- Introduction by Jeff Moore, review of three issues to be addressed
- Consider the desirability of a separate, parallel Mars program (as it is currently)?
- Tempo and goals of the sample-return-directed "Mars Exploration Program" (MEP)
- New Mission road map (Scott Hubbard era)
- Input to the importance of the Scout program relative to the MEP
- Synergy with science at other targets
- First point raised regarding separate, parallel Mars program
- Donald Bogard: Increasing pressure to not put a fence around Mars program
- Donald Bogard: Mars program is a unique situation - great deal of resources placed on one object for long term
- Jeff Moore: Discussion regarding funding problems and delays gathered from "NASA Watch"
- MEP dropping 09 mission, 05 slipped to 07. . .
- Jeff speculates government will not alter this years NASA budget and will sort out changes next year.
- Discussion on strategy for studying Mars, Donald Bogard makes the following points:
- Need to understand Mars more broadly
- Idea of life on Mars has torqued the emphasis of exploration
- Concerned about the growing complexity of the sample return issue, concerned about being programmatically locked in to preconceived notions about what Mars is like in context of science objectives
- Necessary to identify what we think we can do and what we can afford
- Jeff Moore: MEP to what extent are we oriented toward sample return?
- Allan Treiman: Sample return is the ultimate part of MEP
- Actuality of sample return continuously pushed into the future
- Risk in strategy, long term strategy will not give us as broad based study as discussed 5 years ago
- Sample return essential part of strategy
- Jeff Moore: Is MEP no longer committed to sample return?
- Roger Clark: Discussion regarding data from TES (implications for finding aqueous deposits)
- Speakers Unknown: Discussion on Astrobiology
- Great danger in sending mission w/expectations for finding material (for astrobiology) and it is not found
- Speakers Unknown: Discussion about Mars being a volcanic planet
- Jeff Moore: To what extent do we commit ourselves on sample return?
- Jeff Moore: If we are not seeing aqueous deposits, do we propose another possibility?
- Nadine Barlow: Sample return will pin ages on Mars
- Speaker Unknown: Sample return portion will provide more meaning to everything else we are doing
- Jeff Moore: Issue is sample return is expensive and complex
- How do we articulate our view? and concerns?
- If no aqueous deposits limited funding may become an issue
- Allan Treiman??: JPL has created greater complexity than need be for sample return grab sample appropriate
- Jeff Moore: There are interesting samples on Mars whether they are aqueous or not
- Need to articulate that Mars is an interesting place whether or not they find aqueous deposits
- We should not focus on one kind of (or a preconceived) Mars
- Do not render decadal planning obsolete with preconceptions.
- Jeff Moore: Look at Don Bogards twenty most interesting questions we have on Mars. Do they fit in the present road map? Are they being addressed, why and why not?
- Discussion: Should we open our issue to the public, post them on web site?
- Jeff Moore: SCOUT Program do we slow down the MEP to keep SCOUT program going? Is SCOUT all but dead? Do we want to resuscitate?
- Explanation of what Discovery program was going to handle while SCOUT picked up on other interesting Mars questions
- John Wilson: Discovery program biased against Mars program??
- Speakers Unknown: Discussion about prejudice of doing Mars work through the Discovery Program (NASA insists there is not a bias)
- Jeff Moore: Seriously concerned SCOUT may die / if this is undesirable then MEP may be further slowed to support SCOUT - any alternatives?
- Roger Clark: Few things done well rather than many little things done poorly. . .
- Discussion Speakers Unknown: Go with the best science whether out of SCOUT or MEP
- SCIENCE BASED FLEXIBITLY (agreed upon)
- Philosophy: certain SCOUT Missions flown in terms of when? And based on quality of science.
- Jeff Moore: Last Issue: Synergy of Mars science looking at other planets.
- Separate rationalization of Mars exploration from Life or H2O . . . reasons for studying Mars that go beyond merely "following the water"
- If we arent seeing aqueous deposition Mars, we need a well thought out series of sequentialized science goals to fall back on
- Speaker Unknown: Mars is an analog for the terrestrial planets
- Jeff Moore: Fairness issue: How do we strike a balance between exploration on Mars vs. other planets?
