2. mass produce MER to fly a rover network utilizing a commercial data purchase agreement

3. 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

6. 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.
$300 Million per year divided by 2, data services $150 Million, Mars exploration budget $150 Million.

7. Red Dragon-externally deployed MER’s
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!
A wasted opportunity?
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.
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

8. Falcon Heavy can inject to mars a Dragon/trunk docked with an additional Dragon capsule! Two X 4 MER,s 8 rovers
After MOI Dragon/Trunk separates from third stage and performs a docking maneuver with a Dragon attached to third stage
Docked Dragon separates and performs a EDL; second Dragon/trunk performs another targeting maneuver, separates trunk and performs a second EDL
How much internal weight payload is lost to the externally deployed MER,S ?

9. Multiply landed MER’S go their separate ways
Parting ways increases science while the Dragon ISRU works to make fuel
Red Dragon lifts off to deliver a MER to a selected target; repeat at least 3 times to move the 3 MER further apart
Meanwhile in a target many hundreds of kilometers away the second Dragon capsule has landed………….***
Falcon Heavy has an excess in performance to mars Injection with the Dragon/trunk, Dragon/Trunk is 19,500 LBM minus 650 LBM

10. Option two! Two Dragons same landing site
Land RED dragon ISRU first
Land one dragon with one MER and ISRU
Land second Dragon with Wolf trap and curiosity science instruments near the first Dragon.
Fetch MER rovers bring samples back to the science Dragon
ISRU weight priority over MER payload; why?
1 ton payload to mars surface under the 3 mile MOLA may violate the decadal survey landing site committee.
This may mean that “engineering constraints “on the red dragon proposal will not allow 1 ton below that limit.
