The momentum is also on Freedoms side. Last Freday there where only 70 votes in favor of the amendment to restore Freedom funding.

What's with this United Space Federation. Is it a big joke or what. All I read on this net from the USF is the same rhetoric about the cold war, the military industrial complex, war time economies, etc., etc., etc. I don't necessarily want to see all the money that was going for defense $$$ going to space programs. I'd like to have my taxes cut so I can afford to live a little. People in the defense industry will just have to learn a new trade. I did. That's the way it goes in any industry. If you just get everyone focused on some grandiose world space program, we will still have the same socioeconomic problems. We as a species haven't yet learned to live together and I doubt that focusing on colonization of space is going to solve that problem. We will just bring the same social ills into outer space with us. Hopefully there will be some kind of intergalactic space police to keep us under control. |--------------------------------------------------------------------| | Bob Rehak, DBA At Large, BITNET: A20RFR1@NIU | |--------------------------------------------------------------------| ------------------------------ Date: 10 Jun 91 09:00:21 GMT From: swrinde!cs.utexas.edu!sun-barr!newstop!exodus!norge!jmck@ucsd.edu (John McKernan) Subject: Re: orbiter production In article <53769@apple.Apple.COM>, han@Apple.COM (Byron Han) writes: |> If we are not going to do manned space flight, why are you proposing |> spending money on regenerative life support, space suits, etc? |> |> Shuttle being able to launch people into orbit is certainly a very unique |> capability when compared to Titan IV. It depends on your goals in manned space. If your only goal is to get a few men into orbit for a year or less at a time, then 30+ billion dollars will get you to that goal via the space station. If your goal is to develope technology that will allow space industry and colonization, then the space station, and the space shuttle, are not a wise expenditure of limited manned space R&D funds. That's because there is a lot of R&D that needs to be done to achieve the second goal, and a lot of that R&D does not require men in space at this time. One of these R&D areas is launch technology, and progress in this area will in the future allow R&D requiring men in space to proceed with a much greater R&D return for much less money. So the space shuttle and the space station are an appalling waste of money at this time because changing the order in which we research manned space technology so as to do research requiring men in space later, will allow us to make much more progress in less time and for less money.

Put the following in the sci.space kill file: /talk.politics.space/h:j This will kill any file which has been crossposted from talk.politics.space (or whatever). This way you only read an article once (when you go to t.p.s.). I do this with sci.space.shuttle that I only see an article once, rather than seeing it repeated in two newsgroups.

Is it the mirco-gravity at 180 miles up? To measure mass in the absence of gravity, you can apply a force and observe the resulting acceleration. For example, put your object in a centrifuge and spin it at a known rate about a known radius. Measure the force it exerts on the centrifuge by means of a spring or other devise. Then Mass = Force * Radius / V^2 To measure the mass of a space-craft, fire a rocket engine of known thrust and measure the resulting acceleration.

I strongly agree that sci.space.policy is a much better name for the proposed news group. A discussion about current and potentially improved space R&D management, as well as discussions about future space R&D directions is not a discussion about politics, it's clearly about space policy. Also, the contents of sci.space.policy will come out of topics that are currently discussed in sci.space, and the large majority of those interested in sci.space.policy will also be interested in sci.space. So it makes a lot of sense to reflect the fact that the contents of the proposed news group is a subset of the parent news group sci.space, and to place the proposed news group in the name space where those interested in sci.space could easily find it.

Conditions intensified around 05:00 UT and have reached severe storm levels over the middle and high latitudes. Significant geomagnetic and auroral storming are being observed. There is a high probability for low-latitude auroral observations this evening (04/05 June) and tommorrow evening (05/06 June). Continued major geomagnetic storming could be observed if solar Region 6659 continues to produce strong solar flares. Major flaring is expected to continue. A polar latitude HF radio blackout has been observed due to intense solar proton bombardments. Absorption over the high latitude and polar regions will remain capable of producing long-duration HF blackouts over the next 24 to 48 hours, at least. Further major flaring could degrade conditions even further. A significant probability for VHF auroral backscatter exists over the low, middle and high latitude regions. Conditions are very favorable for VHF backscatter communications over widespread areas. Auroral storming is very high at the present time. This is a very strong geomagnetic and auroral storm. No significant improvements are anticipated over the next 12 hours. Conditions over the sunlit hemisphere will be less severe than conditions on the nightside. An update will be posted later this UT day. /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ ------------------------------ Date: 10 Jun 91 11:35:28 GMT From: world!ksr!clj%ksr.com@uunet.uu.net (Chris Jones) Subject: Re: IGY and the beginning of the Space Age In article <4cIc1gy00WBNM19VUv@andrew.cmu.edu>, lc2b+@andrew (Lawrence Curcio) writes: >As I recall, IGY was 1956.

Crew are Bryan O'Connor, Sid Gutierrez, Dr. Rhea Seddon, Dr. Jim Bagian, Dr. Tamara Jernigan, Dr. Mille Hughes-Fulford, Dr Andrew Gaffney, several rats, and many jellyfish. Soyuz TM-11 undocked from the Mir complex and landed on May 26. Aboard were the long stay crew Viktor Afanas'ev and Musa Manarov, and Soyuz TM-12 researcher Helen Sharman of England. The Mir/Kvant/Kvant-2/Kristall/Soyuz TM-12 complex is now crewed by Anatoliy Artsebarksiy and Sergey Krikalyov. The Progress M-8 cargo craft carrying supplies and fuel for the station was launched from Baykonur on May 30. Musa Manarov landed with 540 days 22 hours and 31 minutes spaceflight time accrued over two missions to Mir, beating Yuriy Romanenko's record for cumulative spaceflight time by over 100 days, and the US record by over a factor of six. The 10th Resurs-F remote sensing satellite was launched on May 21 from Plesetsk. It carries an MK4 multispectral camera, and is based on the Vostok spacecraft. Kosmos-2149 was launched on May 24 from Plesetsk. It is an imaging recon satellite and will remain in orbit for 2 months. It replaced Kosmos-2138 which was deorbited on May 24 after 59 days in space. Aurora 2, a communications satellite for GE Alascom, was launched by a Delta 7925 on May 29. The GE 3000 class C-band comsat will replace the Aurora 1 which was launched in 1982. TIP 2, a US Navy experimental navigation satellite, reentered on May 26. It was launched in 1975. Kosmos-151, an electronic intelligence satellite launched in 1967, reentered on May 6. Delta 111, the second stage of the launch vehicle which orbited Nimbus 6 in 1975, exploded into hundreds of fragments about May 14. The Delta stages of that era had a habit of exploding years after launch, due to the detonation of left over propellants. More recent Delta launches have burned up all their propellants to avoid this problem. ___________________________________ |Current STS status: | |Orbiters | | | |OV-102 Columbia LC39B | |OV-103 Discovery OPF Bay 1 | |OV-104 Atlantis OPF Bay 2 | |OV-105 Endeavour VAB Bay 2 | | | |ML/ET/SRB stacks | | | |ML1/STS-43 VAB Bay 1 | |ML2 | |ML3/STS-40/ET/OV-102 LC39B | ----------------------------------- 10 years ago: 31 May 1981.
