Robert Zubrin advocates for a quick decision by NASA and the National Space Council on a mission using SpaceX hardware to put a Dragon capsule in orbit around the Moon before the end of the year. In a letter to Jim Bridenstine and Scott Pace, he suggests lofting a crew to low Earth orbit in a Crew Dragon using a Falcon 9 launch vehicle. This would be followed up by launching a Falcon Heavy for rendezvous in LEO with its upper stage containing surplus propellant. The Falcon Heavy upper stage could then propel the Dragon to the Moon in an “Apollo 8” type mission ending with a splashdown of Dragon in the ocean.
Only slight modifications would need to be made to the Dragon to carry enough oxygen for a 6 day journey. The capsule is already designed for Earth capture from a Mars trajectory so return from the Moon should not be a problem. Zubrin’s proposal was sent in a memo to the NASA Administrator and the Executive Secretary of the National Space council on June 30, and reprinted in the Space Review July 6. Such a demonstration could inspire the nation and initiate validation of essential cislunar infrastructure toward settlement of the Moon.
