  • Exploration mission planners maintain “Reference Mission” or “Reference Architecture”

  • Represents current “best” strategy for human missions

1988-89: NASA “Case Studies”

1990: “90-Day” Study

1991: “Synthesis Group”

1992-93: NASA Mars DRM v1.0

1998: NASA Mars DRM v3.0

  • The Mars DRA is not a formal plan, but provides a vision and context to tie current systems and technology developments to potential future missions

  • Also serves as benchmark against which alternative architectures can be measured

  • Constantly updated as we learn

1998-2001: Associated v3.0 Analyses

2002-2004: DPT/NExT

2007 Mars Design Reference Architecture 5.0

National Aeronautics and Space Administration


Mars design reference architecture 5 0 forward deployment strategy

Mars Design Reference Architecture 5.0Forward Deployment Strategy

  • Twenty-six months prior to crew departure from Earth, pre-deploy:

    • Mars surface habitat lander to Mars orbit

    • Mars ascent vehicle and exploration gear to Martian surface

    • Deployment of initial surface exploration assets

    • Production of ascent propellant (oxygen) prior to crew departure from Earth

  • Crew travel to Mars on “fast” (six month) trajectory

    • Reduces risks associated with zero-g, radiation

    • Rendezvous with surface habitat lander in Mars orbit

    • Crew lands in surface habitat which becomes part of Mars infrastructure

    • Sufficient habitation and exploration resources for 18 month stay

Crew and cargo transportation to leo

Crew and Cargo Transportation to LEO

  • Crew Delivery to LEO

    • Provide safe delivery of crew to Earth orbit for rendezvous with the Mars Transfer Vehicle

  • End of Mission Crew Return

    • Provide safe return of crew from the Mars-Earth transfer trajectory to Earth at the end of the mission

ARES I / ORION

ARES V

  • Heavy-lift Cargo to Low-Earth Orbit

    • 130+ t per launch

    • Large volume

    • 30 day launch centers

  • Total Mass in Low-Earth Orbit

    • ~ 800 t for NTR (7-9 launches)

    • ~1,200 t for Chemical (9-12 launches)

National Aeronautics and Space Administration


Mars design reference architecture 5 0 surface exploration and discovery

Long surface stays with visits to multiple sites provides scientific diversity thus maximizing science return

Mobility at great distances (100’s km) from the landing site enhances science return (diversity)

Subsurface access of 100’s m or more highly desired

Advanced laboratory and sample assessment capabilities necessary for high-grading samples for return

Human exploration of mars key challenges

Human Exploration of MarsKey Challenges

  • Landing large payloads on the surface of Mars

  • Launch of large mass, large volumes to Earth orbit

  • Support of humans in space for extended durations including radiation protection and low-g countermeasures

  • Lack of resupply and early-return aborts

  • Maintenance and storage of cryogenic fluids for long periods

  • Production of consumables at Mars (ISRU)

  • Extended mobility of 100’s km

  • System reliability, system reliability, system, reliability


Human exploration of mars evolutionary strategy

Human Exploration of MarsEvolutionary Strategy

  • Zero-gravity countermeasures

  • Gravity sensitive physics

  • Long duration system performance

  • Simulation of operational and mission concepts

Knowledge / Experience / Confidence

Earth/ISS

Moon

Mars via Robotics

  • Demonstration and use of Mars prototype systems

  • Large-scale systems-of-systems validation

  • Surface exploration scenarios and techniques

  • Long-term exposure of systems to the deep-space environment including radiation and dust

  • Long-term “dry run” rehearsals

  • Gathering environmental data of Mars
