Mars Design Reference Architecture 5.0
• New reference document as of July 2009– NASA-SP-2009-566– Uploaded to SVN : References Folder
• 100 pg text describing Design Reference Architecture 5.0– Introduction– DRA 5.0 Summary– Goals and Objectives– Transportation Systems– Surface Systems– Architectural Assessments– Key Challenges– Public Participation
• Also uploaded Mars DRA 5.0 Addendum– 406 pg text more in-depth version of
NASA-SP-2009-566
Austere Human Mission to Mars• Alternate architecture that is a scaled-back
from DRA 5 and might offer lower development cost, lower flight cost, and meet all the current Constellation Mars mission requirements– A minimum mission set that would be
acceptable from a science and exploration standpoint.
• Paper presented at Space 2009 by Hoppy Price, JPL.– Paper uploaded to Repository: References
Folder– Presentation slides also uploaded.
GA Tech EffortsEntry, Descent, and Landing
• Space 2009 paper on a parametric study of the Mars EDL design space.– Entry velocity, entry vehicle configuration, entry vehicle
mass and supersonic deceleration technology were varied– Paper uploaded to SVN: References Folder
Support for One-Way Missions• October 19th article in Houston Chronicle
– “Travel to Mars – on a one-way ticket?”– http://www.chron.com/disp/story.mpl/nation/6673981.html
• “The concept of a one-way mission to Mars has circulated among space buffs for years, with a Houston-based former NASA engineer, James C McLane III, among its chief champions. Apollo 11 astronaut Buzz Aldrin has endorsed the plan.”– Chief, Space Environment Test Division, NASA 1967-1991
• “The one-way option received a boost six weeks ago when theoretical physicist Lawernce Krauss wrote an op-ed in the New York Times that espoused the plan…”– L. Krauss is the director of the Origins Initiative at ASU and author of
“The Physics of Star Trek”
Final Report / Space 2010Proposed final report outline• Introduction & Motivation• Strategy for Life Support, In-Situ
Resource Utilization and Re-Supply• Surface Power Generation and
Storage• Transportation Scenario based on
MSL EDL Tech– Transportation System Architecture– Surface Infrastructure– Concept of Operations
• Transportation Scenario based on Advance EDL Tech– Transportation System Architecture– Surface Infrastructure– Concept of Operations
• Conclusions and Future Work
Topics to be covered• Introduction & Motivation• Key strategies
– Power, life support, ISRU, re-supply, ???• Transportation architecture description
– Launch, Earth Departure, in-space hab, EDL
• Surface infrastructure– Habitation, Power, Mobility,
Logistics/Spares, Assembly, EVA, Comm, Robotics
• Concept of Operations– Launch manifest, surface activities
• Mass chunking scenarios:– 2mt, 5mt, 10mt, ???– Based on trans. Arch.– Affects surf infrastructure and con ops.– Tied in with previous topics?
• Conclusions and Future Work
