  Why Do MarsPlans Gather Dust? • Sticker shock!!! (dates back to the 1960’s) • Attempt to extend Earth-dependent architectures to Mars • Reliance on technology breakthroughs • Assumption of reduced launch costs • Inability to sustain over multi-decade execution
• 3.
  Why “Affording Mars”Workshops? • Many critics like to casually cite very large numbers: “trillion dollar Mars mission” – US policy has shied away from Mars in part because of the perception of very high cost – Multiple independent design studies – albeit preliminary – support the affordability of initial human missions to Mars • Significant involvement by broad community of stakeholders will be critical for successful Mars exploration – Significant background reading, planning, and briefings – Participants intended to be representative of stakeholder communities 3

  Priority Consensus Recommendations SummaryAdditional Recommendations 9 • Initial human missions to the surface of Mars should include elements necessary for eventual establishment of sustainable surface outposts broadly analogous to the initial phases of science-guided Antarctic exploration on Earth. • The workshop concluded that a robotic sample return mission may be required to learn how to protect against forward and backward contamination before humans land on Mars • Human missions to Mars orbit or the martian moons may be essential for risk reduction as immediate precursors to surface missions • Human operations on the lunar surface, including landing, mobility, power, and environmental control and life support systems (ECLSS), are not required in advance of initial human Mars missions
