Orbital Fuel Depots


 

NOTE; This is an email written by Peter Garretson giving a good overview of current studies for Orbital Fuel Depots.
 
Subject: #1 LEO Propellant Depot

 

The first, and most transformational in my opinion is a propellant depot (probably water) because it so broadly enables so many different things:
 
1) Nodal LEO logistics architecture
 
2) Regular, predictable launch rates & number of times we access space
    -- Lowering costs by economies of scale, stable production lines
    -- Lowering costs by demonstrating reliability on low-cost cargo (for insurance
 
3) Allowing users to "Dry Launch" and bring greater payloads to destination (GEO, Moon, Mars)
 
4) Allowing customers to do on-orbit refueling
 
If the US wanted to make a strategic decision to develop space commercially, a propellant depot should be a centerpiece, and subsidization of regular launch of propellant to space ought to be at the front end of consideration.
 
Here are some resources to shape your thinking:
 
- I'm attaching a paper by Greg Allison on how a water-based fuel depot could enances ESAS evolution and expedite Earth-orbit Economic enhancement.  He can be reached at: Gregory Allison [ghallison4space@yahoo.com]
 
- Like Greg, Mike Snead, who recently retired from AFRL and worked extensively with our office has given great thought to space logistics and an architecture with a central "water economy" fuel depotI'm attaching one of his papers.  More resources, including some great explanatory videos here: http://mikesnead.net/resources-spacefaring.htm  Highly recommend you have Mike come brief you, his e-mail is: spacefaringamerica@gmail.com
 
- Lastly, I'm attaching the paper by Dallas Bienhoff from Boeing about a Depot contingent up on Falcon delivery and what it could mean to exploration.  Boeing has done a lot with the Space Commerce Roundtable looking at future markets.  If you have not, I recommend you get the briefing.  I'll shoot a note to see if Dallas would be open to giving it to you guys.
