The General Accounting Office (GAO) has released a report of the costs
of Shuttle Operations. I have taken this from the 2009 figures - there were five flights, cost per flight was $596.34 million each. With a 24.4 metric ton payload this is a cost of $24.44 million per metric ton. Where would a commercial entity cut costs? Total Space Shuttle: $2,981.7 million Flight and Ground Operations: $1,031.2 million Launch & Landing: $705.5 Landing Operations $ 4.0 Mission Operations: $236.5 Flight Crew Operations: $87.6 Space & Life Sciences: $12.6 Transition: $2.0 Flight Hardwa $1,460.9 million Orbiter: $459.1 EVA: 0.2 ET: $253.6 RSRM: $301.6 SSME: $193.8 SRB: $ 154.1 SSC Test: $30.0 Transition: $85.8 Program Integration: $489.6 million System Engineering & Integration: $74.0 Safety and Mission Assurance: $54.8 Flight Softwa $100.9 Flight Operations & Integration: $54.8 Space Shuttle Propulsion Systems Integration: $16.6 Construction of Facilities: - Safety & Sustainability: - Mission Directorate Support: $12.2 Contract Administration: $25.5 Closed Accounts: $1.0 Transition: $1.5 Severance: $40.3 Here are some courses that introduce core costing concepts and apply them to aerospace systems; 6.83J Space Systems Engineering ______ Undergrad (Spring) (Same subject as 12.43J) Prereq: Permission of department Units: 3-3-6 Add to schedule Lectu T3-5 (35-225) Lab: F1-3 (35-225) ______ Design of a complete space system, including systems analysis, trajectory analysis, entry dynamics, propulsion and power systems, structural design, avionics, thermal and environmental control, human factors, support systems, and weight and cost estimates. Students participate in teams, each responsible for an integrated vehicle design, providing experience in project organization and interaction between disciplines. Includes several aspects of team communication including three formal presentations, informal progress reports, colleague assessments, and written reports. Every other year, 16.83 is the first term in the three-term capstone subject, followed by 16.831 and 16.832. Can be taken alone. D. L. Miller, S. Seager 16.866J Cost Estimation and Measurement Systems ______ Graduate (Fall) H-Level Grad Credit (Same subject as ESD.361J) Prereq: ESD.301 or a basic understanding of statistics and permission of instructor Units: 3-0-6 ______ Focuses on principals of cost estimation and measurement systems with specific emphasis on parametric models. Theories from the fields of hardware, software, systems engineering, Systems of Systems, and enterprise science will be applied to a variety of contexts (i.e., aerospace, IT, manufacturing). Material is divided into five major sections: cost estimation fundamentals, parametric model development calibration, economic principles, measurement systems, and government/ policy issues. R. Valerdi To design and build a rocket system from scratch costs between $5 million and $30 million per metric ton. Which is pretty much the cost of what it takes to put something on orbit. In a nutshell, what you do is figure out what the total structural fraction is - how many tons - for a given vehicle - and then multiply it by the estimated range of numbers from $5 to $30 million based on a number of factors (maturity of the technology, overall size of the system, overall production volume, etc.) Different systems have different costs as well. Tankage, engine, empennage, etc. One way to reduce cost is to build commodity items - like MEMS rocket arrays - and standardize on them to achieve missions. You can see the Shuttle doesn't do this. In fact, there is a resistance to do this since it adversely impacts the standing army of men and women that work to keep the Shuttle flying. This paper describes what might be possible; http://pdf.aiaa.org/preview/CDReadyM...V2005_3650.pdf At 50 pounds per square inch and $10 per square inch for MEMS rockets, and 1,000 to 1 thrust to weight - A metric ton of lift costs $440 and the device itself weighs only 2.2 pounds! It is also highly efficient, reliable, controllable, and so forth. I have developed a technique to use HDTV control methodology to control the direction as well as the amount of thrust a 'propulsive surface' produces http://www.youtube.com/watch?v=mzXwctPXT4c WIth this sort of performance (and appropriate attention paid to MEMS based and Micro-based pumps and piping) structural fractions as low as 5% are obtained. A 1,000 ton engine set forms a disk that spans 7 meters (22 ft) and lifts 720 tons take off weight vehicle that weighs 40 tons empty. The cost of the vehicle at $10 million per ton is $400 million. Reused 1,000 times costs pe rlaunch is $400,000, 680 tons at $100 per ton for cryogens is another $68,000 - operating costs less than $500,000 - total cost less than $1 million per launch. $1 billion for 1,000 launches - including vehicle purchase. The payload is 59.79 tons using hyrogen oxygen - more than double the space shuttle. The vehicle comes back and lands under rocket power like the DC-X making good use of the MEMS technology. Five vehicles would put nearly 300,000 tons into orbit over 1,000 launches for less than $5 billion. Even in large scale production the payload itself would cost $5 million per kg. So, each launch would cost $30 million on that basis. A fleet of five vehicles launched one every other day would produce 15 launches per month and have a 10 day turn-around per vehicle. Total cost $465 million per month - the same cost as a single space shuttle launch. |

COTS funds paid by NASA: $500M COTS funds paid by investors: $500M COTS extra-funds from 2011: $300M SpaceX+Orbital CRS program: $3500M TOTAL funds for R&D and ISS services: $4800M TOTAL cargo delivered to the ISS by COTS/CRS contractors: 40 tons price-per-ton of cargo carried to the ISS by SpaceX and Orbital: $4800M / 40 tons = $120M per ton that's about four-five times the price of the Space Shuttle also, the Shuttle carries 6-7 astronauts to the ISS at every flight, that, in "Soyuz seats costs" is a money saving around $300-350M for each Shuttle flight so, if we consider the saving in "Soyuz seats", the real price-per-ton of each Shuttle flight's cargo is LESS than HALF the (already low) costs calculated above... everything as already explained in this article: http://www.ghostnasa.com/posts2/061comparison.html .. |

I give up....
Tell you what 'G' why don't you start a program for private investors to take over operation of the shuttle if it's such a bargain? Dave |

Dave Sorry, but that's strictly reserved for William Mook and myself, although I'd have no problems with the gaetanomarano think-tank and its subsequent R&D responsibilities. My primary job would pertain to tranquillizing Mook from time to time, plus having a commercial stun- gun handy whenever Mook is allowed to be active. ~ BG |

Dave If you look at Boeing and Lockheed 10K and 10Q you can see that their space operations are money losers while their primary actvities - of building aircraft and missile systems - are money makers. So, if you buy Boeing, split off the space operations from the commercial aircraft operations, and sell the commercial aircraft operations - you can actually make about $8 billion. If you had a commercial use for the space faring component, this would be a way to get it funded. The simplest approach would be to build a network of satellites in polar orbit that created a global wireless hotspot, that made $80 billion or more in revenue each year. Then, power sats. Then, asteroid capture. and so forth. |

3G and beyond systems are well beyond what is doable via satellite today, I need to qualify that statement. Of course satellites can supply raw bandwidth at higher rates than 3G towers today. However, the trick is how to share that bandwidth amongst a large number of subscribers. Existing Ku band systems in GEO use CONUS style transponders, which means they share bandwidth across *all* ground stations within their range. It's like a giant party line, or if you like one big cable loop among all the subscribers nationally. Typically to make these systems pay, the sat. provider must oversubscribe. This isn't a problem until everyone gets on at the same time which is typically what happens during the hours of 4pm-10pm. During these times service crawls to a snail's pace (equiv. to an old style dial-up line). The newer Ka systems use 'spot-beam' technology which allows transponder freq. reuse between zones that lie outside the coverage 'spot'. This allows better sharing than CONUS and even allows for sat-to-sat relay, but so far there are only a handful[1] of these sats on-station and as more subscribers are forced migrate to these new systems from the more plentiful legacy Ku systems (which are largely leased, hence the move) it is unclear that service will not degrade to the same degree on the Ka systems as they become grossly oversubscribed as well. That is what exists today. Of course Mr. Mook was proposing LEO sats in polar orbit. A start-up company was founded in the early 90's to do just that (Teledesic). But it would appear the NRE costs to get to orbit, the prior commercial failures of Iridium and Globalstar and the fact that by the time the system would come on-line similar if not better performing systems would already be available to celluar customers, forced Teledesic to suspend construction work on their system on October 1, 2002. http://www.bookrags.com/wiki/Teledesic I see no evidence that the business case has improved. Dave [1] IIRC: Hughesnet, the largest satellite internet provider today, was originally to have 2 of these on-station. But because the business case for HD sat TV was far stronger than for sat internet, the first two of these Ka birds, SPACEWAY 1 & 2, were sold to DirecTV. On August 14 2007, the first Hughesnet Ka bird to provide sat internet, SPACEWAY 3, was launched and later placed into service on April 8, 2008. The nearest Ka competitor, WildBlue has 2 Ka birds on station. Actual delivered service has never lived up to the promise: http://www.broadbandreports.com/show...FAP-Caps-97011 http://www.dslreports.com/shownews/H...In-2012-103034 http://www.bbb.org/denver/business-r...age-co-9036631 |

A global ISP network of robotic airships cruising nearly effortlessly at 5075,000 feet would have been the solution as of a decade ago, as well as right now and into the foreseeable future. Most of us would never be more than 100,000 feet away from any given node, and others might be isolated by 150,000 foot distance unless you're talking Arctic/Antarctic locations that could conceivably be 300,000 foot. ~ BG |

The limitations of CONUS and other aspects are absolutely correct.
However, I have developed a technique using circularly polarized phased array antenna that paints a doppler corrected array of surface stationary virtual towers across the surface of the Earth. Each satellite acts like a dynamic router to these virtual cells. Each satellite also has six open optical links at 20 THz to nearest neighbor satellites in the network. Each 20 ton satellite therefore is capable of connecting with a large number IEEE 802.11y *type* chipsets. http://en.wikipedia.org/wiki/IEEE_802.11y 864 satellite neetwork consisting of 24 satellites in each of 36 orbital planes - each satellite weighs 20 metric tons. These fly in sun-synch polar orbits and provide broadband coverage for the whole planet - supporting 50 billion broadband channels simultaneously. The project I envision entails the development of a spacecraft capable of putting 1,000 tons into LEO. (and 480 tons plus propellant for positioning maneuvers into SSPO) http://www.scribd.com/doc/24390383/mokaerospace-3 A fleet of five of these vehicles are capable of putting up 3 collections of 24 per month - populating the entire network in 12 months. US News and World Report estimated the revenue possible for such a Teledesic network, which is far smaller, to exceed $85 billion per year. With greater bandwidth and lower power requirements (we have what amounts to a radio telescope on orbit with a very sophisticated FFT analyzer on board) we provide more capability for less money - which everyone likes. Basically, every single cell phone, lap top, HDTV screen would be equipped with a broadband chipset for $10 - and charge $1 per month to activate it. Sales of hardware would earn $20 billion per year, sales of basic services would earn another $65 billion per year. $85 billion per year over the 20 year life of the satellite network is worth $937 billion - when discounted at 6.5% - with usual price of living increases the network is worth $1.4 trillion the day its switched on. When you communicate EVERYWHERE it doesn't matter where you are and where you are not. Also, having the ability to communicate everywhere gives you the ability to DEVELOP EMERGING MARKETS CHEAPLY. So, you can have massive increases in service. Here are some possibilities; (1) Provide builders - Chinese or Indian - of satellites and handsets - with bandwidth as partial compensation for services. Giving China 1 billion channels free of charge for 20 years - is worth $240 billion - and helps develop the information infrastructure in that nation - and gets our handsets and hardware for nearly free. (2) Develop new services on the backbone you've erected. This includes (a) banking services - $1 trillion per year earned here - microbanking (b) mediation services - $1 trillion per year earned here - microlegal (c) insurance services - $1 trillion per year earned here - microinsure (3) Develop new technologies around the backbone you've erected. (a) Virtural Tourism - to the 1 billion wealthy - $200 billion/yr (b) Tele-robotic workers - to the 3 billion under employed - $20 trillion/yr The fleet of five vehicles is also capable of providing tourism to the moon, and establishing a village on the moon and an outpost on Mars, while also orbiting solar power satellites. The fleet and launch infrastructure will cost $27.2 billion to build and operate the satellites will mass 17,280 metric tons. At $10 million per metric ton the satellite network will cost $172.8 billion. The total $200.0 billion. A five year program will cost; with launches in the last year $1,325 billions value at switch on Annual Return at 40% ROI COST AT STARTUP billions billions $20 $108 YEAR 1 $30 $115 YEAR 2 $40 $110 YEAR 3 $50 $ 98 YEAR 4 $60 $ 84 YEAR 5 $200 $515 TOTALS 38.83% OWNERSHIP OF REVENUE So, the way this would work is a sponsor would organize the core technology and vision, and jump through all the regulatory hoops, and as they proceeded would sell interests in the revenue generated by the asset they built owned and operated. And this is the value based on the basic service to the 2 billion well- heeled folks around the world. Added value is created by the value added services mentioned, and success with the first step, provides the revenue for other steps (including power satellites, space tourism, lunar cities and mars outposts) So, this is definitely doable - once the basic financial and regulatory structure is setup around the improved technology I've developed. |

David Spain said, "Problem is that in the most affluent areas that
would actually subscribe, " William Mook replies; The world is rich enough to subscribe generally. Average global income is $10,350 per person per year. RANK INCOME PEOPLE SERVICE PACKAGE Low income: $1,407 1.5 billion $1/year - 2 MHz - $20 handset Middle income: $6,157 3.8 billion $1/month - 10 MHz - $200 netbook High income: $37,141 1.5 billion $12/month - 60 MHz - $2000 laptop With 33% market penetration $85 billion per year is earned. There is also an advantage to global penetration in that there is a seamless path to growth worldwide. David Spain writes; "Of course Mr. Mook was proposing LEO sats in polar orbit. A start-up company was founded in the early 90's to do just that (Teledesic). But it would appear the NRE costs to get to orbit, the prior commercial failures of Iridium and Globalstar and the fact that by the time the system would come on-line similar if not better performing systems would already be available to celluar customers, forced Teledesic to suspend construction work on their system on October 1, 2002. " Mook replies: There is a natural progression in capabilities from (1) point to point communications (Telstar), (2) one to many satellites (DirecTV and Sirius), (3) many to many (Teledesic, Iridium) Time to market and cost of space access is important. I spoke with Craig McCaw about this back in 1995. I said that he needed to spend as much developing low cost space launch as he did satellites. He disagreed. He thought that (a) adding space launch development to his tasks multiplied risks; and (b) delayed development; and (c) increasing demand for launch would lower cost of expendable vehicles I pointed out that increasing demand for expendables would raise costs since all commercial costs were subsidized heavily and demanding more launch capability than subsidies would support mean rising costs with rising volume, not falling costs. Time to market is very important. This is part of what killed Iridium. Also, redesigning satellites to fit on available launchers, reduced capabilities. Finally, rising costs meant very high priced services. The ONLY way to make this natural next step in communications work is to develop a commercial launcher of adequate size, get it flying, and THEN design the best available satellite network. The way to do that is to build a large RLV for space tourism, and then use it to launch your satellite network - once development is paid for by the tourists. http://www.scribd.com/doc/24390383/mokaerospace-3 |
