Design Reference Missions (DRMS): Scenarios

• Scenarios and methodologies based on practical knowledge and experience

• Comparison of scenarios to get a sense of and/or optimize our trade spaces as we build our architecture

• They tell usy– How we do– What we do– Why we do

Page 10: Science Enabling Engrg Enabling Science prsntn...Exploration and Science Lunar Robotics Missions ... Space Shuttle Program Transition and Retirement Ares I and Orion Development Operations

The Systems Engineering and Science Perspectives are Similar

• From a science perspective: conceive/define the problem (hypothesis), identify the variables needed to be studied, plan and carry out the methodology to collect data, analyze, validate by observing similarities in other areas, conditions, etc. put the puzzle pieces together

• Consider the complete problem, define needs and required functionality (early in the development cycle), document requirements, synthesize design, verify and validate system

• In doing so, one expects– recognition and minimization or reduction of risks– improvement and guarantee of quality: improve understandability and verifiability; consistent,

repeatable, reliable results– reduction of total cost: applying standardized process obtains uniform, easily retraced results– improvement of communication between all stakeholders: standardized and uniform description

of all relevant elements and terms is the basis for mutual understanding between all stakeholders

List of Questions and Preparationfor Field Geology Trip

• Where is each team member with respect to the other and the point(s) of interest?A th lti l i t f i t t b i b d t ti ?• Are there multiple points of interest being observed at one time?

• Is there a differentiation of macro observation vs. micro observation?• What is the sequence of events, questions asked, etc. ? Is the sequence

repeated at each point of interest?repeated at each point of interest? • Is there a checklist for things to ask, or is it in one’s head? • How does one make sure that one hasn’t forgotten to ask a particular question? • How does one know when to move from one point to another, i.e. what is the

decision criteria for moving from one point to another?• My preparation

An Example of General Surface Exploration Philosophy

• Each mission should explore new territory and continue to push back the frontier

• Each mission builds on previous missions• Each mission extends range and time away from outpost as confidence

is gained in surface systems and operational experienceg y p p• Every mission should plan time for revisits to prior sites based on

discoveries and Earth-based research (e.g., initial reconnaissance can be followed up with detailed investigation)p g )

• Every mission will likely involve local fieldwork (e.g., science station emplacement, regolith studies)

20

Page 21: Science Enabling Engrg Enabling Science prsntn...Exploration and Science Lunar Robotics Missions ... Space Shuttle Program Transition and Retirement Ares I and Orion Development Operations

Basic Geological Field Approach

• Determine temporal relationships from spatial relationships– uses the superposition principle– observe such relationships for exposed strataobserve such relationships for exposed strata

• in impact or volcano-tectonic formations• in surface deposits, such as ejecta or pyroclastic deposits• by traversing regolith for expression of underlying geochemical boundaries, such as flow fronts

• Surface expression of underlying stratigraphy will be found in discernableSurface expression of underlying stratigraphy will be found in discernable stratigraphic contacts and nonconformities

– vertical (crater, volcano-tectonic ridge, scarp, or rille walls)– horizontal (traverse underlying bedding, sample surface outcrops, cross volcanic flow fronts or

impact debris fields)p )

• Ground Truth is currently limited– to a small number of nearside, mostly near equatorial sites– extended by remote sensing and imaging with relatively low spatial resolution (by terrestrial

standards)standards)

• Processes as observed and sampled in these landings sites will utilize– previous limited lunar field work– major contribution from terrestrial analogue studies

Appreciating that Science Enables Engineering Enables Science…

• Provides an understanding of the complexities and subtleties of field study and the accompanying implementation techniques

• The process is not all that different from an systems engineering approach

• Challenges our definition of “success” and the “metrics” by which we g ymake trades for architecture evolution while considering that science is the evolution of discovery

• Take advantage of the opportunity to strike a balance and facilitate one g pp yof the primary reasons for going to the Moon – Scientific Knowledge
