emergency, they just have to cope. llike the military and the pioneers.

Edwards" Subject: Measurement units for SSF and SSTO Newsgroups: sci.space As has been reported before, all of the previous incarnations of Space Station Freedom used the old English measument system instead of SI (metric). Is the new design incarnation still going to be measuring both force and mass in pounds? Is the truss (if present) still going to measured in feet? Will the perigee and apogee still be given in nautical miles? (Sailing, sailing, over the bounding main ...) I have heard that NASA has thought that teaching SI to the current astronaut corps is "too demanding". Golly, if it meant a chance at going into space, I'd learn Sumerian clay cuniform notation if it were needed. If NASA is worried about contractor upgrade and conversion costs, the questions are "if not now, then when?" and "if not the US contractor community, then who?". Some of the SSTO documents posted to this newsgroup also gave specification measurements in units of pounds and feet. I hope that this isn't what's on the blueprints. If the above projects are intended for the 21st century, then it seems doubtful that they should use a measument system that is already out of date now in the 20th century. If the above projects are intended to be used by the international community, then it seems doubtful that they should use a measurement system employed only by old timers in a single country. This is doubly true if hardware contributions are also expected from other countries. [The above opinions expressed are my own; not necessarily held by others.] == Steven J.

I am speaking in directed regard to the space program.

To stand on the sidelines and holler is no better at best than monday morning quarterbacking.

If private industry is such a balm to getting the job done, then there is no reason for massive overruns and failed businesses as we saw for years in the basic industries of the Country. A case in point is Rockwell's contract for the Shuttle Endeavour. Congress Allocated the money that Rockwell said it would cost for a new orbiter. Rockwell who is micromanaged by NASA as much as it is for any other program completed the orbiter on time and under budget. This does not answer fully what you seem to imply there that in no way can government do a job for what they say they can but if you free up procurment and you give an agency the money that the originally request for a project to do the project and then leave them alone, then many times the job is done on time and on or under budget. An unfortunate but true fact in most of the industry is that companies low ball a contract to win it and then cry for more money later. However this is far more prevalent in the military than for NASA but it is all to existant there as well. >Note that GD testified before Congress that elimination of FARS only >dropped prices to about half what the government is currently being >charged.

I did not post that particular one. I think that probably in his sphere of endeavor Allen is quite competent.

Well I get mad when someone talks about all of the bad things going on without the nerve to get in there in the trenches and do something postive to fix the situation. I agree that sometimes an outside observers position is a valuable one. It is just that in my opinion Allen has breached the bounds by a wide margin of the role of observer and has degenerated into an partially unfounded attack, that by the content of his posts, he does not understand either the underlying biases that guide his post or, he does it with the intention to wound without then quantifiying or qualifying what he would do to improve the process or machines to get the job in space done. >>As I have challenged you before and will again.

I have seen so many times that NASA in house does a better job than the contractors do out of house. I have seen many times that due to inadequate procurement penalties for non-performance for bad work, that the guys at NASA have to make the promised delivery work after it is recieved in a non-working or marginally working condition. As to the challange, it is perfectly valid. That is what we here are doing at the UAH CCDS and even in our student group. We compete with professional companies in the IN STEP NASA program process and we win contracts. We do unsolicited proposals in our student group that gain us contracts due to the hard work we put in and the quality of the experimentation that we do. We have even aided corporations gain contracts by our ideas that enable them to perform the contracts that they get better and cheaper than their rivals. This is from experience and is not one whit of diatribe and really and truely it is not an attack on Allen. I have sent him personal e-mail telling him the how to's and why's of how we have saved NASA litterally tens of millions of dollars, while helping NASA to advance their own technology. This is not a joke it is not verbal abuse heaped on someone, that in the end I respect for at least getting out there and opening himself to verbla machete attacks, we have been doing what I challenge Allen to do, we have done it successfully and are doing more and more of it and if you don't watch out we will one day outdo the big boys in space. All I want is for those who do attack, to back it up or make it better by entering the fray or back of and let us do it.

Should we look at higher altitudes and and steeper inclination orbits? If we went to 48?? degrees, we could still launch from KSC yet also get Russian access for not a lot of cost? I do like the idea of a 4.8 billion dollar go certainly that's a much more do-able and defendable figure. Will NASA also look at SSTO?

Goldin for a "better, faster, cheaper" space program, two southern California chapters of the National Space Society plan to unveil the initial draft of a new approach to lunar exploration at an upcoming event in Riverside. During a presentation to be held on Saturday, February 27 at 2:30 pm at the Riverside Library, located at 3581 7th Street in downtown Riverside, OASIS and the Inland Empire Space Group will provide the details of their plan to introduce the Back to the Moon bill, formally known as the Lunar Resources Data Purchase Act, during the 103rd Congress. The Back to the Moon bill would authorize the Federal government to purchase lunar science data from private vendors selected on the basis of competitive bidding. It is expected that this new concept will result in more economical lunar missions, allowing the United States to restart its lunar exploration program, stalled since 1972.
