HQ report

• The ESA-NASA August agreement was presented to
  the SSAC and to the SPC. Both bodies expressed
  their satisfaction for the achieved framework
  that allows the project formulation to start
• The LPF project is underway
• The first meeting of the LPF Steering Committee
  took place at Estec recently.
• France has expressed its interest in
  participating to the LTP (with the AOM) - and
  consequently to LISA.
• Details are being finalised and the multilateral
  agreement will be updated to reflect this change

HQ report

• LISA is firmly set in the Cosmic Vision
  programme the authorisation to proceed with the
  MF by SPC, IPC and D-SCI is a clear sign of the
  importance of the mission in ESA
• The LPF MOU is being worked
• Work for the update of the LISA LOA will start
  soon
• ITAR issues are considered very critical
• all cooperative activities with NASA on LPF (ST7)
  have been suspended until ITAR issues are
  resolved and JPL will be able to deliver
  essential documentation to ESA
• Cooperative activities on LISA could be
  dramatically reduced or suspended unless ESA can
  have timely access to project documents that are
  indispensible for the implementation of the
  August agreement

ESA-NASA Agreement

• Following a year of discussion, a programmatic
  agreement for the LISA project has been reached
  between ESA and NASA in August 2004
• The main elements of the agreement are
• Project description
• Project organisation
• System Engineering functions
• Mission elements share
• The Project description defines the general terms
  to be adopted throughout the project

7
Programmatic

• The project organisation is as follows

8
Programmatic

• In the structure foreseen for the Mission
  Formulation phase, a Joint Project Management
  Office (JPMO), led by the NASA and the ESA
  project managers, is in charge of the overall
  project
• The ESA and the NASA project managers share equal
  responsibility in the management of the project
• The JPMO has to approve, inter alia, the mission
  reference design and the requirements
• The project will adopt, as far as possible, a
  single set of procedures, documentation and
  reviews

9
Programmatic - SW

• The agreement for SW includes the following
• Software algorithms and the corresponding code to
  the level of e.g. MatLab routines will be defined
  and maintained by MSE throughout the mission
  lifetime.
• Each Agency will independently verify and
  validate all mission software developed by the
  other Agency.
• Each Agency will exchange models required to
  support design, verification, validation and
  operations with the other Agency.
• If any of the points above requires specific
  clearances, NASA will promptly start the required
  process.
• The last point is a continuous matter of concern
  to ESA and recent repeated experiences have shown
  that it could well be a show-stopper for the
  cooperation

10
Programmatic

• The description of the System Engineering
  functions constitutes a fundamental step forward
  in the cooperation
• it identifies the functions in Formulation and in
  Implementation
• it sanctions the principle that the mission
  design has to be done jointly, to the level
  required to clearly define the responsibility of
  each agency
• It establishes that decisions affecting the
  project cannot be taken unilaterally by one
  Agency
• The implementing structure foresees three SE
  managers working together to define mission
  requirements and reference architecture, to be
  submitted to the approval of the two project
  managers

11
Share of responsibility

• The agreement also contains the following share
  of responsibility for deliverables for the
  implementation phase
• ESA develops the three LISA Opto-mechanical Core
  Systems (LOCS) with contributions from NASA -
  and verifies them individually
• JPL develops the three LISA Instrument Metrology
  and Avionics Systems (LIMAS) with contributions
  from ESA - integrates them to the three LOCS and
  verifies that they function together as a 3-arm
  interferometer before and after integration onto
  the spacecraft buses.
• GSFC integrates each LOCS/LIMAS assembly onto a
  spacecraft bus to form a sciencecraft, adds the
  constellation software, verifies that the three
  sciencecraft, individually and together, fulfill
  the performance requirements
• Procurement of flight micropropulsion elements
  will be decided at a later stage depending on
  technology maturity.

12
Mission Formulation

• ESA will start an industrial contract for Mission
  Formulation on January 17, 2005
• The activity will last two years and is divided
  into two phases, lasting respectively 7 and 17
  months
• The activity is based on the Top Science
  Requirements (Iss.1 - 15 March 2003) and the
  derived MRD
• Regular Milestones have been set to ensure
  consistent system design and to phase work with
  NASA
• Each phase is concluded with a review (Mission
  Architecture and Mission Definition Review
  respectively)
• Additionally, a Mid-term Review will take place
  in the middle of phase 2

13
Mission Formulation

• Mission Formulation has a different meaning at
  ESA and at NASA and care will have to be
  exercised to avoid confusion

15
Mission Formulation

• The MF contract will be lead by Astrium GmbH,
  that will bring their experience on the payload
• Astrium Ltd. will support for all spacecraft
  system and mission issues
• Other contractors and consultants will be pulled
  in at a later stage if and as required
• The contractor primary interface point will be
  the ESA project team
• The contractor will work in close cooperation
  with the NASA team and will participate to
  meetings, as required.

16
MF tasks

• Astrium will support ESA in the consolidation of
• Mission constituents and their interfaces
• Model philosophy
• Error budget apportionment and allocation to the
  constituents
• Risk assessment and risk management plans
• Mission Requirements in order to allow entering
  the Definition Phase
• All the other elements required to support
  discussions with NASA on the share of
  responsibility

17
MF Phase 1

• The objective of this phase is to consolidate the
  LISA mission architecture and design.
• Main end products will be a complete set of
  draft Specs for the LISA mission elements, the
  DDVP, Budgets, Tech Plan
• Among others, the following specific points will
  be addressed in phase 1
• OB re-design and interfaces with IS
• telescope and structure
• Telescope pointing system
• P/L Avionic and I/F with S/C
• Error budget
• Constellation acquisition
• point ahead
• Critical review and analysis of the S/C and
  Propulsion Module design
• Mission scenario and Operations

18
MF Phase 2

• A reference design (mechanical, optical,
  electrical) for the mission elements will be
  produced.
• Product Tree, IRDs, Functional diagrams, Budgets
  will be consolidated
• Risk assessment and margin policy will be
  reviewed
• Environmental constraints will be reviewed
• Key technology identified and technology plan
  proposed
• MRD will be finalized and draft requirements
  documents for the mission elements will be
  prepared
• The requirements verification logic and methods
  will be established

19
MF Short term

• Short term (3 months scale) activities will
  concentrate on the following major architectural
  issues that have relevance in the definition of a
  set a requirements for the design
• Use of Telescope/CCD as a Star Tracker
• Acquisition and attitude control
• Alignment
• Point ahead angle
• Telescope design

20
Data Processing

• European plan of activities
• Request Letter of Intent from interested parties.
• Plan to have algorithm in prototype form at the
  end of 4 yrs period.
• Need to the define the e2e data processing cycle
  with responsibilities and products at the various
  stages.

21
Data processing
1. Create ad-hoc data processing structure with
ESA chair 2. Define goals, plan of work,
schedule 3. ESA request sci community
LoI 4. Selection of scientists for participation
to data processing structure 5. SPC info paper
6. Mtg with selected parties to define plan of
work and required funding 7. Selected parties to
obtain national funding 8. ESA to place a
contract to study and define the LISA data
processing architecture (March IPC)
22
ST7 - DRS

• ST7 is currently undergoing a financial
  replanning that may imply some descoping
• The LPF project is working under the assumption
  of receiving a full ST7-DRS package
• Modifications of the current agreements are
  considered to have programmatic and scientific
  impact to LPF and LISA
• It is therefore recommended to maintain the
  current ST7 baseline
