The request for proposals is out!
The intent is that the SMD ( science missions directorate ) would work closely on these missions and fly instruments, but some of the payload would be ESMD (exploration systems directorate) payloads. ISRU comes to mind,however ISRU could be used in a mars sample return mission so here is my proposal that extends to yet another new proposed line item, the cryogenic on orbit fuel storage/transfer and the aeroshell.
aeroshell is being offered in the discovery AO.
so here is my idea, please critique me.

A Centaur or Delta upper stage is modified to both launch a interplanetary payload and to use residual fuel to power a fuel cell and batteries.My destination is Deimos to satisfy the ESMD folks, and the use of the upper stage to power the payload using its residual fuel is a demonstration of the proposed fuel depot line item.

The payload would include a communications relay for current and future mars robotic probes.The payload would have its own solar arrays and would separate from the Centaur and its solar shade, its long term fuel storage and conversion to fuel cell for power mission over.The Centaur then would vent any remaining consumables and impact Deimos to provide data to the science payload.

After the long term storage of cryogenic fuel is demonstrated on a robotic precursor mission, it could be used next in this scenario, http://www.facebook.com/LoriGarver?v=app_2...69&topic=63

If it is required that any outer planet science probe uses solar arrays and the aeroshell for orbit insertion, it may be required that the solar array must remain stowed behind the aeroshell, so I propose that when the cryogenic upper stage storage technology matures that this would be our power source for the probe in till just before aeroshell orbit insertion. I would think that a cryogenic upper stage could last at least in till orbit insertion to Jupiter.The cryogenic upper stage aeroshell stack could allow a robust Jupiter mission to include a lander

and again the upper stage would impact a outer planet moon for science observations like LCROSS or perhaps fly a brief mission extension of its own.

Thanks - I hope you will post similar links as they come up, it's very useful to have people looking out for things. And regardless of an connection to future human exploration, if these are robotic missions we can discuss them here. I hope the MOOs will provide customers for some of these companies like Astrobotic or Odyssey Moon in future.

Phil
