Overview
• Statement of Purpose:– To form a plan for a series of Mars
missions utilizing nuclear energy, which, through technological verification, will allow subsequent capability expansion and finally for a manned mission to Mars.
02.20.03 MIT : NED : 22.033 4
Requirements and Constraints
• Demonstrate feasibility of nuclear powered space propulsion
• Allow safe transport of humans to and from Mars
• Expand the scientific capacity of individual missions
• Reduce astronauts’ radiation exposure• Deployable by near term• The technology is transformational
02.20.03 MIT : NED : 22.033 5
Mission Objectives
• Total of 4 missions are planned.• Manned missions will be scheduled
to reduce exposure in CGR

Mission 3
• Manned Mission Precursor– Development and Demonstrate
Infrastructure to prepare for arrival of the human crew.
02.20.03 MIT : NED : 22.033 15
M3 Objectives
- Define a robust planetary surface exploration capacity capable of safelyand productively supporting crews on the surface of Mars for 500 to 600 dayseach mission
- Define a capability to be able to live off the land
- Ensure Infrastructure is operational before a crew is committed to the site
02.20.03 MIT : NED : 22.033 16
M3 Phase 1• Launch a full
scale NP ISRU Plant
• Demonstrate Large Scale ISRU on Mars
02.20.03 MIT : NED : 22.033 17
M3 Phase 2
• Launch Crew Habitat Module into LEO after successfully completing Phase 1.
02.20.03 MIT : NED : 22.033 18
M3 Phase 3
• Dock Habitat with ISS
• Test Habitat Functionality at the ISS
02.20.03 MIT : NED : 22.033 19
M3 Phase 4
• Ascent Vehicle and Cargo is landed on the Mars surface near Large Scale ISRU plant
02.20.03 MIT : NED : 22.033 20
M3 Phase 5
• Power Systems and Rovers are Deployed
• Production of Propellant and Oxidizer Begins
• Ascent Vehicle Fueled
02.20.03 MIT : NED : 22.033 21
M3 Phase 6
• Unmanned Surface Habitat landed on Mars
02.20.03 MIT : NED : 22.033 22
M4 Objectives– Land people on Mars and return them safely
to Earth.– Effectively perform useful work on the
surface of Mars.– Support people on Mars for 2 years or more
without resupply.– Support people away from Earth for periods
of time consistent with Marsmission durations (2 to 3 years)
– Identify space transportation and surfacesystems consistent with objectives at affordable cost.
