Seems a shame to build spacecraft and not get information from them [aside from 'Can a payload be sent to Mars using a solar sail for propulsion?]. Given that the payload is very small, I doubt there is room onboard for much. I can think of uses for the sailcraft after the race. They could be used to study solar wind above the sun's poles. Even if all we can do is observe the behavior of the sailcraft with Earthbound telescopes, they might provide useful information by reacting to forces we normally don't get to observe [even indirectly]. It's like using dandilion seeds to track the wind.

All the descriptions I've read on the safe handling >of Pu emphasise how dangerous it can be, both chemically and radiologically. I recall a book by him (I think it was him, at least it was _someone_ who offered to eat as much plutonium as caffeine.) He explained that plutonium is many times less toxic when eaten then when inhaled. He also offered to inhale a hundred particles (in response to someone who claimed that just one particle could cause cancer, but who didn't bother stating things such as probabilities. I forget exactly how many cigarettes this was equal to, but the number was low). There was also a complaint about some newspaper having confused the two, saying he'd inhale as much plutonium as he would eat caffeine (which would indeed kill him, because of the wide difference in toxicity when eaten and inhaled) and the newspaper refusing to retract it. -- "And they shall be cast out where there is no outlet for their evil doings..." -- the Book of Ubizmo, on sinful uses of electricity Kenneth Arromdee (UUCP: ....!jhunix!arromdee; BITNET: arromdee@jhuvm; INTERNET: arromdee@crabcake.cs.jhu.edu) ------------------------------ Date: 4 Jun 90 18:24:22 GMT From: trident.arc.nasa.gov!yee@ames.arc.nasa.gov (Peter E.

Phillips NASA Public Affairs/KSC 407/867-2468 ASTRO-1/STS-35 The payload team continues to monitor the Astro-1 payload as the launch team investigates the source of a hydrogen leak that scrubbed the STS-35 launch attempt on May 30. Since the Broad Band X-Ray Telescope was serviced with solidified argon on May 27 in preparation for launch, the telescope is still protected by the cooling provided by two dewars of argon. At present, launch managers have decided not to reservice BBXRT until further tests are performed on the orbiter/external tank this week. Since the May 27 servicing prepared the telescope for a 10-day mission, the instrument's health will not be af- fected. BBXRT does not require servicing with argon coolant un- til June 11. Each of the two dewars carries 97 pounds of argon. About 3 to 4 pounds per dewar were used during the STS-35 launch attempt. As part of the maintenance procedure, valves will be commanded to open to allow venting as the argon reverts to a gaseous state. In essence, the BBXRT cooling system will operate as though it were in flight. Decisions as to the type of reservicing -- liquid or solidified -- will be made later in the recycle process. The BBXRT has been serviced over two dozen times since its arrival at KSC in October, l989. Solidified servicing has been used before the trip from the Operations and Checkout Building (O&C) to the Orbiter Processing Facility (OPF) for installation in Columbia; before the move from the OPF to the Vehicle Assembly Building (VAB) for mating with the stack and then the move to Launch Pad 39A, and again before the May 30 launch attempt. SPACELAB LIFE SCIENCES 1 (SLS-1)/STS-40 The integrated SLS module was moved into the Cargo Integra- tion Test Equipment (CITE) test stand in the Operations and Checkout Building May 31. This move is a major milestone in the SLS processing. The CITE stand was designed and constructed to serve as a stand-in for the Space Shuttle. This allows impor- tant data and communications checkouts to be performed without having to use the orbiter itself. The CITE testing and verifica- tion is considered the highest level of integrated testing the payload undergoes before being installed in an orbiter. Prior to the move, the SLS-1 payload successfully completed the Mission Sequence Test in mid-May. Other pre-move operations included the installation of insulation. INTERNATIONAL MICROGRAVITY LABORATORY (IML)/STS-42 The IML module was moved into Test Stand 2 at the O&C build- ing June 1. There, the equipment will continue to undergo testing and integration. Buildup activities are continuing for other elements of the payload. The experiment rack staging and integration continues. The racks will be mated with the floor one-by-one. Once the racks and floor are mated and tested, they will be moved to Test Stand 2 later this summer for insertion into the module. ------------------------------ Date: 4 Jun 90 18:25:09 GMT From: trident.arc.nasa.gov!yee@ames.arc.nasa.gov (Peter E.

On completion of the final "orbit" of the mapping test, the radar was turned off and the spacecraft subsystems were returned from orbital operations to cruise configuration. Last week's star calibrations were all successful with an average daily attitude update of 0.09 degrees. Solar panel output now exceed 1000 watts as the spacecraft continues to approach the sun and Venus. Cruise sequence load 24 was uploaded last Friday.

Kennedy Space Center itself probably couldn't be built today. I just hope the next space port is built in a reasonable friendly country (e.g. Cape York) so Americans at least get access to it. Hah! You ought to try building something in Australia and getting an EIS passed! I 100% expect the Cape York proposal to die under exactly the same political-use-of-EIS that you seem to be concerned about in the U.S. You should have heard the noise when they wanted to build a _road_ through the same sort of area. As for nasty, big, loud, chemically polluting and highly explosive rockets... We are living in green times, especially in Australia, and I think it may be the end of large scale projects like this.
