Plus the VSE won't have any real flights (ARES I-1 doesn't count) by 2014 either
JIS - 13/2/2007 8:18 AMQuoteJim - 13/2/2007 1:11 PMHe isn't just going after tourists.So you say that non-tourists will pay more? How many non-tourists could be there?
Achilles - 13/2/2007 1:36 PMSo just using your simplified business figures, if a commercially available access to LEO is available for about 25million a seat before 2014, hows a 300million Aries I shot (@50million a seat) going to sit with the US tax-payer ?
JIS - 13/2/2007 8:55 AM1. Bigelow crew vehicle doesn't exist even on the paper (unlike Orion/Ares 1). Atlas V would make the seat price a lot higher than $25m per seat.Orion can stay at ISS for 6 months and can be used for ISS orbit adjustment too. It is very unlikely that any private ship can be more safe/reliable than Orion/Ares 1.2. But I really believe that private industry can eventually take over most of the LEO flights. I wouldn't say it happens before NASA lands on the Moon.
Achilles - 13/2/2007 9:14 AMAtlas V, Falcon 9 crewed capsule , whatever its coming sooner and it will be less that 300million a shot. Sure an Orion could stay at the ISS for six months but it wouldn't take six months of supplies with it -ie with rotation of the supply-capsules who needs 6mths duration in LEO ? ISS Orbit adjustment - ATV (certainly after 2016)NASA landed on the moon nearly 40years ago. My moneys on COTS being in LEO before the sick stick.
JIS - 13/2/2007 9:47 AMYes the CBO estimated the Ares1 cost to about the same as Delta4H ($200mil) plus launch services plus Orion.

He needs 6-8 crew ferry plus one cargo for every two crew missions each costs about $70mil.
To assembly a space hotel he needs about three assembly flights with three modules ($1-2B ?).
5 paying costumers needs to pay between (14 mil for the crew flight + 7 mil cargo =) $21mil per flight per person + some fee for the station + training + insurance to make a very optimistic business case.
Are there around 100 tourists per year willing to pay around $25mil?
The first flight of the real hardware could be before 2014 but no real component exists yet. Maybe Atlas 5 but this can hardly achieve $70mil / flight including space ship.
Achilles - 13/2/2007 1:10 AMThe likes of Bigelow and SpaceX are going to make the VSE plans look very silly before 2014.
First off, it's important to remember that Bigelow has never said he's building a space "hotel". My guess is that when the dust clears it will be more of a space research or industrial facility with a subsection being more hotel oriented.
Second off, $1-2B for the two assembly flights he actually needs? Where do you get your numbers from? I'd be amazed if he spent more than $250-500M on two or three construction flights. He isn't flying it on the Shaft of the Shuttle. He's flying it on commercial vehicles, which are a *lot* cheaper.
Quote5 paying costumers needs to pay between (14 mil for the crew flight + 7 mil cargo =) $21mil per flight per person + some fee for the station + training + insurance to make a very optimistic business case.If they can get an 8 person capsule like they think they can, the price per person all things included will actually likely be in the $8-10M range, not in the $20M range.
QuoteAre there around 100 tourists per year willing to pay around $25mil?If space tourism were his primary market, and if it was really going to be as expensive as you claim, then yes there would be a problem. But since you're off on the cost numbers by about a factor of 2x, and since space tourism per se isn't his primary market...
QuoteThe first flight of the real hardware could be before 2014 but no real component exists yet. Maybe Atlas 5 but this can hardly achieve $70mil / flight including space ship.The first flight of test hardware was last year. The first inhabitable module (Sundancer) is scheduled for sometime in 2009-2010. Even assuming they run into some snags (or that the first Sundancer doesn't work), I'd be amazed if they didn't have habitable volume on-orbit before 2012.
As for Atlas pricing, my sources say you're wrong. At low flight rates, yes they have to charge more.
But if they get even moderate demand from Bigelow, it'll double or triple their Atlas V 401/402 flight rate.
But hey, what do they know. They've only been flying rockets for 40+ years now. ;-)
Seriously, your analysis isn't *that* far off ~Jon
