[perhaps repost your previous post? 8-) ] Ok, we now have 4 potential solutions (HL-20, Soyuz, 2xPLS above); Soyuz is $65 million per flight and $500 million to adapt (massively pessimistic) for three people and 6 months in orbit. HL-20 is $400 million per flight and $2+ billion to develop for eight people and two plus years in orbit. PLS projects are ~$1 billion to develop and probably at least $350 million per launch (just the titan is most of it) for around ten people. Per person costs per launch (ignoring dev.) are $22m, $50m, $35m each. Additionally, if we go with HL-20 or PLS, we have a significantly bigger vehicle than the crewsize will be before 2005 8-), thus we're wasting a bit of resources. Or maybe we can sell John Denver a week at Fred... As you've said, neither PLS nor HL-20 is going to Phase B anytime soon, though it's easy to point out that if they don't, we won't have a ACRV for PMC Freedom (or for several years later 8-( ). NASA gets half credit for knowing it needs one and fails the exam for not acknowledging it and trying to solve the problem by the time the need is real... 8-( -george william herbert gwh@soda.berkeley.edu gwh@lurnix.com herbert@uchu.isu92.ac.jp until 28 aug ------------------------------ Date: P From: P Received: from VACATION.VENARI.CS.CMU.EDU by isu.isunet.edu (5.64/A/UX-2.01) id AA09664; Wed, 12 Aug 92 02:16:20 EDT Received: from crabapple.srv.cs.cmu.edu by VACATION.VENARI.CS.CMU.EDU id aa01945; 12 Aug 92 2:08:22 EDT To: bb-sci-space@CRABAPPLE.SRV.CS.CMU.EDU Path: crabapple.srv.cs.cmu.edu!cantaloupe.srv.cs.cmu.edu!das-news.harvard.edu!ogicse!uwm.edu!cs.utexas.edu!uunet!fornax!glennc From: Glenn Chapman Newsgroups: sci.space Subject: Russian/French crew returns from Mir space station Keywords: Space, Russian, French Message-Id: <1992Aug11.162425.25081@cs.sfu.ca> Date: 11 Aug 92 16:24:25 GMT Article-I.D.: cs.1992Aug11.162425.25081 Organization: CSS, Simon Fraser University, Burnaby, B.C., Canada Lines: 29 Sender: news@CRABAPPLE.SRV.CS.CMU.EDU Source-Info: Sender is really isu@VACATION.VENARI.CS.CMU.EDU The Russian/French "Antares" to the Mir space station landed today (Aug. 10) after a 12 day flight. Onboard the older Soyuz TM-14 were CIS (Commonwealth of Independent States) cosmonauts Alexander Viktorenko and Alexander Kaleri, who spent 146 days in space (since Mar. 17th) and Frenchman Michel Tognini (who went up in the Soyuz TM-15 on July 27). The majority of the experiments performed during this mission were medical in nature. Staying on board the Mir complex were the remaining Soyuz TM-15 crew, cosmonauts Anatoli Solovyov (also Soyuz TM-5 to Mir June '88 for 9 days and Soyuz TM-9 to Mir in Feb. '90 for 180 days) and Sergei Avdeyev (first mission). Solovyov and Avdeyev will be staying until the Jan. 1993 CIS/Israeli visit. (Radio Moscow) In another area the company formed to continue the building of the Proton booster is offering Ariane class geosynchronous satellite launches for 66% of the current costs. Current Ariane flights cost $85 million, but Krunichev Enterprises, combined with the KBSalyut design bureau, are offering missions for $56 million. Under a June 17th agreement with the U.S. the CIS will be allowed only a single commercial launch of western satellites. However more flights will be allowed if they offer "fair prices" - raising them to U.S. and European levels.
