Integrated Plan for Phase-A

• Completed the integrated phase-A planning
  exercise. Tasks defined to
• Complete mission architecture definition
• Mature Technologies to appropriate level for
  phase-A to B transition
• Develop the project infrastructure
• Conduct grassroots and independent mission cost
  estimates
• Plan accounts for ESAs architecture development
  process with Astrium
• TIMs planned at appropriate intervals for
  coordination with ESA/Astrium to make
  architecture decisions
• Results is a scheduling tool that can be used to
  optimize the project plan in response to budget
  realities

3
INTEGRATED TECHNOLOGY PLAN

• Initiated the integration of the NASA/ESA
  technology development plan
• An integrated outline has been agreed upon
• Identifies division of responsibilities
• Documents expected performance levels to be
  achieved during phase A and Phase B
• Accounts for the technology maturity already
  achieved by LISA Path Finder and ST7
• Expect to have a first draft by end of December,
  2005

LISA Cost History
5
Tracking the History of LISA Cost Estimate

• Initiated a thorough look at assumptions behind
  original TRIP numbers subsequent changes to the
  NASA cost estimates.
• LISA cost growth since the TRIP report is due to
• Changes in launch dates
• Non-optimal budget guidelines relative to TRIP, a
  consequence of the yearly POP process
• Increase in the launch vehicle cost predicted by
  KSC
• Adjustment for NASA/ESA agreement of August 04
• Adjustments for the NASA Technology Development
  plan

16
Updated NASA Cost Estimate

• Started with the TRIP cost estimate
• Assumed TRIP cost profile
• Adjusted TRIP estimate for
• NASA/ESA share of responsibilities
• Launch date
• Assumption that optimum profile will be funded
• Identified areas where cost estimates can be
  adjusted down prior to the grassroots exercise
• Better assumptions for the launch vehicle cost in
  the out-years, based on current missions
• Mission and Science Operations
• Advancement in technology development via Path
  Finder
• Progress being made before Year 1
• New cost estimate will be reflected in the next
  POP cycle

Latest Cost Estimate

FY06 Budget Allocations

• FY06 Budget 2M less than planned for in POP-05-1
  (9.4M vs. 11.8M).
• This is effectively a reduction from FY-05 budget
• Programmatic Impacts
• Technology Development will be further delayed
• Some core team members may not be fully supported
• Prioritized the FY-06 activities to maintain
  proper balance between technology development and
  engineering activities

19
ESA Mission Formulation study

• Industrial study with Astrium GmbH, started jan
  05, is ongoing
• Provides inputs for discussions with NASA on
  baseline architecture
• Areas addressed so far
• End-2-end data flow
• Point-ahead angle
• Telescope
• Actuation mechanism ..
• More will be addressed next week at the TIM
• More details in SE presentation

20
MAR

• Mission Architecture Review held in October at
  Estec at the end of phase 1 of the MF contract
  with Astrium
• Contractual milestone with Astrium and review of
  current baseline with NASA
• Data package available ahead and reviewed by ESA
  and NASA
• Review goals met, phase 2 kicked off
• Astrium currently addressing mass reduction
  exercise
• Next MF milestone will be the Mid-Term review in
  April timeframe

Shorter armlength assessment

• The project has recently received the request
  from some members of the scientific community to
  analyse a mission configuration option with a
  shorter armlength than the baseline 5 MKm
• ESA is willing to instruct Astrium to perform a
  parametric analysis considering i.e. armlength,
  laser power, telescope diameter etc.
• This activity could be performed in the January
  timeframe, providing the request is confirmed by
  the LIST
• Specifically, the LIST is requested to indicate
  whether
• The shorter armlength is an acceptable option
  from a scientific point of view
• What is the approximate range that the LIST
  recommend considering
• What is the minimum armlength below which the
  scientific return loses relevance
• The project will in turn assess the relative
  weight of the financial budget components in
  order to focus the assessment on the issues that
  mostly influence the cost.
