MERLIN,PANDORA and PADME as a ARM precursor mission to Deimos and Phobos
suggestions to the 30 June SBAG meeting and to the FAST committee,
Boulders that show image evidence of having rolled downhill might inform us of having lost any connection or cohesiveness to the surface. I wrote that a Boulder could be frozen,sticky(stuck) or cohesion with the surface.The speaker and moderator used the term( fill this in) and the term(fill this in) to describe a boulder made of rubble that might not survive a retrieval attempt or the trip to Distant Lunar orbit.I wrote to the SBAG moderator who asked the question to the speaker my thoughts that a boulder that has rolled downhill in a gravity well has proven it self worthy of retrieval, the moderator suggested that in a micro gravity environment this might be less so. A rolling rock might make for a primary target for a retrieval mission.A boulder that has rolled downhill might have better cohesive structure to be manipulated during retrieval!
The speaker seemed to me when he answered my question not to have considered this idea in his teams work or in his presentation.I have pondered this and I am thinking that the speakers team is only thinking of small asteroids! Deimos and Phobos might be in deep enough gravity fields that you might find rolling rocks?
So that’s it, our hypothesis is that rolling rocks are the best candidates for retrieval based on a greater suitability to remove from the surface and importantly less propellant to loft the retrieved sample from the surface.We would like to submit this as a bases for being accepted onto the FAST volunteer commitee
Rolling Rock beer could donate money to science by flying their logo on the launch vehicle?The Band The Rolling Stones could involve along with beer in public out reach.MERLIN,PANDORA and PADME could be precursor missions for a Deimos and Phobos ARM boulder retrieval mission.In most scenarios the missions would overlap so the precursor mission could image and provide navigation to the ARM. Cubesats such as NEO Scout could also provide support in a joint missions.
We propose new policy here that mimics the ARM funding mechanism.The Human space directorate needs to know Human SKG such as the radiation levels solar and cosmic at proposed human landing site on both martian moons therefore Merlin and the other Discovery AO could be funded from the human spaceflight directorate as well as the science mission directorate. We could fly two Mars moons missions with joint funding, Merlin is the lander so it could fly the radiation experiment(RAD) to the proposed human crewed martian moon crater
This Discovery AO will have runners up and a final winner , if none be mars missions then My idea that several mars moon missions be flown that also carry RAD
This is a study of ARM close proximity operations, we think this would be enenced by close proimty operations with a nearby operational Pandora mission.
We think ARM should be discussed at the mid decade Decadal survey to discuss the idea that ARM should really retrieve a boulder from Phobos or Deimos
EDIT 27 December 2015 , a ARRM derived Phobos sample return,
Steven Rappolee: Do any of these moons have any imaged boulders that have moved or rolled downhill?
