Science Management PlanDiscussion
15
FAQ
  • What is the science management plan?
  • Document developed by the Science Team in
    conjunction with ESA/NASA HQ
  • Developed for most ESA missions
  • Describes how the science effort will be managed
  • What are some of the elements that the science
    management plan covers?
  • Definition of the Science Team and Scientific
    Roles for the Mission
  • Investigation Teams/Guest Investigators/Key
    Projects
  • Data rights/Data release/Data centers
  • Outreach, conferences, publications,
  • When is a science management plan needed for
    LISA?
  • Important input for MOU
  • Target Draft by Next LIST meeting

16
Long-Term Schedule Milestones
  • March 06 ESA LISA Implementation Phase
  • July 05 ESA Implementation Phase ITT
  • March 05 NASA Confirmation Review
  • Oct 03 ESA LISA Definition Phase ITT
  • June 03 Signed MOU due
  • New Driver ITT for LISA Definition (Oct 03)
  • Driver Start of ESA LISA Definition (April 04)
  • Driver Revision of 2-yr LOA (Jan 04)
  • June 03 Draft of Science Management Plan
  • Dec 02 Inputs to MOU
  • Draft payload allocation recommendations
  • V1 of science requirements document

17
Elements of the Plan
  • Science Team, Investigation Teams, Investigators
  • How many members on the Science Team?
  • How are the members selected?
  • How long are the terms?
  • Will LISA require Investigation Teams or Key
    Projects
  • If so? How many? What is the scope?
  • How are members of the Investigation Teams
    chosen?
  • Will there be individual Investigators in
    addition to the Science Team members?
  • If so? How many? How are they funded?
  • How will data be distributed? Do
    investigators/science team members have data
    rights?
