Terrestrial and Cislunar exploration technologies Terrestrial and Cislunar exploration technologies, a veteran owned concern DUNS # 967877254 Steven Rappolee 810-334-4374 3501 North River RD, Apt 204H Ft Gratiot, MI 48059 3/20/202 (C) Rappolee 2009/2011 1 5
mass produce MER to fly a rover network utilizing a commercial data purchase agreement
It is believed that the best most cost effective way to do science is to mass produce science space craft The first few mass produced spacecraft would have NASA as a 100 % anchor tenant NASA would be a minority anchor tenant on later missions All missions are data sells over many years
Year 1 2 3 4 5 6 7 8 10 11 Two spacecraft Four Six Eight Ten 2 X $30 Million per year 4 X $30 Million per year $ 120 M 6 X $30 Million per year $ 60 M $180 M $ 240 M $300 M 60 120 240 360
10 spacecraft at $30 million per year each at ten years per space craft 1 2 3 4 5 6 7 8 9 10 60 120 180 240 300 360 420 480 540 600 240 360 480 600 720 840 960 1080 540 720
MER billing cycle 10 spacecraft at $300 Million each is $3 Billion, launched two at a time every two years. Each spacecraft is billed at $30 Million per year for ten years after successful landing and operations for 90 days, so the $3 Billion would be payable over a 20 year period. At year ten this would be $ 300 Million per year and leveling off and declining for ten more years. We could however continue flying two new spacecraft every two years for a sustained campaign. 20 spacecraft at $300 million each billed over three ten year installments, $ 6 Billion.
Red Dragon-externally deployed MERs Curiosity externally deployed MER EDL involved a spinning spacecraft, at atmosphere interface two tungsten weights are jettisoned; close to landing as the spacecraft begins vertical descent, 6 more tungsten weights are jettisoned! Does the Red Dragon spin during EDL? (no) We propose three externally mounted Mars Exploration rovers on Dragon; they would deploy as Dragon goes subsonic. A wasted opportunity? Three MER with only parachutes and airbag landing systems. ISRU and one MER onboard internally
Falcon Heavy can inject to mars a Dragon/trunk docked with an additional Dragon capsule! Two X 4 MER,s 8 rovers Docked Dragon separates and performs a EDL; second Dragon/trunk performs another targeting maneuver, separates trunk and performs a second EDL After MOI Dragon/Trunk separates from third stage and performs a docking maneuver with a Dragon attached to third stage How much internal weight payload is lost to the externally deployed MER,S ?
Multiply landed MERS go their separate ways Red Dragon lifts off to deliver a MER to a selected target; repeat at least 3 times to move the 3 MER further apart Parting ways increases science while the Dragon ISRU works to make fuel Meanwhile in a target many hundreds of kilometers away the second Dragon capsule has landed .***
Option two! Two Dragons same landing site Land RED dragon ISRU first Land one dragon with one MER and ISRU ISRU weight priority over MER payload; why? Land second Dragon with Wolf trap and curiosity science instruments near the first Dragon. 1 ton payload to mars surface under the 3 mile MOLA may violate the decadal survey landing site committee. Fetch MER rovers bring samples back to the science Dragon This may mean that engineering constraints on the red dragon proposal will not allow 1 ton below that limit.
