The LEO "space tug"
« on: 07/07/2010 07:19 PM »
This thread is to discuss the idea of a NASA operated "LEO space tug". The tug would be used for unmanned Cargo only Missions, both to ISS and in future to higher orbits for BEO "stack building". It could be used by commercial providers as well.

The tug would be a clean sheet design. It can be based on Orion or Orbitals future plan involving cygnus, but the idea would be that said tug could manevur at least 45mt of payload (i.e. it could take that payload from an inital LEO launch orbit and raise to ISS orbit, ect.)

This thread is designed to discuss any and all ideas for this concept, so please be creative :D

Would like to discuss costs and integration options with the SSPDM.

Do any of the FTD missions involve ISS proximity operations?  The "space tug" used for those might be not have the capabilities needed for SSPDM missions.

The Flagship Service Vehicle (FSV) Requirements Capture Document, which specifies a notional payload of 12,000 kg, where the combined stack fits within a long Atlas V 5 m fairing.

For the FTD missions, "That's nice."  On-orbit assembly of anything useful out of 12 t components looks, "Not so nice."  DIRECT (or AJAX) could deploy the same FSV under a larger fairing with a more useful payload.
